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:

In the world, pest infestation is responsible for 70% or more of per cent losses in agricultural productivity, and mycopesticide can provide an alternative option to pest control option as an alternative to synthetic pesticides. Trichoderma is a genus of fungal species, and Trichoderma viride is one of the known fungal species in categories that exhibit biocontrol mechanisms since it is well-identified for 100% effectiveness in pest control. The mycelium of T. viride has shown its capabilities for the production of various types of enzymes, including cellulases and chitinase, with degradation
