Going back to the future for food crops

By | Agriculture, News

New sensing techniques reveal drought tolerance in ancient wheat and barley relatives, enabling the breeding of resilient crops for a warmer world. This systematic approach uses advanced imaging technologies to identify beneficial traits, paving the way for sustainable agriculture and improved crop yields despite climate change.

Image credit: Nitrogen nutrition and signaling during root nodule symbiosis impact the community assemblies. Lotus plants grown in the presence of inorganic nitrogen secrete specific metabolites and assemble a microbial community with low connectivity. Lotus plants grown in symbiosis-permissive conditions secrete metabolites such as flavonoids (1) that induce Nod factor production in compatible nitrogen-fixing Rhizobiumisolates (2). Nod factors are recognized by the Lotus host which initiates a signaling pathway (3) to accommodate the symbiont. Symbiotically active roots have an exudate profile (4) and associated microbial communities that differ from plants grown in the presence of inorganic nitrogen. It remains to be determined how bacterial communities associated with symbiotically active plants impact the host to promote the symbiotic association and plant growth (5).

A new study reveals key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition

By | Agriculture, News, Plant Science

Researchers found that specific molecules enable symbiotic bacteria to communicate with legume plants, influencing bacterial growth near roots. This signaling fosters beneficial partnerships for nutrient uptake and resilience, crucial for sustainable agriculture. The study highlights the role of plant-bacteria communication in assembling a healthy plant microbiome, enhancing plant nutrition and growth.
