The basic helix-loop-helix leucine zipper transcription factor Mitf is conserved in Drosophila and functions in eye development.

abstract：:To investigate the genetic basis of maize adaptation to temperate climate, collections of 375 inbred lines and 275 landraces, representative of American and European diversity, were evaluated for flowering time under short- and long-day conditions.
