Comparative phylotranscriptomics reveals ancestral and derived root nodule symbiosis programs
There 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…
