Developmental analysis of merosity and sexual morphs in Rubiaceae: A case study in Rubia and Cruciata

2016

The Rubiaceae is characterized by considerable diversity in floral features. To shed light on the variation of floral developmental patterns in Rubiaceae, a comparative study was carried out on pentamerous flowers of Rubia tinctorum L. and tetramerous flowers of Cruciata (Cruciata laevipes Opiz.; Cruciata glabra (L.) Ehrend.), two herbaceous genera of the tribe Rubieae. We aim to study the mechanism responsible for meristic variation and to discuss the expression of andromonoecy in C. laevipes. Developmental peculiarities include the time overlap in the initiation of petal and stamen whorls in Cruciata, the lack of calyx, and a very weak sympetaly in all species examined. Our results show t…
