Decoupled maternal and zygotic genetic effects shape the evolution of development

open access: yeseLife, 2018
Evolutionary transitions from indirect to direct development involve changes in both maternal and zygotic genetic factors, with distinctive population-genetic implications, but empirical data on the genetics of such transitions are lacking.

Genetic interactions that promote the floral transition inArabidopsis [PDF]

open access: yesSeminars in Cell & Developmental Biology, 1996
The transition from vegetative to reproductive development is marked by the establishment of the floral developmental program in the lateral primordia formed by the shoot apical meristem. This is achieved by the coordinate activation, in these primordia, of a set of genes that regulate floral initiation.

Singular limit of an activator-inhibitor type model

open access: yesNetworks and Heterogeneous Media, 2012
We consider a reaction-diffusion system of activator-inhibitor type arising in the theory of phase transition. Itappears in biological contexts such as pattern formation in population genetics.

The occipital lateral plate mesoderm is a novel source for vertebrate neck musculature [PDF]

open access: yes, 2010
In vertebrates, body musculature originates from somites, whereas head muscles originate from the cranial mesoderm. Neck muscles are located in the transition between these regions.

Understanding the biology of urothelial cancer metastasis

open access: yesAsian Journal of Urology, 2016
Management of unresectable urothelial cancer (UC) has been a clinical challenge for decades. While drug resistance is a key issue, precise understanding of biology of UC metastasis is another challenge for the improvement of treatment outcome of UC ...

Genetic conditions of short stature: A review of three classic examples

open access: yesFrontiers in Endocrinology, 2022
Noonan, Turner, and Prader-Willi syndromes are classical genetic disorders that are marked by short stature. Each disorder has been recognized for several decades and is backed by extensive published literature describing its features, genetic origins ...

Simulation from endpoint-conditioned, continuous-time Markov chains on a finite state space, with applications to molecular evolution [PDF]

open access: yes, 2009
Analyses of serially-sampled data often begin with the assumption that the observations represent discrete samples from a latent continuous-time stochastic process.
