Phylogenetic relationships of Elymus L. and related genera (Poaceae) based on the nuclear ribosomal internal transcribed spacer sequences
To help in the clarification of the taxonomic status of Elymus L. and related genera Agropyron Gaertn., Leymus Hochst., Hordelymus (Jess.) Harz, and Brachypodium P.Beauv., the sequence diversity in the internal transcribed spacer (ITS) region of nuclear ribosomal DNA was studied. ITS data of 64 Triticeae accessions including 40 Elymus, 12 Agropyron, 7 Leymus, and 4 Hordelymus, and 1 Brachypodiu...
متن کاملپاسخهای مرفولوژی و فنولوژی Stipa turkestanica Melica persica و Elymus elongatus به تغییرات میکروکلیما در فصل رویش
پاسخ های مرفولوژی وفنولوژی سه گونه گندمی مرتعی Stipa turkestanica Melica persica, وElymus elongatus به کاهش رطوبت و افزایش دمای هوا و خاک زیراشکوب در طی یک فصل رویش در مراتع دهبار شهرستان بینالود بررسی شد. به فاصله هر 10-14 روز وقوع پدیده های فنولوژیکی ثبت شد. در پنج مرحله از فصل رویش، رطوبت و دمای خاک، رطوبت برگ و دمای هوا در زیر اشکوب هر سه گونه بررسی شد. دو گونه بومی M. persica و S. turk...
متن کاملFine needle cytology of complex thyroid nodules.
OBJECTIVE To evaluate whether a preliminary aspiration (ASP) of the cystic component and/or using spinal needles in complex thyroid nodules (CTN) could improve the adequacy of cytological sampling. METHODS Between January 2004 and December 2006, 386 consecutive patients with CTN were enrolled in this prospective investigation. Ultrasound (US) fine needle aspiration cytology (FNAC) of the soli...
متن کاملAllohexaploidy, introgression, and the complex phylogenetic history of Elymus repens (Poaceae).
The phylogenetic position of hexaploid Elymus repens within the tribe Triticeae (Poaceae) was examined using cloned sequences from the low-copy nuclear genes encoding phosphoenolpyruvate carboxylase (pepC) and beta-amylase. A previous analysis of E. repens using data from the nuclear granule-bound starch synthase I (GBSSI) gene had yielded five phylogenetically distinct gene copies, two more th...
متن کاملFunctional characterization of the small regulatory subunit PetP from the cytochrome b6f complex in Thermosynechococcus elongatus.
The cyanobacterial cytochrome b(6)f complex is central for the coordination of photosynthetic and respiratory electron transport and also for the balance between linear and cyclic electron transport. The development of a purification strategy for a highly active dimeric b(6)f complex from the thermophilic cyanobacterium Thermosynechococcus elongatus BP-1 enabled characterization of the structur...
