Amborella trichopoda is strongly supported as the single living species of sister lineage to all other extant flowering plants, providing a unique reference for inferring genome content and structure most recent common ancestor (MRCA) angiosperms. Sequencing genome, we identified an ancient duplication predating angiosperm diversification, without evidence subsequent, lineage-specific duplications. Comparisons between angiosperms facilitated reconstruction ancestral gene order in MRCA core...
Genomic comparisons provide evidence for ancient genome-wide duplications in a diverse array of animals and plants. We developed birth–death model to identify genome duplication EST data, applied mixture estimate the age distribution paralogous pairs identified sets species representing basal-most extant flowering plant lineages. found episodes basal angiosperm lineages including Nuphar advena (yellow water lily: Nymphaeaceae) magnoliids Persea americana (avocado: Lauraceae), Liriodendron...
The crucifer Arabidopsis thaliana has been used widely as a model organism for the study of plant development. We describe here development an efficient insertional mutagenesis system in that permits identification genes by their patterns expression during Transposable elements Ac/Ds carrying GUS reporter gene have designed to act enhancer traps or traps. A novel selection scheme maximizes recovery unlinked transposition events. In this 491 plants independent transposon insertions were...
Xie and colleagues previously isolated the Arabidopsis COI1 gene that is required for response to jasmonates (JAs), which regulate root growth, pollen fertility, wound healing, defense against insects pathogens. In this study, we demonstrate associates physically with AtCUL1, AtRbx1, either of Skp1-like proteins ASK1 or ASK2 assemble ubiquitin-ligase complexes, have designated SCFCOI1. COI1E22A, a single amino acid substitution in F-box motif COI1, abolishes formation SCFCOI1 complexes...
Abstract In flowering plants, tapetum degeneration is proposed to be triggered by a programmed cell death (PCD) process during late stages of pollen development; the PCD thought provide cellular contents supporting wall formation and allow subsequent release. However, molecular basis regulating in plants remains poorly understood. We report isolation characterization rice (Oryza sativa) male sterile mutant retardation (tdr), which exhibits middle layer as well collapse microspores. The TDR...
Abstract The basic/helix-loop-helix (bHLH) transcription factors and their homologs form a large family in plant animal genomes. They are known to play important roles the specification of tissue types animals. On other hand, few bHLH proteins have been studied functionally. Recent completion whole genome sequences model plants Arabidopsis (Arabidopsis thaliana) rice (Oryza sativa) allows genome-wide analysis comparison flowering plants. We identified 167 genes genome, phylogenetic indicates...
The predicted products of floral homeotic genes, AGAMOUS (AG) from Arabidopsis thaliana and DEFICIENS A (DEF A) Antirrhinum majus, have been shown previously to share strong sequence similarity with transcription factors humans (SRF) yeast (MCM1). conserved between these proteins is localized within a domain known be necessary for the DNA binding dimerization SRF. We isolated six new genes A. thaliana, AGL1-AGL6, which also this motif. On basis comparison AG AGL they can assigned two...

Cell differentiation is essential for the development of multicellular organisms. In flowering plants, haploid male gametophytes (pollen grains) are generated in anther from reproductive cells called microsporocytes. Several types somatic ensure successful pollen development, and thus reproduction. However, it not clear what genes regulate these diverse, highly specialized anther. We report here isolation characterization a novel Arabidopsis thaliana sterile mutant, excess microsporocytes1 (...
In flowering plants, male fertility depends on proper cell differentiation in the anther. However, relatively little is known about genes that regulate anther and function. Here, we report analysis of a new Arabidopsis sterile mutant, dysfunctional tapetum1 (dyt1). The dyt1 mutant exhibits abnormal morphology beginning at stage 4, with tapetal cells have excess and/or enlarged vacuoles lack densely stained cytoplasm typical normal cells. meiocytes are able to complete meiosis I, but they do...
Gene duplication plays important roles in organismal evolution, because duplicate genes provide raw materials for the evolution of mechanisms controlling physiological and/or morphological novelties. can occur via several mechanisms, including segmental duplication, tandem and retroposition. Although duplications have been found to be expansion a number multigene families, contribution retroposition is not clear. Here we show that plant SKP1 evolved by multiple events from single ancestral...
Abstract Angiosperms are the most successful plants and support human livelihood ecosystems. Angiosperm phylogeny is foundation of studies gene function phenotypic evolution, divergence time estimation biogeography. The relationship five divergent groups Mesangiospermae (~99.95% extant angiosperms) remains uncertain, with multiple hypotheses reported in literature. Here transcriptome data sets obtained from 26 species lacking sequenced genomes, representing each groups: eudicots, monocots,...
Members of the SEPALLATA (SEP) MADS-box subfamily are required for specifying "floral state" by contributing to floral organ and meristem identity. SEP genes have not been detected in gymnosperms seem originated since lineage leading extant angiosperms diverged from gymnosperms. Therefore, both functional evolutionary studies suggest that may critical origin flower. To gain insights into evolution genes, we isolated nine plants occupy phylogenetically important positions. Phylogenetic...
Abstract Background Although the overwhelming majority of genes found in angiosperms are members gene families, and both gene- genome-duplication pervasive forces plant genomes, some sufficiently distinct from all other a genome that they can be operationally defined as 'single copy'. Using clustering algorithm MCL-tribe, we have identified set 959 single copy shared genomes Arabidopsis thaliana, Populus trichocarpa, Vitis vinifera Oryza sativa . To characterize these genes, performed number...
Abstract Water lilies belong to the angiosperm order Nymphaeales. Amborellales, Nymphaeales and Austrobaileyales together form so-called ANA-grade of angiosperms, which are extant representatives lineages that diverged earliest from lineage leading mesangiosperms 1–3 . Here we report 409-megabase genome sequence blue-petal water lily ( Nymphaea colorata ). Our phylogenomic analyses support Amborellales as successive sister all other angiosperms. The N. 19 transcriptomes reveal a Nymphaealean...
F-box proteins are substrate-recognition components of the S kp1-Rbx1- C ul1- F -box protein (SCF) ubiquitin ligases. In plants, genes form one largest multigene superfamilies and control many important biological functions. However, it is unclear how why plants have acquired a large number genes. Here we identified 692, 337, 779 in Arabidopsis , poplar rice, respectively, studied their phylogenetic relationships evolutionary patterns. We found that plant superfamily can be divided into 42...
Brassicaceae is one of the most diverse and economically valuable angiosperm families with widely cultivated vegetable crops scientifically important model plants, such as Arabidopsis thaliana. The evolutionary history, ecological, morphological, genetic diversity, abundant resources knowledge make it an excellent family for studies. Recent phylogenetic analyses revealed three major lineages (I, II, III), but relationships among within these remain largely unclear. Here, we present a highly...
The development of anther and pollen is important for male reproduction, this process coordinately regulated by many external internal cues. In study, we systematically examined the reproductive phenotypes a series brassinosteroid biosynthetic signaling mutants found that, besides expected cell-expansion defects, these also showed reduced number, viability, release efficiency. These defects were related with abnormal tapetum microspore development. Using both real-time quantitative RT-PCR...
Abstract Hornworts, liverworts and mosses are three early diverging clades of land plants, together comprise the bryophytes. Here, we report draft genome sequence hornwort Anthoceros angustus . Phylogenomic inferences confirm monophyly bryophytes, with hornworts sister to mosses. The simple morphology correlates low genetic redundancy in plant body plan, while basic transcriptional regulation toolkit for development has already been established this lineage. Although is small characterized...
