Curcuma wenyujin is an important multifunctional medicinal herb in China. Currently, populations of C. wenyujin are decreasing, and wild individuals have almost disappeared from their natural habitats. Moreover, little is known regarding the molecular characteristics of this plant. In this study, we investigated the genetic diversity and variation of five populations of C. wenyujin, using ran-d...

Genetic diversity and differentiation of 50 Colletotrichum spp. isolates from legume crops studied through multigene loci, RAPD and ISSR analysis. DNA sequence comparisons by six genes (ITS, ACT, Tub2, CHS-1, GAPDH, and HIS3) verified species identity of C. truncatum, C. dematium and C. gloeosporiodes and identity C. capsici as a synonym of C. truncatum. Based on the matrix distance analysis of...

The recently developed Inter-Simple Sequence Repeat PCR (ISSR-PCR) or microsatellite primed PCR or Simple Sequence Repeat (SSR)-Anchored PCR technique detects polymorphic markers in a wide variety of genomes. Usually the ISSR primers are either 5' end-labeled with gamma[32P]ATP or one of the alpha[32P] labeled dNTPs is added to the PCR reaction and the PCR products are resolved on PAGE and auto...

In this study Artemisia amygdalina a critically endangered medicinal plant endemic to Kashmir Himalayas was grown under in vitro conditions. ISSR markers were used to study the somaclonal variation at the genetic level. Two ISSR-primers (CAC)3 GC and (ACTG)5 were used, two additional DNA bands (0.15kb and 0.2kb) were observed respectively in tissue cultured Artemisia amygdalina. Direct regenera...

The work involved a molecular biological technique (ISSR-PCR) using ISSR-primer S-2, with structure (AGC) 6G. Changes in the gastric mucosa chronic duodenal ulcer disease against background of severe atrophic gastritis have been analyzed. Noteworthy is fact that there strong correlation between degree dysplasia epithelium and mitotic index, Pearson's coefficient rxy was 0.853, respectively. A v...

In this dataset, we present 15 Simple Sequence Repeat (SSR) markers with the motifs (AC)n, (GA)n, and (AC)n(AG)n using a ISSR-Suppression-PCR technique in order to discriminate Garcinia mangostana from diverse geographical origins in Peninsular Malaysia. A few loci showed differences between 3 and 6 bp in allele size, indicating that there are some polymorphisms between individuals correlating ...

Sequence-related amplified polymorphism (SRAP), amplified fragment length polymorphism (AFLP), and inter-simple sequence repeat (ISSR) markers were used to estimate the genetic diversity and relationships among Eucommia ulmoides cultivars in China. A total of 240, 192, and 150 DNA fragments were detected by 10 SRAP primer combinations, 10 AFLP primer combinations, and 10 ISSR primers, among whi...

Random amplified polymorphic DNA polymerase chain reaction (RAPD-PCR) and inter simple sequence repeats (ISSRs) markers were performed to detect the genetic diversity among 6 new rice lines and 4 cultivars with different responses to drought tolerance and establish specific DNA markers associated with drought tolerance. Among 16 RAPD primers tested, only 5 produced bands polymorphic between lin...

Blumeria graminis f. sp. tritici, which causes wheat powdery mildew, is an obligate biotrophic pathogen that can easily genetically adapt to its host plant. Understanding the virulence structure of and genetic variations in this pathogen is essential for disease control and for breeding resistance to wheat powdery mildew. This study investigated 17 pathogenic populations in Sichuan, China and c...
