In some plants, exposure to stress can induce a memory response, which appears play an important role in adaptation recurrent environments. However, whether rice exhibits drought and the molecular mechanisms that might underlie this process have remained unclear. Here, we ensured was established after cycles of mild re-watering treatment, studied gene expression by whole-transcriptome strand-specific RNA sequencing (ssRNA-seq). We detected 6,885 transcripts 238 lncRNAs involved grouped into...
The timing of flowering is pivotal for maximizing reproductive success under fluctuating environmental conditions. Flowering time tightly controlled by complex genetic networks that integrate endogenous and exogenous cues, such as light, temperature, photoperiod, hormones. Here, we show AGAMOUS-LIKE16 (AGL16) its negative regulator microRNA824 (miR824) control in Arabidopsis thaliana. Knockout AGL16 effectively accelerates nonvernalized Col-FRI, which the floral inhibitor FLOWERING LOCUS C...
FLOWERING LOCUS T (FT) regulates the floral transition in many plant species by integrating environmental seasonal signals and internal cues. Here we show that two interdependent regulatory regions are necessary sufficient to convey photoperiod responsiveness FT. While a minimal distance between is required fully suppress FT expression under short days, increased reduces promoter response long days. Natural variation at creating length differences widespread, correlates with longitudinal...
Prickles act against herbivores, pathogens or mechanical injury, while also preventing water loss. However, whether prickles have new function and the molecular genetics of prickle patterning remain poorly explored. Here, we generated a high-quality reference genome assembly for 'Basye's Thornless' (BT), prickle-free cultivar Rosa wichuraiana, to identify genetic elements related stem development. The BT harbors high level sequence diversity in itself with 'Old Blush' (R. chinensis), founder...
While roses are today among the most popular ornamental plants, petals and fruits of some cultivars have flavored foods for millennia. The genetic origins these edible remain poorly investigated. We collected major varieties available in China, assembled their plastome sequences, phased haplotypes internal transcribed spacers (ITS1/ITS2) 18S-5.8S-26S nuclear ribosomal cistron. Our phylogenetic reconstruction using 88 plastid genomes, primarily maternal origin, uncovered well-supported...
Abstract Background The Rhododendron sanguineum complex is endemic to alpine mountains of northwest Yunnan and southeast Tibet China. Varieties in this exhibit distinct flower colors even at the bud stage. However, underlying molecular regulations for color variation have not been well characterized. Here, we investigated via measuring reflectance profiles comparative transcriptome analyses on three coexisting varieties R. complex, with yellow flush pink, bright crimson, deep blackish...
Species that express the inflated calyx syndrome (ICS) are found in several genera of Solanaceae. The MADS-box protein MPF2, together with plant hormones cytokinin and gibberellin, has been shown to be responsible for this trait Physalis floridana. We have used sequence data from 114 species belonging 35 construct a molecular phylogeny Apart 2 Witheringia analyzed, within given genus cluster on resulting cladogram. solanacea is embedded Physalinae, but coccoloboides placed basal Iochrominae....
In plants and animals, gene expression can be down-regulated at the posttranscriptional level by microRNAs (miRNAs), a class of small endogenous RNA. Comparative analysis miRNA content across species indicates continuous birth death these loci in course evolution. However, little is known about microevolutionary dynamics genetic elements, especially plants. this article we examine polymorphism two miRNA-encoding Arabidopsis thaliana, miR856 miR824, which are not found rice or poplar. We...
Cis-regulatory DNA has been suspected to play a preeminent role in adaptive evolution, but understanding the of cis-regulatory mutations gene expression divergence first requires an accurate analysis functional differences associated with these regions. We analyzed allele-specific (ASE) leaf and floral tissues F1 interspecific hybrids generated between two closely related species Arabidopsis thaliana A. lyrata whole-genome SNP (single nucleotide polymorphism) tiling array. observed 2,205...
Flowering transition is tightly coordinated by complex gene regulatory networks, in which AGAMOUS-LIKE 16 (AGL16) plays important roles. Here, we identified the molecular function and binding properties of AGL16 demonstrated its partial dependency on SUPPRESSOR OF CONSTANS 1 (SOC1) regulating flowering. bound to promoters more than 2,000 genes via CArG-box motifs with high similarity that SOC1 Arabidopsis (Arabidopsis thaliana). Approximately 70 flowering involved multiple pathways were...
Floral forms with an increased number of petals, also known as double-flower phenotypes, have been selected and conserved in many domesticated plants, particularly ornamentals, because their great economic value. The molecular genetic mechanisms that control this trait are therefore interest, not only for scientists, but breeders. In review, we summarize current knowledge the gene regulatory networks flower initiation development mutations lead to variation petal species. addition...
Abstract Roses are important woody plants featuring a set of traits that cannot be investigated in traditional model plants. Here, we used the restriction-site associated DNA sequencing (RAD-seq) technology to develop high-density linkage map backcross progeny (BC1F1) between Rosa chinensis ‘Old Blush’ (OB) and R. wichuraiana ‘Basyes’ Thornless’ (BT). We obtained 643.63 million pair-end reads identified 139,834 polymorphic tags were distributed uniformly rose genome. 2,213 reliable markers...
Early-diverging land plants such as mosses are known for their outstanding abilities to grow in various terrestrial habitats, incorporating tremendous structural and physiological innovations, well many lineage-specific genes. How these genes functional innovations evolved remains unclear. In this study, we show that a dual-coding gene YAN/AltYAN the moss Physcomitrella patens from pre-existing hemerythrin gene. Experimental evidence indicates is involved fatty acid lipid metabolism, oil...
Roses are important plants for human beings with pivotal economical and biological traits like continuous flowering, flower architecture, color scent. Due to frequent hybridization high genome heterozygosity, classification of roses their relatives remains a big challenge. Here, identify potential markers phylogenetic reconstruction reveal the patterns natural selection in roses, we generated sets quality comprehensive reference transcriptomes Rosa chinensis 'Old Blush' (OB) R. wichuriana...
Expression divergence is thought to be a hallmark of functional diversification between homologs post duplication. Modification in regulatory elements has been invoked explain expression after duplication for several MADS-box genes, however, verification reciprocal loss cis-regulatory lacking plants. Here, we report that the evolution MPF2-like genes entailed degenerative mutations core promoter CArG-box and an auxin response factor (ARF) binding element large 1(st) intron coding region....
Pseudostellaria heterophylla produces both closed (cleistogamous, CL) and open (chasmogamous, CH) flowers on the same individual but in different seasons. The production of CH CL might be response to environmental changes. To better understand molecular mechanisms flowering, we compared transcriptome two types examine differential gene expression patterns, identify regulatory networks that control flowering. Using RNA sequencing, identified homologues 428 Arabidopsis genes involved...
Flowering time, a key transition point from vegetative to reproductive growth, is regulated by an intrinsic complex of endogenous and exogenous signals including nutrient status. For hundreds years, nitrogen has been well known modulate flowering but the molecular genetic basis on how plants adapt ever-changing availability remains not fully explored. Here we explore Arabidopsis natural variation in time responds nitrate fluctuation. Upon change, detect accession- photoperiod-specific...
Roses are important horticultural plants with enormous diversity in flowers and flowering behavior. However, molecular regulation of time variation roses remains poorly characterized. Here, we report an expansion the FAR1/FRS-like genes that correlates well switch to prostrate-to-erect growth shoots upon Rosa wichuraiana 'Basye's Thornless' (BT). With availability high-quality chromosome-level genome assembly for BT developed recently, identified 91 RwFAR1/FRS-like genes, a significant...
