Maize production and productivity are affected by drought stress in tropical and subtropical ecologies, as the majority of the area under maize cultivation in these ecologies is rain-fed. The present investigation was conducted to study the physiological and biochemical effects of 24-Epibrassinolide (EBR) as a plant hormone on drought tolerance in maize. Two maize hybrids, Vivek hybrid 9 and Bio 9637, were grown under three different conditions: (i) irrigated, (ii) drought, and (iii) drought+EBR.

In recent times, linseed has emerged as a superfood due to its high content of health-promoting omega-3 fatty acids and other bioactive compounds. Among primary health effects, it has potential to manage hypertension, diabetes, osteoporosis, atherosclerosis, cancer, arthritis, neurological, cardiovascular diseases including blood cholesterol levels, constipation, diarrhea, and autoimmune disorders etc.

- Maize, a critical global crop, uses complex gene regulation mechanisms to adapt to drought stress, with the HKI 335 inbred line showing notable resilience.
- Reactive oxygen species (ROS) produced during drought can cause cellular damage, but the enzyme superoxide dismutase (SOD) plays a key role in defending against this damage.
- Detailed analysis of the HKI 335 SOD2 protein revealed its similarity to a known thermostable SOD, with favorable structural properties and a low instability index, indicating its potential effectiveness in stress tolerance.
Article Synopsis
- Conventional agriculture relies on chemical fertilizers, particularly phosphatic fertilizers, to increase crop production, but phosphorus-use efficiency (PUE) is less than 30% for key cereals like maize, leading to significant environmental loss.
- Rock phosphate reserves are limited and may deplete soon, raising concerns about food security and the sustainability of modern farming practices due to heavy reliance on these fertilizers.
- Strategies for enhancing PUE, such as genetic modifications to develop maize cultivars better adapted to phosphate deficiency, show promise and involve exploring root architecture diversity, signaling pathways, and key candidate genes in maize research.
Unlabelled: The post green revolution agriculture is based on generous application of fertilizers and high-yielding genotypes that are suited for such high input regimes. Cereals, like maize ( L.) are capable of utilizing less than 20% of the applied inorganic phosphate (Pi) - a non-renewable fertilizer resource.
