To obtain new insights into the underlying regulatory mechanism of bud break in longan, a comparative analysis was conducted in three flower induction stages of two longan varieties with opposite flowering phenotypes by using isobaric tags for relative and absolute quantification (iTRAQ).<h4>Results</h4>In total, 3180 unique proteins were identified in 18 samples, and 1101 differentially abundant proteins (DAPs) were identified. "SX" ("Shixia"), a common longan cultivated variety that needs an appropriate period of low temperatures to accumulate energy and nutrients for flower induction, had a strong primary inflorescence, had a strong axillary inflorescence, and contained high contents oBMC plant biologyA comparative proteomic analysis provides insight into the molecular mechanism of bud break in longan.PMC95583621630062020003320013462020B020220006KJZD-K202201301R2020FYL01Sang XLiu LShi SJue DfalseA comparative proteomic analysis provides insight into the molecular mechanism of bud break in longan.<h4>Background</h4>The timing of bud break is very important for the flowering and fruiting of longan.
