The tomato Blind gene encodes a MYB transcription factor that controls the formation of lateral meristems.

The multitude of forms observed in flowering plants is largely because of their ability to establish new axes of growth during postembryonic development. This process is initiated by the formation of secondary meristems that develop into vegetative or reproductive branches. In the blind and torosa mutants of tomato, initiation of lateral meristems is blocked during shoot and inflorescence development, leading to a strong reduction in the number of lateral axes.

High frequency of plant regeneration in sunflower from cotyledons via somatic embryogenesis.

A plant regeneration methodvia somatic embryogenesis of severalHelianthus annuus L. genotypes was developed. Starting from cotyledonary explants high frequency embryo induction was obtained following several subcultures on defined media.
