Two new species, Machilus bokorensis Yahara & Tagane and Machilus brevipaniculata Yahara & Tagane (Lauraceae) are described from Bokor National Park, Cambodia with their illustrations and DNA barcodes of the two plastid regions of rbcL and matK and the nuclear region of ITS.
A sensitive qualitative detection method for walnut (Juglans regia) using polymerase chain reaction (PCR) was developed. For detection of walnuts with high specificity, the primer pair WAL-F/WAL-R was designed based on walnut matK genes. Trace amounts of walnuts in commercial food products can be qualitatively detected using this method.
The current tribal classification of Myrtaceae was based on analysis the plastid matK coding region within trnK intron. phylogenetic position genera Cloezia and Xanthomyrtus poorly supported, original sequence for Kania, type genus tribe Kanieae, rather poor. To clarify relationships, we sequenced psbA–trnH an extended portion intron, including spacer regions flanking matK, nuclear ribosomal IT...
عناب (zizyphus jujuba mill.) یکی از گیاهان باغی مهم با گونه ها و واریته های متنوع در منطقه آسیای مرکزی و غربی است که در بسیاری از مناطق و استان های ایران پراکنش طبیعی دارد. این تحقیق با هدف بررسی تنوع ژنتیکی و ژنومی با استفاده از صفات کمی و مارکرهای مولکولی issr و rapd در کلکسیون عناب ایران، شامل نمونه های جمع آوری شده از هشت استان، در استان خراسان جنوبی انجام شد. تنوع قابل ملاحظه ای در میان 29...
Cytokinins (CTKs) regulate panicle size and mediate heat tolerance in crops. To investigate the effect of high temperature on panicle CTK expression and the role of such expression in panicle differentiation in rice, four rice varieties (Nagina22, N22; Huanghuazhan, HHZ; Liangyoupeijiu, LYPJ; and Shanyou63, SY63) were grown under normal conditions and subjected to three high temperature treatme...
T he goal of DNA barcoding is conceptually simple: Find one or a few regions of DNA that will distinguish among the majority of the world’s species, and sequence these from diverse sample sets to produce a large-scale reference library of life on earth (1). This approach can then be used as a tool for species identification and to help in the discovery of new species (2). Since the first DNA ba...
Lithocarpus vuquangensis Ngoc & Hung is described from Vu Quang National Park, North Central Vietnam. The morphological comparison and phylogenetic analysis based on rbcL, matK and ITS provided evidence that the new species was not assignable to any of the previously known taxa in Vietnam and its surrounding countries. The description, photographs, preliminary conservation status and DNA barcod...
