Plants have evolved sensitive signaling systems to fine-tune photomorphogenesis in response changing light environments. Light and low temperatures are known regulate the expression of COLD REGULATED (COR) genes COR27 COR28, which influence circadian clock, freezing tolerance, flowering time. Blue stabilizes COR28 proteins, but underlying mechanism is unknown. We therefore performed a yeast two-hybrid screen using COR27- as bait identified E3 ubiquitin ligase CONSTITUTIVE PHOTOMORPHOGENIC1...
Abstract Cryptochromes (CRYs) are evolutionarily conserved photolyase-like photoreceptors found in almost all species, including mammals. CRYs regulate transcription by modulating the activity of several factors, but whether and how they affect pre-mRNA processing unknown. Photoperiod temperature closely associated seasonal cues that influence reproductive timing plants. mediate photoperiod-responsive floral initiation, it is largely unknown also involved thermosensory flowering. We...
This study investigated resistance evolution mechanisms of conjugated plasmids and bacterial hosts under different concentrations antibiotic pressure. Ancestral strain ECNX52 was constructed by introducing the
Summary BRI1‐EMS‐SUPPRESSOR 1 (BES1) functions as a key regulator in the brassinosteroid (BR) pathway that promotes plant growth. However, whether BES1 is involved photoperiodic flowering unknown. Here we report acts positive of flowering, but it cannot directly bind FLOWERING LOCUS T (FT) promoter. BR ENHANCED EXPRESSION ( BEE1 ) direct target and downstream BES1. also flowering. binds to FT chromatin activate transcription promote initiation. More importantly, blue light photoreceptor...
Protocols were developed for the generation of haploid and doubled plants from isolated microspores carrot (Daucus carota L.). Forty-seven accessions, including six inbred lines, 11 cultivars, 20 F1s, two BC1F1s, four F2s, one F3, three F4s, screened to evaluate genotype influence on microspore embryogenesis over 4 years. Twenty-eight accessions responded by producing embryos and/or calli. A cytological analysis showed that modes exist: an indirect route via calli (C mode), a direct (E...

Abstract In this study, the colonization of arbuscular mycorrhizas (AM) and dark septate endophytes (DSE) in 140 specimens 32 hydrophytes collected from four lakes streams southwest China were investigated. The mycorrhizal fungi (AMF) DSE these rare. Typical AM structures observed one 25 hydrophytic species six 17 streams. Spores 10 identified AMF an unidentified Acaulospora sp. isolated sediments. came genera, Acaulospora, Gigaspora, Glomus Scutellospora . G. mosseae dominant genus...
The phylogenetic positions of 60 bacterial strains isolated from three tailing piles were determined by analyzing their partial 16S rRNA gene sequences. These divided into phylogenetically distinct groups Arthrobacter and likely represented several non-described species. physiological diversities these geographically populations evaluated based on resistance to five heavy metals (Zn, Pb, Cd, Cu Co) four antibiotics (Kan, Rif, Str Amp), differences in utilization 49 carbon sources. Genetic...
Abstract Maize ( Zea mays L.) is a monoecious grass plant in which mature male and female florets form the tassel ear, respectively. often used as model to study flower development. Several maize seed mutants, such recessive mutants tasselseed1 ts1 ) tasselseed2 ts2 ), exhibit reversal sex determination, leads generation of seeds tassels. The phenotype dominant mutant, Tasselseed5 Ts5 similar that . Here, we positionally cloned underlying gene characterized its function. We show...
Cryptochromes (crys) are photolyase-like blue-light receptors first discovered in Arabidopsis thaliana and later identified all major evolutionary lineages. Crys involved not only blue light responses but also temperature responses; however, whether how cry protein stability is regulated by remains unknown. Here, we show that cry2 abundance modulated ambient degraded under low via the 26S proteasome. Consistent with this, shows high levels of ubiquitination temperatures. Interestingly,...
In recent years, polymyxin has been used as a last-resort therapy for carbapenem-resistant bacterial infections. The emergence of heteroresistance (HR) to hampers the efficacy treatment by amplifying resistant subpopulation. However, mechanisms behind HR remain unclear. Small noncoding RNAs (sRNAs) play an important role in regulating drug resistance. purpose this study was investigate effects and sRNA on B (PB)-HR Klebsiella pneumoniae. study, novel PhaS identified transcriptome sequencing....
The ectomycorrhizal fungus Thelephora ganbajun is an endemic gourmet mushroom in Yunnan province, south-western China. However, despite its widespread consumer appeal, nutritional value and potential ecological role natural forests, very little known about genetics, diversity ecology. In this study, we investigated DNA sequence variation at the internal transcribed spacer (ITS) regions among 156 specimens collected from 23 sites of nine Province. Our analysis identified a total 34 ITS...
Abstract Petaloid cytoplasmic male sterility (CMS) is a maternally inherited loss of fertility due to the complete conversion stamens into petal-like organs, and CMS lines have been widely utilized in carrot breeding. an ideal model not only for studying mitochondrial–nuclear interaction but also discovering genes that are essential floral organ development. To investigate comprehensive mechanism homeotic alternation during flower development, we conducted transcriptome analysis between...
Within the family Entolomataceae, many reports of Entoloma and Rhodocybe have been published, but few on Clitopilus allied genera are available. In this study, Clitopilus, Clitocella, Clitopilopsis from China were studied by morphological phylogenetic methods. Portions nuc 28S rDNA (28S), RNA polymerase II second largest subunit (rpb2), translation elongation factor 1-alpha (tef1), ATPase 6 (atp6), employed to elucidate relationships allies. Results indicate that should be divided into three...
A bacterial strain, RS-LYSO-3T, was isolated from tobacco-cultivated soil, collected near Chuxiong, Yunnan province, southwestern China. RS-LYSO-3T could effectively inhibit the invasion of powdery mildew on tobacco. The colonies were pale yellow, and its cells Gram-stain-negative rod-shaped, with 68 mol% DNA G+C content. Gene sequence analysis for 16S rRNA gene revealed highest similarity (97.78 %) that Lysobacter spongiicolaKMM 329T. Chemotaxonomic data showed possesses a quinone system...
Abstract Carrot ( Daucus carota L.) is a biennial plant requiring vernalization to induce flowering, but long days can promote its premature bolting and flowering. The basic genetic network controlling the flowering time has been constructed for carrot, there limited information on molecular mechanisms underlying photoperiodic response. published carrot genome could provide an effective tool systematically retrieving key integrator genes of GIGANTEA GI ), CONSTANS-LIKE COL FLOWERING LOCUS T...
