UrduIn the several decades since sea otters began to recolonize their former habitat in Elkhorn Slough, a salt marsh-dominated coastal estuary in central California, remarkable changes have occurred in the landscape.

Protein root discovery seals future of climate proof plants
Researchers have discovered a protein that seals plant roots to regulate the uptake of nutrients and water from the soil, the discovery could help develop climate proof crops that require less water and chemical fertilizers
A Single Gene and a Unique Layer of Regulation Opens the Door for Novel Plant-Fungi Interactions
Plants have a complex layer of regulation that allows beneficial fungi to colonize their roots while protecting them from harmful ones such as pathogens. Researchers recently identified the underlying plant signaling processes within this layer of regulation that permits a specific beneficial bacteria species to colonize the roots of switchgrass.
Hanging by a purple thread
A movement is raising awareness of native gromwell plant’s importance in preserving Japanese culture. For example, revival projects currently underway throughout Japan are investigating the seed’s origins and educating the public on the importance of protecting the plant’s homogeneity. Purple gromwell contains shikonin derivatives in the plant’s root surfaces, which are red naphthoquinones. This natural pigment and medicinal properties are linked to ancient East Asian traditions.
Dual nature of beneficial bacteria
UD1022, a patented beneficial bacteria, can protect alfalfa plants from fungal pathogens that cause plant disease. But plant growth-promoting bacteria like UD1022 can have a dark side and antagonize other beneficial bacteria present in soil.
Research reveals plant roots change shape and branch out for water
Researchers have discovered how plant roots adapt their shape to maximise their uptake of water, pausing branching when they lose contact with water and only resuming once they reconnect with moisture, ensuring they can survive even in the driest conditions.
Colleen Iversen on Belowground Ecology
After working on a climate change experiment that showed plants adapt to additional carbon dioxide by putting extra carbon into their roots, Colleen Iverson has been on a mission to understand the role of roots in the environment, especially the tundra.
