"PLOIDY refers to the number of sets of chromosomes in a cell. Diploid, meaning two chromosome sets, is the most common ploidy in animals. Diploid animals generally produce haploid gametes: for example, a mouse (M. musculus) has two genome sets (2n = 40) in somatic cells, and generates haploid (n = 20) sperm and oocytes. However, these haploid cells are generally limited in their life cycle." https://lnkd.in/gHK6Jfp View in LinkedIn

HAPOID CELL LINES. "In vertebrates, the first haploid cell lines were obtained more than 40 years ago from frogs. Despite this, the availability of isolated vertebrate haploid cell lines is limited. Mammalian (especially human) haploid cell lines are of particular interest, because genetic screening in mammalian cells is directly applicable to medicinal and pharmacological research." https://lnkd.in/gHK6Jfp View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend on the theme of plant kin recognition. Here we look at the root and leaf responses of plants to the presence of kin, and at ways plants can game the relationship game to their own advantage. All these studies reinforce the fact that plants are not just plastic cut-outs, but sophisticated sentient beings. View in LinkedIn

ROOT FAMILY CHATTER. "Kin recognition by the roots of Cycas edentata was recently demonstrated. Our extensive literature search revealed this to be the first report of kin recognition in any spermatophyte other than angiosperms. Based on this new validation that the phenomenon occurs among phylogenetically diverse taxa, we conclude that kin recognition by roots may be an ancient phenomenon." https://lnkd.in/gYpA3RF 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

ROOTING CHANGES. "The annual plant, Abutilon theophrasti, shows a differential response towards the presence of a competitor and heterogeneous resource distributions. Plants sensing neighbours and grown in uniform soil nutrient distributions exhibited reductions in rooting." https://lnkd.in/d_tsqB7 View in LinkedIn
