Transcriptome Analysis from leaf during non-flowering vegetative growth phase of mango (Mangifera indica L. var Fazli) from Murshidabad district of West Bengal, India.

Abstract

Mango (Mangifera indica L.) is a major fruit crop in numerous tropical and subtropical countries, facing various problems such as susceptibility to diseases, bi-annual production, low yield and a brief shelf life of the fruit, in cultivation. Traditional breeding methods have limited success in improving the quality of this fruit crop due to prolonged time of maturity, self-incompatibility and high degree of heterozygosity in breeding lines. However, recent studies utilizing genomic analysis have identified key genes responsible for economically important characters, suggesting the possibility of Marker Assisted Selection (MAS) in breeding lines through transgenic or specific genotype selection from seedlings. With the rapid advancements in genome sequencing and bioinformatics, it is now feasible to identify, label, clone, and manipulate numerous genes related to economically important characters. While research on the flowering and fruiting of mango has been extensive, research studies to preliminarily identify the functions of mango genes during the vegetative growth phase is very few. The major findings include few highly active genes viz. WRKY, NAM, MYB, GoGID1 which is channelizing the energy towards vegetative growth and inhibit flowering genes.
