The cell replicates itself in an organized, step-by-step fashion known as the cell cycle. Microbial infection invokes multiple layers of host immune responses, and plant gene expression is swiftly and precisely reprogramed at both the transcriptional level and post-transcriptional level. MicroRNAs (miRNAs), a class of endogenous 21–24 nucleotide (nt), single-stranded, non-coding RNAs, modulate the gene expression at the transcription and post-transcriptional levels , .In plants, emerging data demonstrate that miRNAs play vital regulatory roles in a wide range of biological processes, including regulation of plant growth, … Accumulating evidence suggests that a gene regulatory network consisting of these transcription factors has an important role for their dynamic and robust responses. The growth and development of rice roots are controlled by both genetic factors and environmental cues. -A plant adds new organic molecules to its early plants by carbon and you get carbon by photosynthesis -All the plant growth in the embryo before photosynthesizing is dependent on the nutrients stored in the endosperm and the continued uptake of water allows that cell elongation. Development includes growth (cell division, enlargement and differentiation), morphogenesis, maturation and senescence. Overexpression of OsEXPA8 in rice plants … Plant development is different from animals by many fundamental aspects; as they have immobilized cells, a rigid cell wall, and the large central vacuole. Regulation of plant development by maintaining optimal levels of GAs. Request PDF | Genetic and hormonal regulation of cambial development | The stems and roots of most dicot plants increase in diameter by radial growth, … In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Because of its particularly high levels of expression during seed development, bZIP53 could be expected to participate in seed gene regulation. Chromatin Remodeling in Cell Differentiation, Organ Initiation and Development functions required for plant growth. AtCTL1 in now thought to play a role in creating an endogenous signal that is important for the regulation of normal plant growth and development. The past decade has witnessed significant progress in understanding and advances on GRAS transcription factors in various plants. Biochemical, genetic, and genomic approaches have led to the identification of the majority of the genes that encode GA biosynthesis and deactivation enzymes. Numerous studies have been conducted to decipher the genetic and molecular mechanisms of plant drought stress tolerance [76,77]. Understanding the epigenetic regulatory machinery of plants has come, in large part, from genetic screens, most notably in Arabidopsis thaliana, a member of the mustard family that is highly amenable to genetic analyses and was the first plant species to have its genome sequenced. The plant hormone group, the cytokinins, regulates many stages of plant growth and development. Development pathways are controlled by networks of interacting genes 4. Sunflower (Helianthus annuus) seedlings exposed to 20 μT vertical MF showed small, but significant increases in total fresh weights, shoot fresh weights, and root fresh weights, whereas dry weights and germination rates remained unaffected (Fischer et al., 2004).Pea (Pisum sativum) epicotyls were longer in low MF (11.2 ± 4.2 mm, n = … Just as two plants – even if genetically identical – do not look the same, two leaves on the same plant are different, and the final shape of a leaf is not predetermined when it starts to form. Expression of genes that encode transcription factors determine cell, tissue, and organ identity. Development is regulated by cell-to-cell signaling. Plants have evolved variable phenotypic plasticity to counteract different pathogens and pests during immobile life. The metabolome is the final product of genetic and developmental control and environmental interactions, and as such provides a blueprint for plant growth and performance ( Fig. Genetic regulation of sporopollenin synthesis and pollen exine development. The auxin and cytokinin ratio regulates morphogenesis and callus formation under in vitro conditions. The repressive effects of ABA are overcome by GAs, a class of phytohormones that has long held a prominent role in plant growth and development. Much progress has also been made with radial symmetry of flowers, with floral size regulation, and with the later stages of organ development, leading in total to a detailed but partial understanding of the gene regulatory networks and their downstream genes that create plant form throughout the plant life cycle. Lalit M. Srivastava, in Plant Growth and Development: Hormones and Environment, 2002 Plant hormones are small, simple molecules of diverse chemical composition: indole compounds, terpenes, adenine derivatives, steroids, aliphatic hydrocarbons, and derivatives of carotenoids or fatty acids. 16] We shall focus on the types of grwith seen in plants: Primary and Secondary Growth: The mitotic divisions in meristematic cells at the root and shoot apex hikes the length of the plant. B-box (BBX) proteins play important roles in plant growth regulation and development including photomorphogenesis, photoperiodic regulation of flowering, and responses to biotic and abiotic stresses. expansins are involved in mediating the growth of whole plants, plant organs, or plant cells.
