Gibberellin 2-oxidase 1(CsGA2ox1) involved gibberellin biosynthesis regulates sprouting time in camellia sinensis.

ABSTRACT:

Background

Tea is an important cash crop and buds are its main product. To elucidate the molecular mechanism of the sprouting time of tea plants, 'Yuchunzao', which was an early sprouting tea cultivar, was studied. 'Echa 1', sprout one week later than 'Yuchunzao' in spring, was used as the control.

Results

A total of 26 hormonal compounds and its derivatives in tea plants were qualified by using Ultra Performance Liquid Chromatography-Tandem mass spectrometry (UPLC-MS/MS). The result showed that GA₂₀, GA₃ and ICA were significantly different in 'Yuchunzao' than in 'Echa 1', with GA₂₀ and GA₃ up-regulated and ICA down-regulated. Based on the Illumina platform, transcriptome analysis revealed a total of 5,395 differentially expressed
