Special Groups

Plant growth and development are controlled by large regulatory network which modulates activity of special groups of cells — apical meristems. This control is performed by means of phytohormones and transcriptional factors, the regulators of gene expression. In this review principal transcriptional factors regulating plant apical meristems are described, and the data are presented about their interactions with the most important plant hormones, auxins, cytokinins and gibberellins. General tendencies of these interactions are depicted.

Cellular Processes

Plant growth regulators are significant chemical compounds which are synthesized inside the plant cells and play vital role in plant growth and development. Such compounds are usually active at very low concentrations. These plant growth regulators act as a signalling molecule, which influences the growth of plants. Throughout the previous year’s remarkable investigation have been done for understanding the synthesis of auxin and its effect on various physiological progressions. Auxin is a plant hormone that is involved in various physiological activities, including basic cellular processes such as cell enlargement, regulation of the cell cycle and distinction progress. Plants and several other microorganisms together produce auxin in order to carry out their cell cycle. The chemically synthesized auxins like NAA (naphthalene acetic acid) and IBA (Indole- butyric acid), also take part in various cellular processes. Against various types of biotic and abiotic stress conditions, these plant hormones significantly contribute in promoting acclimatization and adaptation in combination with other phytohormones. The present review highlights some of the important features of auxin role in regulation of plant growth either alone or in crosstalk with other plant hormones.

The Third

Hydrogen sulfide (H2S), once recognized only as a poisonous gas, is now considered the third endogenous gaseous transmitter, along with nitric oxide (NO) and carbon monoxide (CO). Multiple lines of emerging evidence suggest that H2S plays positive roles in plant growth and development when at appropriate concentrations, including seed germination, root development, photosynthesis, stomatal movement, and organ abscission under both normal and stress conditions. H2S influences these processes by altering gene expression and enzyme activities, as well as regulating the contents of some secondary metabolites. In its regulatory roles, H2S always interacts with either plant hormones, other gasotransmitters, or ionic signals, such as abscisic acid (ABA), ethylene, auxin, CO, NO, and Ca2+. Remarkably, H2S also contributes to the post-translational modification of proteins to affect protein activities, structures, and sub-cellular localization. Here, we review the functions of H2S at different stages of plant development, focusing on the S-sulfhydration of proteins mediated by H2S and the crosstalk between H2S and other signaling molecules.

Stimulate Plant Growth

The plant hormones auxin, cytokinin and gibberellic acid, which stimulate plant growth and development, induce significant changes in the isoacceptor spectra of various tRNAs. The present experiments revealed that the treatment of wheat seedlings with auxin, cytokinin or gibberellic acid resulted in the appearance of new isoacceptors in the spectra of three tRNA groups specific for amino acids (methionine, tyrosine and valine). These new isoacceptors may be beneficial for the synthesis and regulation of the proteins induced by the plant hormones.

Signal Cascade

Sunlight not only drives photosynthesis, but also provides cues to regulate plant growth and development. Termed photomorphogenesis, this ability to modulate development in response to changes in light is key to plant survival. Plants have evolved several photoreceptors to perceive and respond to different wavelengths of light found in the daylight spectrum. The majority of plant photoreceptors are proteins with a bound chromophore, a non-protein component that captures photon energy from a particular wavelength of light and converts it into a signal by inducing conformational changes in the protein itself. The resulting changes in the protein activate a signal cascade, which in turn produces alterations in gene expression, allowing the plant to adapt to the light environment. This article discusses what is known about a novel plant photoreceptor, UVR8, and the signalling pathway it activates.
