Reduced height (Rht) genes have revolutionised wheat cultivation, but they can compromise freezing tolerance, and only a few alleles are in use. Thus, evaluating the role of other Rht stress responses is crucial. Far-red supplementation white light (W+FR) induce pre-hardening cereals at 15°C. However, relevant effect blue enrichment (W+B) poorly described. This study investigates influence W+FR or W+B exposure young winter leaves tall (wild-type, rht12) dwarf, gibberellin-deficient...
Salicylic acid (SA) is a key component of plant defence, which exerts concentration-dependent effect on photosynthesis under multi-faceted influence light. Photosynthetic activities and chloroplast morphology were studied in tomato plants after treatment with sublethal, 0.1 mM, cell death-inducing, 1 mM concentrations SA normal photoperiod during light phase prolonged dark phase. (1 mM) decreased the maximal (Fv/Fm) effective quantum yields PSII [Y(II)] PSI [Y(I)] both environmental...
Selenium (Se) enrichment of Stevia rebaudiana Bertoni can serve a dual purpose, on the one hand to increase plant biomass and stress tolerance other produce Se fortified plant-based food. Foliar spraying (0, 6, 8, 10 mg/L selenate, 14 days) plantlets resulted in slightly decreased stevioside rebaudioside A concentrations, it also caused significant increment stem elongation, leaf number, content, suggesting that foliar supplementation be used as biofortifying approach. Furthermore, limited...
The presence of solar radiation is one the most important environmental factors, which required for optimal growth and development plants. absence it (e.g. in night period or artificially prolonged darkness) can alter light-dependent signalling regulation pathways may induce new defence responses. Antioxidant enzymes as components plant system play a crucial role detoxification reactive oxygen species (ROS) induced by several stressors; however, their be different light dark. In this review...
It is well established that cold acclimation processes are highly influenced, apart from ambient temperatures, by light-dependent environmental factors. In this study we investigated whether an extra blue (B) light supplementation would be able to further improve the well-documented freezing tolerance enhancing effect of far-red (FR) enriched white (W) light. The impact B and FR (WFRB) on hormone levels lipid contents were determined in winter barley at moderate (15 °C) low (5 temperatures....
Exogenous ethylene (ET) or its precursor, 1-aminocyclopropane-1-carboxylic acid (ACC) may increase stress tolerance of plants in long-term experiments. ACC applied hydroponic culture tomato (Solanum lycopersicum L. cv. Rio Fuego) brought about concentration-dependent differences plant responses. at 0.01 µM changed K+ distribution between shoots and roots but higher concentrations K+/86Rb+ uptake was inhibited. Surprisingly, excess Na+ reduced accumulation could be measured root leaf tissues,...
Abstract Effects of ascorbate (ASA) and hydrogen peroxide (H 2 O ) on metabolite profile was compared in wheat. Interestingly, the redox environment became more oxidized after ASA treatment reduced H addition based ratios oxidised glutathione. The excess could inhibit, while induce oxidative pentose phosphate pathway producing reducing power as shown by unchanged decreased glucose-6-phosphate content, respectively. This different effect content can also explain formation several amino acids...
Soil salinity can limit the use of marginal lands for biomass production based on cultivation short-rotation woody crops as energy willow. Here, we compare salt stress responses diploid, productive cultivar (Energo), and its artificially produced autotetraploid (PPE-2; PPE-7; PPE-13) variants. After pre-testing effects various concentrations, willow plants with different genome sizes were exposed to 1.5 g NaCl kg−1 soil (electrical conductivity (EC) value: 7.04 mS/cm). Digital imaging shoot...
Hybrid vigor and polyploidy are genetic events widely utilized to increase the productivity of crops. Given that bioenergy usage needs be expanded, we investigated triploid hybrid in terms biology biomass-related willow traits their relevance control biomethane production. To produce genotypes, crossed two female diploid Swedish cultivars (Inger, Tordis) with male autotetraploid (Salix viminalis) variants (PP-E7, PP-E15). Field studies at locations successive years recorded considerable...
Exposure of tomato plants to dark period promotes leaf senescence, which takes place at different speed in young, mature and old leaves intact plants. Dark-induced senescence is accompanied with decreased glucose levels, chlorophyll content photosynthetic activity it induces changes sugar metabolism, hexokinases (HXKs) play a prominent role. The aim this work was reveal the expression various HXK genes positions kept darkness. A 24-h-long reduced mitochondrial SlHXK1 chloroplastic SlHXK4...
