Tweaking corn kernels with CRISPR
Corn has a highly complex genome, making it a challenge to apply genome-editing techniques to it. CSHL Professor David Jackson and postdoctoral fellow Lei Liu used CRISPR to tinker with the corn genome promoter regions and modify stem cell growth. They figured out which sections influence kernel yield, and they hope to make targeted genome-editing in corn more precise and efficient. (2021-02-22)

Variable weather makes weeds harder to whack
From flooded spring fields to summer hailstorms and drought, farmers are well aware the weather is changing. It often means spring planting can't happen on time or has to happen twice to make up for catastrophic losses of young seedlings. According to a joint study between University of Illinois and USDA-ARS, it also means common pre-emergence herbicides are less effective. (2021-02-08)

Newly discovered trait helps plants grow deeper roots in dry, compacted soils

Illinois research links soil nitrogen levels to corn yield and nitrogen losses
What exactly is the relationship between soil nitrogen, corn yield, and nitrogen loss? Most farmers would be forgiven for assuming a straightforward linear relationship: more nitrogen, more grain yield, and maybe, more loss. That's the assumption many nitrogen management models are based on, but it turns out there's very little published science to back up that assumption. (2020-10-13)

Snakes reveal the origin of skin colours
The skin colour of vertebrates depends on chromatophores. A team from the University of Geneva is studying the variety of colours within the corn snake species. The research, demonstrates that the dull colour of the lavender variant of corn snake is caused by the mutation of a gene involved in forming lysosomes enough to affect every skin colour. The UNIGE study marks a step forward in our understanding of the origin of skin colours. (2020-10-05)

Corn farmers can apply a fungicide just once to protect against foliar diseases
'Our findings suggest that Kentucky corn growers likely can rely on a more cost-effective single fungicide application at R1 for foliar disease management and improve return on fungicide investment rather than making multiple applications at different times,' said Bradley. (2020-10-05)

Can organic plant protection products damage crops?
Protecting crops against pests and diseases is essential to ensure a secure food supply. Around 95 percent of food comes from conventional agriculture, which uses chemical pesticides to keep crops healthy. Increasingly, organic pesticides are sought as an alternative. Some organic pesticides contain live spores of the fungus Trichoderma to suppress other pathogens. Researchers at Göttingen University found one Trichoderma species can cause severe rot in cobs of maize (corn). Results were published in Frontiers in Agronomy. (2020-09-30)

Redefining drought in the US corn belt
