Legume plants form nitrogen-fixing nodules on their roots in symbiosis with soil bacteria rhizobia. The number of symbiotic is controlled by a host plant via systemic mechanism known as autoregulation nodulation (AON). key players AON are the CLE peptides which produced root response to rhizobia inoculation and transported xylem shoot. In shoot, recognized CLV1-like receptor kinase, results sub...

Polar auxin transport is dependent on the family of PIN-formed proteins (PINs), which are membrane transporters of anionic indole-3-acetic acid (IAA(-)). It is assumed that polar auxin transport may be essential in the development and meristematic activity maintenance of Medicago truncatula (M. truncatula) root nodules. However, little is known about the involvement of specific PIN proteins in ...

Asian soybean rust (ASR) caused by Phakopsora pachyrhizi is a devastating foliar disease affecting soybean production worldwide. Understanding nonhost resistance against ASR may provide an avenue to engineer soybean to confer durable resistance against ASR. We characterized a Medicago truncatula-ASR pathosystem to study molecular mechanisms of nonhost resistance. Although urediniospores formed ...

The 14-3-3 gene family, which is conserved in eukaryotes, is involved in protein-protein interactions and mediates signal transduction. However, detailed investigations of the 14-3-3 gene family in Medicago truncatula are largely unknown. In this study, the identification and study of M. truncatula 14-3-3-family genes were performed based on the latest M. truncatula genome. In the M. truncatula...

expressed sequence tags simple sequence repeats (est-ssrs) are important sources for investigation ofgenetic diversity and molecular marker development. similar to genomic ssrs, the est-ssrs are usefulmarkers for many applications in genetics and plant breeding such as genetic diversity analysis, molecularmapping and cross-transferability across related species and genera. in spite of low polym...

During the initial step of the symbiosis between legumes (Fabaceae) and nitrogen-fixing bacteria (rhizobia), the bacterial signal molecule known as the Nod factor (nodulation factor) is recognized by plant LysM motif-containing receptor-like kinases (LysM-RLKs). The fifth chromosome of barrel medic (Medicago truncatula Gaertn.) contains a cluster of paralogous LysM-RLK genes, one of which is kn...
