Drosophila embryogenesis scales uniformly across temperature in developmentally diverse species [PDF]
arXiv, 2013 Temperature affects both the timing and outcome of animal development, but the detailed effects of temperature on the progress of early development have been poorly characterized. To determine the impact of temperature on the order and timing of events during Drosophila melanogaster embryogenesis, we used time-lapse imaging to track the progress of ...

Biotechnology and development of rubber planting material [PDF]
, 2009 Breeding and dissemination of planting material for rubber plantations are closely linked to propagation methods. Since the progress made by switching from multiplication by seed to propagation by budding, the development of new techniques, such as ...

Advanced Science, EarlyView.The study reports that Wnt inhibitors safeguard porcine embryonic stem cells (ESCs) from acquiring the extraembryonic endoderm (XEN) lineage, and further develop an efficient strategy to derive XEN cells from ESCs. The XEN cells from ESCs exhibit similar transcriptome and chromatin accessibility features to XEN cells from embryos and contribute to ...

Embryoids, organoids and gastruloids: new approaches to understanding embryogenesis
Development, 2017 Cells have an intrinsic ability to self-assemble and self-organize into complex and functional tissues and organs. By taking advantage of this ability, embryoids, organoids and gastruloids have recently been generated in vitro, providing a unique ...

Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]
, 2017 A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.

Advanced Science, EarlyView.The genome of Megachile rotundata, an extensively managed solitary pollination bee species, has been sequenced, covering 280.68 Mb and predicting 10 701 genes. The study reveals significant expansions of the Toll gene family and their abundant expression in diapause prepupae, highlighting enhanced immune responses during diapause. This genome serves as

The 2HA line of Medicago truncatula has characteristics of an epigenetic mutant that is weakly ethylene insensitive [PDF]
, 2016 BACKGROUND The Medicago truncatula 2HA seed line is highly embryogenic while the parental line Jemalong rarely produces embryos. The 2HA line was developed from one of the rare Jemalong regenerates and this method for obtaining a highly regenerable ...

Plac1+ Tumor Cell‐Treg Interplay Supports Tumorigenesis and Progression of Head and Neck Cancer
Advanced Science, EarlyView.Meng et al. screen genes in the CTAs family and find Plac1 is specifically expressed in head and neck squamous cell carcinoma (HNSCC) cells. They reveal that Plac1 expression promotes HNSCC progression directly by activating PI3K/AKT signaling pathway.
