PusALDH1 gene confers high levels of volatile aroma accumulation in both pear and tomato fruits.Aroma is an important commercial trait that determines fruit quality and has an important influence on the overall flavor of fruits.  In this study, via genome resequencing we identified one gene PusALDH1 (Pbr034873.1) related to aroma biosynthesis that can respond to the induction of methyl jasmonate.  Transient transformation of pear fruits and heterologous stable transformation of tomato further confirmed the function of PusALDH1 in aroma accumulation.  Meanwhile, transgenic tomato fruits with PusALDH1 overexpression exhibited a greater area of yellow placenta, indicating that the gene may be related to the growth and development of the fruit.  Taken together, PusALDH1 could act as a strong candidate gene in aroma synthesis.
