DIPLOID DOMINANCE. "The dominance of the diploid state in higher organisms, with haploidy generally confined to the gametic phase, has led to the perception that diploidy is favored by selection. This view is highlighted by the fact that no known female organism within the Metazoa exists exclusively (or even for a prolonged period) in a haploid state." https://lnkd.in/gYgazXK View in LinkedIn

ROOT GROWTH SPECIFICITY. "Considerable specificity appears to be conveyed by roots: the growth patterns of roots have shown to depend on neighbour genotype, neighbour species, whether neighbouring roots are self- or non-self or connected by stolons, even in genetically identical individuals." http://rsbl.royalsocietypublishing.org/content/3/4/435.short View in LinkedIn

SO ENDS this perspective on the nuanced and complicated lives of plants. It has been often stated that because they move slowly, human are often sublimely oblivious to these phenomena. But with the help of time lapse cinematography, we can appreciate a little more their animated live, growth and mating cycles. https://lnkd.in/gvP8Mxa View in LinkedIn

PARTHENOGENIC MAMMALIAN EMBRYOS. "Parthenogenetic haploid embryonic stem cells efficiently support mouse generation by oocyte injection. Mammalian haploid embryonic stem cells (haESCs) have been recently generated from parthenogenetic and androgenetic embryos. Both parthenogenetic haESCs (PG-haESCs) and androgenetic haESCs (AG-haESCs) can be used for cell-based reverse and forward genetic screens on a whole-genome scale." https://lnkd.in/gdkjfHz View in LinkedIn

HAPLOID HUMAN STEM CELLS. "Here we generated and analysed a collection of human parthenogenetic ES cell lines originating from haploid oocytes, leading to the successful isolation and maintenance of human ES cell lines with a normal haploid karyotype. Haploid human ES cells exhibited typical pluripotent stem cell characteristics, such as self-renewal capacity and a pluripotency-specific molecular signature." (ES = embryonic stem cells). https://lnkd.in/gQeEBUz View in LinkedIn
