Phytochrome A Protects Tomato Plants From Injuries Induced by Continuous Light.

Front Plant Sci 2019 30;10:19. Epub 2019 Jan 30.

Horticulture and Product Physiology, Wageningen University & Research, Wageningen, Netherlands.

Plants perceive and transduce information about light quantity, quality, direction and photoperiod via several photoreceptors and use it to adjust their growth and development. A role for photoreceptors has been hypothesized in the injuries that tomato plants develop when exposed to continuous light as the light spectral distribution influences the injury severity. Up to now, however, only indirect clues suggested that phytochromes (PHY), red/far-red photoreceptors, are involved in the continuous-light-induced injuries in tomato. Read More

Concentration Dependent Effect of Plant Root Exudates on the Chemosensory Systems of KT2440.

Front Microbiol 2019 30;10:78. Epub 2019 Jan 30.

Estación Experimental del Zaidín, Department of Environmental Protection, Consejo Superior de Investigaciones Científicas, Granada, Spain.

Plant root colonization by rhizobacteria can protect plants against pathogens and promote plant growth, and chemotaxis to root exudates was shown to be an essential prerequisite for efficient root colonization. Since many chemoattractants control the transcript levels of their cognate chemoreceptor genes, we have studied here the transcript levels of the 27 KT2440 chemoreceptor genes in the presence of different maize root exudate (MRE) concentrations. Transcript levels were increased for 10 chemoreceptor genes at low MRE concentrations, whereas almost all receptor genes showed lower transcript levels at high MRE concentrations. Read More

Isoprene Acts as a Signaling Molecule in Gene Networks Important for Stress Responses and Plant Growth.

Plant Physiol 2019 Feb 13. Epub 2019 Feb 13.

Michigan State University CITY: East Lansing STATE: Michigan POSTAL_CODE: 48824 United States Of America [US]

Isoprene synthase converts dimethylallyl diphosphate to isoprene and appears to be necessary and sufficient to allow plants to emit isoprene at significant rates. Isoprene can protect plants from abiotic stress but is not produced naturally by all plants; for example, Arabidopsis (Arabidopsis thaliana) and tobacco (Nicotiana tabacum) do not produce isoprene. It is typically present at very low concentrations, suggesting a role as a signaling molecule; however, its exact physiological role and mechanism of action are not fully understood. Read More

ARR22 overexpression can suppress plant Two-Component Regulatory Systems.

PLoS One 2019 11;14(2):e0212056. Epub 2019 Feb 11.

Department of Plant Physiology at the Center for Plant Molecular Biology (ZMBP), University of Tübingen, Tübingen, Germany.

In plants, several developmental processes are co-coordinated by cytokinins via phosphorylation dependent processes of the Two-Component System (TCS). An outstanding challenge is to track phosphorelay flow from cytokinin perception to its molecular outputs, of which gene activation plays a major role. To address this issue, a kinetic-based reporter system was expounded to track TCS phosphorelay activity in vivo that can distinguish between basal and cytokinin dependent effects of overexpressed TCS members.

ABA inhibits root cell elongation through repressing the cytokinin signaling.

Plant Signal Behav 2019 Feb 9:1-3. Epub 2019 Feb 9.

a Graduate School of Science and Technology , Nara Institute of Science and Technology , Ikoma , Nara , Japan.

Cell elongation, which plays an important role in root penetration into the soil, responds to a variety of environmental factors. A previous study demonstrated that abscisic acid, a phytohormone involved in stress responses, inhibits root growth by delaying the onset of cell elongation. In contrast, we recently reported that cytokinins promote elongation of root cells by enhancing actin bundling. Read More

Diverse role of γ-aminobutyric acid in dynamic plant cell responses.

Plant Cell Rep 2019 Feb 9. Epub 2019 Feb 9.

Bashkir Research Institute of Agriculture, Russian Academy of Sciences, Ufa, Russia.

Gamma-aminobutyric acid (GABA), a four-carbon non-protein amino acid, is found in most prokaryotic and eukaryotic organisms. Although, ample research into GABA has occurred in mammals as it is a major inhibitory neurotransmitter; in plants, a role for GABA has often been suggested as a metabolite that changes under stress rather than as a signal, as no receptor or motif for GABA binding was identified until recently and many aspects of its biological function (ranging from perception to function) remain to be answered. In this review, flexible properties of GABA in regulation of plant responses to various environmental biotic and abiotic stresses and its integration in plant growth and development either as a metabolite or a signaling molecule are discussed.

Auxins in potato: molecular aspects and emerging roles in tuber formation and stress resistance.

Plant Cell Rep 2019 Feb 9. Epub 2019 Feb 9.

Laboratory of Signaling Systems, Timiryazev Institute of Plant Physiology, Russian Academy of Sciences, Moscow, 127276, Russia.

The study of the effects of auxins on potato tuberization corresponds to one of the oldest experimental systems in plant biology, which has remained relevant for over 70 years. However, only recently, in the postgenomic era, the role of auxin in tuber formation and other vital processes in potatoes has begun to emerge. This review describes the main results obtained over the entire period of auxin-potato research, including the effects of exogenous auxin; the content and dynamics of endogenous auxins; the effects of manipulating endogenous auxin content; the molecular mechanisms of auxin signaling, transport and inactivation; the role and position of auxin among other tuberigenic factors; the effects of auxin on tuber dormancy; the prospects for auxin use in potato biotechnology.

RNA editing is a widespread epitranscriptomic mechanism by which primary RNAs are specifically modified through insertions/deletions or nucleotide substitutions. In plants, RNA editing occurs in organelles (plastids and mitochondria), involves the cytosine to uridine modification (rarely uridine to cytosine) within protein-coding and non-protein-coding regions of RNAs and affects organelle biogenesis, adaptation to environmental changes and signal transduction. High-throughput sequencing technologies have dramatically improved the detection of RNA editing sites at genomic scale. Read More
