Tree roots commonly associate with fungi to exchange nutrients and improve their adaptation to changes in their environment. However, the biological processes at work in this mutually beneficial relationship (namely ectomycorrhizae) have not yet been fully explored. Now, researcher have demonstrated for the first time that the establishment of the symbiotic relationship between the model tree poplar and an ectomycorrhizal fungus is controlled by epigenetics.
Can the deathbed rally of a few dying cells save the rest of the body? New evidence from plants. The “deathbed rally,” the “last hurrah” — it’s not unheard of for living things to mysteriously perk up in the moments before death. It turns out that plants do it too, at least at the cellular level.
Researchers ahave recently discovered a new species of Fabaceae. The new species was named Astragalus bashanense.
The tropics hold most of the planet’s biodiversity. In order to preserve this fragile and valuable asset, many individuals and communities need to get involved and be well informed. However, tropical ecology and conservation sciences are still often affected by colonialistic and discriminatory practices, which can hamper nature conservation success. An international research team from leading universities in tropical research has now proposed how researchers from the Global South, which consists of nations historically damaged by colonialism, could better promote solutions for a sustainable development.
Most people own houseplants and eagerly grow them on windowsills and shelves only to be disappointed when they wilt or die – new research has shown that the problem could be that we’re feeding them all wrong and we need to pay attention to the roots outside the soil.
High-order chromatin structure is a prerequisite for the function of cis-regulatory elements in the genome, which plays an important role in gene regulation. In eukaryotes, the organization of three-dimensional (3D) genome presents a hierarchical pattern, where chromatin can be divided into different structural domains, such as chromosome territory, A/B compartment, topologically associated domain (TAD) and chromatin loop.
Cassava is one of the most important crops in the tropics, feeding half a billion people in more than 80 countries. Cassava bacterial blight (CBB) is a devastating disease that causes crop losses worldwide. Research demonstrated that a new technology, epigenome editing, can reduce CBB symptoms in cassava plants while maintaining normal growth and development.
Delving deeper into organ development requires long-term monitoring of organ growth. Researchers have designed a novel approach that they employed to characterise growing leaves. Over several weeks scientists photographed more than 1,000 leaves at varying developmental stages. By applying targeted algorithms, they were able to reconstruct the complete story of leaf development.
Using commercial, high-resolution satellite images and artificial intelligence, an international team mapped almost 10 billion individual trees in Africa’s drylands to assess the amount of carbon stored outside of the continent’s dense tropical forests. The result is the first comprehensive estimate of tree carbon density in the Saharan, Sahel, and Sudanian zones of Africa. The data are free and publicly available.
How do plants defend themselves against pathogenic micro-organisms? This is a complex puzzle, of which a team of biologists has solved a new piece. They discovered that while the water pores (hydathodes) in leaves provide an entry point for bacteria, they are also an active part of the defence against these invaders.
