“…Plants bearing one or more rol genes undergo changes in plant architecture, including the shortening of internodes and an increase in adventitious root formation. As dwarf phenotypes and increased rooting ability are desirable characteristics in a rootstock, this method has been employed to improve rootstocks in apple M26 (Holefors et al 1998;Zhu and Welander 1999), apple M9/29 (Zhu et al 2001), Rosa hybrida (Van der Salm et al 1997) and other plant species. Reduced plant size and modified shape are also features favoured in the breeding of ornamentals (Van der Salm et al 1997;Mercuri et al 2001).…”

Hairy roots were induced from androgenic embryos of horse chestnut (Aesculus hippocastanum L.) by infection with Agrobacterium rhizogenes strain A4GUS. Single roots were selected according to their morphology in the absence of antibiotic or herbicide resistance markers. Seventy-one putative transformed hairy root lines from independent transformation events were established. Regeneration was induced in MS liquid medium supplemented with 30 microM 6-benzylaminopurine (BA), and the regenerants were multiplied on MS solid medium containing 10 microM BA. Following elongation on MS medium supplemented with 1 microM BA and 500 mg/l polyvinylpyrrolidone, the shoots were subjected to a root-inducing treatment. Stable integration of TL-DNA within the horse chestnut genome was confirmed by Southern hybridization. The copy number of transgenes was estimated to be from two to four.

“…Somatic embryogenesis that leads the formation of an embryo from somatic cells is another procedure to regenerate fruit transformants such as banana (Vishnevetsky et al, 2011); papaya (Zhu et al, 2001); grapevine (Nirala et al, 2010) and mango (Chavarri et al, 2010). Regeneration from transformed embryos can be achieved via direct germination or shoot organogenesis and the method is useful for large-scale and rapid propagation of transformants.…”

“…For other species, the use of the rol genes for plant improvement have demonstrated production of drastic effects on the plant architecture (Rugini et al, 1991;van der Salm et al, 1997van der Salm et al, , 1998Perez-Molphe-Balch and Ochoa-Alejo 1998;Mercuri et al, 2001;Zhu et al, 2001), but scarce is the knowledge on the interaction of these genes with the genome of the Lambardi et al, 1999 plant. Moreover, the development of plants with an extensive root system and/or with reduced water consumption could be an advantage in areas with scarce water availability.…”

Biochemical and molecular procedures have been developed for olive genotyping, for taxonomy between cultivated and wild olives, for phylogenetic studies of cultivars, and for identification of usable markers linked to the most important agronomic traits, such as size of the tree, flowering induction, apical dominance, productivity, self‐fertility, quantity and quality of oil and secondary products of fruit, biotic and abiotic resistance. These characters could be introgressed into cultivars by conventional breeding or through transgeny. Successful results by classical breeding are difficult to obtain due to the different flower fertility and the long juvenile period of the progenies. The low efficiency of modern genetic improvement techniques suggests that genetic transformation techniques could speed up the development of new genotypes; however, the development of efficient regeneration methods from mature tissue is the limiting factor for applying this technology, in olive. Transgenic olive plants with modified growth habit and putative induced disease resistance are under filed conditions to test their phenotype. Other attempts of genetic improvement such as clonal selection, mutation through γ‐irradiation, protoplast technology, haploid, changes in ploidy level, somaclonal variation, and somatic hybridization are discussed and reviewed.
