Microsatellite markers for population studies of the salt marsh species Juncus roemerianus (Juncaceae)1
PREMISE OF THE STUDY Juncus roemerianus (Juncaceae) is a foundational species and ecosystem engineer of salt marshes in the Gulf of Mexico. These ecosystems provide coastal flood attenuation, nurseries for important species, and other ecosystem services, but are experiencing significant decline. Nuclear microsatellite markers were developed for J. roemerianus to study genetic diversity and popu...
متن کاملSynchronous pulsed flowering: analysis of the flowering phenology in Juncus (Juncaceae).
BACKGROUND AND AIMS The timing of flowering within and among individuals is of fundamental biological importance because of its influence on total seed production and, ultimately, fitness. Traditional descriptive parameters of flowering phenology focus on onset and duration of flowering and on synchrony among individuals. These parameters do not adequately account for variability in flowering a...
متن کاملبررسی بیوسیستماتیکی جنس juncus l. (juncaceae) در شمال شرق ایران
چکیده جنس juncus l. از تیره juncaceae شامل حدود 315 گونه است و از نظر پراکنش دارای انتشار جهانی است. در فلورا ایرانیکا از این جنس 28 گونه نام برده شده است که 20 گونه از آن در نقاط مختلف ایران پراکنش دارد و از این تعداد 9 گونه از ناحیه شمال شرق ایران گزارش شده است. بررسی منابع نشان می دهد که تاکنون پژوهش های اندکی در مورد ریخت شناسی، ساختار تشریحی، گرده شناسی و بذر گونه های این جنس در جهان صورت...
15 صفحه اولCircumpolar phylogeography of Juncus biglumis (Juncaceae) inferred from AFLP fingerprints, cpDNA sequences, nuclear DNA content and chromosome numbers.
We explored the circumpolar phylogeographic history of the arctic-alpine Juncus biglumis using amplified fragment length polymorphisms (AFLPs), sequences of cpDNA, relative nuclear DNA content and chromosome numbers. The analyses of the AFLP and cpDNA data gave congruent results and revealed three distinct clades. One of them, represented by a single population from the Taymyr peninsula in nort...
متن کاملJuncus quartinianus (Juncaceae, sect. Ozophyllum): A Neglected Species from the Horn of Africa and Its Re-Description Based on Morphological SEM Studies
Juncus quartinianus (Juncaceae sect. Ozophyllum) was described by Richard in 1851 from Ethiopia. Some authors have treated this species as a synonym of J. fontanesii and others as a synonym of J. oxycarpus. Based on morphological analyses of flowers, fruit and seeds, we propose to restore J. quartinianus as a distinct species from both these taxa. Its detailed re-description and an identificati...
