“…5,6) Several trials to regulate enzymatic browning by repressing the expression of PPO have been conducted. [7][8][9][10] On the other hand, clariˆcation of the reactivity of polyphenol quinones is also important to understand the mechanism for enzymatic browning and to regulate the eŠect. Among the polyphenols, 5-caŠeoylquinic acid (chlorogenic acid, CQA) is one of the major polyphenol in such plants as apples, coŠee and lettuce.…”

Resistance to bruising is an important quality trait of potato depending on multiple genetic and environmental factors. Thirty one interspecific diploid hybrids and two tetraploid standards were evaluated for resistance to bruising in 2 years. Diploids originated from crosses between wild and primitive Solanum species and dihaploids of S. tuberosum. Two-year mean values of bruising resistance of tested genotypes indicated significant variability of the trait. Analysis of variance showed significant effects of genotype, year and interaction between them on the trait. Broad-sense heritability of bruising resistance was estimated as moderately high, Hb=0.73. Content of L-tyrosine, the main substrate of discoloration reaction, was not significantly correlated with brusing in tested diploid hybrids. The clones, that were resistant to blackspot bruise, also combined quality traits and resistances to many pathogens. All these traits could be transferred together into tetraploid level in 4x×2x crosses via male 2n gametes produced by diploid hybrids.Resumen La Resistencia al daño mecánico es un carácter importante en la calidad de la papa que depende de múlti-ples factores genéticos y del ambiente. Se evaluaron 31 híbridos diploides interespecíficos y dos estándares tetraploides para resistencia a la magulladura en dos años. Los diploides se originaron de las cruzas entre especies silvestres y primitivas de Solanum y dihaploides de S. tuberosum. Los valores de las medias de dos años de resistencia al daño de los genotipos probados indicaron variabilidad significativa del carácter. El análisis de varianza mostró efectos significativos de genotipo, año e interacción entre ellos en el carácter. Heredabilidad, en un amplio sentido de resistencia al daño mecánico, se estimó como moderadamente alta, Hb=0.73. El contenido de L-tirosina, el principal sustrato de la reacción de oscurecimiento no estuvo correlacionado significativamente con el daño en los híbridos diploides probados. Los clones, que fueron resistentes a la mancha oscura, también combinaron los caracteres de calidad y resistencia a muchos patógenos. Todos estos caracteres pudieron transferirse juntos a nivel tetraploide en cruzas 4x × 2x vía gametos macho 2n producidos en híbridos diploides.

“…Silencing of PPO genes in potato leads to a reduction in enzymatic browning of tuber tissue due to wounding and bruising from impact (Bachem et al 1994;Coetzer et al 2001;Chi et al 2014). Innate TM potato will contain black spot bruise resistance through down-regulation of PPO (Fig.…”

Potato is the world's most important vegetable crop, with nearly 400 million tons produced worldwide every year, lending to stability in food supply and socioeconomic impact. In general, potato is an intensively managed crop, requiring irrigation, fertilization, and frequent pesticide applications in order to obtain the highest yields possible. Important traits are easy to find in wild relatives of potato, but their introduction using traditional breeding can take 15-20 years. This is due to sexual incompatibility between some wild and cultivated species, a desire to remove undesirable wild species traits from adapted germplasm, and difficulty in identifying broadly applicable molecular markers. Fortunately, potato is amenable to propagation via tissue culture and it is relatively easy to introduce new traits using currently available biotech transformation techniques. For these reasons, potato is arguably the crop that can benefit most by modern biotechnology. The benefits of biotech potato, such as limited gene flow to conventionally grown crops and weedy relatives, the opportunity for significant productivity and nutritional quality gains, and reductions in production cost and environmental impact, have the potential to influence the marketability of newly developed varieties. In this review we will discuss current and past efforts to develop biotech potato varieties, traits that could be impacted, and the potential effects that biotech potato could have on the industry.Resumen La papa es el cultivo hortícola más importante en el mundo, con cerca de 400 millones de toneladas producidas a nivel mundial anualmente, acreditando la estabilidad en el suministro de alimentos e impacto socioeconómico. En general, la papa es un cultivo manejado intensivamente, que requiere riego, fertilización y aplicaciones frecuentes de plaguicidas para obtener los más altos rendimientos posibles. Los caracteres importantes son fáciles de encontrar en parientes silvestres de la papa, pero su introducción usando el mejoramiento tradicional puede llevar de 15 a 20 años. Esto es debido a la incompatibilidad sexual entre algunas especies silvestres y cultivadas, el deseo para eliminar características indeseables de las especies silvestres del germoplasma adaptado, y la dificultad en la identificación de marcadores moleculares aplicables ampliamente. Afortunadamente, la papa es receptiva a la propagación por cultivo de tejidos y es relativamente fácil la introducción de nuevos caracteres usando técnicas biotecnológicas de transformación actualmente disponibles. Por estas razones, la papa es probablemente el cultivo que se puede beneficiar mayormente por la biotecnología moderna. Los beneficios de la papa biotecnológica, como el flujo genético limitado a cultivos que se siembran convencionalmente y a los parientes como malezas, la oportunidad para productividad significativa y logros en calidad nutricional, y las reducciones en los costos de producción e impacto ambiental, tienen el potencial para influenciar la comercialización...
