The study aimed to evaluate the occurrence of pest and management of cotton genetically modified with the introduction of the bacterium Bacillus thunringiensis compared to conventional cotton in the 'Cerrado' region, installing the field experiment in 2007/2008 in Chapadão do Sul-MS. The experimental design was randomized blocks in a 2 × 3 factorial, with two managements of insecticides (with and without insecticides to control lepidopteran) and 3 modes of use of cultivars: 100% transgenic (NUOPAL), 100% non transgenic (Deltaopal) and interior area with transgenic (80% NUOPAL) with non-transgenic border (20% Deltaopal) with five replications. Evaluations were performed weekly of pest infestation, observing in 15 plants per plot the number of Alabama argillacea, Heliothis virescens and Spodoptera frugiperda. Based on these results it was concluded that: the occurrence of A. argillacea and H. virescens was lower in treated transgenic cultivar. There were no differences between transgenic and conventional farming on the occurrence of S. frugiperda.

Hereditary myotonia caused by mutations in CLCN1 has been previously described in humans, goats, dogs, mice and horses. The goal of this study was to characterize the clinical, morphological and genetic features of hereditary myotonia in Murrah buffalo. Clinical and laboratory evaluations were performed on affected and normal animals. CLCN1 cDNA and the relevant genomic region from normal and affected animals were sequenced. The affected animals exhibited muscle hypertrophy and stiffness. Myotonic discharges were observed during EMG, and dystrophic changes were not present in skeletal muscle biopsies; the last 43 nucleotides of exon-3 of the CLCN1 mRNA were deleted. Cloning of the genomic fragment revealed that the exclusion of this exonic sequence was caused by aberrant splicing, which was associated with the presence of a synonymous SNP in exon-3 (c.396C>T). The mutant allele triggered the efficient use of an ectopic 5' splice donor site located at nucleotides 90-91 of exon-3. The predicted impact of this aberrant splicing event is the alteration of the CLCN1 translational reading frame, which results in the incorporation of 24 unrelated amino acids followed by a premature stop codon.
