We determined the binding motif of maize ANT1 (ZmANT1), showing that ZmANT1 binds promoters of millet SCR1 , GNC , and AN3 , key regulators of Kranz anatomy, chloroplast development, and plant growth, respectively. OsLMS shares a moderate amino-acid similarity to the Arabidopsis FIERY2/CPL1 gene, which is known to control many plant processes such as stress response and development. This regulation is provided by the integration of external effect, as well as internal signals, such as a level of phytohormones and secondary messengers. the developmental product of a single zygote, consists of genetically identical and semi-autonomous construction units (ramets; Tuomi and Vuorisalo, 1989; Eriksson and Jerling, 1990). Polycomb repressive complexes (PRCs) play crucial roles in transcriptional repression and developmental regulation in both plants and animals. Altering the microbiome by inoculation with a consortium of plant growth-promoting rhizobacteria (PGPR) can enhance plant development and mitigate against pathogens as well as abiotic stresses. Plant-associated microbiomes can boost plant growth or control pathogens. The complexity of the auxin response is illustrated by the recent finding that the auxin-responsive gene set differs significantly between different cell types in the root. Clonality is a widespread characteristic of herbaceous plants. 2011 Apr;7(4):e1002046. Molecular mechanisms involved in establishing the repression state of seed developmental genes, however, are still poorly known. Cell cycle regulation is of pivotal importance for plant growth and development. I-phase represents interphase. Photoautotrophic nutrition All green plants, certain protists ( Euglena viridis) and some bacterial ( green sulphur bacterium, chlorobium) take carbon dioxide and water from the environment and transform these into glucose and oxygen with the help of Sun’s energy trapped by chlorophyll. Root hairs are tubular, cellular outgrowths of epidermal cells that extend from the root surface into the soil. Molecular Basis of Inheritance ( All ) Select Topic. Phylogenetic niche conservatism and plant diversification in South American … We identify genomic regions controlling plant growth and filter a novel transcriptomic data set using network … Here we report the isolation a … Auxin responses are highly context dependent and can involve changes in cell division, cell expansion, and cell fate. 654 Theor Appl Genet (2016) 129:653–673 1 3 Crop production has been largely affected by environ-mental factors that affect all the processes from metabolism to gene expression during plant growth and development. 2017 Jan 25;13(1):e1006574. Role of ubiquitin in the control of plant growth and stress tolerance Vicente Rubio 9. This prevents plants from reaching their maximum genetic potential for growth, development and reproduction. Interphase is called resting stage, but it is in fact a period of great activity. Erratum in PLoS Genet. In recent decades, the frequency of flooding is increasing with the change of global climate. Author summary We estimate the developmental dynamics of plant growth using mathematical functions to fit continuous functions to discrete plant height data collected throughout growth, and we use the parameters defining these mathematical functions as data. All organisms reach a certain stage of growth and maturity in their life before they can reproduce sexually. Abstract.
