|Outline of Final Research Achievements
Fagaceae includes typical masting species that exhibit highly synchronized and fluctuating acorn production. There is rich phenotypic diversity in the Fagaceae, including morphology of acorns and leaves, flowering time (spring to fall), modes of pollination (wind or animal) and leaf habit (deciduous or evergreen). Because of this rich phenotypic diversity, the Fagaceae is a good target to explore the genetic basis of trait diversification. Here we investigated the diversification of reproductive strategies in the Fagaceae by comparing the resource investment strategy for floral and fruit organs, and estimating the gene regulatory network by comparative field transcriptomics. We found that the expression of genes involved in drought stress response, reactive oxygen species scavenging in early summer and genes involved in pollen tube elongation and female gametophyte maturation was significantly difference among species.
