Soil salinization is a severe abiotic stress that negatively affects plant growth and development, leading to physiological abnormalities ultimately threatening global food security. The condition arises from excessive salt accumulation in the soil, primarily due anthropogenic activities such as irrigation, improper land uses, overfertilization. presence of Na⁺, Cl-, other related ions soil above normal levels can disrupt cellular functions lead alterations essential metabolic processes seed germination photosynthesis, causing damage tissues even death worst circumstances. To counteract effects stress, plants have developed various mechanisms, including modulating ion homeostasis, compartmentalization export, biosynthesis osmoprotectants. Recent advances genomic proteomic technologies enabled identification genes proteins involved salt-tolerance mechanisms. This review provides short overview impact salinity on underlying mechanisms salt-stress tolerance, particularly salt-stress-responsive associated with these aims at summarizing recent our understanding tolerance providing key background knowledge for improving crops' which could contribute yield quality enhancement major crops grown under saline conditions or arid semiarid regions world.

PLaBAse: A comprehensive web resource for analyzing the plant growth-promoting potential of plant-associated bacteria

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2021, Номер unknown

Опубликована: Дек. 15, 2021

ABSTRACT Plant-beneficial microorganisms are gaining importance for sustainable plant production and phytosanitary practices. Yet there is a lack of computational approaches targeting bacterial traits associated with growth-promotion (PGP), which hinders the in-silico identification, comparison, selection phytostimulatory strains. To address this problem, we have developed new web resource PLaBAse (v1.01, http://plabase.informatik.uni-tuebingen.de/pb/plabase.php ), provides number services, including (i) database screening 5,565 plant-associated bacteria (PLaBA-db), (ii) tool predicting growth-promoting (PGPTs) single genomes (PGPT-Pred), (iii) prediction plant-association by marker gene identification (PIFAR-Pred). The latter was Martínez-García et al. now hosted at University Tuebingen. PGPT-Pred based on our PGPT ontology, literature- OMICs-curated, comprehensive, hierarchical collection ∼6,900 PGPTs that 6,965,955 protein sequences. study distribution across different environments, applied it to 70,540 strains seven environments (including plants), five spheres (organs), two bacteria-induced phenotypes. This analysis revealed plant-symbiotic generally larger genome size higher count PGPT-annotated encoding genes. Obviously, not all reported restricted -or only enriched in-plant-associated symbiotic bacteria. Some also occur in human- animal-associated bacteria, perhaps due transmission PGP (PGPBs) between or because some functions involved adaption processes various environments. Here provide an easy-to-use approach phyla isolation sites, using PLaBA-db, standardized annotation, PGPT-Pred. We believe will improve understanding about entire facilitate PGPB as bio-inoculants biosafety strategies, so help establish targeted bacteria-incorporated systems future.
