Discovery is key to creating heat-tolerant crops

Warmer temperatures signal to plants that summer is coming. Anticipating less water, they flower early then lack the energy to produce more seeds, so crop yields are lower.

“We need plants that can endure warmer temperatures, have a longer time to flower and a longer growth period,” said UCR botany and plant sciences professor Meng Chen. “But, to be able to modify plants’ temperature responses, you first have to understand how they work. So, that’s why identifying this gene that enables heat response is so important.”

Yongjian Qiu, the paper’s first author and former UCR assistant project scientist, now at the University of Mississippi.

The work that Chen and his colleagues did to uncover the heat-sensing gene was published this week in the journal Nature Communications. It is the second gene they’ve found involved in temperature sensing. They located the first gene, called HEMERA, two years ago. Then they did an experiment to see if they could identify other genes involved in controlling the temperature-sensing process.

Less sensitive plants
Ordinarily, plants react to shifts of even a few degrees in weather. For this experiment, the team began with a mutant Arabidopsis plant completely insensitive to temperature, and they modified it to once again become reactive.

Examining the genes of this twice-mutated plant revealed the new gene, RCB, whose products work closely with HEMERA to stabilize the heat-sensing function. “If you knock out either gene, your plant is no longer sensitive to temperature,” Chen said.

Both HEMERA and RCB are required to regulate the abundance of a group of master gene regulators that serve multiple functions, reacting to temperature as well as light, and turning plants green. These proteins are distributed to two different parts of plant cells, the nucleus as well as organelles called chloroplasts.

Going forward, Chen says his laboratory will focus on understanding how these two parts of the cell communicate and work together to achieve growth, greening, flowering, and other functions. “When you change light or temperature, genes in both the nucleus and chloroplasts change their expression. We think HEMERA and RCB are involved in coordinating gene expression between these two cell compartments,” Chen said.

Ultimately, the goal is to be able to modify temperature response to ensure the future of our food supply. “We were excited to find this second gene,” Chen said. “It’s a new piece of the puzzle. Once we understand how it all works, we can modify it, and help crops cope better with climate change.”

Israel announces creation of global seed company

Two Israeli seed producers, Nirit Seeds and TomaTech, have joined forces to create Israel’s largest vegetable seed company. This synergy will enable unique seed breeding research and development that will accelerate the company’s growth in the international seed markets.

Upon completion of the merger, the company will have more than 80 employees worldwide, including molecular biologists, breeders, agronomists, and others.
The company will improve its breeding activities in Israel, Spain, Mexico and Italy, as well as significantly expand its representation in the Netherlands and North America, with a particular focus on growing vegetables in high-tech greenhouses.

Nirit Seeds is one of the most successful internationally traded tomato and pepper seed producers, investing in the development of revolutionary genetic technologies. TomaTech is one of the leading tomato seed companies in Israel, developing premium varieties, including those resistant to the dangerous Tomato Brown Ruffle Virus (ToBRFV).

The production of crop seeds is one of the most advanced and high-tech sectors in Israel. According to the Seed Department of the Federation of Israel Chambers of Commerce, seed exports currently generate $200 million in annual revenue. There are about 25 large and medium-sized companies in the local industry.

For reference. According to market research, the global vegetable seed industry is valued at $8 billion a year and is growing at a CAGR of 8%.

Karachay-Cherkessia became one of the leaders in the production of greenhouse vegetables at the end of 2021

fdQAAAABJRU5ErkJggg==

Greenhouse vegetable production in 2021 reached a record 1.4 million tonnes. According to the Ministry of Agriculture of the Russian Federation, the leaders among the regions in this segment are the Karachay-Cherkess Republic, Lipetsk, Moscow, Kaluga, Volgograd, Novosibirsk, Saratov, Chelyabinsk regions, Krasnodar and Stavropol Territories, the Republics of Bashkortostan and Tatarstan. These regions account for more than 60% of the total production in the country. The intensive development of greenhouse projects in our country helps to provide Russians with fresh vegetables all year round. Last year, the harvest in winter greenhouses updated the 2020 record – more than 1.4 million tons of products were received. Including the production of cucumbers amounted to at least 830 thousand tons, and tomatoes – 590 thousand tons. It is expected that by 2025 the volume of vegetable production in year-round greenhouses will be at least 1.6 million tons of vegetables.
