Background Grafting has been extensively used to enhance the performance of horticultural crops. Since Charles Darwin coined term "graft hybrid" meaning that asexual combination different plant species may generate products are genetically distinct, highly discrepant opinions exist supporting or against concept. Recent studies have documented grafting enables exchanges both RNA and DNA molecules between partners, thus providing a molecular basis for grafting-induced genetic variation....
Natural resources of zeaxanthin are extremely limited. A Chlorella zofingiensis mutant (CZ-bkt1), which could accumulate high amounts zeaxanthin, was generated and characterized. CZ-bkt1 achieved by treating the algal cells with a chemical mutagen followed color-based colony-screening approach. found to consist dysfunctional carotenoid ketolase, leading accumulation rather than its downstream ketocarotenoid astaxanthin. Light irradiation, glucose, NaCl, nitrogen deficiency all induced...
Continuously increasing global temperatures present great challenges to food security. Grain size, one of the critical components determining grain yield in rice (Oryza sativa L.), is a prime target for genetic breeding. Thus, there an immediate need improvement maintain under heat stress. However, quantitative trait loci (QTLs) endowing stress tolerance and size are extremely rare. Here, we identified novel negative regulator with pleiotropic effects, Thermo-Tolerance Length 1 (TTL1), from...
Japonica rice has become increasingly popular in China owing to its superior grain quality. Over the past decades, "indica japonica" projects have been proposed promote cultivation of japonica low latitudes China. Traditionally, varieties were planted mainly mid northeast plain and Yangtze River region. The key obstacle for introducing elite mid-latitude is severe shortening growth period due their sensitivity low-latitude short photoperiod high temperature. Here we report development new...
Abstract Background Serotonin, originally identified as a neurotransmitter in mammals, functions an antioxidant to scavenge cellular ROS plants. In rice, the conversion of tryptamine serotonin is catalyzed by SL (sekiguchi lesion), member cytochrome P450 monooxygenase family. The sl mutant, originated from rice cultivar Sekiguchi-asahi, exhibits spontaneous lesions, whereas its immune responses pathogens have not been clearly characterized. Results Here we three allelic mutants indica...
Dioscorea cirrhosa L. ( D. ) tuber is a traditional medicinal plant that abundant in various pharmacological substances. Although diosgenin commonly found many Dioscoreaceae plants, its presence remained uncertain. To address this, HPLC-MS/MS analysis was conducted and 13 metabolites were identified tuber. Furthermore, we utilized transcriptome data to identify 21 key enzymes 43 unigenes are involved biosynthesis, leading proposed pathway for biosynthesis . A total of 3,365 belonging 82...
Plants with mutations in one of three maize genes, mop1, rmr1, and rmr2, are defective paramutation, an allele-specific interaction that leads to meiotically heritable chromatin changes. Experiments reported here demonstrate these genes required maintain the transcriptional silencing two different transgenes, suggesting paramutation transgenes share mechanisms. We hypothesize silenced through RNA-directed mechanism, because mop1 encodes RNA-dependent RNA polymerase. In all mutants, DNA...
Significance The filamentous cyanobacterium Anabaena has become a widely studied model to determine the molecular mechanisms involved in establishing and maintaining pattern of heterocyst differentiation response removal fixed nitrogen from environment. Heterocysts develop vegetative cells, usually spaced about 10 cells apart, converting an oxic cell capable division into anoxic factory for fixation that does not divide. Genetic analysis elucidate intercellular material exchange between...
The bacterium Novosphingobium sp. THN1 (THN1) is capable of degrading microcystin-LR (MC-LR). To study the ability to degrade MC-LR and its possible mechanism(s) regulation, we analyzed effect carbon concentrations on degradation process. rate peaked early then declined during biodegradation. Decreased levels in medium caused peak occur earlier. expression functional gene mlrA, encoding a microcystinase, showed similar trend at various (r2 = 0.717, p < 0.05), suggesting that regulation mlrA...
Cyanophage MaMV-DC is a member of Myoviridae that was reported to specifically infect and lyse Microcystis aeruginosa FACHB-524 among 21 selected cyanobacterial strains. We reidentified the infection specificity seven other strains different species. In our experiments, infected three but did not form plaque in lawns. This indicated at least genus- rather than strain-specific virus. genes were transcribed M. FACHB-524, flos-aquae TF09, TA09 wesenbergii DW09, growth these inhibited by...
Microalgae are competitive and commercial sources for health-benefit carotenoids. In this study, a Chromochloris zofingiensis mutant (Cz-pkg), which does not shut off its photosystem stays green upon glucose treatment, was generated characterized. Cz-pkg developed by treating the algal cells with chemical mutagen as N-methyl-N'-nitro-N-nitrosoguanidine followed color-based colony screening approach. found to contain dysfunctional cGMP-dependent protein kinase (PKG). By cultivated CO2...
Rice (Oryza sativa) straw is a common waste product that represents considerable amount of bound energy. This energy can be used for biogas production, but the rate and level methane produced from rice still low. To investigate potential an increased production straw, we have here utilized WRINKLED1 (WRI1), plant AP2/ERF transcription factor, to increase triacylglycerol (TAG) biosynthesis in plants. Two forms Arabidopsis thaliana WRI1 were evaluated by transient expression stable...
Pyrabactin resistance-like (PYL) proteins were identified as receptors of the plant hormone ABA. The PYL family consists multiple members that are differently expressed in various tissues, exhibit distinct biochemical properties and have diverse biological functions. In present study, we explored expression patterns rice (Oryza sativa L.) OsPYL genes determined OsPYL8 OsPYL9 specifically endosperms. Sequence analysis deletion experiments revealed promoters contain motifs involved...
