A multigene family encoding surface glycoproteins in Trypanosoma congolense

open access: yesMicrobial Cell, 2017
Trypanosoma congolense, the causative agent of the most important livestock disease in Africa, expresses specific surface proteins involved in its parasitic lifestyle. Unfortunately, the complete repertoire of such molecules is far from being deciphered.

Quadruple context-free L-System mathematical tools as origin of biological evolution [PDF]

open access: yes, 2010
It is well known that A, T, G, C annealed together early in evolution and the long stretch of DNA was found which ultimately resulted into chromosomes of different organisms.

DIFFERENTIATION OF A MULTIGENE FAMILY BETWEEN POPULATIONS [PDF]

open access: yesEvolution, 1987
Differentiation of a multigene family between populations is investigated under the forces of intrachromosomal unbiased gene conversion, neutral mutation, recombination, and random drift. The infinite-site model without recombination within the gene is employed, and the average numbers of the different sites between pairs of genes at the same locus and

Expression of genes related to flavonoid and stilbene synthesis as affected by signaling chemicals and Botrytis cinerea in grapevines

open access: yesBiologia Plantarum, 2014
Recent studies have shown that the expression of genes related to the synthesis of flavonoids, such as the phenylalanineammonia lyase (PAL), chalcone synthase (CHS), chalcone isomerase (CHI), and stilbene synthase (STS) genes were induced in response to ...

Accessing the Variability of Multicopy Genes in Complex Genomes using Unassembled Next-Generation Sequencing Reads: The Case of Trypanosoma cruzi Multigene Families

open access: yesmBio, 2022
Repetitive elements cause assembly fragmentation in complex eukaryotic genomes, limiting the study of their variability. The genome of Trypanosoma cruzi, the parasite that causes Chagas disease, has a high repetitive content, including multigene families.

Evolutionary dynamics of olfactory receptor genes in chordates: interaction between environments and genomic contents

open access: yesHuman Genomics, 2009
Olfaction is essential for the survival of animals. Versatile odour molecules in the environment are received by olfactory receptors (ORs), which form the largest multigene family in vertebrates. Identification of the entire repertories of OR genes using

Multi-gene panel testing for hereditary cancer predisposition in unsolved high-risk breast and ovarian cancer patients. [PDF]

open access: yes, 2017
PurposeMany women with an elevated risk of hereditary breast and ovarian cancer have previously tested negative for pathogenic mutations in BRCA1 and BRCA2. Among them, a subset has hereditary susceptibility to cancer and requires further testing.
