Indirect organogenesis from leaf explants of Eucalyptus benthamii x Eucalyptus dunnii and shoot multiplication
Background In Brazil, especially in the Southern region, stresses caused by cold and eventual frost are those that exert the most negative effect on the productivity of Eucalyptus spp. The genetic transformation techniques may contribute to forestry improvement programs in order to obtain genotypes expressing new interesting characteristics. They allow shortening the long breeding cycles and av...
متن کاملIn vitro shoot organogenesis from Eucalyptus sp. leaf explants
Background In vitro organogenesis is one of the key techniques associated with genetic transformation, as it determines the successful regeneration of transgenic plants after co-cultivation with bacteria. Therefore, the development of efficient regeneration protocols is the most critical step in developing genetic transformation. Protocols have been developed for several species of eucalyptus. ...
متن کاملReview Crim1–, a regulator of developmental organogenesis
availability and activity is critical during embryogenesis to ensure appropriate organogenesis. This process is regulated through the coordinated expression of growth factors and their cognate receptors, as well as via proteins that can bind, sequester or localize growth factors to distinct locations. One such protein is the transmembrane protein Crim1. This protein has been shown to be express...

متن کاملDifferential Reponses to Indirect Organogenesis in Rice Cultivars
An investigation was made on the initiation, maintenance and regeneration of callus from mature seeds as explants of eight rice cultivars, viz., Khitish, IR 64, IR 36, IR 72, PNR 546, Swarna, Taraori Basmati and Gobindabhog. Mature seeds were used as explants. MS medium supplemented with 2mgL-1 of 2, 4-D was found suitable for inducing high amount of embryogeniccalli in the studied genotypes. I...
