Translational regulation of gene expression in plants
Current Opinion in Biotechnology, 1997Translational regulation plays a major role in plant gene expression. Recent advances have been made in understanding how this mechanism of control is directed in the chloroplast as well as in the cytoplasm. Our knowledge of translational regulation in plant mitochondria, however, is limited.

Epigenetic control of gene regulation in plants
Biochimica et Biophysica Acta (BBA) - Gene Regulatory Mechanisms, 2011In eukaryotes, including plants, the genome is compacted into chromatin, which forms a physical barrier for gene transcription. Therefore, mechanisms that alter chromatin structure play an essential role in gene regulation. When changes in the chromatin states are inherited trough mitotic or meiotic cell division, the mechanisms responsible for these ...

Plant Gene Expression, Regulation of
2006Eukaryotic genomes are much more complex than prokaryotes and plant genomes present more complexities than other eukaryotes. The continuous process of development, absence of germ-line, flexible and reversible cellular differentiation, polyploidy, and so on, are characteristic features that distinguish plant genomes from other eukaryotes.

MicroRNA regulation of gene expression in plants
Current Opinion in Plant Biology, 2004It has only been a few years since we began to appreciate that microRNAs provide an unanticipated level of gene regulation in both plants and metazoans. The high level of complementarity between plant microRNAs and their target mRNAs has allowed rapid progress towards the elucidation of their varied biological functions.

Chemically regulated gene expression in plants
Current Opinion in Plant Biology, 2003Chemically inducible systems that activate or inactivate gene expression have many potential applications in the determination of gene function and in plant biotechnology. The precise timing and control of gene expression are important aspects of chemically inducible systems. Several systems have been developed and used to analyze gene function, marker-

Regulation of plant gene expression
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1986Differential gene expression is required to establish and maintain specific developmental states in higher plants. For example, an anther has at least 11000 diverse mRNAs that are absent from the polysomes of other organ systems, and the root has at least 7000 organ-specific mRNAs.

Auxin-Regulated Gene Expression in Plants
1989Publisher Summary This chapter discusses auxin-regulated gene expression in plants. There are five main types of plant hormones: auxins, cytokinins, gibberellins, abscisic acid, and ethylene. The classic effect of auxins, typified by indole acetic acid (IAA), is the regulation of plant cell growth, a process that requires extension of the cell wall ...

Plant RNA Polymerases: Structures, Regulation, and Genes
1987Plants, like other eukaryotes, have three distinct classes of nuclear DNA-dependent RNA polymerases (9,10,21,26). In addition, they possess RNA polymerases unique to the chloroplast and mitochondrial organelles. Within the nucleus, genomic DNA is transcribed by RNA polymerases I (or A), II (or B), and III (or C), and each class of enzyme carries out a ...

Sugar regulation of gene expression in plants
Current Opinion in Plant Biology, 1998The molecular details of sugar sensing and sugar-mediated signal transduction pathways are unclear but recent results suggest that hexokinase functions as an important plant sugar sensor in a way that is similar to that found in yeast. The use of mutants in Arabidopsis defective in specific signaling steps is of particular importance because these give

Alternative polyadenylation and gene expression regulation in plants
WIREs RNA, 2010AbstractFunctioning as an essential step of pre‐mRNA processing, polyadenylation has been realized in recent years to play an important regulatory role during eukaryotic gene expression. Such regulation occurs mostly through the use of alternative polyadenylation (APA) sites and generates different transcripts with altered coding capacity for proteins ...
