Genetic diversity of 20 sugarcane accessions in Pakistan was studied using 21 random amplified polymorphic DNA markers. The mean genetic distance between the cultivars was 39.03%, demonstrating that a large part of the genome is similar among the accessions. This probably arises from a lack of parental diversity, with few clones, which are themselves related, contributing to the parentage ... more
Prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of Coruh Valley in the northeastern part of Turkey; the fruit is used to make preserves. We examined genetic diversity in wild-grown Prunus spinosa; 16 individual plants from wild populations of Coruh Valley were sampled and subjected to RAPD (random amplified polymorphic DNA) ... more
The fig tree (Ficus carica L.) is of significant socio-economic importance in Turkey, with 25% of the world’s fig production. Genetic variation and relationships among 14 wild-grown figs sampled from Coruh Valley in Turkey were characterized by random amplified polymorphic DNA (RAPD). Ninety-eight DNA fragments were scored after amplification of DNA samples with 13 random primers ... more
Two local (Vezir-1 and Vezir-2) and two standard (M9 and MM106) clonal apple rootstocks were compared using both morphological and molecular markers. International Union for the Protection of New Varieties of Plants criteria were used for morphological evaluation, which did not clearly separate these rootstocks. We tested 47 random decamer primers for random amplified polymorphic DNA analysis ... more
The silkworm Bombyx mori L. is particularly susceptible to virus diseases, especially B. mori nucleopolyhedrovirus (BmNPV). Disease resistance, along with high productivity, are important selection criteria for developing commercial hybrids of B. mori. We used bioassays and molecular markers linked to susceptibility/resistance to baculovirus infection to analyze the ... more
Catuaba (Anemopaegma arvense), a Bignoniaceae species endemic to Cerrado regions, shows anticancer properties and is widely used as a stimulant in traditional medicine. We evaluated the genetic diversity of seven populations found in the State of São Paulo, using random amplified polymorphic DNA markers. After optimization of the amplification reaction, 10 selected primers produced 70 ... more
The genetic diversity among eight sunflower lines was determined through the estimation of the random amplified polymorphic DNA method. One hundred and fifty-six DNA fragments were generated by 20 random primers, for an average of about 7.8 bands per primer. Of these amplified DNA fragments, 104 were polymorphic among the eight sunflower lines. Nei and Li’s similarity matrix gave values from ... more
The random amplified polymorphic DNA (RAPD) technique is often criticized because it usually shows low levels of repeatability; thus it can generate spurious bands. These problems can be partially overcome by rigid laboratory protocols and by performing repeatability tests. However, because it is expensive and time-consuming to obtain genetic data twice for all individuals, a few randomly ... more
The Aspergillus genus belongs to a filamentous fungal group characterized by wide dispersion in the environment. Some species are associated with diseases, especially in immunocompromised patients, while others are of economical importance due to aflatoxin production or biotechnological applications. Its species identification is nowadays performed by traditional techniques combined ... more
The garlic cultivars grown in Brazil evolved from somatic mutations and clone selection by breeding programs and by the introduction of germplasm from other countries. Morphological characters have been used to differentiate these cultivars. Two hundred and six random amplified polymorphic DNA markers were utilized for a diversity analysis of the 17 most planted garlic cultivars in Brazil. ... more
