Flowering of Arabidopsis thaliana is induced by exposure to long days (LDs). During this process, the shoot apical meristem converted an inflorescence that forms flowers, and transition maintained even if plants are returned short (SDs). We show five LDs sufficient commit SD-grown flower as they were exposed continuous LDs. The MADS box proteins SUPPRESSOR OF OVEREXPRESSION CONSTANS1 (SOC1) FRUITFULL (FUL) play essential roles in commitment process induction flowering downstream...
GH3 genes are main components of the hormonal mechanism regulating growth and development and, hence, deeply involved in a broad range physiological processes. They implicated homeostasis through conjugation to amino acids free form essential plant regulators such as indoleacetic jasmonic acids. In this work, we showed that OsGH3.1 overexpression rice caused dwarfism significantly reduced both auxin content cell elongation. Functional classification transcriptomic profiling revealed most...
Abstract Background MADS-domain transcription factors play important roles during plant development. The Arabidopsis MADS-box gene SHORT VEGETATIVE PHASE ( SVP ) is a key regulator of two developmental phases. It functions as repressor the floral transition vegetative phase and later it contributes to specification meristems. How these distinct activities are conferred by single factor unclear, but interactions with other MADS domain proteins which specify binding different genomic regions...
Arabidopsis FT protein is a component of florigen, which transmits photoperiodic flowering signals from leaf companion cells to the shoot apex. Here, we show that specifically binds phosphatidylcholine (PC) in vitro. A transgenic approach increase PC levels vivo meristem accelerates whereas reduced delay flowering, demonstrating are correlated with time. The early related activity, because expression FT-effector genes increased these plants. Simultaneous and apical further stimulates loss...
Significance In plants the transition from vegetative growth to flowering is induced by environmental cues. The amplitude of these responses enhanced repressors that strongly delay under non-inductive conditions. Arabidopsis thaliana , transcription factor SHORT VEGETATIVE PHASE (SVP) has a major role among repressors. We show SVP an unrecognized function in repressing biosynthesis plant regulator gibberellin (GA) at shoot apex. Under inductive photoperiods, expression falls, contributing...
Abstract Background Floral transition initiates reproductive development of plants and occurs in response to environmental endogenous signals. In Arabidopsis thaliana , this process is accelerated by several cues, including exposure long days. The photoperiod-dependent promotion flowering involves the transcriptional induction FLOWERING LOCUS T ( FT ) phloem leaf. encodes a mobile protein that transported from leaves shoot apical meristem, where it forms part regulatory complex induces...
Flowering of many plant species depends on interactions between basic leucine zipper (bZIP) transcription factors and systemically transported florigen proteins. Members the genus Arabidopsis contain two these bZIPs, FD FDP, which we show have largely complementary expression patterns in shoot apices before during flowering. CRISPR-Cas9-induced null mutants for FDP flower slightly earlier than wild-type, whereas fd are late Identical G-box sequences enriched at binding sites, but only binds...
Summary A group of MADS transcription factors (TFs) are believed to control temperature‐mediated bud dormancy. These TFs, called DORMANCY‐ASSOCIATED MADS‐BOX (DAM), encoded by genes similar SHORT VEGETATIVE PHASE ( SVP ) from Arabidopsis. proteins form transcriptional complexes whose combinatory composition defines their molecular function. However, how multimeric the dormancy cycle in trees is unclear. Apple MdDAM and other dormancy‐related with MdSVPa, which essential for ability bind DNA....
<h3>BACKGROUND</h3> X linked dominant Charcot-Marie-Tooth disease (CMT1X) is an inherited motor and sensory neuropathy that mainly affects the peripheral nervous system. CMT1X associated with mutations in gap junction protein connexin 32 (Cx32). Cx32 expressed Schwann cells oligodendrocytes (PNS) (CNS) respectively. <h3>METHODS</h3> A family a mutation was examined clinically electrophysiologically to determine whether PNS, or CNS, both pathways were affected. <h3>RESULTS</h3> In novel...
A great number of plants synchronize flowering with day length. In rice (Oryza sativa), photoperiod is the primary environmental cue that triggers flowering. Here, we show s73 mutant, identified in a gamma-irradiated Bahia collection, displays early and photoperiodic insensitivity due to null mutation PHOTOPERIOD SENSITIVITY5 (SE5) gene, which encodes an enzyme implicated phytochrome chromophore biosynthesis. mutant alterations characteristic diurnal expression patterns master genes involved...
Abstract Background Improvement of Citrus , the most economically important fruit crop in world, is extremely slow and inherently costly because long-term nature tree breeding an unusual combination reproductive characteristics. Aside from disease resistance, major commercial traits are improved quality, higher yield tolerance to environmental stresses, especially salinity. Results A normalized full length 9 standard cDNA libraries were generated, representing particular treatments tissues...
We investigated tolerance to high salinity in well-irrigated diploid and tetraploid citrus. Comparisons were made between two diploids (2×) of trifoliate orange (Poncirus trifoliata (L.) Raf.) willow leaf mandarin (Citrus deliciosa Ten), their respective doubled (4×) the allotetraploid (FLHORAG1) obtained from protoplast fusion Willow mandarin. Salinity stress was applied by progressively increasing concentration NaCl 50 mM 400 for 8 weeks. Two-year-old plants watered daily. Maximum quantum...
Flowers form on the flanks of shoot apical meristem (SAM) in response to environmental and endogenous cues. In Arabidopsis (Arabidopsis thaliana), photoperiodic pathway acts through FLOWERING LOCUS T (FT) promote floral induction day length. A complex between FT basic leucine-zipper transcription factor FD is proposed SAM, leading activation APETALA1 LEAFY thereby promoting identity. We identified mutations that suppress function recovered a new allele homeodomain PENNYWISE (PNY). Genetic...
Summary Long days repeatedly enhance the expression of FLOWERING LOCUS T ( FT ) gene during evening and early night. This signal induces flowering despite low rest day. To investigate whether this temporal behaviour transmits information, plants Arabidopsis thaliana were exposed to different day–night cycles, including combinations that induced out normal hours. Flowering time best correlated with integral over several days, corrected for a higher night sensitivity . We generated system...
In the Mediterranean basin, limited availability of rice genetic resources restricts success breeding programs. Although mutation induction is a powerful alternative to generate desired novel variations, current mutant have little relevance in programs that require well-adapted cultivars for maximum performance. this work genome-wide has been used on cv Bahia, japonica cultivar well adapted climate and cultural practices, increase its variability facilitate generation selection interesting...
Glycerolipid composition in plant membranes oscillates response to diurnal change. However, its functional significance remained unclear. A recent discovery that Arabidopsis florigen FT binds diurnally oscillating phosphatidylcholine molecules promote flowering suggests oscillation of glycerolipid is an important input time control. Taking advantage public microarray data, we globally analyzed the expression pattern biosynthetic genes under long-day, short-day, and continuous light...
Several pathways conferring environmental flowering responses in Arabidopsis (Arabidopsis thaliana) converge on developmental processes that mediate the floral transition shoot apical meristem. Many characterized mutations disrupt these responses, but downstream have been more refractory to mutagenesis. Here, we constructed a quintuple mutant impaired several and showed it possesses severely reduced changes photoperiod ambient temperature. RNA-sequencing (RNA-seq) analysis of expression...
