A Brazilian strain of Bacillus thuringiensis subsp. kurstaki, designated S93, was analyzed regarding its cry gene and protein contents and activity against the fall armyworm (Spodoptera frugiperda, Smith 1797). Bioassays using lyophilized powders of S93 or HD-l and third instar larvae of S. frugiperda showed a 12.3-fold lower LCso for the S93 strain when compared with the standard HD-l strain. The spore-crystal mixture, analyzed by SDS-PAGE, showed two major polypeptides of 130 and 65 kDa, corresponding to Cryl and Cry2 toxins, respectively. Western blot analysis showed that these proteins were immunologically related to the CrylA protein from B. thuringiensis subsp. kurstaki HD-73. The polymerase chain reaction technique (PCR) using total DNA from the S93 strain and specific primers showed the presence of crylAa, crylAb, and crylAc genes, and a crylA-type gene was localized in a plasmid of about 44 MDa. A cry lAb gene was isolated from a S93 plasmid DNA library and completely sequenced. Computer analysis showed that the gene sequence (GenBank acession number AF059670) is identical to crylAbl and has 91.6 and 85.9% identity with crylAal and crylAcl genes, respectively. The deduced amino-acid sequence showed a high degree of similarity with the amino-acid sequences of the Cry lAb 1 (100%), CrylAal (93.8%), and CrylAcl (90.6%) proteins.

frugiperda, Smith, 1797). Les bioessais utilisant des poudres lyophilisees de S93 ou de HD-l et des larves du troisieme age de S. frugiperda ont montre une LCso 12.3 fois plus basse pour la souche S93 comparativement a la souche standard HD-1. Le melange spores-cristaux, analyse par SDS-PAGE, a revele deux polypeptides principaux de 130 et 65 kDa, correspondant aux toxines Cry 1 et Cry2 respectivement. Le buvardage Western a confirme que ces proteines etaient immunologiquement apparentees ala proteine CrylA de B. thuringiensis subsp. kurstaki HD-73. La reaction en chaine de la polymerase (PCR) utilisant l' ADN total de la souche S93 et des amorces specifiques a confirme la presence des genes cryJAa, cryJAb, et cryJAc et a permis de reperer un gene de type cryJA sur un plasmide ca. 44 Mda. Un gene cryJAb a ete isole d'une banque d'ADN plasmidique S93 et iI a ete completement sequence. Une analyse informatisee a montre que la sequence de ce gene (code d'identification GenBank AF059670) etait identique a celle de cryJAbJ et qu'elle etait a 91.6% et 85.9% identique a celle des genes cryJAaJ et cryJAcl respectivement.

Sugarcane is an important crop, major source of sugar and alcohol, accounting for two-thirds of the world's sugar production. In Brazil, the sugarcane culture has expanded to areas with prolonged drought seasons, which is constraining its production. In order to identify genes and molecular process related to sugarcane drought tolerance, we performed de novo assembly and transcriptome analysis of two sugarcane genotypes, one tolerant and other sensitive to water stress, submitted to three water deficit condition (30, 60 and 90 days). The de novo assembly of leaves transcriptome was performed using short reads from Illumina RNA-Seq platform, which produced more than 1 billion reads, which were assembled into 177,509 and 185,153 transcripts sequences for the tolerant and sensitive cultivars, respectively. These transcripts were aligned with Sorghum bicolor, Miscanthus giganteus, Arabidopsis thaliana sequences and sugarcane sequences available in public databases. This analysis allowed the identification of a set of sugarcane genes shared with other species, as well as led to the identification of novel transcripts not cataloged yet. Differential expression analysis between genotypes and among days of water deficit were performed with EdgeR and DESeq. The differentially expressed genes were annotated and categorized using Blast2GO. The terms "enzyme regulator" and "transcription regulator" were highlighted within the differentially expressed genes between the contrasting cultivars, suggesting the importance of gene regulation during water deficit. This study found new molecular patterns, which provided hypotheses on plant response to drought and provided important information about genes involved in drought tolerance response.
