Natural Allelic Variations in IbCHYR1–IbZnFR Complex Regulate Fusarium Root Rot Resistance in Sweet Potato

Advanced Science, EarlyView.
FfRlpA2, a conserved Fusarium effector, functions as a protease inhibitor by hijacking the E3 ubiquitin ligase IbCHYR1 to degrade the resistance factor IbZnFR, thereby promoting Fusarium pathogenicity. Conversely, the high dosage Pro::IbZnFRHap2 allele was associated with resistance to root rot disease.

Virus Replication as a Phenotypic Version of Polynucleotide Evolution

, 2013
In this paper we revisit and adapt to viral evolution an approach based on the theory of branching process advanced by Demetrius, Schuster and Sigmund ("Polynucleotide evolution and branching processes", Bull. Math. Biol.

BLM–DNA2–RPA–MRN and EXO1–BLM–RPA–MRN constitute two DNA end resection machineries for human DNA break repair [PDF]

, 2011
Repair of dsDNA breaks requires processing to produce 3′-terminated ssDNA. We biochemically reconstituted DNA end resection using purified human proteins: Bloom helicase (BLM); DNA2 helicase/nuclease; Exonuclease 1 (EXO1); the complex comprising MRE11 ...

A Two‐Component Pseudo‐Icosahedral Protein Nanocompartment with Variable Shell Composition and Irregular Tiling

Advanced Science, EarlyView.
The structure and assembly principles of a two‐component encapsulin nanocompartment shell are reported. The two‐component protein compartment self‐assembles from two distinct HK97‐fold shell proteins into a pseudo‐icosahedral protein shell with variable composition and irregular tiling.

Pseudomonas aeruginosa Polynucleotide Phosphorylase Contributes to Ciprofloxacin Resistance by Regulating PrtR

Frontiers in Microbiology, 2019
Pseudomonas aeruginosa is an opportunistic bacterial pathogen that causes various acute and chronic infections. It is intrinsically resistant to a variety of antibiotics. However, production of pyocins during SOS response sensitizes P.

Linker region is required for efficient nuclear localization of polynucleotide kinase phosphatase.

PLoS ONE, 2020
Polynucleotide kinase phosphatase (PNKP) is a DNA repair factor with dual enzymatic functions, i.e., phosphorylation of 5'-end and dephosphorylation of 3'-end, which are prerequisites for DNA ligation and, thus, is involved in multiple DNA repair ...

Rapid nanopore discrimination between single polynucleotide molecules.

Proceedings of the National Academy of Sciences of the United States of America, 2000
A variety of different DNA polymers were electrophoretically driven through the nanopore of an alpha-hemolysin channel in a lipid bilayer. Single-channel recording of the translocation duration and current flow during traversal of individual ...
