Though science has still not replied to the eternal question of whether tomato is a fruit or a vegetable, it has stepped closer to answering it. The full genome sequence of tomato has been discovered by an international team of scientists, working across nationalities. Not only has the team cracked the genetic code of cultivated tomato but also that of the wild variety. It is being hoped that this development would help farmers grow tastier and more nutritious varieties of tomatoes in the future.

1) The Genetic Code

The full genome sequence of tomato, Solanum lycopersicum, has been named “Heinz 1706” and it has been published in the science journal “Nature.” Describing the details of the genetic code, the scientists said that all the 35,000 genes of tomato are well displayed in this sequence along with their functional parts, orientation, types, and relative positions. The researchers found that the tomatoes were made up of about 35,000 genes, arranged on 12 chromosomes and each of those genes is responsible for any characteristic that tomato shows. The “Nature” article describes the genetic results, “The tomato genome sequence provides insights into fleshy fruit evolution.” Apart from the domesticated or cultivated tomato, the researchers have also been able to crack the genetic sequence of its wild relative Solanum pimpinellifolium. James Giovannoni, who works at the “Boyce Thompson Institute for Plant Research at Cornell University," shows his excitement through words, “For any characteristic of the tomato, whether it’s taste, natural pest resistance or nutritional content, we’ve captured virtually all those genes.” Giovannoni further adds, “Tomato genetics underlies the potential for improved taste every home gardener knows and every supermarket shopper desires and the genome sequence will help solve this and many other issues in tomato production and quality.”

2) The Significance

In the US alone, tomatoes are worth $2 billion pie of the market share and Britain dabbles in $980 million worth of tomato business a year. In the rest of the world too, tomatoes are an inherent part of daily diet in all forms. Therefore, their consumption depends, to a large extent, on their quality. It is no wonder then that the scientists are excited about the possibilities arising out of knowing tomato’s genetic code. One of the main benefits would be for the researchers to identify links between tomato genes and the characteristics like taste, shape, color and nutrition level shown by various tomatoes. The scientists will also be able to pinpoint the specific environmental factors that enhance or affect the overall health of tomato crops. Graham Seymour, a member of the scientific team working on this project, and a professor of biotechnology at the “Nottingham University”, explains, “Tomatoes are one of the most important fruit crops in the world, both in terms of the volume that we eat and the vitamins, minerals and other phytochemicals that both fresh and processed tomato products provide to our diets.”

3) The Team

It was an international collaboration between more than a dozen countries that was named the “Tomato Genomics Consortium” and was entrusted with the responsibility to identify the genetic sequence of this popular fruit/vegetable of the world. The researchers, who were members of this Consortium, belonged to various nationalities, such as Argentina, Germany, China, France, India, Israel, the Netherlands, South Korea, Italy, Spain, Belgium, Japan, United Kingdom, and the US.

4) The Future

It took the international Consortium many years and millions of dollars to find out the first genome sequence in case of tomato. However, the scientists are hopeful that further studies in this direction would yield results at a much less cost because they will have initial findings to work with. Besides, buoyed by the tomato findings, scientists are also ready to work on fruits like strawberries, apples, bananas, etc to identify their genome sequence and work for their improvement too. As Giovannoni explains, “Now we can start asking a lot more interesting questions about fruit biology, disease resistance, root development and nutritional qualities.”

Tomato has many health benefits, especially when eaten raw. Now armed with the genetic information, it is going to be much easier for the scientists to provide significant inputs to the farmers to grow better varieties of tomatoes as well as other fruits and vegetables. As for that cup of salsa, it is gonna get better now!

Tomato Genome Decoded: Researchers To Publish Fruit's DNA Sequence In Full

By: Jennifer Welsh, LiveScience Staff Writer
Published: 05/30/2012 01:07 PM EDT on LiveScience
For years scientists have slaved away, trying to piece together the genes that make up the ripe, red goodness that is the tomato. They have finally published the fleshy fruit's genome in full.
The genome of any species is the DNA code that is stored as a blueprint inside every cell of every individual of that species. The DNA letters, called base pairs, are organized into genes, which are translated into proteins, the building blocks and machinery of every cell.
Decoding these genes can help researchers understand the different types of proteins found in organisms, and how these proteins make that species different from every other species. These kinds of insights from the genome could help crop researchers improve the yield, nutritional content, disease resistance, taste and color of tomatoes, they say.
"For any characteristic of the tomato, whether it's taste, natural pest resistance or nutritional content, we've captured virtually all those genes," study researcher James Giovannoni, of Cornell University, said in a statement. "Tomato genetics underlies the potential for improved taste every home gardener knows and every supermarket shopper desires and the genome sequence will help solve this and many other issues in tomato production and quality."
Generic and wild genomes
The researchers sequenced the genome of the tomato species Solanum lycopersicum, of the variety "Heinz 1706," as their type tomato. These tomatoes possess some 35,000 genes arranged on 12 chromosomes (large arrangements of hundreds of genes packed into one strand), the researchers said.

The researchers also sequenced the garden tomato's wild ancestor, Solanum Pimpinellifolium.
Knowing the sequence of one tomato can help seed companies and plant breeders get a grasp on what makes different varieties, like heirloom tomatoes, different from the generic grocery tomato.
Because the variability between two varieties is pretty small, it's easier to use the Heinz 1706 genome as a guide, and pinpoint the differences that lead to changes in color, taste, texture, size and shapethat distinguish one variety from another.
Tomato vs. potato
The genome is also important in learning why the tomato is so different from its genetic relatives in the nightshade family of flowering plants, which includes the potato, pepper and even coffee. Scientists want to know what genes have changed that gives each of these species their distinct flavor and look.
"Now we can start asking a lot more interesting questions about fruit biology, disease resistance, root development and nutritional qualities," Giovannoni said.
Tomatoes represent a $2 billion market in the United States alone. The USDA estimates that Americans consume, on average, more than 72 pounds (33 kilograms) of tomato products annually. Researchers have even developed a robot tomato harvester to go into space (or just use here on Earth).

The tomato decoded: holds more genes than humans

The tomato has always been a complex fruit. Or is it a vegetable? Either way. Tomato, tomahto, right?
The tomato, which is considered a fruit by botanists and a vegetable to the US government, has been demystified by a consortium of plant geneticists from 14 countries who spent nine years decoding the tomato genome with the hopes of breeding better, tastier fruits.
Specifically, the scientists sequenced the genomes of both Heinz 1706, a variety used to make ketchup, and the tomato’s closest wild relative, Solanum pimpinellifolium, which is grown in Peru, according to The New York Times.
The researchers reported that tomatoes possess some 35,000 genes arranged on 12 chromosomes. "For any characteristic of the tomato, whether it's taste, natural pest resistance or nutritional content, we've captured virtually all those genes," James Giovannoni, a scientist at the Boyce Thompson Institute for Plant Research, told Phys.org

Effects of Hoeing on Standing Crops that Reduce the yield

Hoeing is big issue near farmer to remove the weeds, soil aeration, nitrogen fixing and fertility restoration in standing crops. But on the other hand some factors are studied by the approval of experiments which reduced the plant yield i.e

It cut the adventitious roots- they are the fibrous side root system which take up phosphorus, fix the nitrogen and other macro and micro nutrients from soil which support the plant for growth and development.

When fibrous roots system damaged then plant only depend on main root (tap root). Applicable nutrients are only available on upper soil surface, so plant cannot uptake it.

Hoeing damage the eggs of beneficial insects which are responsible for nitrogen fixing and fertility restoration.

Applicable nutrient move from one place to another.

Hoeing damage the whole plant or some parts.

It disturb the level of soil.

The main objective of hoeing near farmers is only weeds removal and soil aeration. This problem can be solved by using the below suggestion.

• By using recommend weedicide, at the pre emergence stage or post emergence stage for wheat, cotton, sugarcane, maiz, potato etc. weedicide dose can recommended by agrarian decision after field vist.

ü Pre emergence weedicides i.e.
Pandimethelen@1000ml/acre, Acetacholor@500ml/acre, S-metolacholor etc.
ü Post emergence weedicides viz.
Bromoxinal+MCPA@500ml/acre, Cholodenafop@150gm/acre,
Fenoxaprop@500ml/acre, Fluroxypyr + MCPA@300gm/acre,
Isoproturon@800gm/acre, Atlantis@180gm/acre, glyphosate@150ml/16L water,
Paraquat (Gramaxone)@1000ml/acre.

• By using recommended soil supplements at both stages i.e. pre sowing and post sowing.

These supplements improve the soil structure and make a fertile soil for better crop yield.
ü Humic acid, application of this recommended dose chemical in soil at pre and post sowing break the soil hard pan, active the bonded nutrients in soil, soil aeration by softening of soil.
ü By the application of balance macro and micro nutrient at sowing and post sowing time.
This method is very efficient to improve the soil structure and increase the crop yield for the earning of farmers, time saving and for country development.

Mushrooms gain popularity in Germany

The German mushroom market saw some progress in 2011, after a clear rise in 2010. The consumption of industrial mushrooms has been going down for years, a fact that hasn’t changed in 2011. But in general, the market is a positive one, seeing as the sales of fresh mushrooms went up with 2% last year, and 8% before that. Brown mushrooms in particular are gaining popularity.
Over half of the German mushrooms are imported. Domestic cultivation was about 62,000 tons in 2011, some 2000 tons more than in 2010. Both Holland and Poland are the most important suppliers of mushrooms, with 30,000 tons each. Hungary, with just 500 tons, is in third place.

New method to design better greenhouses

Doctorate student Bram Vanthoor of Wageningen UR Glastuinbouw has developed a method of calculation to design greenhouses better suited to local circumstances. The method has been tested for the Netherlands and Spain. During the tests two different greenhouse designs were built fully in line with the local situation. The method offers the possibility to optimise greenhouse building worldwide. Vanthoor will defend his thesis on Friday 17th of June.
Arch greenhouses, parral greenhouses, Venlo greenhouses and wide roof greenhouses, the variation worldwide is enormous. When designing a greenhouse one must also choose between a large number of different construction elements, such as e.g. roofing materials, heating and cooling systems. Which kind of greenhouse the grower chooses and how the greenhouse is being fitted is amongst other things, dependent upon the outside climate, economic factors, legal issues, social circumstances and the presence of sources, such as water, energy and CO2. The choice in favour of one possibility very often has a direct influence on the other elements and also depends on the plants to be cultivated in the greenhouse. This makes it very difficult to optimize the design process.

Optimization design
Bram Vanthoor developed a design method, which dependent on the local climate and economic conditions, designs a greenhouse which supplies the maximum financial result. The method always includes local circumstances and takes eight design elements into consideration, namely greenhouse construction, roofing material, outside awnings, chalk materials, energy screen, heating system, cooling system and CO2 quantity dosing system.

The design method is based on three models, namely one greenhouse climate model, one plant model and an economic model. These models calculate, dependent on the variables supplied, the financial result. After that an optimalisation-algorithm adjusts the design step by step. In this way the financial result is maximised finally and the best greenhouse found.

The design method has been tested in Spain and in the Netherlands. The model was designed quite differently for both locations, but with realistic proposals for the most successful greenhouse in both instances. The Spanish greenhouse had a larger ventilation area and was specially built to prevent high temperatures, whilst in the colder Netherlands a higher working capacity and an energy screen were fitted. It became clear at both locations, that the economic performance of the greenhouse improves by a high percentage of light passing through and that an outside screen, geothermic heating and mechanical cooling make the result worse.

Perspective of the method
The method has in first instance been developed for tomatoes. Adjustment for other
plants is possible. The design method of the greenhouse can assist in optimizing the cultivation of plants in greenhouse further. It is also possible to establish the best location to build new greenhouse with the new approach and the results of the economic changes on the cultivation can be predicted. Bram Vanthoor in the meantime lives and works as a business developer for a horticultural supplier in Mexico. The acquired knowledge is used there to adapt greenhouse to the local conditons.
