Abstract:
Brassica crops are vital as they supply essential minerals, antioxidants, and bioactive substances like anthocyanins, glucosinolates, and carotenoids. However, biotic and abiotic elements that cause oxidative stress through heavy metals and other eco-toxicants pose a risk to Brassica plants. Increased generation of Reactive Oxygen Species (ROS) causes oxidative stress, which damages biomolecules and interferes with plant growth, productivity, and cellular equilibrium. Plants producing Brassica need an intricate enzyme defence mechanism to fend off oxidative stress. All the enzymes that have be

Abstract:
Productivity of rapeseed (Brassica napus L.), the third most important oilseed crop, was reduced more than other crops under the salt stress higher than the threshold. Thus, breeding, especially at seedling stage, seems necessary. Plants under salt stress, by synthesis of essential metabolites, specific structural proteins or enzymes of metabolic pathways deal with the stress. To identify the molecular mechanisms of salt responsiveness in rapeseed, ‘Option500’ a salt-sensitive genotype was exposed to 0, 150, and 300mM NaCl during the seedling stage.

Abstract:
Crop protection is essential for maintaining and improving agricultural productivity. While pesticides are commonly used to control pests, they pose several challenges, including environmental harm and health risks. Alternative strategies to pesticides include breeding resistant crop varieties, biological control, and utilizing genome-editing tools like CRISPR/Cas. However, the application of epigenome editing, particularly CRISPR activation (CRISPRa), in plants remains underexplored. Phenylalanine ammonia-lyase (PAL), a key enzyme in the phenylpropanoid pathway, plays a pivotal role in plant

Abstract:
Fusarium wilt diseases severely influence the growth and productivity of numerous crop plants. The consortium of antagonistic rhizospheric Bacillus strains and quercetin were evaluated imperatively as a possible remedy to effectively manage the Fusarium wilt disease of tomato plants. The selection of Bacillus strains was made based on in-vitro antagonistic bioassays against Fusarium oxysporum f.sp. lycoprsici (FOL). Quercetin was selected after screening a library of phytochemicals during in-silico molecular docking analysis using tomato LysM receptor kinases “SILKY12” based on its dual role i

Endophytes can confer several beneficial traits to plants, which can contribute to their growth, development, and overall health. They have been found to stimulate plant growth by enhancing nutrient uptake and availability. They can produce plant growth-promoting substances such as auxins, cytokinins, and gibberellins, which regulate various aspects of plant growth and development.

Abstract:
Increased soil salinity is one of the main concerns in agriculture and food production, and it negatively affects plant growth and crop productivity. In order to mitigate the adverse effects of salinity stress, plant biostimulants (PBs) have been indicated as a promising approach. Indeed, these products have a beneficial effect on plants by acting on primary and secondary metabolism and by inducing the accumulation of protective molecules against oxidative stress. In this context, the present work is aimed at comparatively investigating the effects of microbial (i.e., Azospirillum brasilense)

Availability of water is the most important factor for crop productivity. A vast area (more than 50 million hectares) of agricultural land throughout the world suffers from recurring droughts, resulting in poor crop productivity (Carter, 1975). An equally large area of land is affected by high salinity. Even though irrigated agriculture has increased significantly during the past twenty years, the high capital cost of this process and the resulting increase in salinity is making this approach difficult to adopt. Furthermore, excessive irrigation is lowering the water tables, reducing water ava

For many centuries, sesame seeds have been used as a source of oil, protein, vitamins and minerals for human and animal nutrition [4]. Unlike other crops, sesame is considered to be more drought tolerant [5]. However, drought often occurs together with heat or high temperatures and significantly affects sesa-me production.
