Aphid Resistance in Pulse Crops: Sources, Mechanisms, Genetics and Breeding

open access: yesLegume Science, Volume 8, Issue 4, December 2026.
ABSTRACT Aphids are major pests of pulse crops, causing damage through phloem sap feeding and virus transmission. In this context, resistant varieties are central components of sustainable aphid management. This review synthesizes current knowledge on resistance sources, phenotyping strategies, resistance mechanisms, genetic control and breeding ...

Mechanisms of DNA demethylation in chicken embryos. Purification and properties of a 5-methylcytosine-DNA glycosylase.

open access: yes, 1995
We have previously shown that in developing chicken embryos and differentiating mouse myoblasts, the demethylation of 5-metCpGs occurs through the replacement of 5-methylcytosine by cytosine (Jost, J. P. (1993) Proc. Natl. Acad. Sci. U.S.A. 90, 4685-4688;

The role of human alkyladenine glycosylase in cellular resistance to the chloroethylnitrosoureas

open access: yes, 2008
To investigate the possible role of glycosylase action in causing tumor resistance, a full-length, histidine-tagged human alkyladenine glycosylase has been purified from the cloned human gene contained in a pTrc99A vector propagated in a tag alkA mutant ...

Research progress on the role of the NEIL family in cancer

open access: yesFrontiers in Cell and Developmental Biology
Cancer is the primary cause of death worldwide. Cancer occurrence and progression are closely associated with DNA damage repair. DNA glycosylase were the first enzymes to initiate base excision repair, and the Nei-like DNA glycosylase (NEIL) family has ...

Human cDNA expressing a functional DNA glycosylase excising 3-methyladenine and 7-methylguanine

open access: yes, 1991
A cDNA expression library from a human cell line was introduced into an E. coli strain deficient in the repair of 3-meAde bases in DNA. E. coli strains deficient in the repair of 3-meAde are unusually sensitive to DNA methylating agents.

Relation between hOGG1 rs1052133 polymorphism with the susceptibility of hepatocellular carcinoma: a meta-analysis

open access: yesTürk Biyokimya Dergisi
Human 8-hydroxy guanine DNA glycosylase (hOGG1) is a DNA repair enzyme associated with hepatocellular carcinoma (HCC). This study aimed to investigate the pooled relationship between hOGG1 rs1052133 polymorphism and HCC susceptibility.

A common SNP in the UNG gene decreases ovarian cancer risk in BRCA2 mutation carriers

open access: yesMolecular Oncology, 2019
Single nucleotide polymorphisms (SNPs) in DNA glycosylase genes involved in the base excision repair (BER) pathway can modify breast and ovarian cancer risk in BRCA1 and BRCA2 mutation carriers.

Inefficient excision of uracil from loop regions of DNA oligomers by E.coli uracil DNA glycosylase

open access: yes, 1994
Kinetic parameters for uracil DNA glycosylase (E.coli)-catalysed excision of uracil from DNA oligomers containing dUMP in different structural contexts were determined.

DNA binding and lesion recognition by the bacterial interstrand DNA crosslink glycosylase AlkX

open access: yesEMBO Reports
Interstrand DNA crosslinks (ICLs) are a highly toxic form of DNA damage. ICL repair in both eukaryotes and bacteria involves unhooking of the two strands by specialized DNA glycosylases.
