Researchers at University of Tsukuba have uncovered a master transcriptional regulator that controls rhizobial symbiosis between plants and nitrogen-fixing bacteria. By identifying an amino acid motif ...

The developmental regulators that confer the identity of N-fixing root nodules belong to a transcription factor family (LSH) more commonly associated with defining the shapes of stems, flowers and ...

WEST LAFAYETTE, Ind. – Plant breeders could theoretically increase soybean crop yields if they could control the number of nodules on plant roots since they are responsible for fixing atmospheric ...

Legume root nodules originate from differentiated cortical cells that reenter the cell cycle and form organ primordia. We show that perception of the phytohormone cytokinin is a key element in this ...

Comparative phenotypic analysis of pea (Pisum sativum) sym35 mutants and Lotus japonicus nin mutants suggested a similar function for the PsSym35 and LjNin genes in early stages of root nodule ...

Most scientific research on the root-soil interactions of legumes focuses on rhizobia and nitrogen-fixing root nodules. However, many forms of non-rhizobia bacteria are also detected in these nodules.

THE red pigment in the root nodules of a leguminous plant (Vicia Faba) was investigated for the first time by Pietz 1. He believed it to be identical with the red intermediate product which appears ...

Cambridge scientists have identified two crucial genetic factors needed to produce specialised root organs that can accommodate nitrogen-fixing bacteria in legumes such as peas and beans. In a ...
