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.

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.

Asymmetric thymocyte death underlies the CD4:CD8 T-cell ratio in the adaptive immune system [PDF]

, 2013
It has long been recognized that the T-cell compartment has more CD4 helper than CD8 cytotoxic T cells, and this is most evident looking at T-cell development in the thymus.

Understanding the Genetic Diversity of Mycobacterium africanum Using Phylogenetics and Population Genomics Approaches

Frontiers in Genetics, 2022
A total of two lineages of Mycobacterium tuberculosis var. africanum (Maf), L5 and L6, which are members of the Mycobacterium tuberculosis complex (MTBC), are responsible for causing tuberculosis in West Africa.

Systemic mastocytosis with associated myeloproliferative disease and precursor B lymphoblastic leukaemia with t(13;13)(q12;q22) involving FLT3. [PDF]

, 2008
Systemic mastocytoses represent neoplastic proliferations of mast cells. In about 20% of cases systemic mastocytoses are accompanied by clonal haematopoietic non-mast cell-lineage disorders, most commonly myeloid neoplasms.

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
