Expression profiling of various genes during the fruit development and ripening of mango

2D-DIGE analysis of mango (Mangifera indica L.) fruit reveals major proteomic changes associated with ripening

“…Spot #5202 showed a 6.15-fold increase during ripening in accordance with the reported over-expression of the chitinase gene in the 'Alphonso' mango [33]. In addition to the putative anti-pathogenic role of chitinases, their hydrolytic action on cell wall glycoproteins containing N-acetylglucosamine could contribute to the softening of mango pulp [33,34]. To obtain a better understanding of this step, future work will focus on cell wall glycoprotein content and the involvement of chitinases in the ripening process.…”

“…Although mango chitinase and TLP may be involved in the defense against pathogens, they may act in other processes related to fruit quality, such as pulp softening and postharvest stress resistance. Spot #5202 showed a 6.15-fold increase during ripening in accordance with the reported over-expression of the chitinase gene in the 'Alphonso' mango [33]. In addition to the putative anti-pathogenic role of chitinases, their hydrolytic action on cell wall glycoproteins containing N-acetylglucosamine could contribute to the softening of mango pulp [33,34].…”

Geographic variation in the flavour volatiles of Alphonso mango

“…In our previous study, we have studied expression profiles of various flavour genes through the developmental and ripening stages of Alphonso from Deogad which indicated a ripening-related pattern of expression of many genes (Pandit et al, 2010). It would be interesting to study expression of these flavour genes along with the other ripening-related genes across the geographic locations to shed light on the downstream players in flavour regulation.…”

Expression and enzymatic activity of phenylalanine ammonia-lyase and p-coumarate 3-hydroxylase in mango (Mangifera indica ‘Ataulfo’) during ripening

“…The positive correlation between the expression of phenylpropanoid genes and their corresponding enzyme activity has been reported in fruits such as berries (Jaakola et al, 2002), strawberries (Almeida et al, 2007), banana (Chen et al, 2008), and others (Sanchez-Ballesta et al, 2000;Yingsanga et al, 2008;Pandit et al, 2010). These results suggested that C3H expression is regulated at the transcriptional level.…”
