ABSTRACT Large-scale oil palm propagation (Elaeis guineensis Jacq.) is difficult due to its unique apical meristem. In this context, micropropagation allows the multiplication of seedlings in vitro and storage germplasm elites. This study aimed induce embryogenic calluses from leaves plants low concentrations auxins observe maintenance these characteristics during cultivation. Calluses were ind...

Rapidly growing embryogenic calli of different ages derived from the scutellum of mature seed embryos of indica rice (Rasi) and mature seeds of japonica rice (Taipei 309) was biolistically transformed. Plasmid pUCGUS containing the uidA gene encoding -glucuronidase was used to optimize transformation conditions using various combinations of helium pressure, target distance and gap distance. Pla...
