Molecular evolution of flower development.
Flowers, as reproductive structures of the most successful group of land plants, have been a central focus of study for both evolutionists and ecologists. Recent advances in unravelling the genetics of flower development have provided insight into the evolution of floral structures among angiosperms. The study of the evolution of genes that control floral morphogenesis permits us to draw infere...
متن کاملGenetics and evolution of inflorescence and flower development in grasses.
Inflorescences and flowers in the grass species have characteristic structures that are distinct from those in eudicots. Owing to the availability of genetic tools and their genome sequences, rice and maize have become model plants for the grasses and for the monocots in general. Recent studies have provided much insight into the genetic control of inflorescence and flower development in grasse...
متن کاملFlower development and evolution: new answers and new questions.
Certain genes have a way of rewarding continued study, as can be seen from the long histories of discoveries that have resulted from work on mammalian hemoglobin genes, on the Escherichia coli lacZ gene, and on many others. A plant gene that may fit this mold is the homeotic flower-development gene AGAMOUS (AG). In the past few years, study of the genetics and molecular genetics of this Arabido...
متن کاملThe evolution of flower development: current understanding and future challenges.
One of the most fascinating questions in evolutionary biology is understanding how novelties such as new organs or novel body plans arise. Answering this question is all the more challenging as obvious predecessors cannot always be identified in the incomplete fossil record. Evolutionary developmental (evo-devo) studies address this issue by examining how developmental mechanisms have evolved o...
متن کاملFlower development
Plants that bear flowers are called Angiosperms. With around 300,000 species, they represent the largest and most successful group in the green kingdom. Flowers contain one or more female organs, or carpels, in their center. Carpels enclose the ovules, and later the seeds. Stamens, the male pollenbearing organs, surround the carpels. Sexual organs are in turn surrounded by vegetative organs (th...
