One cause of the yield advantage in the 'three sisters' polyculture is that the crops have different, possibly complementary, root foraging strategies.

Ureide accumulation and drought inhibition of N2fixation
A study of common bean genotypes, with variable degrees of N2-fixation tolerance to water stress, finds variable accumulation of ureides in their leaves.
Basal root whorl number and P acquisition
BRWN is associated with increased phosphorus acquisition and this may have value for selection of genotypes with better performance in low-phosphorus soils.
Origins of determinate growth habit in Phaseolus
One of the traits that appeared during domestication of common bean, Phaseolus vulgaris, is determinacy, in which stems end with a terminal inflorescence. Kwak et al. examine sequence variation in PvTFL1y, the gene that...
