Phylogenetic analysis of MADS-box genes in gymnosperms
Phylogenetic 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 ...

DNA metabarcoding reveals key floral resources for native pollinators in post‐fire landscapes
Ecological Applications, Volume 36, Issue 7, October 2026.Abstract Wildfires are a natural disturbance in dry ponderosa pine forest ecosystems, and are increasing in frequency and severity across western North America. The effects of wildfire on biotic and abiotic conditions have important implications for higher trophic levels, including native bees. We sought to quantify the responses of flowering plants to

Ecology and Evolution, Volume 16, Issue 10, October 2026.We report the first discovery of wild double‐flowered populations of the alpine dwarf shrub Rhododendron nivale on the eastern Qinghai‐Tibet Plateau. Two geographically isolated populations (> 800 km apart) show nearly identical stamen petaloidy and floral modifications in similar harsh high‐altitude habitats, suggesting possible parallel evolution ...

Characterisation of oil palm (Elaeis guineensis Jacq.) mads box genes [S20-48]
, 2003 MADS box genes encode a highly conserved family of transcription factors of which many are involved in the control of flowering. MADS box genes may act at a number of different developmental stages, from the initiation of the inflorescence meristem to ...

Environmetrics, Volume 37, Issue 7, October 2026.ABSTRACT Spatial boundaries, such as ecological transitions or climatic regime interfaces, capture steep environmental gradients, and shifts in their structure can signal emerging environmental changes. Quantifying uncertainty in spatial boundary locations and formally testing for temporal shifts remain challenging, especially when boundaries are ...
