Fig (Ficus carica L.) is a fruit of great importance worldwide. Its propagation is carried out with stem cuttings, a procedure that favors the occurrence of synonymy among specimens. Thus, molecular markers have become an important tool for studies of DNA fingerprinting, germplasm characterization, and genetic diversity evaluation in this plant species. The aim of this study was ... more
The bovine prolactin (PRL) and bovine growth hormone (bGH) genes exhibit several polymorphisms. Some of them can be detected by molecular techniques using restriction endonucleases, such as RsaI for the PRL gene and MspI for the bGH gene. We examined the relationship between the PRL-RsaI and bGH-MspI polymorphisms and ... more
We developed six microsatellite markers for the fall armyworm Spodoptera frugiperda (Lepidoptera: Noctuidae). The SSR loci were isolated with enriched genomic library protocol by using native individuals as a genome source for markers. These loci were characterized in 48 individuals and they were tested for the ability to identify candidate migrants exchanged among the samples. ... more
Outside its centers of origin, garlic propagates only asexually. Since asexual reproduction leads to the absence of meiotic recombination, the main garlic cultivars available for cultivation have arisen from the accumulation of somatic mutations in early cultivars. Thus, it is common for a single clone to have different names in different regions. This study aimed to evaluate the genetic ... more
The increasing number of protected and registered cultivars and problems involving seed commercialization make distinction and identification of cultivars imperative. Millet (Pennisetum glaucum), a crop species with protected cultivars in Brazil, has been the target of seed piracy. Thus, with the objective of identifying different lots with regard to origin, we characterized six ... more
The silverleaf whitefly (Bemisia tabaci) is actually a complex of morphologically indistinct species that vary in their capacity to transmit plant viruses and to induce physiological disorders in plants of economic importance. The worldwide impact of this whitefly has increased greatly, as it is a vector of various types of phytovirus, especially geminiviruses, in plants of ... more
Given the important role of leptin in metabolism, we looked for a possible association of leptin and leptin receptor polymorphisms with carcass and growth traits in Nellore cattle. We examined associations of leptin and leptin receptor SNPs with ultrasound carcass (longissimus dorsi muscle area (ribeye area), backfat thickness and rump fat thickness and growth traits (weaning weight ... more
Leaf rust is one of the most destructive diseases affecting wheat worldwide. The most effective way to control it is to use resistant cultivars. Resistance based on slow-rusting adult plant resistance (APR) genes has proven to be the best method for developing cultivars with durable resistance. A source of slow-rusting APR for leaf rust is the Brazilian wheat cultivar Toropi. The Toropi/ ... more
Farming of Haliotis midae is the most lucrative aquaculture venture in South Africa. The genome of this species needs to be studied to assist in selective breeding programs aimed at increasing overall yield, and molecular markers will be required to attain this goal. We identified and characterized 82 polymorphic microsatellite loci by using repeat-enriched genomic libraries and ... more
Identification and knowledge concerning genetic diversity are fundamental for efficient management and use of grapevine germplasm. Recently, new types of molecular markers have been developed, such as retrotransposon-based markers. Because of their multilocus pattern, retrotransposon-based markers might be able to differentiate grapevine accessions with just one pair of primers. In order ... more
