Abstract Salt is a major abiotic factor significantly affecting plant growth and development. Alfalfa ( Medicago sativa L.), crucial perennial crop for livestock feed, shows significant differences in salt tolerance among different varieties. This study aimed to comprehensively evaluate the of 30 varieties alfalfa under stress (0, 150, 300 mmol L −1 NaCl). It showed that shoot height (SH), root length (RL), fresh weight (SFW), (RFW) were decreased by 37.68%, 35.83%, 43.79% 48.86%, respectively, high stress. Photosynthesis‐related parameters, including chlorophyll (Chl ), b total (TChl), carotenoids (Car) contents all 50.13%, 43.73%, 48.17% 60.86%, minimum inhibition photosynthetic pigment was observed variety Salsa. The changes antioxidant enzymes also found For example, APX Sardi 7 641.84%, while Phabulous 88.33% compared non‐treated controls. Principal component analysis (PCA) identified five variables: Car, TChl, APX, Chl , POD. Finally, each variety's comprehensive membership function values calculated method, classified into four categories cluster analysis. Our findings indicate 7, Salsa, Gannong No.8, Daye, Instinct are salt‐tolerant provided baseline information on response salinity levels, which will help select or breed

PGPR-Mediated Defense Priming: A Sustainable Paradigm for Combating Biotic and Abiotic Stresses in Agriculture

Open Access Journal of Microbiology & Biotechnology, Journal Year: 2024, Volume and Issue: 9(2), P. 1 - 9

Published: April 2, 2024

In the face of complex biotic and abiotic stresses, modern agriculture seeks innovative solutions to ensure sustainable crop production. Plant Growth-Promoting Rhizobacteria (PGPR) emerges as powerful allies, offering a approach fortifying plant defense mechanisms. This review delves into harnessing PGPR-mediated priming combat both stresses in agriculture. Defense priming, sophisticated mechanism acquired through exposure primary stimuli, empowers plants mount quicker more resilient responses against subsequent challenges. PGPR induce pre-conditioned state heightened alertness, enabling rapid robust upon stress encounters. paradigm not only enhances resilience pathogens environmental stressors but also promotes practices by reducing chemical inputs. The critically evaluates mechanisms underlying emphasizing its potential modulate physiology, metabolite production, increased antioxidants enzymes, related enzymes activities enhance tolerance. It further explores how can improve spectrum stressors. highlights cost-effective, enduring, chemical-free, method for managing Implementing this strategy offers effective protection with minimal fitness costs, even harsh conditions.

Abstract Plants encounter numerous biotic and abiotic challenges, with stresses significantly limiting wheat productivity. Competition for nutrients space among plants adds another layer of stress. Defense priming is a promising approach to enhancing plant protection against these environmental stresses. This study explores BABA (β-aminobutyric acid) in Bipolaris sorokiniana under varying degrees competition. We assessed growth parameters, disease phenotype, biochemical changes, yield-related traits both primed non-primed pressure Our findings revealed that parameters declined as competition increased. However, showed better morphological than at each level. Under pressure, demonstrated comparable non-challenged all levels, while were susceptible. Non-primed high-density (HD) conditions exhibited the highest susceptibility due intense BABA-primed level compared plants. allowed mitigate effects maintain consistent defense response. The yield performance was superior across levels. research suggests an effective pesticide-free strategy crop pathogens competitive conditions.
