Making sense of a universe of corn genetics

By | Agriculture, News, Plant Science

Seed banks across the globe store and preserve the genetic diversity of millions of varieties of crops. This massive collection of genetic material ensures crop breeders access to a wealth of genetics with which to breed crops that yield better or resist stress and disease. But, with a world of corn genetics at their disposal, how do plant breeders know which varieties are worth studying and which ones aren’t?

Tweaking carotenoid genes helps tomatoes bring their a-game

By | Agriculture, Fruits and Vegetables, News, Plant Science

The popularity of tomatoes has led to the development of more than 10,000 cultivars of various sizes, shapes, and hues. Interestingly though, there is little genetic diversity among modern tomato varieties. This lack of diversity, coupled with the fact that many traits are controlled by multiple genes, makes improving plant yield and quality a major challenge for tomato breeders. A research team shows that modern gene editing techniques can help tomato breeders introduce diversity and improve the nutrition and environmental impact of tomato crops.

Wheat disease common to South America jumps to Africa

By | Agriculture, News, Plant Health, Plant Science, Policy

A deadly wheat disease common to Asia and South America has been identified in Africa for the first time, raising fears of potential spread to wheat crops across the continent. Researchers say that the fast-acting and devastating fungal disease known as wheat blast was first spotted in Africa in the Zambian rainfed wheat production system in the 2017-2018 crop cycle.

Researchers uncover novel mechanism of weak apical dominance in rice

By | Agriculture, News

Cereal crops exhibit two distinct types of branching which are the important determinants of crop yield. Crops such as maize and sorghum produce only one culm to reduce competition among sinks and increase the productivity of the main culm, thus exhibiting enhanced apical dominance. Rice and wheat produce multiple tillers (a type of branch that is similar in shape and height to the main culm) and exhibit weakened apical dominance.

​​​​Short-term moisture removal can eliminate downy mildew of spinach

By | Agriculture, Fruits and Vegetables, News, Plant Health

Downy mildew is the biggest threat to spinach production around the world. While the pathogen has a short life cycle (approximately a week), it can produce millions of spores during the spinach growing season. Overhead sprinkler irrigation systems and dew formation on cool nights leads to more moisture, which enables these spores to infect the spinach.
