A stage-dependent seed defense response to explain efficient seed transmission of Xanthomonas citri pv. fuscans to common bean.

Although seed represents an important means of plant pathogen dispersion, the seed-pathogen dialogue remains largely unexplored. A multiomic approach was performed at different seed developmental stages of common bean (Phaseolus vulgaris L.) during asymptomatic colonization by Xanthomonas citri pv.

The Nitrate Transporter MtNPF6.8 Is a Master Sensor of Nitrate Signal in the Primary Root Tip of .

Nitrate is not only an essential nutrient for plants, but also a signal involved in plant development. We have previously shown in the model legume , that the nitrate signal, which restricts primary root growth, is mediated by MtNPF6.8, a nitrate transporter.

Linking Autophagy to Abiotic and Biotic Stress Responses.

Autophagy is a process in which cellular components are delivered to lytic vacuoles to be recycled and has been demonstrated to promote abiotic/biotic stress tolerance. Here, we review how the responses triggered by stress conditions can affect autophagy and its signaling pathways. Besides the role of SNF-related kinase 1 (SnRK1) and TOR kinases in the regulation of autophagy, abscisic acid (ABA) and its signaling kinase SnRK2 have emerged as key players in the induction of autophagy under stress conditions.

Sweet Immunity: Inulin Boosts Resistance of Lettuce () against Grey Mold () in an Ethylene-Dependent Manner.

The concept of "Sweet Immunity" postulates that sugar metabolism and signaling influence plant immune networks. In this study, we tested the potential of commercially available inulin-type fructans to limit disease symptoms caused by in lettuce. Spraying mature lettuce leaves, with inulin-type fructans derived from burdock or chicory was as effective in reducing grey mold disease symptoms caused by as spraying with oligogalacturonides (OGs).
