the identification of a second member of the RNase H2 complex, RNase H2B, being able to complement the root growth phenotype of WEE1(KO) plants, is reported.
Title: Lack of RNase H2 activity rescues HU-sensitivity of WEE1 deficient plants.

mutant alleles of the genes encoding subunits of the ribonuclease H2 (RNase H2) complex, known for its role in removing ribonucleotides from DNA-RNA duplexes, were identified as suppressor mutants of WEE1 knockout plants.
Title: Arabidopsis thaliana RNase H2 deficiency counteracts the needs for the WEE1 checkpoint kinase but triggers genome instability.

The plant WEE1 kinase acquired an indirect developmental function that is important for meristem maintenance upon replication stress.
Title: The Arabidopsis thaliana checkpoint kinase WEE1 protects against premature vascular differentiation during replication stress.

The WEE1 gene is not rate-limiting for cell cycle progression under normal growth conditions but is a critical target of the ATR-ATM signaling cascades that inhibit the cell cycle upon activation of the DNA integrity checkpoints.
Title: Arabidopsis WEE1 kinase controls cell cycle arrest in response to activation of the DNA integrity checkpoint.
