Molecular characterization of eleven clones of C. winterianus collected from eleven districts of West Bengal was carried out with 10 RAPD and 9 ISSR primers. The RAPD primers developed 81 robust loci, which revealed 74.07% polymorphism and 61 ISSR markers generated 47.50% polymorphism. Out of the different anchored primer combinations, ISSR primers with AG and GA motifs produced clear and maxim...

Lasia spinosa or Unicorn plant is an important tropical spinous rhizomatous herb. This one of the native species Assam used as vegetable and in Ayurvedic medicines. There are two distinct morphological types spinosa: Morphotype-I i.e.having dissected laminal hastate form Morphotype- II i.e. form. The current study revealed that physical anatomical parameters assent with genetic diversity throug...

Costus pictus, belonging to the family Costaceae, is one of the valuable medicinal plants with its anti-diabetic property. Despite ever-increasing demand from the pharmaceutical industry, this species is being less exploited at molecular level. Hence, an effort has been made in the present study to characterize the 15 accessions of C. pictus collected from different geographical regions of Indi...

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 ...

Pseudoplatystoma corruscans (Spix and Agassiz, 1829) and Pseudoplatystoma reticulatum (Eingenmann and Eigenmann, 1889) are large migratory catfishes of high biological importance and great commercial value in South America. Because fertile crossbreeds can be artificially produced in hatcheries, a high genetic proximity between these two Pimelodidae species is conceivable. Possible escape of cro...

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...
