| Sumario: | The Citrus genus comprises a number of sensitive tropical and subtropical species to cold stress, which
limits global citrus distribution to certain latitudes and causes major economic loss. We used RNA‐Seq
technology to analyze changes in the transcriptome of Valencia delta seedless orange in response to
long‐term cold stress grafted on two frequently used citrus rootstocks: Carrizo citrange (CAR),
considered one of the most cold‐tolerant accessions; C. macrophylla (MAC), a very sensitive one. In
addition, we perform the quantification of the ABA and JAs hormones and the determination of
secondary metabolites by HPLC.
