Description
Studies on model plants have shown that temporary soil flooding exposes roots to a significant hypoxic stress resulting in metabolic re-programming, accumulation of toxic metabolites and hormonal imbalance. To date, physiological and transcriptional responses to flooding in grapevine are poorly characterized. To fill this gap, we aimed to gain insights into the transcriptional changes induced by flooding on grapevine roots (K5BB rootstocks), on which cv Sauvignon blanc (Vitis vinifera L.) plants were grafted. Over two consecutive vegetative seasons, flooding was imposed to potted vines during the late dormancy period, to mimick the most frequent waterlogging events occurring in the field. Untargeted transcriptomic approach was applied to investigate early responses of grapevine roots during exposure to hypoxia and subsequent recovery after stress removal. Overall integration of these data may be enabled us to draft a first comprehensive view of the transcriptional rearrangements involved in grapevine’s root responses and in the coordination of scion-rootstock signaling during and after exposure to waterlogging.
