Main conclusion Epigenetic memory affects the timing of bud burst phenology and the expression of bud burst-related genes in genetically identical Norway spruce epitypes in a manner usually associated with ecotypes.In Norway spruce, a temperature-dependent epigenetic memory established during embryogenesis affects the timing of bud burst and bud set in a reproducible and predictable manner. We hypothesize...
Main conclusionPepper leucine-rich repeat protein (CaLRR1) interacts with defense response proteins to regulate plant cell death and immunity. This review highlights the current understanding of the molecular functions of CaLRR1 and its interactor proteins.Plant cell death and immune responses to microbial pathogens are controlled by complex and tightly regulated molecular signaling networks. Xanthomonas campestris...
Main conclusionSevere leaf removal decreases storage starch and sucrose in grapevine cv. Cabernet Sauvignon fruiting cuttings and modulates the activity of key enzymes and the expression of sugar transporter genes.Leaf removal is an agricultural practice that has been shown to modify vineyard efficiency and grape and wine composition. In this study, we took advantage of the ability to precisely control...
Main conclusionABP9, encoding a bZIP transcription factor from maize, enhances tolerance to multiple stresses and may participate in the ABA signaling pathway in transgenic cotton by altering physiological and biochemical processes and stress-related gene expression.Abiotic stresses, such as soil salinity and drought, negatively affect growth, development, and yield in cotton. Gene ABP9, which encodes...
Main conclusionOur findings suggest a new approach to pollen ontogenetic investigations, entailing consideration of physical factors, which enable a better understanding of exine developmental processes.The sporopollenin-containing part of the pollen wall—the exine—is one of the most complex cell walls in plants. By tracing each stage of microspore development in Larix decidua with TEM, we aimed to...
Main conclusion This study provides new insights into the biosynthesis regulation andin plantafunction of the lignan yatein in flax leaves.Pinoresinol–lariciresinol reductases (PLR) catalyze the conversion of pinoresinol into secoisolariciresinol (SECO) in lignan biosynthesis. Several lignans are accumulated in high concentrations, such as SECO accumulated as secoisolariciresinol diglucoside (SDG)...
Main conclusionExogenously applied 2% fructose is the most appropriate carbon source that enhances photosynthesis and growth of grape plantlets compared with the same concentrations of sucrose and glucose. The role of the sugars was regulated by the expression of key candidate genes related to hormones, key metabolic enzymes, and sugar metabolism of grape plantlets (Vitis viniferaL.) grown in vitro....
Main conclusionDuring spring, bud growth relies on long-distance transport of remotely stored carbohydrates. A new hypothesis suggests this transport is achieved by the interplay of xylem and phloem.During the spring, carbohydrate demand of developing buds often exceeds locally available storage, thus requiring the translocation of sugars from distant locations like limbs, stems and roots. Both the...
Main conclusionTobacco germinated and grew in the presence of high concentrations of cadmium and zinc without toxic symptoms. Evidence suggests that these ions are sequestered into the vacuole by heavy metal/H+exchanger mechanisms.Heavy metal hyperaccumulation and hypertolerance are traits shared by a small set of plants which show specialized physiological and molecular adaptations allowing them...
Main conclusion The changes in the reproductive barrier between hexaploid wheat (Triticum aestivumL.) and rye (Secale cerealeL.) can be induced using in situ embryo rescue of abnormal embryos, yielding stable fertile amphidiploid plants.In intergeneric crosses between hexaploid wheat (Triticum aestivum L.) and rye (Secale cereale L.), postzygotic barriers may occur at different stages of hybrid development...
Main conclusionThe 5′UTR ofSBgLRenhances gene expression by regulating both its transcription and translation.SBgLR (Solanum tuberosum genomic lysine rich) is a pollen-specific gene in Solanum tuberosum that encodes a microtubule-associated protein. The region from −85 to +180 (transcription start site at +1) was determined to be critical for specific expression in pollen grains. Transient and stable...
Main conclusionDrought stress during grain filling is the most yield-damaging to wheat. Pre-drought priming facilitated the wheat plants to sustain grain development against the post-anthesis drought stress by modulating the levels of growth hormones.Post-anthesis drought stress substantially reduces grain yield in wheat (Triticum aestivum L.) due to impaired grain development associated with imbalanced...
Main conclusionX-ray microtomography results revealed that delignification process damaged the oil palm fibers, which correlated well with reduction of lignin components and increase of the phenolic content.Biodegradation investigation of natural fibers normally focuses on physico-chemical analysis, with less emphasis on physical aspect like fiber structures affect from microbial activity. In this...
Main conclusionThe plant LIMs comprise two sub-families with one (DA1/DAR) and two (2LIM) LIM domains. This review comprehensively discussed the structure and potential role of this protein family in diverse area of plant biology.The description of first eukaryote lineage-specific plant LIM domain (LIN11, ISL1, and MEC3) proteins was observed in Helianthus long back. The successive study of LIM proteins...
Main conclusion A simple, low cost and safe method using homemade filter paper-based 96-well spin plates and homemade solutions was developed for high throughput plant DNA extraction to use in molecular marker analysis.A low cost and safe method was developed for high throughput extraction of plant DNA for molecular marker analysis. In this method, we describe a simple way to prepare 96-well spin...
Main conclusionExpression ofbHLH104-GFPdriven by theMYB72promoter improves plants’ tolerance to Fe deficiency and increases seed Fe concentrations.Iron (Fe) deficiency causes reduced crop yield and quality. In humans, Fe deficiency is directly associated with Fe-deficiency anemia. Therefore, breeding Fe-deficiency tolerant and Fe-enriched plants are an ideal approach to deal with these problems. Here,...
