Main conclusion New non-destructive approach to evaluate the retting process was investigated. Increase of retting duration led to a decrease of VOCs emitted by plants and change of color and plant odor. The variation of VOCs and odor could be used as indicators for the degree of retting. Abstract In the hemp industry, retting is an upstream bioprocessing applied to the plants to facilitate the...
Main conclusionChenopodium ficifoliumflowered under long days despite much lower expression ofFLOWERING LOCUS Thomolog than under short days. Abstract Frequent duplications of the FLOWERING LOCUS T (FT) gene across various taxonomic lineages resulted in FT paralogs with floral repressor function, whereas others duplicates maintained their floral-promoting role. The FT gene has been confirmed as...
Main conclusion HSP60 gene family in pepper was analyzed through bioinformatics along with transcriptional regulation against multiple abiotic and hormonal stresses. Furthermore, the knockdown of CaHSP60-6 increased sensitivity to heat stress. Abstract The 60 kDa heat shock protein (HSP60) also known as chaperonin (cpn60) is encoded by multi-gene family that plays an important role in plant growth,...
Main conclusion β-sitosterol influences amino acids, carbohydrates, organic acids, and other metabolite metabolism and homeostasis largely contributing to better tolerance to water stress in white clover. Abstract β-sitosterol (BS) could act as an important plant growth regulator when plants are subjected to harsh environmental conditions. Objective of this study was to examine effects of BS on...
Main conclusion Andean tomatoes differed from the wild ancestor in the metabolic composition and the expression of genes related with mitochondrial functions, and environmental stresses, making them potentially suitable for breeding programmes. Abstract Traditional landraces or “criollo” tomatoes (Solanum lycopersicum L.) from Andean areas of Argentina, selected for their fruit quality, were analysed...
Main conclusion Suppression of the maize phytoglobin ZmPgb1.1 enhances tolerance against Clavibacter nebraskensis by promoting hypersensitive response mechanisms mediated by ethylene and reactive oxygen species. Abstract Suppression of the maize phytoglobin, ZmPgb1.1, reduced lesion size and disease severity in leaves following inoculation with Clavibacter nebraskensis, the causal agent of Goss’s...
Main conclusion A homologue of the ribosomal protein L22e, Rpf84, regulates root nodule symbiosis by mediating the infection process of rhizobia and preventing bacteroids from degradation in Robinia pseudoacacia. Abstract Ribosomal proteins (RPs) are known to have extraribosomal functions, including developmental regulation and stress responses; however, the effects of RPs on symbiotic nodulation...
Main conclusion The MIR160 family in Gossypium hirsutum and G. barbadense was characterized, and miR160a_A05 was found to increase cotton-fiber length by downregulating its target gene (ARF17) and several GH3 genes. Abstract Cotton fiber is the most important raw material for the textile industry. MicroRNAs are involved in regulating cotton-fiber development, but a role in fiber elongation has not...
Main conclusion DNA methylation of anthocyanin biosynthesis-related genes and MYB/bHLH transcription factors was associated with apple fruit skin color revealed by whole-genome bisulfite sequencing. Abstract DNA methylation is a common feature of epigenetic regulation and is associated with various biological processes. Anthocyanins are among the secondary metabolites that contribute to fruit colour,...
Main conclusion Specific combinations of physiological and molecular parameters associated with N and S remobilization measured at the onset of flowering were predictive of final crop performances in oilseed rape. Abstract Oilseed rape (Brassica napus L.) is a high nitrogen (N) and sulphur (S) demanding crop. Nitrogen- and S-remobilization processes allow N and S requirements to reproductive organs...
Main conclusionThe duplications of the dominantVrn-A1alleles as well as theVRN-B1gene, revealed for the first time, are new sources of polymorphism in polyploid wheat at these agronomically valuable genomic locations.Flowering time is an important trait in wheat breeding. In spring wheat, this feature is mainly determined by the variants and number of the homoeologous dominant VRN1 alleles. Previously,...
Main conclusion PbrKAT1, which is inhibited by external Na+ in Xenopus laevis oocytes, is characterized as encoding a typical inward rectifying channel that is mainly expressed in guard cells. Abstract Potassium (K+) is the most abundant cation in plant cells necessary for plant growth and development. The uptake and transport of K+ are mainly completed through transporters and channels, and the...
Main conclusion OsNF-YB9 controls heading by affecting expression of regulators of flowering. It affects the development of the reproductive meristem by interacting with MADS1 and controlling expression of hormone-related genes. Abstract Nuclear Factor-Y (NF-Y) family of transcription factors takes part in many aspects of growth and development in eukaryotes. They have been classified into three...
Main conclusion Ferulic acid esterases have been identified and partially purified from maize pollen. Results suggest that maize pollen FAEs may play an important role in pollen fertilization. Abstract A critical step in maize (Zea mays) seed production involves fertilization of the ovule by pollen, a process that relies on ability of the pollen tube to grow through the highly structured and feruloylated...
Main conclusion Two newly identified phytohormone cleaving esterases from Olea europaea are responsible for the glucosidase-initiated activation of the specialized metabolites ligstroside and oleuropein. Abstract Biosynthetic routes leading to the formation of plant natural products are tightly orchestrated enzymatic sequences usually involving numerous specialized catalysts. After their accumulation...
Main conclusion In the wheat TCMS line YS3038, the anther development is inhibited from late uninucleate stage to the binucleate stage. The disruption of energy metabolism pathways by aberrant transcriptional regulation causes the male sterility under low temperatures. Abstract The utilization of thermosensitive male sterile (TMS) lines provides a basis for two-line breeding. Previous work, including...
Main conclusionIn grape (Vitis), stilbene phytoalexins can either be in situ synthesized or transported to the site of response during powdery mildew infection, enhancing disease resistance. Abstract Resveratrol is a phytoprotective stilbenoid compound that is synthesized by stilbene synthase (STS) in response to biotic and abiotic stresses, and is also known to have health benefits in the human...
Main conclusion Totally, 48 loci responsible for six spike-related traits were identified in wheat, and a major locus QGl-4A for grain length was mapped and validated for marker-assisted selection in breeding. Abstract Wheat yield is determined by the number of spikes, number of grains per spike (GN), and one-thousand kernel weight (TKW), among which GN and TKW are greatly related to the spike development...
Main conclusion Ηeat and calcium treatments reprogram sweet cherry fruit metabolism during postharvest senescence as evidenced by changes in respiration, amino acid metabolism, sugars, and secondary metabolites shift. Abstract Heat and calcium treatments are used to improve postharvest fruit longevity; however, the exact mechanism remains poorly understood. To characterize the impact of these treatments...
