agricultural-biotechnology
Agricultural biotechnology encompasses the application of scientific tools such as genetic engineering, molecular markers, tissue culture, and molecular diagnostics to modify and improve crop plants. By enabling precise manipulation of plant genomes and traits, it allows researchers to develop crops with enhanced yield, disease resistance, drought tolerance, and nutritional profiles. This field is central to addressing global food security challenges while also serving as a platform for fundamental discoveries in plant biology and genetics.

Scientists have mapped out how plants use nine key chemical messengers — called hormones — to control nearly every stage of life, from sprouting seeds to fighting off disease. This review synthesizes decades of research into a unified framework showing how these hormones work together as a coordinated network.
Nine distinct plant hormones — including abscisic acid, auxins, gibberellins, and ethylene — collectively govern virtually all major plant life events from seed dormancy through senescence.
Hormonal pathways interact with each other primarily through two molecular mechanisms: transcriptional regulation (switching genes on/off) and direct protein-protein interactions.
The integrated molecular framework described has direct agricultural applications, offering new strategies to engineer crops resilient to emerging environmental and biological challenges.
