“…Explants incubation in absence of light favored the regeneration of a higher number of GUS + plants (Table 3). Regarding the co-cultivation time it was observed that simple inoculation of the explants with Agrobacterium and its transfer to selection medium did not allow the regeneration of transgenic plants as also demonstrated by Cervera et al (1998) ( Table 4). The co-culture for three days increased the percentage of explants with buds, as it was possible to obtain a higher number of plants than with one day co-cultivation and a higher percentage of GUS + plants than with five days co-cultivation.…”

“…These explants can be epicotyl segments excised from seedlings germinated in darkness (Bond & Roose, 1998) and later transferred to culture conditions involving a 16 hours photoperiod, varying from one to three weeks (Cervera et al, 1998) up to three months (Pérez-Molphe-Balch & Ochoa-Alejo, 1998) or even excised from seedlings germinated under light conditions (Moore et al, 1992) or internodal segments excised from seedlings cultivated in greenhouse (Peña et al, 1995a(Peña et al, , 1997. In this work it was chosen to start using explants excised from seedlings germinated in vitro because of the efficiency in regenerating shoots (Moura et al, 2001) and the good control of contamination.…”

“…A primeira laranja transgênica regenerada foi obtida a partir de células embriogênicas em suspensão da variedade 'Washington Navel' co-cultivadas com Agrobacterium tumefaciens (HIDAKA et al, 1990). Vários métodos de transformação genética já foram descritos para citros, como a introdução direta de DNA em protoplastos (KOBAYASHI; UCHIMIYA, 1989;VARDI;BLEICHMAN;AVIV, 1990;GUO et al, 2005), transformação via A. tumefaciens (MOORE et al, 1992;FLEMING et al, 2000;BOND;ROOSE, 1998;CERVERA et al, 1998;MOORE, 1999;MENDES et al, 2002;ALMEIDA et al, 2003), o bombardeamento de partículas em células vivas (KLEIN et al, 1987;YAO et al, 1996) e por eletroporação de protoplastos (HIDAKA; OMURA, 1993;NIEDZ et al, 2003).…”

“…Diversos fatores podem afetar a eficiência de transformação, como o cultivo (CERVERA et al, 1998;PEÑA et al, 1997), a estirpe de Agrobacterium (HOLFORD; HERNANDEZ; NEWBURY, 1992; GUTIÉRREZ-E; LUTH; MOORE, 1997), o tipo de explante (MOORE et al, 1992;FLEMING et al, 2000;MENDES et al, 2002), o genótipo utilizado , e as condições de incubação no co-cultivo (BARBOSA, 2002;MENDES et al, 2002).…”

“…Os citros apresentam algumas características relacionadas à sua biologia reprodutiva, tais como, alta heterozigose, poliembrionia nucelar (apomixia), longo Agrobacterium tumefaciens, sendo esse o método mais empregado para a obtenção de plantas transgênicas de citros (HIDAKA et al, 1990;KANEYOSHI et al, 1994;PEÑA et al, 1995;GUTIÉRREZ;LUTH;MOORE, 1997;CERVERA et al, 1998aCERVERA et al, , 1998bGHORBEL et al, 2000GHORBEL et al, , 2001ALMEIDA et al, 2003;MOLINARI et al, 2004;PEÑA et al, 2004b;RODRÍGUEZ et al, 2008).…”
