The collaboration revealed that the symbiotic relationship between plants and fungi provides nitrates to plants, which could lead to reduced fertilizer use.
A research group has succeeded in greatly increasing the catalytic activity of Rubisco, the enzyme which fixes carbon from CO2 in plant photosynthesis. The research team also hypothesized the mechanism which determines the catalytic activity of Rubisco, based on structural analysis of the proteins.
Researchers have shed light on the reproductive role of ‘dark matter’ DNA – non-coding DNA sequences that previously seemed to have no function.
Scientists have discovered two proteins in rice involved in pollen aperture formation which are essential in the successful pollination of flowering plants.
A protein hijacked from a bacterial pathogen helps to facilitate more precise genome editing in plants. A new genome editing system enhances the efficiency of an error-free DNA repair pathway, which could help improve agronomic traits in multiple crops.
A new global study reveals the extent to which high-yielding rice varieties favored in the decades since the “Green Revolution” have a propensity to go feral, turning a staple food crop into a weedy scourge.
Many genetic and breeding studies have shown that point mutations and indels (insertions and deletions) can alter elite traits in crop plants. Although nuclease-initiated homology-directed repair (HDR) can generate such changes, it is limited by its low efficiency. Base editors are robust tools for creating base transitions, but not transversions, insertions or deletions. Thus, there is a pressing need for new genome engineering approaches in plants.
A team of researcher examined how 14 rice diverse varieties photosynthesize—the process by which all crops convert sunlight energy into sugars that ultimately become our food. Looking at a little-studied attribute of photosynthesis, they found small differences in photosynthetic efficiency under constant conditions, but a 117 percent difference in fluctuating light, suggesting a new trait for rice breeder selection.
Reading the Basmati Genome Provides Clues for Growing Drought-Tolerant and Bacteria-Resistant Rice. Using an innovative genome sequencing technology, researchers assembled the complete genetic blueprint of two basmati rice varieties, including one that is drought-tolerant and resistant to bacterial disease.
