Abiotic stress, characterized by salt, drought, high temperatures, and deficits in soil nutrients, is a major obstruction to crop growth and yield globally. Brassica oleracea var. botrytis, commonly known as cauliflower, is a valuable vegetable crop that is particularly vulnerable to these environmental stressors, significantly impacting its yield and quality. This study examines methods to increase B. oleracea var. botrytis resilience and focuses at the mechanisms underlying its resistance to abiotic stress. Crucial physiological functions like osmotic control, elevated antioxidant activity, and the synthesis of stress-responsive genes are necessary for the plant to adapt to stressful conditions. Furthermore, the production of more stress-tolerant cauliflower types can be fostered by knowledge of the genetic basis of stress resistance as well as breeding strategies like marker-assisted selection. The goal of this study is to find key pathways and indicators for improving cauliflower’s resistance to abiotic stress by using experimental techniques including optimized stress environments and molecular investigations. The outcomes of this research may provide significant knowledge to combat abiotic stressors, promoting consistent growth and food security in the context of changing climate conditions.
