Transcriptional Regulation of Circadian Rhythm System for Developmental Stages in Cucumis melo L.: A Bioinformatic Study

Abstract

Circadian rhythm is defined biochemical, physiological, metabolic and behavioral responses of all living organisms such as bacteria, mammals, fungi and plants within a 24-hour light and dark photoperiod. In plants, circadian rhythm regulates multiple physiological, metabolic and behavioral processes such as stomatal and leaf movements, stem elongation, enzyme activity and aging. Circadian clock genes are known to play a role in regulating the biosynthesis of phytohormones which are involved in many crucial processes such as seed germination, hypocotyl elongation and photosynthesis. Circadian rhythm regulates and optimizes physiological and molecular mechanisms in a diurnal cycle, anticipating seasonal changes and preparing the plant for different environmental conditions in plant. Circadian rhythm also plays a crucial role in the regulation of plant defense against biotic and abiotic stresses. Melon is a diploid species and one of the most important Cucurbitaceae family members. In this study, we aimed to investigate the relationship between different developmental processes and circadian rhythm in melon. The relationship between circadian rhythm and growth, development and resistance in melon a detailed understanding of the relationship will help to improve future agricultural production and ground for further research on tolerance to environmental stresses will be created.
