Comparative phylotranscriptomics reveals ancestral and derived root nodule symbiosis programs
Plant Science Research WeeklyThere are about ~17,500 plants species that can participate in nitrogen-fixing root nodule symbioses. The majority of these (~17,300) are in the order Fabales, which includes the legumes. The remainder fall into three orders (Rosales, Fagales, and Cucubitales), leading to the question of whether this…

How do legumes decide where to get nitrogen––from the soil or from nitrogen-fixing bacteria?
The Plant Cell: In a NutshellMisawa, Ito, et al. explore how nitrate transporters and NIN-like protein transcription factors repress nodulation in the presence of exogenous nitrate.
