Pure Organic Active Compounds Against Abiotic Stress: A Biostimulant Overview

Frontiers in Plant Science, Journal Year: 2020, Volume and Issue: 11

Published: Dec. 23, 2020

Biostimulants (BSs) are probably one of the most promising alternatives nowadays to cope with yield losses caused by plant stress, which intensified climate change. comprise many different compounds positive effects on plants, excluding pesticides and chemical fertilisers. Usually mixtures such as lixiviates from proteins or algal extracts have been used, but currently companies interested in more specific that capable increasing tolerance against abiotic stress. Individual application a pure active compound offers researchers opportunity better standarise formulations, learn about defence process itself assist agrochemical industry development new products. This review attempts summarise state art regarding various families organic their mode/mechanism action BSs, how they can help maximise agricultural yields under stress conditions aggravated

Mechanistic insights of plant-microbe interaction towards drought and salinity stress in plants for enhancing the agriculture productivity

Plant Stress, Journal Year: 2022, Volume and Issue: 4, P. 100073 - 100073

Published: March 7, 2022

The agricultural sector is an important part of the Indian economy. challenged by various stresses, leading to huge loss in crop productivity globally and disturbs sustainability. Abiotic stresses (drought salinity) are among foremost ecological factors that hinder globally. Several generate excess amounts reactive oxygen species (ROS) either singly or combination, impaired redox homeostasis, causing oxidative stress thereby affecting physiology plant. It further damages yields, other bio-molecules, hormones concerning development. Therefore, sustainable climate-smart agriculture (CSA) uses plant growth-promoting rhizobacteria (PGPR) essential fulfilling demand. Various microbes (PGPM) have vast metabolic capabilities alleviate adverse effect abiotic stresses. Herein we elaborate plant-microbe interaction on several strategies adopted PGPR cope-up these help sustain its mitigating loss. By highlighting interactions this chapter, provide a roadmap for community use beneficial microorganisms improve productivity. Further, relationship between stress, also described summarizes responses plants molecular biochemical mechanisms mediating drought saline stress.

Biosynthesis and beneficial effects of microbial gibberellins on crops for sustainable agriculture

Journal of Applied Microbiology, Journal Year: 2021, Volume and Issue: 132(3), P. 1597 - 1615

Published: Nov. 1, 2021

Soil microbes promote plant growth through several mechanisms such as secretion of chemical compounds including hormones. Among the phytohormones, auxins, ethylene, cytokinins, abscisic acid and gibberellins are best understood compounds. Gibberellins were first isolated in 1935 from fungus Gibberella fujikuroi synthesized by soil microbes. The effect on development has been studied, biosynthesis pathways, enzymes, genes their regulation. This review revisits history gibberellin research highlighting microbial effects health with an emphasis early discoveries current advances that can find vital applications agricultural practices.
