Photodecomposition of 2, 4-dichlorophenoxyacetic acid

Crosby DG, et al.

Journal of Agricultural and Food Chemistry, 14, 596-599 (1966)

Subunit compositions of the RNA-silencing enzymes Pol IV and Pol V reveal their origins as specialized forms of RNA polymerase II.

Thomas S Ream et al.

Molecular cell, 33(2), 192-203 (2008-12-27)

In addition to RNA polymerases I, II, and III, the essential RNA polymerases present in all eukaryotes, plants have two additional nuclear RNA polymerases, abbreviated as Pol IV and Pol V, that play nonredundant roles in siRNA-directed DNA methylation and

Goldfish can recover after short-term exposure to 2,4-dichlorophenoxyacetate: use of blood parameters as vital biomarkers.

Olga I Kubrak et al.
