One of the main results is the uncovering of a robust functional module that is sufficient to recover the gene configurations characterizing flower organ primordia.
This study is the first to functionally characterize a flowering gene, namely, JcFT, in the biofuel plant Jatropha.
While many imprinted genes have been identified and intensively studied in mammals, smaller numbers have been characterized in flowering plants, mostly in Arabidopsis thaliana.
To characterize the flower, 30 primary flowers were selected 1 day before anthesis.
Considering the origins of stamens from a petal-like organ (Goethe 1790), it is possible that the filamentous stamens that are ancestral to Zingiberales and that characterize Musa flowers are the result of a restriction of laminar growth associated with the development of fertility.
A large number of genes have been characterized as flowering time regulators, which are involved in many different pathways such as photoreception, growth regulators synthesis and response, chromatin structure or response to low temperatures [ 44, 45].
It will be necessary to characterize the entire flowering time gene network in sorghum to know how selection has shaped the photoperiod pathway of flowering time and thus helped sorghum to adapt to climatic zones with different day-length conditions.
However, natural genetic variants exist with altered floral development and morphology that can be utilized as a genetic tool to identify and characterize genes involved in flowering.
Reddish colour characterizes the flowers, which precede the leaves, the leaf stalks, the fall foliage, and the winter buds.
The plants are characterized by flowers that are usually individually small but are combined into dense, often showy inflorescences (floral clusters).
