Propylene Effects on Ethylene Biosynthesis in Relation to Gene Expression of ACS,ACO in Persimmon Fruit

摘要

Influences of propylene treatment on fruit softening and ethylene biosynthesis of persimmonenhance ethylene biosynthesis, with higher sensitivity of immature fruit to the propylene was consistent withmRNA increase derived from transcription of ACS and ACO genes. Furthermore, ethylene synthesis increasein immature fruits was controlled and regulated mainly by DK-ACS1, DK-ACS2, DK-ACO1 and DK-ACO2,but regulated only by DK-ACS1 and DK-ACO1 in mature fruits.
