Phylogenetic analysis of MADS-box genes in gymnosperms

open access: yesPhylogenetic analysis of MADS-box genes in gymnosperms
被子植物においては花器官形成に関わるMADS-box遺伝子群が知られている。本研究は裸子植物における雌雄の器官形成の進化を知ることを目的とし,MADS-box遺伝子の部分配列を決定し,系統解析を行った。対象植物は,裸子植物であるイチョウ,グネツム,マオウ,ソテツ,エゾマツ,ドイツトウヒ,イチイ,スギ,メタセコイア,およびシダ植物であるヒメワラビの計10種であった。実験手法は,裸子植物(イチョウ,グネツム,トウヒ,スギ)で既に知られているMADS-box遺伝子の保存領域からデジェネレートプライマーを設計し,10種の葉から抽出したDNAをテンプレートとして計91組のプライマー対でPCRを行った。増幅されたDNA断片はクローニング後選抜し,塩基配列を決定した。その結果,イチョウ,ソテツ ...

Human Recreation and Fire History Shape Landscape Connectivity for an Endangered Forest Carnivore

open access: yesAnimal Conservation, EarlyView.
Roads and trails can impede wildlife movement, but their permeability varies with human use and fire history. We combined GPS telemetry from 45 endangered southern Sierra Nevada fishers (Pekania pennanti) with smartphone‐derived human mobility data to estimate crossing probability across road and trail segments. Fishers were about 2.5 times more likely
