Main conclusionMild Cd stress-activated diphenyleneiodonium-sensitive superoxide production is utilized in root morphogenic responses, while severe Cd stress-induced robust rotenone-sensitive superoxide generation may lead to cell and root death. In barley, even a few minute exposure of roots to Cd concentration higher than 10 µM evoked a strong superoxide generation in the root transition zone. This...
Main conclusionThe durum wheat varieties from Ukraine, Russia, and Kazakhstan are characterized by the specific allelic composition of theVRNgenes that sharply distinguish them from theTriticum durumvarieties from other countries. For numerous varieties, theVRNalleles which previously were not found in tetraploid wheat were identified.The ability of wheat to adapt to a wide range of environmental...
Main conclusionBased on the effects of inorganic salts on chloroplast Fe uptake, the presence of a voltage-dependent step is proposed to play a role in Fe uptake through the outer envelope.Although iron (Fe) plays a crucial role in chloroplast physiology, only few pieces of information are available on the mechanisms of chloroplast Fe acquisition. Here, the effect of inorganic salts on the Fe uptake...
Main conclusionAtNPF3.1gene expression is promoted by limiting nitrogen nutrition.Atnpf3.1mutants are affected in hypocotyl elongation and seed germination under conditions of low-nitrate availability.The NITRATE TRANSPORTER1/PEPTIDE TRANSPORTER (NPF) family encodes nitrate or peptides transporters, some of which are also able to transport hormones. AtNPF3.1 has been described as a nitrate/nitrite/gibberellin...
Main conclusionGenome-wide screening ofSaccharomyces cerevisiaerevealed that signaling pathways related to the alkaline pH stress contribute to resistance to plant antimicrobial peptide, Pn-AMP1.Plant antimicrobial peptides (AMPs) are considered to be promising candidates for controlling phytopathogens. Pn-AMP1 is a hevein-type plant AMP that shows potent and broad-spectrum antifungal activity. Genome-wide...
Main conclusionTheL. regaleATP-binding cassette transporter gene,LrABCF1belonging to GCN subfamily, functions as a positive regulator of plant defense againstCucumber mosaic virus, Tobacco rattle virus, andBotrytis cinereain petunia.ATP-binding cassette (ABC) transporters are essential for membrane translocation in diverse biological processes, such as plant development and defense response. Here,...
Main conclusionBlue-light positive phototropism in roots is masked by gravity and revealed in conditions of microgravity. In addition, the magnitude of red-light positive phototropic curvature is correlated to the magnitude of gravity.Due to their sessile nature, plants utilize environmental cues to grow and respond to their surroundings. Two of these cues, light and gravity, play a substantial role...
Main conclusionGlobal warming will increase the incidence of metabolism-based reduced herbicide efficacy on weeds and, therefore, the risk for evolution of non-target site herbicide resistance.Climate changes affect food security both directly and indirectly. Weeds are the major biotic factor limiting crop production worldwide, and herbicides are the most cost-effective way for weed management. Processes...
Main conclusionThe molecular mechanism of low Cd influxes and accumulation inMiscanthus sacchariflorusis revealed by RNA sequencing technique.Soil cadmium (Cd) pollution has posed a serious threat to our soil quality and food security as well as to human health. Some wild plants exhibit high tolerance to heavy metals stress. However, mechanisms of Cd tolerance of wild plants remain to be fully clarified...
Main conclusionMicrosatellite and single nucleotide polymorphism markers that could be used in marker assisted breeding of cacao were identified for number of filled seeds, black pod resistance and witches’ broom disease resistance.An association mapping approach was employed to identify markers for seed number and resistance to black pod and witches’ broom disease (WBD) in cacao (Theobroma cacao...
Main conclusionSolanum tuberosumgenome analysis revealed 12StSULTRgenes encoding 18 transcripts. Among genes annotated at group level (StSULTRI–IV), group III members formed the largest SULTRs-cluster and were potentially involved in biotic/abiotic stress responses via various regulatory factors, and stress and signaling proteins.Employing bioinformatics tools, this study performed genome-wide identification...
Main conclusionForty-five molecular markers were detected significantly associated with chrysanthemum’ waterlogging tolerance, and four favorable parental lines were identified as potential donors for improving waterlogging tolerance in chrysanthemum.The productivity of chrysanthemum is downgraded by waterlogging soils, which has driven a search for germplasm showing an enhanced level of waterlogging...
