The dynamic change in root growth of plants plays an important role in their adjustment to soil conditions. Depending on the location, nutrients or moisture can be found in higher or lower soil layers. This is why, depending on the situation, a short or a long root is advantageous.
The national wheat improvement program in India has contributed significantly toward achieving food security since the advent of the green revolution in the 1960s. However, for the sustainable wheat production in this era of climate change, high yielding thermo-tolerant varieties with durable disease resistance, and with the capacity to produce more with less of water and fertilizers are urgently needed. Recently, the first study conducted on comprehensive and systematic evaluation of ~22,000 accessions of wheat was published.
Being highly connected to a strong social network has its benefits. Now a new study is showing the same goes for trees, thanks to their underground neighbours. This study is the first to show that the growth of adult trees is linked to their participation in fungal networks living in the forest soil.
Questions about the origin of nature have fascinated humans since the dawn of culture. One phenomenon of particular interest is the high diversity of forests in the tropics, relative to those in the temperate zone. One prominent hypothesis is that the greater stability of tropical forests allows greater prevalence of pests, each of which then can exert greater damage on its favored host tree than in the temperate zone, particularly when the tree species concerned becomes common.
The enzyme Rubisco catalyzes the assimilation of CO2 from the atmosphere into organic matter. This is the central step in photosynthesis that generates sugar molecules for the production of essentially all biomass. Despite its pivotal role, Rubisco works relatively slowly and is easily inhibited by sugar products. By improving the function of Rubisco researchers hope to be able to boost the process of photosynthesis. The goal is to address the growing global demand for food and reduce the current greenhouse gas-induced climate change.
The cultivation of vanilla in Madagascar provides a good income for small-holder farmers, but without trees and bushes the plantations can lack biodiversity. Agricultural ecologists have investigated the interaction between prey and their predators in these cultivated areas.
Known degradation pathways are not involved in chloroplast turnover but are required for damage and starvation responses. Plant cells use an unknown mechanism to mark damaged chloroplasts for destruction, biologists have discovered.
In the face of the Covid-19 pandemic and the mounting threat of climate change, forests and trees are vital for the rural poor in countries around the world. However, the poor are rarely able to capture the bulk of benefits from forests. A global science assessment analyses how forests can realize their potential to reduce poverty in a fair and lasting manner.
For vegetable growers, weeds can mean lost income from reduced yield and foreign plant matter contaminating the harvest. But for many crops, particularly vegetable legumes, weed management options are very limited. A new study shows early-terminated rye could be a promising part of an integrated weed management program for some vegetable legumes, including edamame.
Researchers know how to make precise genetic changes within the genomes of crops, but the transformed cells often refuse to grow into plants. One team has devised a new solution.
