Carnivorous plants exploit animals as a nutritional source and have inspired long-standing questions about the origin evolution of carnivory-related traits. To investigate molecular bases carnivory, we sequenced genome heterophyllous pitcher plant Cephalotus follicularis, in which succeeded regulating developmental switch between carnivorous non-carnivorous leaves. Transcriptome comparison two leaf types gene repertoire analysis identified genetic changes associated with prey attraction,...
Most plants grow and develop by taking up nutrients from the soil while continuously under threat foraging animals. Carnivorous have turned tables capturing consuming nutrient-rich animal prey, enabling them to thrive in nutrient-poor soil. To better understand evolution of botanical carnivory, we compared draft genome Venus flytrap (Dionaea muscipula) with that its aquatic sister, waterwheel plant Aldrovanda vesiculosa, sundew Drosera spatulata. We identified an early whole-genome...
Abstract On macroevolutionary timescales, extensive mutations and phylogenetic uncertainty mask the signals of genotype–phenotype associations underlying convergent evolution. To overcome this problem, we extended widely used framework non-synonymous to synonymous substitution rate ratios developed novel metric ω C , which measures error-corrected convergence protein While distinguishes natural selection from genetic noise errors in simulation real examples, its accuracy allows an...
Abstract The origins of multicellular physiology are tied to evolution gene expression. Genes can shift expression as organisms evolve, but how ancestral influences altered descendant is not well understood. To examine this, we amalgamate 1,903 RNA-seq datasets from 182 research projects, including 6 organs in 21 vertebrate species. Quality control eliminates project-specific biases, and shifts reconstructed using gene-family-wise phylogenetic Ornstein–Uhlenbeck models. Expression following...
Bitter gourd (Momordica charantia L.) is a popular tropical vegetable in Asian countries. Previously it was shown that bitter placenta extract suppressed lipopolysaccharide (LPS)-induced TNFα production RAW 264.7 macrophage-like cells. Here the butanol-soluble fraction of strongly suppresses LPS-induced Gene expression analysis using fibrous DNA microarray showed butanol various inflammatory genes, such as those for TNF, IL1α, IL1β, G1p2, and Ccl5. The significantly NFκB binding activity...
Abstract Complex morphology is an evolutionary outcome of phenotypic diversification. In some carnivorous plants, the ancestral planar leaf has been modified to form a pitcher shape. However, how development was altered during evolution remains unknown. Here we show that leaves Sarracenia purpurea develop through cell division patterns adaxial tissues are distinct from those in bifacial and peltate leaves, subsequent standard expression abaxial marker genes. Differences orientation divisions...
Polygonum cuspidatum (Japanese knotweed, also known as Huzhang in Chinese), a plant that produces bioactive components such stilbenes and quinones, has long been recognized important traditional Chinese herbal medicine. To better understand the biological features of this to gain genetic insight into biosynthesis its natural products, we assembled draft genome P. using Illumina sequencing technology. The is ca. 2.56 Gb long, with 71.54% annotated transposable elements. Integrated gene...
Plants recognize surrounding microbes by sensing microbe-associated molecular patterns (MAMPs) to activate pattern-triggered immunity (PTI). Despite their significance for microbial control, the evolution of PTI responses remains largely uncharacterized. Here, employing comparative transcriptomics six Arabidopsis thaliana accessions and three additional Brassicaceae species investigate responses, we identified a set genes that commonly respond MAMP flg22 exhibit species-specific expression...
Abstract Background Leaf economic theory holds that physiological constraints to photosynthesis have a role in the coordinated evolution of multiple leaf traits, an idea can be extended carnivorous plants occupying particular trait space is constrained by key costs and benefits. Pitcher traps are modified leaves may face steep photosynthetic costs: high-volume, three-dimensional tubular structure less efficient than flat lamina. While past research has investigated pitchers, exact suite...
Abstract Harnessing plant genetic resources including wild plants enables exploitation of agronomically unfavorable lands to secure food in the future. The genus Vigna , family Fabaceae, consists many species such kind, as they are often adapted harsh environments marine beach, arid sandy soil, acidic limestone karst and marshes. Here we report long-read assemblies 12 species, achieving 95% or higher BUSCO scores. comparative analyses discovered a new class WUSCHEL -related homeobox ( WOX )...
Cleistogamy, in which plants can reproduce via self-fertilization within permanently closed flowers, has evolved > 30 angiosperm lineages; however, consistent with Darwin's doubts about its existence, complete cleistogamy - the production of only cleistogamous flowers rarely been recognized. Thus far, achlorophyllous orchid genus, Gastrodia, is known genus several plausible completely species. Here, we analyzed floral developmental transcriptomes two recently evolved, Gastrodia species and...
To clarify the evolutionary dynamics of ribosomal RNA genes (rDNAs) in Byblis liniflora complex (Byblidaceae), we investigated 5S and 45S rDNA through (1) chromosomal physical mapping by fluorescence situ hybridization (FISH) (2) phylogenetic analyses using nontranscribed spacer (5S-NTS) internal transcribed (ITS). In addition, performed based on rbcL trnK intron. The was divided into 2 clades: B. aquatica-B. filifolia guehoi-B. liniflora-B. rorida. Although members had conservative...
Drosera spathulata complex, which consists of diploid, tetraploid and hexaploid populations, is widely but disjunctively distributed from eastern part Australia throughout the South East Asian countries, to Japan. Among these high morphological changing has been found in this species. To investigate intraspecific DNA polymorphism, infer polyploid origin, some populations cultivars complex close related species were investigated using molecular cluster analysis with nucleotide sequences large...
North American lake cress, Rorippa aquatica (Eaton) EJ Palmer & Steyermark (Brassicaceae), is listed as an endangered or threatened species. Lake cress shows heterophyllic changes in leaf form response to the surrounding environment. Therefore, this species has received considerable attention from ecological and morphological perspectives. However, its phylogenetic position taxonomic status have long been a subject of debate. To analyze relationship we investigated chloroplast DNA sequences...
Organisms withstand normal ranges of environmental fluctuations by producing a set phenotypes genetically programmed as reaction norm; however, extreme conditions can expose misregulation called hidden norm. Although an environment consists multiple factors, how combinations these factors influence norm is not well understood. To elucidate the combinatorial effects we studied leaf shape plasticity carnivorous pitcher plant Cephalotus follicularis . Clonally propagated plants were subjected...
Abstract Subgenome dominance after whole-genome duplication generates distinction in gene number and expression at the level of chromosome sets, but it remains unclear how this process may be involved evolutionary novelty. Here, we generated a chromosome-scale genome assembly Asian pitcher plant Nepenthes gracilis to analyze its novel traits (dioecy carnivorous leaves) are linked genomic evolution. We found decaploid karyotype with five complete sets syntenic chromosomes (2 n = 10 x 80) yet...
