Evolution of asexual reproduction in leaves of the genus Kalanchoë.
Plant somatic cells have the remarkable ability to regenerate an entire organism. Many species in the genus Kalanchoë, known as "mother of thousands," develop plantlets on the leaf margins. Using key regulators of organogenesis (STM) and embryogenesis (LEC1 and FUS3) processes, we analyzed asexual reproduction in Kalanchoë leaves. Suppression of STM abolished the ability to make plantlets. Here...
متن کاملAsexual Reproduction in Holothurians
Aspects of asexual reproduction in holothurians are discussed. Holothurians are significant as fishery and aquaculture items and have high commercial value. The last review on holothurian asexual reproduction was published 18 years ago and included only 8 species. An analysis of the available literature shows that asexual reproduction has now been confirmed in 16 holothurian species. Five addit...
متن کاملTHE EVOLUTION OF ASEXUAL FUNGI: Reproduction, Speciation and Classification.
Phylogenetic and population genetic methods that compare nucleic acid variation are being used to identify species and populations of pathogenic fungi and determine how they reproduce in nature. These studies show that asexual or sexual reproductive morphology does not necessarily correlate with clonal or recombining reproductive behavior, and that fungi with all types of reproductive morpholog...
متن کامل Structure Learning in Bayesian Networks Using Asexual Reproduction Optimization
A new structure learning approach for Bayesian networks (BNs) based on asexual reproduction optimization (ARO) is proposed in this letter. ARO can be essentially considered as an evolutionary based algorithm that mathematically models the budding mechanism of asexual reproduction. In ARO, a parent produces a bud through a reproduction operator; thereafter the parent and its bud compete to survi...
متن کاملAsexual Reproduction in Acoelous Turbellaria †
Among the turbellarian flatworms reproduction is typically associated with a sexual process. However, in certain orders such as the Tricladida and Rhabdocoela asexual reproduction is also recognized.8 The purpose of this short paper is to report the discovery of asexual reproduction by what is probably a fission-like process in another order of Turbellaria, the Acoela. Asexual reproduction was ...
