The availability of a large number of expressed sequence tags (ESTs) has facilitated the development of molecular markers in members of the grass family. As these markers are derived from coding sequences, cross-species amplification and transferability is higher than for markers designed from genomic DNA sequences. In this study, 919 EST-based primers developed from seven grass species were assessed for their amplification across a diverse panel of 16 grass species including cereal, turf and forage crops. Out of the 919 primers tested, 89 successfully amplified DNA from one or more species and 340 primers generated PCR amplicons from at least half of the species in the panel. Only 5.2% of the primers tested produced clear amplicons in all 16 species. The majority of the primers (66.9%) were developed from tall fescue and rice and these two species showed amplification rate of 41.6% and 19.0% across the panel, respectively. The highest amplification rate was found for conserved-intron scanning primers (CISP) developed from pearl millet (91%) and sorghum (75%) EST sequences that aligned to rice sequences. The primers with successful amplification identified in this study showed promise in other grass species as demonstrated in differentiating a set of 13 clones of reed canary grass, a species for which very little genomic research has been done. Sequences from the amplified PCR fragments indicated the potential for the transferable CISP markers for comparative mapping purposes. These primer sets can be immediately used for within and across species mapping and will be especially useful for minor grass species with few or no available molecular markers.

Progenies F6 de soja, oriundas de selecoes entre familias F5 do cruzamento 'FT-Cometa' x 'IAC-8', foram avaliadas em Vicosa,MG. Os coeficientes de correlacoes entre nove caracteres quantitativos foram desdobrados em efeitos diretos e indiretos, considerando-se um diagrama em cadeia e os modelos aditivos e multiplicativos da producao de graos, alem de seus componentes primarios. As analises de trilha, com dados logaritmizados (aditivo) e nao-logaritmizado (multiplicativo), apresentaram os mesmos caracteres em ordem de importancia. Entretanto, o modelo aditivo foi mais eficiente ao traduzir a determinacao total dos componentes primarios sobre a producao de graos, devendo ser indicado para essas situacoes. O numero de vagens por planta, como componente primario, e dias para maturacao, altura da planta na maturacao e numero de nos na floracao, como componentes secundarios, aprarecem como os mais importantes no processo de selecao indireta pra aumento da producao de graos de soja. |
