    Annotation of <i>Arabidopsis</i> by Sorghum MF Versus Rice Gene Sequences

    No full text
    <p>Shown are the number of <i>Arabidopsis</i> proteins that are matched in a TBLASTN comparison to the sorghum MF set (blue) versus the rice gene sequences (yellow). The <i>Arabidopsis</i> proteins, after having known repetitive elements removed (see <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0030013#s3" target="_blank">Materials and Methods</a>), have been categorized as either hypothetical or known based on the definition line. <i>Arabidopsis</i> proteins were considered supported if they matched with an E-value less than or equal to 1 × 10<sup>−8</sup>. Sb, S. bicolor MF set; Osj:seq, <i>Oryza sativa japonica</i> gene sequences.</p

    Phylogenetic Comparison of Sorghum <i>DREB1</i> Genes

    No full text
    <p>A phylogenetic tree comparing the AP2 domain of the sorghum <i>DREB1</i> genes to those of <i>Arabidopsis</i> and rice was constructed using CLUSTALX [<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.0030013#pbio-0030013-b61" target="_blank">61</a>]. The genes encoding proteins from <i>Arabidopsis</i> are <i>DREB1A, DREB1B,</i> and <i>DREB1C</i>. Rice genes are <i>OsDREB1A, OsDREB1B, OsDREB1C</i> (nucleotides 142,337–142,981), and <i>OsDREB1D</i> (nucleotides 1,489–2,250). AP2 domains from other <i>Arabidopsis</i> proteins are also included: <i>APETALA2</i> (R2 domain), <i>AtERF-1, LEAFY PETIOLE,</i> and <i>TINY</i>.</p

    application/pdfミナミハンドウイルカの保全のために必要な基礎情報を得るため,分布や移動経路の把握,地域個体群間の関係に関する検討,行動解析,繁殖生理値の収集を行った.その結果,(1)伊豆鳥島周辺に本種が分布し,その個体群は小笠原や御蔵島の個体群との間に関係を有すること,(2)奄美大島での調査により,本種が同島周辺を生活圏とすること,(3)御蔵島個体群の社会行動の分析から,その頻度が性や成長段階によって異なること,(4)飼育個体の性ホルモン分析から,オスの精子形成は春~秋により活発になることなどが明らかになった.Distribution, genetic relationship among local populations, behavior and reproductive physiology were studied for the conservation of Indo-Pacific bottlenose dolphins around Japan. In Amami Is.area where the species was first reported in Japan, more than 50 dolphins were photo-identified by boat-based surveys. A population was found around Torishima Is., Tokyo for the first time and it is genetically related to Mikura and Ogasawara populations. Frequency of social behaviors of the wild dolphins around Mikura Is.varied with sex and developmental stage. Male reproductive activity was higher in spring to fall seasons.平成19~22年度科学研究費補助金(基盤研究(B))研究成果報告書19380112research repor
