<i>CsWRKY17</i> enhances Al accumulation by promoting pectin deesterification in tea plant.

ABSTRACT: The tea plant (Camellia sinensis) is a typical crop that accumulates aluminum (Al). Although the physiological mechanisms by which this occurs are well understood, their molecular mechanisms remain elusive. Here, an integrative approach combining quantitative trait locus (QTL) mapping of controlled hybridized populations and comparative transcriptomic analysis using samples treated with different Al concentrations was applied to identify candidate genes associated with Al accumulation in tea plants. Consequently, 41 candidate genes were selected using genome functional annotation of the qAl09 locus in the region of 35 256 594-57 378 817 bp on chromosome 7. Finally, a key gene, CsWRKY17, was identified as encoding a nucleus-localized transcription factor involved in reg
