Abstract Following implantation, the human embryo undergoes major morphogenetic transformations that establish future body plan. While molecular events underpinning this process are established in mice, they remain unknown humans. Here we characterise key of morphogenesis, period between implantation and gastrulation, using single-cell analyses functional studies. First, embryonic epiblast cell...

Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...

Background: Origin of midlife copy number variations (CNVs) between tissues in non-genetic diseases is unknown. Such genomic differences caused by post-zygotic events. They might either happen during the life or due to prevalent mosaicism in preimplantation stage. We aim to explore fetal mosaicism and its origins. Materials and Methods: Two apparently normal fetuses were achieved following the ...

Hatchery production is critical to the successful aquaculture of a species. This study describes first captive breeding and reports on embryonic development early larval stages sea cucumber Holothuria sanctori, species native Mediterranean eastern Atlantic. Various induction methods were applied obtain spawning in adult H. sanctori specimens; gametes obtained from spontaneous event broodstock i...
