The objective of this work was to evaluate the genetic diversity of 16 maize inbred lines, and to determine the correlation between genetic distance and hybrid performance, using random amplified polymorphic DNA (RAPD) molecular markers. Twenty-two different random primers were used, which resulted in the amplification of 265 fragments, 237 (84.44%) of them being polymorphic. A genetic similarity matrix was created from the RAPD data, using Jaccard coefficient, and a dendrogram was constructed. Hybrid analyses were carried out using random block design and Griffing method VI for diallel crossings. The genetic associations showed five distinct heterotic groups. Correlations between genetic divergences detected by RAPD, as well as the means observed in the diallel crossings were positive and significant for plant height, ear height, prolificacy, and grain weight. The correlation of genetic divergences, detected by RAPD, and the specific combining ability between heterotic group associations, showed significance in all characteristics under study, except prolificacy. A direct relationship between genetic divergence and productivity was found in 79.2% of the 120 hybrids confirming the hypothesis that genetic divergence is directly related to the performance of hybrids and is efficient in predicting it. |

The fungus Metarhizium rileyi (= Nomuraea rileyi) is a key regulatory agent of lepidopteran populations. In soybean and cotton agroecosystems, it causes major epizootics decimating important lepidopteran pests such as velvetbean caterpillar, soybean loopers, green cloverworm, cotton leafworm and others. Despite its recent phylogenetic transfer to Metarhizium, M. rileyi displays unusually high specificity by infecting only lepidopteran species. The complete genome of M. rileyi was assembled de novo using short-read Illumina data from paired-end and mate- pair libraries. A total of 311 scaffolds were constructed (> 1 kb, N50 = 800 kb), with a total length of 31,007,635 bp. An ab initio annotation, using a set of 2,159 gene stuctures of Metarhizium robertsii ARSEF 23 to train the model, predicted a total of 10,880 genes coding for proteins in this genome. Orthologous genes were detected in M. robertsii and M. acridum: 4,806 orthologs in both species, 349 orthologs only in M. robertsii, and 301 orthologs only in M. acridum. In-paralogs were not counted. Divergent genes (4,534) with no shared orthologs were compared to annotation data for known functions and were categorized according to an enrichment analysis of function-related aspects. A remarkable and more numerous category of genes appears to be polyketide synthases, possibly involved in the secondary metabolism required for virulence to insect hosts. This study provides the genome sequence and annotation of M. rileyi. Comparative studies of its genome among different isolates and species could provide new insights on differential pathogenicity and improved understandings of its relationships to phylogenetically related species.
