Chromosomes of Cnemidophorus littoralis, a new species of teiid lizard recently described, were studied. The animals are from a restinga area in Barra de Maricá, RJ. The karyotype presents a diploid number of 2n = 46 chromosomes and a chromosomal sex determination mechanism of the type XX:XY. Nucleolar organizer regions, Ag-NORs, are at the sixth pair of chromosomes; there is variability of siz...

The genus Amphichorda has been recently re-erected as an independent lineage from Beauveria, circumscribed within Cordycipitaceae. However, its phylogenetic relationships with other members of this family remain obscure. In our ongoing efforts to expand the knowledge on diversity culturable ascomycetes Mediterranean Sea, we isolated several specimens Amphichorda. Preliminary sequence analyses r...

Cotton leaf worm, Spodoptera littoralis, is considered one of the most common arthropod pests that contribute to crop devastation cotton. Previously, agricultural were controlled through application chemical insecticides. However, insecticide-resistant insect populations emergence, as well increasing concerns about environmental and human health risks. Venomous animals introduce valuable source...

dna methylation as epigenetic mark plays a key role in normal differential and developmental processes as well as in dynamic gene regulation at the genomic level. to assess dna methylation pattern in different developmental stages of aeluropus littoralis, methylation sensitive amplified polymorphism (msap) was used. methylation and demethylation status at the ccgg recognition site were tracked ...

Abstract Background Mass rearing cost of Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) is one the critical methods for successful utilization Baculovirus pathogenicity and sterile insect technique (SIT). Effectiveness both SIT S. Nucleopolyhedrosis Virus ( Spli NPV) was assessed in response to plant-based diet substitution agar with commercial sources gelling components as feed. Resul...

background: we describe karyotypic variations and the in vitro methods for plant propagation and conservation as well as detailed chromosomal analysis of (aloe vera l.) and aloe littoralis from iran during flowering stage. objectives: this karyotypic was discovered because of a difference in the position of the chromosome and due to genomic differentiation in domesticated populations of the ira...

EPR spectroscopy was used to investigate the cytochrome P-450-dependent steroid hydroxylase ecdysone 20-mono-oxygenase of the cotton leafworm (Spodoptera littoralis) and the redox centres associated with membranes from the fat-body mitochondrial fraction. Intense features at g = 2.42, 2.25 and 1.92 from oxidized mitochondrial membranes have been assigned to the low-spin haem form of ferricytoch...
