... also localized specifically in the companion cells in maize leaves [17] and in castor bean [27]. This localization in common oak leads also to suggest an involvement of SuSy in controlling sugar fluxes ... particular in phloem companion cells of the underlying internodes. Such localization is in agreement with the results of Kleines et al. [13], who showed a high...
