“…Ex vitro establishment was the best in plantlets derived from 0.5 mg/l 2,4-D treatment and had no statistical difference with 1.0 mg/l 2,4-D derived plantlets. The interaction of genotype and growth regulators in regeneration either organogenesis or somatic embryogenesis is a common phenomenon (Sharma and Rajam 1995, Hansen et al 1999, Chen and Dribnenki 2002, Kantharajah and Golegaonkar 2004 and in the present work this influence was clearly manifested in different phases of regeneration.…”

Five eggplant cultivars were cultured on MS supplemented with 0.5 mg/l 2,4-D, resulting in the development of embryogenic calli. When the calli were subcultured onto growth regulator free MS, BARI Begun-4 produced the highest number of embryos (64) per explant followed by BARI Begun-1 (57). Later both the superior varieties in terms of embryo production were cultured on MS having 0.5, 1.0, 1.5 and 2.0 mg/l 2,4-D along with a control. BARI Begun-4 produced the highest number of embryos (67) on MS supplemented with 1.0 mg/l 2,4-D which was closely followed by BARI Begun-1 (62). Regenerated plantlets were successfully established in soil following acclimation.

“…For this reason, a study was made whether shoot apexes isolated from shoots sprouted from stem cuttings were a suitable source of explants for inducing SE in several cassava genotypes. Picloram (4 mg.L-1) was added to the inducing medium because high levels of auxin in SE induction medium were associated with embryo mal-formation (Kantharajah and Golegaonkar, 2004). As shown in Table 2, SE was induced in all tested genotypes, even though it was possible to detect a genotype-specific response both in terms of the frequency of SE as well as in the number of somatic embryos per explant.…”

A method for the induction of somatic embryogenesis in eight cassava genotypes from northeastern Brazil is described. The explants used were shoot apexes isolated both from in vitro grown plants and from shoots that sprouted from stem cuttings. Somatic embryogenesis was achieved in high frequencies by the addition in the induction medium of the auxin picloram over a wide range of concentrations. Green cotyledons of primary somatic embryos were used as explants to induce somatic (cyclic) secondary embryogenesis in an inducing

“…Nevertheless, conversion rates can reach up to 92% by culturing mature embryos MS solidified with 1% phytagel (Saito & Nishimura 1994;Magioli et al 2001a). A review on somatic embryogenesis in eggplant focusing on the factors that affect the process as well as its practical applications was recently published by Kantharajah & Golegaonkar (2004).…”

RESUMO -(Berinjela (Solanum melongena L.): cultura de tecidos, transformação genética e uso como planta modelo). A berinjela é uma espécie solanácea não tuberosa de importância agronômica, cultivada principalmente por seus frutos. Na medicina popular, a berinjela é indicada para o tratamento de várias doenças, incluindo diabetes, artrite, asma e bronquite. A berinjela é suscetível a várias doenças e pragas que causam perdas econômicas significativas. Esse problema tem sido abordado com técnicas convencionais de melhoramento, utilizando espécies silvestres resistentes de Solanum, que possuem uma grande diversidade genética e são fontes de genes de interesse agronômico. A aplicação de metodologias in vitro à berinjela tem resultado em sucesso considerável. Os tecidos de berinjela apresentam um alto potencial morfogenético, sendo úteis para estudos de desenvolvimento e para o estabelecimento de abordagens biotecnológicas para a produção de variedades melhoradas, tais como o resgate de embriões, a seleção in vitro, a hibridização somática e a transformação genética. O conjunto dessas características também torna a berinjela um modelo completo para estudos em diferentes áreas de pesquisa, incluindo o controle da expressão gênica e a avaliação da estabilidade de somaclones derivados de diferentes processos morfogenéticos. Neste trabalho, são analisados fatores importantes que afetam a eficiência dos processos de regeneração in vitro por meio de organogênese e embriogênese, assim como de transformação genética, explorando ainda o potencial da espécie como planta modelo para o estudo de vários aspectos da genética e fisiologia vegetais. Palavras-chave: Solanum melongena L., biotecnologia, cultura de tecidos, transformação genética, planta modelo ABSTRACT -(Eggplant (Solanum melongena L.): tissue culture, genetic transformation and use as an alternative model plant).Eggplant is an agronomically important non-tuberous solanaceous crop grown primarily for its large oval fruit. In popular medicine, eggplant is indicated for the treatment of several diseases, including diabetes, arthritis, asthma and bronchitis. Eggplant is susceptible to a number of diseases and pests capable of causing serious crop losses. This problem has been addressed by hybridizing eggplant with wild resistant Solanum species, which present a wide genetic diversity and are source of useful agronomic traits. The application of in vitro methodologies to eggplant has resulted in considerable success. Eggplant tissues present a high morphogenetic potential that is useful for developmental studies as well as for establishing biotechnological approaches to produce improved varieties, such as embryo rescue, in vitro selection, somatic hybridization and genetic transformation. Taken together, these characteristics also make eggplant a complete model for studies on different areas of plant science, including control of gene expression and assessment of genetic stability of somaclones derived from different morphogenetic processes. In the present study, importan...
