An IIT Gandhinagar-Indian Council of Agricultural Research-DRMR study has characterised the self-rejection genes in India’s commercial mustard varieties, toria and yellow sarson. Combining molecular genetics with Artificial Intelligence-based protein structure prediction, the team mapped the four genes that allow some mustard flowers to turn away their own pollen. The study sheds light on a natural mechanism breeders can harness to produce the high-yielding hybrids the country needs to cut its heavy reliance on imported edible oil.
The new method, as well as allowing study of individuals, also reduces the potential for louse faecal contamination. It allows collection of high-quality samples from a single louse per test, with substantial yields of secretory proteins per louse.
Maize production has increased nearly six-fold over the past six decades, but reactive nitrogen losses from maize fields have risen by a similar magnitude. A new study published in Science Bulletin argues that the next step in maize improvement must link yield gains with lower environmental costs.
The researchers introduced the concept of green and efficient, or G&E, maize varieties. These varieties are defined as relative to locally adapted conventional control varieties under comparable management, simultaneously increase grain yield while reducing at least one category of environmental input or reactive loss.
By integrating genetic evidence, reported varieties, field observations and global soil and climate data, the authors found that existing G&E maize varieties already increase yield and nitrogen utilization efficiency respectively by 10.1% and 16.7% on average. Under an ideal full-adoption scenario, such varieties could raise global maize production by 18.1% and reduce reactive nitrogen losses by 26.6%.
