Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of ten experimental materials in Rehmannia glutinosa Libosch .f. hueichingensis (Chao et Schih) Hsiao, including eight cultivars and two virus-free lines micropropagated by tip tissue culture from Wenxian county. A high level of polymor...

Jatropha curcas L. is a rapidly emerging biofuel crop attracting a lot of interest, triggering large investments and rapid expansion of cultivation areas. In the present investigation, the genetic relationships of 29 J. curcas accessions were assessed based on randomly amplified polymorphic DNA (RAPD) and inter simple sequence repeat (ISSR) analyses. A total of 72 polymorphic primers (47 RAPD a...

The genetic diversity in Zanthoxylum species viz.  Zanthoxylum nitidum, Zanthoxylum oxyphyllum and Zanthoxylum rhesta collected from the Upper Brahmaputra Valley Zone of Assam (NE India) was amplified using 13 random amplified polymorphic DNA (RAPD) markers and 9 inter-simple sequence repeat (ISSR) markers. RAPD markers were able to detect 81.82% polymorphism whereas ISSR detected 98.02% polymo...

Twelve species belonging to six fungal genera were found to be associated with wheat (Triticum aestivum L.) grain samples collected from three main regions in Saudi Arabia. The most common genera (average frequency) were Aspergillus (14.3%), Fusarium (29.1%), Penicillium (9.3%), and Alternaria (8.2%). Nineteen isolates of Aspergillus flavus were screened for their ability to produce aflatoxins ...

There is a lack of information on the molecular characterization of Ocimum species and hence, efforts have been made under the present study to characterize 17 Ocimum genotypes belonging to 5 different species (O. basilicum, O. americanum, O. sanctum, O. gratissimum and O. Polystachyon) through random amplified polymorphic DNA (RAPD) and inter simple sequence repeats (ISSR) markers. PCR amplifi...

Karnal bunt of wheat, caused by Tilletia indica Mitra is an important disease prevalent in several countries. The pathogen due to its heterothallic nature shows high variability. In the present study, genetic relationships among ten isolates of T.indica collected from different locations of India and 15 monosporidial lines raised from these isolates were investigated by using 34 RAPD and 28 ISS...

Chlorophytum borivilianum is a traditional medicinal plant distributed throughout the trop‐ ics and subtropics. In the present investigation, RAPD and ISSR analyses were used to assess the genetic diversity among 21 accessions collected from different geographical regions of India using 20 RAPD primers and 6 ISSR primers. RAPD and ISSR primers revealed 92.26% and 82.76% polymorphism, respective...
