Most species of Paraphlomis are distributed in the south Yangtze River China. In this study, a new species, P. nana, from northeast Chongqing north is described and illustrated. Bayesian inference maximum likelihood analyses based on two nuclear ribosomal DNA regions (ITS ETS) three plastid markers (rpl32-trnL, rps16, trnL-trnF) were carried out to explore phylogenetic position within Paraphlom...
UNLABELLED • PREMISE OF THE STUDY The species-rich Neotropical genera Centropogon, Burmeistera, and Siphocampylus represent more than half of the ∼1200 species in the subfamily Lobelioideae (Campanulaceae). They exhibit remarkable morphological variation in floral morphology and habit. Limited taxon sampling and phylogenetic resolution, however, obscures our understanding of relationships bet...
Fission yeast cells express Rpl32-2 highly while Rpl32-1 lowly in log phase; in contrast, expression of Rpl32-1 raises and reaches a peak level while Rpl32-2 is downregulated to a low basic level when cells enter into stationary phase. Overexpression of Rpl32-1 inhibits cell growth while overexpression of Rpl32-2 does not. Deleting rpl32-2 impairs cell growth more severely than deleting rpl32-1...
The plant genus Lycium (Solanaceae) originated in the Americas and includes approximately 85 species that are distributed worldwide. The vast majority of Old World species occur in southern Africa and eastern Asia. In this study, we examine biogeographic relationships among Old World species using a phylogenetic approach coupled with molecular evolutionary analyses of the S-RNase self-incompati...
In this paper, we compare ndh genes in the plastid genome of many Cymbidium species and three closely related taxa in Orchidaceae looking for evidence of ndh gene degradation. Among the 11 ndh genes, there were frequently large deletions in directly repeated or AT-rich regions. Variation in these degraded ndh genes occurs between individual plants, apparently at population levels in these Cymbi...
جنس tanacetum l. به زیرتبار anthemidinae، تبار anthemideae از تیره asteraceae تعلق دارد. این جنس با 160 گونه، سومین جنس بزرگ تبار، بعد ازl. artemisia و anthemis l. است و عمدتاً در محدوده ناحیه مدیترانه ای، جنوب غرب، مرکز و شرق آسیا و بخش هایی از شمال آمریکا و آفریقا پراکنده است. بنابر آخرین مطالعات، تعداد گونه های ایران به 36 می رسد. در مقایسه با تنوع بالای ریخت شناسی جنس، واگرایی توالی های بکار...
Three plastid regions, matK, rpl32-trnL and rpl16 intron and the ITS1-5.8S-ITS2 nuclear ribosomal DNA were used to demonstrate a phylogenetic placement of the genus Hederorkis (Orchidaceae) for the first time. The taxonomic position of this genus has been unclear thus far. The phylogenetic and morphological relations of Hederorkis to the most closely related genera Sirhookera, Adrorhizon, Bromh...
The infrageneric phylogeny and temporal divergence of Sorghum were explored in the present study. Sequence data of two low-copy nuclear (LCN) genes, phosphoenolpyruvate carboxylase 4 (Pepc4) and granule-bound starch synthase I (GBSSI), from 79 accessions of Sorghum plus Cleistachne sorghoides together with those from outgroups were used for maximum likelihood (ML) and Bayesian inference (BI) an...
We have studied several samples from Lotus corniculatus s. l. and L. zhegulensis populations with the use of SSR sequenced nuclear (ITS) plastid (atpB-rbcL, ndhC-trnV, rpl32-trnL(UAG), trnH-psbA, trnL-trnF) markers. analysed 9 local Volga River valley ranging Ulyanovsk in north to Volgograd south, as well two Moscow Lipetsk Provinces. Analyses markers using STRUCRURE program divided sample into...
Biscutella raphanifolia is a species distributed in N Algeria and Tunisia, characterized by the presence of large, lyrate basal leaves, amplexicaul cauline leaves, and paniculate-branched inflorescences. It has been traditionally considered the only perennial taxon from B. sect. Biscutella, lifespan being the strongest argument used to differentiate B. raphanifolia from other annual taxa such a...
