Understanding the genetic basis of ecologically important traits is a major focus of evolutionary research. Recent advances in molecular genetic techniques should significantly increase our understanding of how regulatory genes function. By contrast, our understanding of the broader macro-evolutionary implications of developmental gene function lags behind. Here we review published data on the ...

The timing and lowering type of walnut genotypes (Juglans regia L.) is one of the important factors that lead to high and constant production. Therefore, the selection of homogame and spring frost tolerant genotypes has been among the most important priorities in breeding programs of walnut. The present paper analyzed the degree of dichogamy and the flowering time of 19 promising genotypes in w...

Reproductive systems are fundamental attributes for understanding life cycle and regeneration processes provide information about seed production genetic diversity. Analyses of reproductive strategies within communities their associations with functional groups can indicate how physical biological characteristics may influence the ecology such communities. The main goal was to determine if asso...
