Applications de la transgenèse à l'amélioration variétale du riz

Use of genetic engineering in rice improvement Since the first recovery of a transgenic rice plant in 1988, major progress has been made in manipulating traits of interest through genetic engineering of this plant of high sociological, cultural and economic importance. These traits encompass resistance to insect pests, and fungal, bacterial and viral pathogens, tolerance to abiotic constraints ...

Influence du déficit hydrique sur la réponse physiologique du cotonnier

Physiological response of cotton (Gossypium hirsutum L.) genotype R405-2000 at the youthful stage to water deficit induced by polyethylene glycol The effect of water stress induced by polyethylene glycol (PEG) has been studied on germination and seedling growth of cotton. Five different concentrations of PEG have been tested and the results showed that PEG concentrations negatively influence se...
