Mutation and recombination frequencies reveal a biological contrast within strains of Cucumber mosaic virus.

Unlabelled: Recent in planta studies have shown that strains Fny and LS of Cucumber mosaic virus (CMV) display differential genetic diversities, Fny and LS having higher and lower mutation frequencies, respectively (J. S. Pita and M.

A putative transporter is essential for integrating nutrient and hormone signaling with lateral root growth and nodule development in Medicago truncatula.

Legume root architecture involves not only elaboration of the root system by the formation of lateral roots but also the formation of symbiotic root nodules in association with nitrogen-fixing soil rhizobia. The Medicago truncatula LATD/NIP gene plays an essential role in the development of both primary and lateral roots as well as nodule development. We have cloned the LATD/NIP gene and show that it encodes a member of the NRT1(PTR) transporter family.
