Fall armyworm (Spodoptera frugiperda (J.E. Smith) is a devastating insect, which is known for its polyphagous nature. That is, its ability to feed on various kinds of food sources. This insect can migrate up to 100 km in a single night and therefore, it becomes a devastating pest in many countries that demands proper management. Recent research has develped a new and innovative technique of managing the larvae on maize plants.
An international team of researchers, has successfully unravelled the genomes of 418 unique samples of rapeseed from across the globe to identify traits that breeders can use to improve crop yield.
Hybrid agricultural and horticultural crops can play an important role in supporting global food security. They produce higher yields and are often more resistant than non-hybrid varieties to diseases and climate stress. But for many crops, no hybrid varieties are available. Why is that?
Flowering time in chickpeas’ wild relatives is influenced by one to three major genes, according to new research.
Witchweed is considered by the United Nations to be a major impediment to poverty alleviation in Africa. The parasite attacks major cereal crops such as maize, sorghum, millet, sweetcorn and rice, latching on to their roots and draining the host of moisture and nutrients. Witchweed can lead to significant crop losses and can sometimes wipe out entire harvests. Damage to agriculture in Africa caused by the plant is estimated at approximately US$9 billion a year, with infestations affecting the lives of over 100 million people in 25 countries.
A team of researchers affiliated with a large number of institutions in China and one in Germany has found that turning off a certain gene in corn and rice can lead to improvements in crop yields. In their paper published in the journal Science, the group describes mapping the genomes of both plants as a way to search for genes associated with grain yield using CRISPR gene editing to improve yields in test crops.
A tremendous amount of research has been done to explore Si action in plants against drought, waterlogging, salinity, heavy metals, ultra-violet, as well as pathogenic and entomological attacks. While most studies address Si role in abiotic and biotic stress conditions, one question remains: Can Si be used to improve crop production in the absence of significant stress?
Plant hormones are well known for their important roles in plant development, including fruit development, and many researchers have devoted significant effort towards understanding the relationship between plant hormones and parthenogenesis. What are the latest research advances in hormones and parthenogenesis? What are the molecular mechanisms that underlie parthenocarpic fruit formation, specifically the role of plant hormones? Until recently, a current summary of this information was lacking.
