Morphologically, nine different slow-growing protoclones were screened from regenerated protoplast of heterokaryotic Agaricus bisporus. The present study is the first report of fingerprinting on differentiating homo- and heterokaryotic protoclones using random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) markers. Among 80 primers tested, the seven ISSR and seven RAPD...

We expanded the basic ISSR-PCR protocol by an additional PCR reamplification round in order to detect whether increased PCR productivity would give new bands in ISSR patterns. We found that the reamplification step had a prominent impact on the quality of the inter-simple-sequence repeat (ISSR) PCR patterns of flax, depending on the particular primer used for PCR amplification. We could clearly...

In the present study, 20 sandalwood (Santalum album L.) genotypes were characterized using RAPD, ISSR and SSR markers. Twenty-five RAPD and twenty-one ISSR primers that generated clear and reproducible banding patterns amplified 225 and 208 bands, respectively, among 20 sandalwood genotypes. Out of 225, 181 (83.13 %) RAPD bands were polymorphic while out of 208, 156 (75.77 %) ISSR bands were po...

Sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers were used to assess the genetic diversity within and among 15 natural populations of Stipa bungeana from the Loess Plateau of China. Using 15 SRAP primers, 504 (99.80%) polymorphic loci were detected, and 372 polymorphic loci (96.12%) were identified using 15 ISSR primers. At the species level, the S....

Kumar A, Verma N. 2012. A comparative phylogenetic analysis of medicinal plant Tribulus terrestris in Northwest India revealed by RAPD and ISSR markers. Biodiversitas 13: 107-113. Several DNA marker systems and associated techniques are available today for fingerprinting of plant varieties. A total of 5 RAPD and 8 ISSR primers were used. Amplification of genomic DNA of the 6 genotypes, using RA...

Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of 46 barley accessions, including 27 landraces of H. vulgare ssp vulgare (HV), 6 accessions of H. vulgare ssp. spontaneum (HS) and 13 accessions of H. vulgare ssp. agriocrithon (HA), from west China. A high level of polymorphism was fo...

Cotton is one of the most economically important crops in Iran; hybridization is a means to increase the genetic diversity and obtain new elite cultivars in this crop. We examined agronomic characteristics and molecular genetic diversity in the Opal cotton (Gossypium hirsutum) cultivar and in F(2) progenies. Ten homo-primers and seven hetero-primers of 26 RAPD primers produced 261 reproduc...

We studied the applicability of intersimple sequence repeat (ISSR) polymorphism in cotton. We found that: (i) the resolving power of agarose gels is poor relative to that provided by sequencing gels; (ii) fluorescent labelling of ISSR amplification primers produced numerous scorable bands; (iii) primer mixing (double priming) generated more bands than the sum of fragments resulting from two sin...

Fusarium Head Blight is an important wheat disease in the Argentine Pampas region, being Fusarium graminearum the predominant pathogen. DNA polymorphism of the isolates was analyzed by IGS-RFLP and ISSR. IGS-RFLP and ISSR profiling were carried out using six endonucleases and eight primers, respectively. IGS-RFLP yielded 41 bands, 30 of which were polymorphic while ISSR produced 87 bands with 4...
