Forest trees use various strategies to cope with drought stress and these involve complex molecular mechanisms. Pinus halepensis Miller (Aleppo pine) is found throughout the Mediterranean basin one of most drought-tolerant pine species. In order decipher mechanisms that P. uses withstand drought, we performed large-scale physiological transcriptome analyses. We selected a mature tree from semi-arid area suboptimal growth conditions for clonal propagation through cuttings. then used...

Lettuce is an important vegetable in horticulture, but information about the interactive effects of light and temperature on its photosynthetic characteristics was inadequate. This work investigated three temperatures (15/10 (T15), 23/18 (T23), 30/23 °C (T30)) five treatments (100 (P100), 200 (P200), 350 (P350), 500 (P500), 600 μmol·m−2·s−1 (P600)) light–response curves, chlorophyll content, yield lettuce. The results showed that maximum rate, saturation point, lettuce were all highest at...

Acetylcholine (ACh) is believed to improve plant growth. However, regulation at biochemical and molecular levels largely unknown. The present study investigated the impact of exogenously applied ACh (10 µm) on growth chlorophyll metabolism in hydroponically grown Nicotiana benthamiana under salt stress (150 mm NaCl). Salinity reduced root hydraulic conductivity while ACh-treated seedlings exhibited a significant increase, resulting increased relative water content. induced reduction...

Abstract Endoreplication, also known as endoreduplication, is a phyogenetically widespread modified version of the cell cycle in which DNA replication not followed by division. The SIAMESE (SIM) gene Arabidopsis thaliana encodes founding member novel class plant-specific cyclin-dependent kinase (CDK) inhibitors and key regulator endoreplication during development trichomes (shoot epidermal hairs). Here, we have identified mutations CCS52A1 genetic modifiers multicellular trichome phenotype...

Abstract Background Studies on intra-specific variability in leaf functional traits is important to evaluate adaptation of the species predicted climate change, and develop long-term conservation strategy. The main objectives were investigate relationship between leaves C, N, P stoichiometry Chinese fir from different geographical provenances their with environmental factors provenance. Results In this study, we measured 12 36-year-old Cunninghamia lanceolata trees 13 provenances. Analysis...

Abstract Seed development and yield depend on the transport supply of sugar. However, an insufficient nutrients from maternal tissues to embryos results in seed abortion reduction Camellia oleifera. In this study, we systematically examined route regulatory mechanisms sugar import into developing C. oleifera seeds using a combination histological observations, transcriptome profiling, functional analysis. Labelling with tracer carboxyfluorescein revealed symplasmic integument apoplasmic for...

This study sought to investigate the temporal variations in serum calcium concentrations among patients with acute type B aortic dissection (ATBAD) following initial diagnosis, document incidence of severe complications, and evaluate their potential associations. In this retrospective analysis, we examined 42 consecutive diagnosed ATBAD at Zhejiang Hospital between April 2019 2024. Serum-ionized levels were measured admission 24 hours post-admission. Based on changes levels, categorized into...

ABSTRACT CFRD have been widely used worldwide because of their superior structural stability and economy. However, with the increasing dam height, issue deformation control is becoming increasingly prominent, especially panel which closely related to internal rockfill deformation. Comparing monitoring data a single point, slope plane can reflect characteristics area more effective. To ensure long‐term safe operation CFRD, construction analysis particularly important. In order improve...

Light and temperature are two crucial factors affecting plant growth. intensities vary considerably with season weather conditions. Reasonable light regulation at different temperatures is a key issue in environmental regulation. In this study, we determined the effects of intensity on crop growth development. Furthermore, an optimal value suitable range for producing lettuce Lactuca sativa L. Artificial climate chamber experiments were conducted five (100, 200, 350, 500, 600 μmol·m −2 ·s −1...

Chemoreception is a key feature in selection of host plant by phytophagous insects, and odorant-binding proteins (OBPs) are involved chemical communication both insects vertebrates. The legume pod borer, Maruca vitrata Fabricius (Lepidoptera: Crambidae) one the pest species cowpea widely distributed throughout tropical subtropical regions, causing up to 80% yield loss. In this study, we investigated electrophysiological responses female M. floral volatiles from V. unguiculata. Seventeen...

We investigated the photosynthesis and growth of lettuce (Lactuca sativa L.) grown under three light/dark cycles in a mini plant factory with artificial illumination. A relative longer light cycle [12/12 h (light/dark)] increased not only light-response curve parameters, such as light-saturated net photosynthetic rate, light-saturation point, light-compensation dark respiration but also upregulated CO2-response curves CO2-saturated initial carboxylation efficiency, photorespiration compared...

Drought and salt stress are major abiotic that inhibit plants growth development, here we report a plasma membrane intrinsic protein ZmPIP1;1 from maize identified its function in drought tolerance Arabidopsis. was localized to the endoplasmic reticulum protoplasts. Treatment with PEG or NaCl resulted induced expression of root leaves. Constitutive overexpression transgenic Arabidopsis enhanced compared wild type. A number responsive genes involved cellular osmoprotection were up-regulated...

Rice (Oryza sativa) plant architecture and grain shape, which determine quality yield, are modulated by auxin brassinosteroid via regulation of cell elongation proliferation. We review the signal transduction these hormones crosstalk between their signals on rice shape.

Endoreplication, also called endoreduplication, is a modified cell cycle in which DNA repeatedly replicated without subsequent division. Endoreplication often associated with increased size and specialized shapes, but the mechanism coordinating content shape remains obscure. Here we identify product of BRANCHLESS TRICHOMES (BLT) gene, protein hitherto unknown function that has been conserved throughout angiosperm evolution, as link nuclear endoreplicated Arabidopsis trichomes....

Abstract Pheromone-binding proteins (PBPs) are essential for the filtering, binding and transporting of sex pheromones across sensillum lymph to membrane-associated pheromone receptors moths. In this study, three novel PBP genes were expressed in Escherichia coli examine their involvement perception Maruca vitrata . Fluorescence experiments indicated that MvitPBP1-3 had strong affinities with four pheromones. Moreover, molecular docking results demonstrated six amino acid residues MvitPBPs...

Anthocyanins confer the red color in hypocotyl of tartary buckwheat sprouts. Uridine diphosphate (UDP)-glucose:flavonoid 3-O-glycosyltransferase (UFGT) stabilizes anthocyanin by attaching glucosyl moiety from UDP-glucose to C3 hydroxyl anthocyanin. In this study, we characterized three UFGT-like genes, designated FtUFGT1, 2, and 3 buckwheat. The results revealed that FtUFGT2, FtUFGT3 can convert cyanidin 3-O-glucoside, with specific activities 20.01 × 10(-3), 8.93 20.24 10(-3) IU/mg,...
