Discovering the genetic modules controlling root nodule symbiosis under abiotic stresses: salinity as a case study. [PDF]
New Phytol, 2023 Summary Legumes form a symbiotic association with rhizobia and fix atmospheric nitrogen in specialized root organs known as nodules. It is well known that salt stress inhibits root nodule symbiosis by decreasing rhizobial growth, rhizobial infection, nodule number, and nitrogenase activity in diverse legumes.

Argonaute5 and its associated small RNAs modulate the transcriptional response during the rhizobia-Phaseolus vulgaris symbiosis [PDF]
Frontiers in Plant Science, 2022 Both plant- and rhizobia-derived small RNAs play an essential role in regulating the root nodule symbiosis in legumes. Small RNAs, in association with Argonaute proteins, tune the expression of genes participating in nodule development and rhizobial ...

Journal of Ecology, Volume 111, Issue 6, Page 1218-1230, June 2023., 2023 Our results demonstrate that soil nutrient‐based species selection is a prevalent driver of community assembly in tropical forests, a process mediated by key functional traits within the leaf and wood economics spectrum. Functional space size and its filling increase with soil nutrient concentration, whereas niche vacancy decreases.

Rank‐based data synthesis of common bean on‐farm trials across four Central American countries
Crop Science, Volume 62, Issue 6, Page 2246-2266, November/December 2022., 2022 Abstract Location‐specific information is required to support decision making in crop variety management, especially under increasingly challenging climate conditions. Data synthesis can aggregate data from individual trials to produce information that supports decision making in plant breeding programs, extension services, and of farmers. Data from on‐
