Phytohormone

Ethylene is an important phytohormone that regulates several aspects of plant development including those crucial for drought tolerance. The main aim of the present work was to investigate variability in ethylene sensitivity of mungbeans to seed germination, waterlogging, and leaf senescence, and the underlying transcriptional regulation of ethylene biosynthetic/responsive genes. Significant variation was observed for silver-nitrate–mediated germination inhibition and flooding stress tolerance among the mungbean genotypes.

Sugar beet is an industrial crop cultivated mostly for sucrose production. Today, modern hybridization applications have raised the sugar content to 20%. Considering the increased demand globally, it is required to develop new yield–increasing application strategies. This requires extensive knowledge of the genetic mechanisms to control plant growth and metabolism. Investigation of phytohormones is promising to increase our knowledge of plant growth and developmental processes. Strigolactones are recently introduced plant hormones.

Fruit ripening is an intricate developmental process driven by a highly coordinated action of complex hormonal networks. Ethylene is considered as the main phytohormone that regulates the ripening of climacteric fruits. Concomitantly, several ethylene-responsive transcription factors (TFs) are pivotal components of the regulatory network underlying fruit ripening. Calmodulin-binding transcription activator (CAMTA) is one such ethylene-induced TF implicated in various stress and plant developmental processes.

Bananas (Musa spp.) are the most important fruit crops worldwide due to their high nutrition value. Fusarium wilt of banana, caused by fungal pathogen Fusarium oxysporum f. sp. cubense tropical race 4 (Foc 4), is considered as the most destructive disease in the world and results in extensive damage leading to productivity loss. The widespread use of plant resistance inducers (PRIs), such as benzothiadiazole (BTH), is a novel strategy to stimulate defense responses in banana plants to protect against pathogens infection.

Cytokinin is a classical phytohormone that plays important roles in numerous plant growth and development processes. In plants, cytokinin signals are transduced by a two-component system, which involves many genes, including cytokinin response factors (CRFs). Although CRFs take vital part in the growth of Arabidopsis thaliana and Solanum lycopersicum, little information of the CRFs in the Brassica U-triangle species has been known yet.

Tartary buckwheat (Fagopyrum tataricum Gaertn.) is a widely cultivated medicinal and edible crop with excellent economic and nutritional value. The development of tartary buckwheat seeds is a very complex process involving many expression-dependent physiological changes and regulation of a large number of genes and phytohormones.

Cotton is the most essential textile crop worldwide, and phytohormones are critical for cotton fiber development. One example is the role of auxin in fiber initiation, but we know little molecular basis. MicroRNAs (miRNAs) have a significant function in cotton development; nevertheless their role in fiber initiation remains unclear.
