Neuron hemilineages provide the functional ground plan for the Drosophila ventral nervous system

eLife, 2015
Drosophila central neurons arise from neuroblasts that generate neurons in a pair-wise fashion, with the two daughters providing the basis for distinct A and B hemilineage groups.

Knot Fertility and Lineage

, 2017
In this paper, we introduce a new type of relation between knots called the descendant relation. One knot $H$ is a descendant of another knot $K$ if $H$ can be obtained from a minimal crossing diagram of $K$ by some number of crossing changes. We explore

Organellar inheritance in the green lineage: insights from Ostreococcus tauri [PDF]

, 2013
Along the green lineage (Chlorophyta and Streptophyta), mitochondria and chloroplast are mainly uniparentally transmitted and their evolution is thus clonal. The mode of organellar inheritance in their ancestor is less certain.

Imaging cell lineage with a synthetic digital recording system [PDF]

, 2020
Cell lineage plays a pivotal role in cell fate determination. Chow et al. demonstrate the use of an integrase-based synthetic barcode system called intMEMOIR, which uses the serine integrase Bxb1 to perform irreversible nucleotide edits.

SARSMutOnto: An Ontology for SARS-CoV-2 Lineages and Mutations

Viruses, 2023
Mutations allow viruses to continuously evolve by changing their genetic code to adapt to the hosts they infect. It is an adaptive and evolutionary mechanism that helps viruses acquire characteristics favoring their survival and propagation. The COVID-19

Molecular recording of mammalian embryogenesis. [PDF]

, 2019
Ontogeny describes the emergence of complex multicellular organisms from single totipotent cells. This field is particularly challenging in mammals, owing to the indeterminate relationship between self-renewal and differentiation, variation in progenitor
