The Plant Ontology facilitates comparisons of plant development stages across species [PDF]
, 2019 The Plant Ontology (PO) is a community resource consisting of standardized terms, definitions, and logical relations describing plant structures and development stages, augmented by a large database of annotations from genomic and phenomic studies.

Planetary Growth with Collisional Fragmentation and Gas Drag [PDF]
, 2010 As planetary embryos grow, gravitational stirring of planetesimals by embryos strongly enhances random velocities of planetesimals and makes collisions between planetesimals destructive.

Digital Three-Dimensional Atlas of Quail Development Using High-Resolution MRI [PDF]
, 2007 We present an archetypal set of three-dimensional digital atlases of the quail embryo based on microscopic magnetic resonance imaging (µMRI). The atlases are composed of three modules: (1) images of fixed ex ovo quail, ranging in age from embryonic day 5

Planetesimal disk evolution driven by embryo-planetesimal gravitational scattering [PDF]
, 2002 The process of gravitational scattering of planetesimals by a massive protoplanetary embryo is explored theoretically. We propose a method to describe the evolution of the disk surface density, eccentricity, and inclination caused by the embryo ...

Oct4 regulates DNA methyltransferase 1 transcription by direct binding of the regulatory element
Cellular & Molecular Biology Letters, 2018 Background The transcription factor Oct4 plays a pivotal role in the pre-implantation development of the mouse embryo. DNA methyltransferase 1 (Dnmt1) maintains the changes in DNA methylation during mammalian early embryonic development.

The effect of cadmium on the bovine in vitro oocyte maturation and early embryo development [PDF]
, 2019 Common pollutants such as heavy metals and cadmium is among those with high environmental concerns. In vivo studies had shown that cadmium (Cd) causes oocyte degeneration and embryo mortality, and lowers pregnancy rates in mammals.

Highly efficient RNA-guided base editing in rabbit
Nature Communications, 2018 Base editors can make targeted changes without inducing a double-stranded break. Here, the authors apply the BE3 and ABE7.10 systems to rabbit to create highly efficient targeted base substitutions and various mutation types, and show reduced frequency ...
