cDNA-AFLP na identificação de genes relacionados a qualidade fisiológica

Abstract: RESUMO -Alguns trabalhos têm evidenciado a existência de genótipos de soja contrastantes para qualidade fisiológica de semente. Tais diferenças existem em virtude da presença de sementes com total ou parcial impermeabilidade do tegumento à água, o que as tornam menos susceptíveis aos danos mecânicos, as adversidades climáticas e a deterioração por umidade. A característica de tegumento semi-permeável pode ser incorporada às cultivares de alta produção por meio dos programas de melhoramento. No entanto, há nece… Show more

“…The variation in the fingerprinting of cultivars suggested to be related to genetic contamination occurred between the batches studied, and exogenous contamination. Mertz et al (2009) tried to verify the effectiveness of the technique of cDNA-AFLP in obtaining fragments of genes differentially expressed in soybean seed coats with contrasting permeability and have concluded that the technique could be a promising alternative for studies aimed at identifying genes related to seed quality. According to the authors, the cDNA-AFLP technique is effective in identifying genes expressed, because it allowed the taking of 47 differentially expressed cDNA fragments between the coats of soybean genotypes CD-202 and TP.…”

“…A semente da soja apresenta variações de tonalidades na coloração do tegumento, característica esta que é controlada por vários genes (Carvalho e Nakagawa 2000, Mertz et al 2009). As sementes com tegumento preto são linhagens não melhoradas, apesar de apresentarem o tegumento semi-permeável, não são utilizadas comercialmente, pois estas características não estão presentes nas cultivares modernas (Mertz et al 2009).…”
