Sugar transporters play a crucial role for plant productivity, as they coordinate sugar fluxes from source leaf towards sink organs (seed, fruit, root) and regulate the supply of carbon resources microorganisms rhizosphere (bacteria fungi). Thus, mediated by SUT (sucrose transporters), MST (monosaccharide transporters) SWEET (sugar will eventually be exported families are key determinants crop yield shape microbial communities living in soil. In this work, we performed systematic search...
Nitrogen (N) availability in the forest soil is extremely low and N economy has a special importance woody plants that are able to cope with seasonal periods of growth development over many years. Here we report on analysis amino acid pools expression key genes perennial species Populus trichocarpa during autumn senescence.Amino were measured throughout senescence. Expression arginine synthesis cationic transporter (CAT) senescence was performed. Heterologous yeast mutants performed study...
Dynamic transcriptional regulation is critical for an organism's response to environmental signals and yet remains elusive capture. Such mediated by master transcription factors (TF) that control large gene regulatory networks. Recently, we described a dynamic mode of TF named "hit-and-run". This model proposes can interact transiently with set targets, but the these transient targets continues after dissociation from target promoter. However, experimental evidence validating active...
Invertases are key enzymes for carbon metabolism, cleaving sucrose into energy-rich and signaling metabolites, glucose fructose. play pivotal roles in development stress response, determining yield quality of seed production. In this context, the repertoire invertase gene families is critically scarce legumes. Here, we performed a systematic search 16 Fabaceae genomes. For instance, identified 19 genes model plant Medicago 17 accessions agronomic crop Pisum sativum. Our comprehensive...
Mycorrhizal colonization of plant roots increases the sink strength and creates an additional sugar demand for plant. Nutrient uptake from soil exchanges between fungal partners forming mycorrhizal symbioses present a mean feature among beneficial effects these mutualistic relationships. In associations, in return mineral nutrient provisioning, provides photosynthates to heterotrophic symbiont. This trade is regulated by both transport components, as instance long-distance sucrose leaves...
Abstract Agriculture is particularly impacted by global changes, drought being a main limiting factor of crop production. Here, we focus on pea ( Pisum sativum ), model legume cultivated for its seed nutritional value. A water deficit (WD) was applied during early reproductive phase, harvesting plant organs at two key developmental stages, either the embryonic or seed‐filling stages. We combined phenotypic, physiological and transcriptome analyses to better understand adaptive response...
Transcription factors (TF) are the primary regulators of genome-wide transcriptional changes. With recent release pea genome, a systems analysis TF is now possible in this important legume crop. Here, we used prediction server available at Plant Database to uncover genes Pisum sativum. By means, identified dataset 1807 TFs genome belonging respective families. This was compared with repertoires from model species Medicago truncatula and Arabidopsis thaliana. While higher number could be...
Experimental design. (A) Vector maps of the pBeaconRFP construct containing 35S::GR::bZIP1 [6, 15] and pJD385 empty vector (EV) control a 35S::GR cassette. (B) A 20 minute exposure to 4tU was sufficient detect significant incorporation in RNA fractions Arabidopsis cells, as shown by dot blot imaging 1 μg from 4.5 106 cells exposed 1.5 mM (+) or uracil only (−).
