In this study, we investigate the chloroplast-related changes occurring during pea cold acclimation, in order to further lead to genetic improvement of its field performance. Champagne and Térèse, two pea lines with different acclimation capabilities, were studied by physiological measurements, sub-cellular fractionation followed by relative protein quantification and two-dimensional DIGE. The chilling tolerance might be related to an increase in protein related to soluble sugar synthesis, antioxidant potential, regulation of mRNA transcription and translation through the chloroplast. Freezing tolerance, only observed in Champagne, seems to rely on a higher inherent photosynthetic potential at the beginning of the cold exposure, combined with an early ability to start metabolic processes aimed at maintaining the photosynthetic capacity, optimizing the stoichiometry of the photosystems and inducing dynamic changes in carbohydrate and protein synthesis and/or turnover.Lire moins >
