Transformação genética da batata cultivar Achat via Agrobacterium tumefaciens

Abstract: O melhoramento genético tradicional da batata (Solanum tuberosum L.) é lento e defronta-se com uma gama de dificuldades. A espécie cultivada é tetraplóide com segregação polissômica, e muitas das cultivares comerciais apresentam baixa fertilidade de pólen ou não florescem (Vayda et al., 1992). Nesse cenário, a utilização das técnicas de transformação genética em batata teria a vantagem de possibilitar a incorporação, em clones considerados elites, de genes específicos que codificam características de interesse… Show more

“…Atlantic, wherein, from combination of zeatin, IAA (3-indol-acetic acid) and NAA, regeneration protocols were established for in vitro cultivation. Torres et al, 2000, whom studied cv. Achat, achieved success in regeneration using basic MS medium supplemented with zeatin at a 5.00 mg L -1 concentration and rooting using 0.05 mg L -1 of NAA.…”

“…New knowledge acquired after complete potato genome sequencing (TPGSC, 2011) opened a range of possibilities to genetic manipulation, specially through genetic transformation due to the high potato susceptibility to Agrobacterium tumefaciens infection (Vayda and Belknap, 1992). Recombinant DNA technology and plant regeneration from tissue culture have been successfully employed to introduce exogenous genes into an agricultural plant of interest, besides allowing better understanding regarding the role of different genes and metabolic pathways (Vayda and Belknap, 1992;Torres et al, 2000;Romano et al, 2001;Homrich et al, 2012). Regeneration of feasible plantlets is a limiting step of genetic transformation protocols and most of the tissue culture process is highly genotype dependent.…”

“…A utilização de AIA combinado com ZEA, promoveu a inibição da brotação para ambos tipos de explantes. Torres et al (2000), verificaram que na regeneração de plantas de batata cultivares Baronesa e Macaca, entrenós se mostraram mais eficentes que explantes foliares. Campos (1995) trabalhando com batata cv.…”
