Ricinus communis (castor bean) seeds are used to produce an alcohol-soluble oil that is used in more than 400 industrial processes. Despite its economic importance, there has been little research on the endophytic microbiota of castor bean seeds. This microbiota is important for plant metabolic processes and may have considerable biotechnological potential, such as production of ... more

Four Hyriopsis cumingii populations, a breeding population (BP), a cultured population (FP), two wild populations from Poyang Lake (PY) and Dongting Lake (DT), and an H. schlegelii population were collected (JX), and the first filial generations (F1) were bred synchronously. The shell nacre polymorphisms, population genetic diversity, and genetic structures of the F1 of each population were ... more

Nuclear mitochondrial pseudogenes (numts), originating from mtDNA insertions into the nuclear genome, have been detected in many species. However, the distribution of numts in the newly published nuclear genome of domestic goat (Capra hircus) has not yet been explored. We used the entire goat mtDNA sequence and nuclear genome, to identify 118 numts using BLAST. Of these, 79 were able to map ... more

Genetic variability is one of the important criteria for species conservation decisions. This study aimed to analyze the genetic diversity and the population differentiation of two natural populations of Arapaima gigas, a species with a long history of being commercially exploited. We collected 87 samples of A. gigas from Grande Curuai Lake and Paru Lake, located in the Lower Amazon region of ... more

Guava (Psidium guajava L.) crop is severely affected by the nematode Meloidogyne enterolobii. Native Psidium species have been reported as sources of resistance against this nematode. Knowledge on the molecular relationship between Psidium species based on plant resistance gene analogs (RGA) can be useful in the genetic breeding of guava for resistance to M. enterolobii. In this study, RGA ... more

We used the conventional and methylation-sensitive randomly amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analyses to assess genome-wide changes and explore the relationships between genetic and epigenetic variations among individuals of a newly synthesized allohexaploid wheat line whose genomic constitution is identical to that of the natural common wheat, compared ... more

Bovine coronavirus (BCoV) is a pathogen related to enteric and respiratory diseases in cattle worldwide. Enteric (BECoV) strains of BCoV are predominant in South America, and genetic investigations have been conducted to identify its relationship with isolates of respiratory origin (BRCoV). In this study, we used a BRCoV strain (BR-UEL11) derived from an outbreak of respiratory disease in ... more

Sphyraena (barracudas) represents the only genus of the Sphyraenidae family and includes 27 species distributed into the tropical and subtropical oceanic regions. These pelagic predators can reach large sizes and, thus, attracting significant interest from commercial and sport fishing. Evolutionary data for this fish group, as well its chromosomal patterns, are very incipient. In the present ... more

The aim of this study was to investigate the tumor protein p73 (TP73) G4C14-A4T14 polymorphism and to perform a meta-analysis to assess TP73 expression in cervical cancer and precancerous tissue. Articles containing data regarding TP73 status in cervical cancer patients and healthy controls were retrieved from PubMed, EMBASE, Cochrane, Chinese Biomedical Literature, and China National ... more

Cajazeira (Spondias mombin L.), of the family Anacardiaceae, is a species of fruit tree found in the Amazon region with fruits that have excellent prospects for commercial use. We aimed to evaluate the genetic diversity within and among natural populations of S. mombin, with natural occurrence in northern Mato Grosso State, by using inter-simple sequence repeat (ISSR) markers. Overall, 126 ... more
