  abstract = {{B}ackground and {A}ims {T}he pacaya palm is a dioecious neotropical palm species that is exploited in {L}atin {A}merica for its male inflorescence, which is edible when immature. {I}t is cultivated, in a non-intensive manner, in {G}uatemala, where a morphotype occurs that produces much larger, more highly branched inflorescences compared with wild palms. {W}e sought to identify molecular factors underlying this phenotypic divergence, which is likely to be a product of domestication. {M}ethods {W}e performed {RNA}-seq-based studies on immature pacaya palm male inflorescences in order to identify genes that might be directly or indirectly affected in their expression in relation to domestication. {W}e also measured the accumulation of a range of soluble sugar molecules to provide information on the biochemical status of the two different types of material. {K}ey {R}esults {A} total of 408 genes were found to display significantly different expression levels between the wild and cultivated morphotypes. {T}hree different functional categories were found to be enriched in the gene set that was upregulated in the cultivated morphotype: redox balance; secondary metabolism; and transport. {S}everal sugars were found to accumulate at higher levels in inflorescences of the cultivated morphotype, in particular myo-inositol, fructose and glucose. {C}onclusions {T}he observed upregulation of redox-related genes in the cultivated morphotype is corroborated by the observation of higher myo-inositol accumulation, which has been shown to be associated with enhanced scavenging of reactive oxygen species in other plants and which may affect meristem activity.},
