Mango is an important commercial crop in India that supports livelihood options for orchardists. Dashehari mango, grown in northern India is one of the best mango varieties, as it is delicious in taste and aroma and has a high pulp. Dashehari has gained popularity because of its unique taste and ûavour. In the present study expression analysis (RT-PCR) of 14 different genes was analyzed during fruit development and ripening (jelly seed) i.e. 30 dpa, 50 dpa, 75 dpa, and jelly seed in mango cv. Dashehari. Expression of ERF119 and RAP2-12 was found to be high during fruit development and jelly seed pulp suggests ERF119 and RAP2-12 play an important role during normal fruit development as well as mango ripening. Expression of ACO and ACS was found at 75 dpa and ripening. Expression of MYB5 was found during 30 dpa and 50 dpa while CNR, AUX1, PR, peroxidase, and PG were expressed throughout development and ripening. Expression of expansin was down-regulated from 30 dpa, 50 dpa, 75 dpa, and high at jelly seed (ripe). Expression patterns of the genes during fruit development and jelly seed indicated that they are involved in mango fruit development and jelly seed formation by the different transcription factor signalling pathways.
