Chinese scientists develop method to increase crop yields
Experiments conducted under different conditions – both in greenhouses and open fields
Chinese scientists have made a significant discovery in the field of agriculture by developing a new method that significantly increases crop productivity when exposed to high temperatures. This is reported by CGTN, a partner of TV BRICS.
Institute of Genetics and Developmental Biology under the Chinese Academy of Sciences used an innovative gene editing tool to introduce a heat stress-responsive element into the tomato LIN5 gene. This change enhances gene expression at high temperatures and reduces sugar deficiency in the fruit.
Experiments conducted under different conditions, both in greenhouses and open fields, showed that the new technique increased tomato yields by 14 to 47 per cent under normal conditions and 26 to 33 per cent under heat stress, preventing between 56 and 100 per cent of yield losses due to heat.
In addition, experiments with rice have shown that this genetic engineering technique can increase rice production by 7-13 per cent under normal conditions and 25 per cent under high temperatures.
Scientists say these experiments have significantly improved crop resilience to climate change and ushered in a new era of designing high-yielding and stable varieties.

Ashok MondalNID Director"Signing this Memorandum of Understanding between the National Institute of Design (NID) and TV BRICS marks a pivotal milestone in advancing design diplomacy across the BRICS media space. This moment is especially significant as India hosts the 18th BRICS Summit, following India’s assumption of the BRICS chairship under the visionary leadership of Prime Minister Shri Narendra Modi. The partnership directly embodies his call to elevate Indian design standards through 'Design in India, Design for the World'. Through the global reach and broadcast capabilities of TV BRICS, we are excited to showcase the extraordinary visual storytelling, films, and design research of NID’s Film and Video Communication students to an international audience, while also welcoming and screening film works from BRICS network countries at NID Ahmedabad. This reciprocal exchange strengthens our shared commitment to educational, cultural, and artistic collaboration, fostering sustainable connections among global creative communities. NID Ahmedabad looks forward to leveraging this partnership to deepen cross-cultural dialogue, build international expert networks, and unlock transformative opportunities for filmmakers, researchers, and faculty across member nations" -

So, we have an opportunity to lead by example. We have our development bank, which can demonstrate and develop new ways of financing programmes. We can reduce the risks for private capital to invest in restoration and efforts to combat desertification" -
