How increasing the yield potential depends on the row-type in barley

By | Agriculture, News, Plant Science

Agriculture is the major player in contributing to global food security. Increasing our crop productivity is currently a challenging task due to the limitations of climatic change and decreasing of agricultural land. Sustainable agriculture has been considered an excellent solution for the prevailing and future environmental conditions. To contribute to sustainable agriculture by improving crop productivity, we need precise information about these crops. Knowledge about the interactions of different yield components is of great importance for the best possible exploitation of yield potential. In barley, it is particularly important to increase the number of grains per spike. However, which factors play a role in this and what differences there are between different barley row-types has hardly been researched so far.

The layered effect: A single-cell map of corn’s root reveals a regulator of cellular diversity

By | Agriculture, News, Plant Science

A new study uses novel single-cell profiling techniques to reveal how plants add new cell layers that help them resist climate stressors like drought or flooding. The research focuses on corn—a critically important crop around the world—in an effort to create a cell-by-cell map of the plant’s root system, which mediates drought stress and absorbs nutrients and fertilizer from the soil.

Bacteria and Plants Fight Alike

By | News, Plant Health, Plant Science

A brown blotch on a plant leaf may be a sign that the plant’s defenses are hard at work: When a plant is infected by a virus, fungus or bacterium, its immune response keeps the disease from spreading by killing the infected cell, as well as a few surrounding ones. A new study points to the evolutionary origins of this plant immune mechanism. The study may help explain how major plant defenses work and how they may one day be strengthened to increase resilience against plant diseases that each year cause billions of dollars of crop losses worldwide.

The protein bHLH11 functions as an active repressor for iron toxicity in Arabidopsis

By | News, Plant Science

Iron (Fe) is an indispensable microelement for plant growth and development, but Fe excess can be toxic to plants. To maintain Fe homeostasis, plants must sense the environmental Fe concentration and fine-tune the expression of Fe uptake-associated genes accordingly. Previous studies have shown that bHLH11 is a negative transcription factor that regulates Fe homeostasis. However, the underlying molecular mechanism remains elusive.
