OeAOX2 gene Linked to Rooting Ability of Olive Cuttings

March 11, 2015

Formation of adventitious roots is a key in the vegetative propagation, and is under strict genetic control. Numerous studies have been done to identify genes controlling adventitious root formation, however, only a few loci have been characterized. Mehdi Hosseini-Mazinani and Luciana Baldoni of National Institute of Genetic Engineering and Biotechnology (NIGEB) in Iran and the Institute of Biosciences and Bioresources (IBBR) in Italy, respectively, aimed to identify genes involved in rooting ability.

Candidate genes involved in rooting ability were identified in olive (Olea europaea L.) through orthologs from other plant species. The mRNA levels of these genes were analyzed during root induction in high-rooting (HR) and low-rooting (LR) individuals. Among the studied genes, only OeAOX2 was highly upregulated in high-rooting cuttings. The team then fully characterized the gene.

From the full OeAOX2 gene, alleles and effective polymorphisms were also identified and analyzed. The results provide an association between rooting ability and the OeAOX2 gene in olive.
