“…Accurate identification of subgroups within the Gilo group using molecular makers could be helpful for eggplant improvement programs. For example, resistance to bacterial wilt disease caused by Ralstonia solanacearum has been reported in the S. aethiopicum Gilo group [7], but it is important to exactly know which of the three subgroups, "N'Drowa" and "Klogbo" (cultivated) and "Gnangnan" (spontaneous), actually displays resistance or the best resistance.…”

Abstract:The Solanum aethiopicum Gilo group, described as homogeneous, shows a high diversity, at least at the morphological level. In Côte d'Ivoire, farmers distinguish three subgroups, named "N'Drowa", "Klogbo" and "Gnangnan", within this group. Data were obtained from 10 quantitative and 14 qualitative morpho-agronomic traits measured in 326 accessions of Gilo eggplants, at flowering and fruiting stages. Univariate and multivariate analyses allowed clearly clustering the studied accessions into the three subgroups. Fruit taste, leaf blade width, fruit diameter, leaf blade length, fruit weight, fruit color at commercial ripeness, petiole length, germination time, plant breadth, fruit position on the plant, fruit length and flowering time were, in decreasing order, the twelve most discriminating traits. Compared to the "Gnangnan" subgroup, the "N'Drowa" subgroup has smaller plant breadth and larger leaves. The fruits of this subgroup were mainly white at commercial ripeness, larger and sweeter. Most of the traits of the "Klogbo" subgroup were intermediate between those of the "N'Drowa" and "Gnangnan" subgroups. Our results could contribute to a better understanding of S. aethiopicum diversity and to the development of a core collection for African eggplant breeding. OPEN ACCESSAgriculture 2014, 4 261

“…Despite its economic importance, compared to other major vegetable crops, few efforts have been made to use related species for the genetic enhancement of common eggplant (Solanum melongena L.). In this respect, resistance and tolerance to biotic and abiotic stresses, as well as high levels of bioactive compounds have been found in S. melongena relatives (Collonnier et al, 2001b;Plazas et al, 2014b;Rotino et al, 2014), but they have not been widely used in breeding programs.…”

"Nothing in life is to be feared, it is only to be understood. Now is the time to understand more, so that we may fear less." Maria Salomea Skłodowska-Curie AgradecimientosAunque parezcan mucho menos, ya siete son los años que llevo en el COMAV. Los años pasan volando cuando el ambiente de trabajo es estimulante, constructivo, apasionante, gratificante, motivador, intrigante, creativo, integrador, cooperativo, productivo, positivo, divertido…, familiar.Todo empezó aquella tarde del 10 de noviembre del 2010, cuando Lola Raigón, a quien va mi eterna gratitud, me presentó la persona que iba a cambiar mi vida, Jaime Prohens.Jaime, la admiración, el respeto y la gratitud que siento por ti no se pueden expresar en unas pocas frases. Eres la persona que más me ha enseñado, motivado y animado en estos años. Has conseguido sacar de mí unas cualidades que ni siquiera había imaginado tener. Tu inteligencia, sabiduría, humildad, paciencia, hacen de ti un verdadero líder. Gracias por estar pendiente en cada momento, espero colaborar contigo durante muchos años más. Eres un ejemplo a seguir y fuente de inspiración y guía para mi y muchas personas.Mi formación doctoral no sería completa si no hubiera sido por tí, Santi. Intelligente, simpatíco, caótico, siempre de buen humor y "runner".Gracias por todo el conocimiento, las buenas ideas, las clases de Génomica, las risas y los videos "frikis" que has compartido conmigo. Gracias por alegrar nuestros días.Mariola, aunque burocráticamente no has podido ser mi co-directora, te agradezco el apoyo, motivación y alegría de estos años. Aunque ahora pasamos todo el día en los despachos, echo de menos los primeros años de laboratorio, cuando pasábamos horas y horas hablando de lo que fuera. Junto a Jaime y Santi, eres un pilar de "Los Berenjen@s".Gracias a mi "hermano mayor" Javi, por los muchos momentos de amistad pasados juntos, por tu inteligencia, por compartir tus experiencias, por tu buen gusto musical, tu escepticismo, por ser un gran amigo."Los Berenjen@s" se han ido multiplicando y muchas son las entradas que hemos recolectado en estos años alrededor del mundo. Me hubiera gustado escribir algo sobre cada uno de vosotros, pero necesitaría otro capítulo de tesis, así que os agradeceré de forma conjuntas.Gracias Abou, Adriana, Agustín, Alba E., Alba L., Alessio, Andrea, Arantxa, Arunika, Bianca, Brice, Camil, Carolina, Celia, Celine, Cristina, Dani, David, Dionís, Dora, Edgar, Elena C., Elena R., Elisa, Francesco, Giulio, Gloria, Ioana, Irene, Isa, Juan, Juan Pablo, Judith, Lahiru, Lara, Laura, Loles, Maria, Marieta, Michael, Muditha, Nacho, Nadia, Nirasha, Noelia, Orsi, Pelin, Prashant, Ramses, Ranil, Rory, Silia, Sorin, Trong, por haber aportado vuestro granito de arena para la realización de esta tesis y de colaboraciones varias. Todos, los que todavía estáis por aquí y los que se han ido, habéis dejado una huella en el laboratorio y en mí (Pido disculpa si se me ha olvidado alguien, sois muchos los que se han pasado por el labo).Gracias también a todos mis compañeros del COMAV,...

Compendium of Transgenic Crop Plants

Eggplant ( Solanum melongena L.) is one of the important vegetable crops cultivated in various tropical and temperate parts of the world. There is a wide genetic diversity in the cultivated as well as wild species of eggplant. Although, the cultivated eggplant varieties are susceptible to various diseases and pests as well as abiotic stresses, the wild relatives of eggplant are good source of resistance against biotic and abiotic stresses. Therefore, attempts have been made to introgress these agronomically important traits from wild species to cultivated varieties of eggplant, but with limited success. Nevertheless, eggplant is quite amenable for plant regeneration through cell and tissue culture. Haploidisation, somatic hybridization and gene transfer methods have been well established for this crop. The beneficial traits like resistance to bacterial and fungal wilts have successfully been transferred from wild species to cultivated eggplants by protoplast fusion. However, the development of molecular markers and transgenic eggplants with novel traits is in infancy. Eggplant transgenics for insect resistance, abiotic stress tolerance, and parthenocarpy have been accomplished. More work is needed in this direction to produce eggplant transgenics for other agronomic traits, including disease resistance, nematode resistance, quality and shelf‐life of fruits. Modern biotechnological tools like RNA interference (RNAi) are useful to achieve these goals. The initiation of complete genome sequencing of eggplant is required to discover several useful genes, which can be introduced into eggplant and other crop species for genetic improvement. This chapter reviews the various aspects of eggplant biology, particularly the developments in eggplant biotechnology and future projections.
