In this article we will discuss about the physiological significances of tuber and bulb formation in plants. The formation of tubers as the stem and bulb swellings of leaf base is governed mostly by the mobilization activities resulting in the storage of carbohydrates and fats thereby degrading the polarity in such organs. Most of the induction for mobilization starts in [...]
In this article we will discuss about the physiology of adventitious root formation. The process of development of adventitious roots in stem cuttings can be divided in three stages: the initiation of group of meristematic cells i.e. root initials; the differentiation of these initials into root primordia and the development and emergence of new roots including stem rupturing, formation of [...]
In this article we will discuss about the role of dark-fixation of CO2 in plants. In several plants a highly specialized cellular adaptation in most of the developmental systems exists in which dark-fixation of CO2 utilizes phosphoenolpyruvate (PEP) derived from carbohydrates as a substrate plays a vital role (Fig). Malate produced from dark fixation of CO2 acted as an osmoregulatory [...]
