A naturally optimized mass transfer process: The stomatal transpiration of plant leaves.

J Plant Physiol 2019 Mar - Apr;234-235:138-144. Epub 2019 Feb 15.

Department of Thermal Science and Energy Engineering, University of Science and Technology of China, Hefei, 230027, People's Republic of China. Electronic address:

Stomatal transpiration of leaves is a dominant pathway of plant physiological water loss. The leaf transpiration rate when stomata are fully open is commonly at the same level as the evaporation rate of a wet surface of the same area as that of the leaf area, although the cumulative area of the stomatal pores is typically less than 3% of the leaf area. To elucidate the highly efficient diffusion of the stomatal array from the perspective of mass transfer theory, stomatal distribution characteristics of various kinds of leaves were obtained with optical microscope, and steady diffusions of water vapor from isolated zero-depth circular stomata, elliptical stomata, and distributed stomatal arrays without airflow parallel to the surface were simulated with the finite element method.

Identification of microRNAs and their targets responding to low-potassium stress in two barley genotypes differing in low-K tolerance.

J Plant Physiol 2019 Mar - Apr;234-235:44-53. Epub 2019 Jan 16.

Department of Agronomy, College of Agriculture and Biotechnology, Zhejiang University, Hangzhou, 310058, China. Electronic address:

MicroRNAs (miRNAs) have diverse and crucial roles in plant growth and development, including in the response to abiotic stresses. Although plant responses to K deficiency are well documented at the physiological and transcriptional levels, the miRNA-mediated post-transcriptional pathways are still not clearly elucidated. In this study, high-throughput sequencing and degradome analysis were performed using two barley genotypes differing in low-K tolerance (XZ149, tolerant and ZD9, sensitive), to determine the genotypic difference in miRNAs profiling.

ABA promotes starch synthesis and storage metabolism in dormant grapevine buds.

J Plant Physiol 2019 Mar - Apr;234-235:1-8. Epub 2019 Jan 4.

Laboratorio de Bioquímica Vegetal, Facultad de Ciencias, Universidad de Chile, Casilla 653, Santiago, Chile. Electronic address:

In grapevine (Vitis vinifera L.) buds, the short day (SD)-photoperiod induces endodormancy and increases the level of ABA and the expression of ABA key biosynthesis genes, which suggests that ABA could be the mediator of the photoperiodic induction of endodormancy. In the present study, it was established that during the development of the endodormancy, the content of ABA and the accumulation of starch increased in parallel in the buds; however, these increases occurred after the buds were already in the state of endodormancy.

Anthocyanin synthesis and light utilisation can be enhanced by reflective mulch - Visualisation of light penetration into a tree canopy.

J Plant Physiol 2019 Feb 21;233:52-57. Epub 2018 Dec 21.

INRES- Horticultural Science - University of Bonn, Auf dem Huegel 6, D-53121 Bonn, Germany. Electronic address:

With the increasing use of hailnets and decrease in light availability in the ripening period of apple fruit, insufficient light exposure often causes poor colouration viz anthocyanin synthesis on certain parts of the fruit and on certain fruit within the tree. The aim of this study was to investigate the potential of improving anthocyanin synthesis, in terms of fruit colouration, the major incentive for a consumer. Therefore, the reflective ground cover Lumilys® was spread between 'Braeburn Mariri Red' apple rows under a crystalline hailnet seven weeks prior to harvest and colour measured on 240 attached apple fruit.

Defoliation and gibberellin synergistically induce tree peony flowering with non-structural carbohydrates as intermedia.

J Plant Physiol 2019 Feb 12;233:31-41. Epub 2018 Dec 12.

Institute of Vegetables and Flowers, Chinese Academy of Agricultural Sciences, Key Laboratory of Biology and Genetic Improvement of Horticultural Crops, Ministry of Agriculture and Rural Affairs, Beijing, China. Electronic address:

Although the natural florescence of the tree peony is short, it can be lengthened by forcing culture. In this study, both defoliation or gibberellic acid (GA) treatment individually induced tree peony (Paeonia suffruticosa 'Luo Yang Hong') flowering under forcing culture, and their combination (D + G) accelerated flowering with a GA-overdose-like phenomenon, indicating that synergism between defoliation and GA treatment may occur. Both defoliation and GA treatment induced a GA response, including (i) increased GA production, (ii) increased PsCPS and PsGA3ox expression, and (iii) decreased PsGA2ox, PsGID1c, and PsGID2 expression; both treatments also positively influenced non-structural carbohydrate (NSC) accumulation.

It is now well documented that plants produce methane (CH) under aerobic conditions. However, the nature of methane production in plants and all the potential precursors and environmental factors that can be involved in the process are not fully understood. Earlier studies have suggested several chemical compounds, including the amino acid methionine, as precursors of aerobic methane in plants, but none have explored other amino acids as potential precursors or blue light as a driving force of methane emission.

Department of Biology, Coastal Carolina University, Conway, SC 29526, USA. Electronic address:

The metalloid element, selenium (Se) is in many ways special and perhaps because of this its research in human and plant systems is of great interest. Despite its non-essentiality, higher plants take it up and metabolize it via sulfur pathways, but higher amounts of Se cause toxic symptoms in plants. However, the molecular mechanisms of selenium phytotoxicity have been only partly revealed; the data obtained so far point out that Se toxicity targets the plant proteome. Read More
