WebJul 11, 2007 · CCS52A2 is part of the Arabidopsis anaphase-promoting complex (APC), and its gene is a target for the E2F/DP-like transcriptional repressor DEL1. Over-expression of CCS52A2 causes excessive endoreduplication, while knock-outs have the opposite effect. Recent work by Inzé suggests that CCS52A2-activated APC not only promotes … WebMar 25, 2013 · CCS52A2 was previously shown to regulate QC identity and stem cell maintenance in the root meristem but lack of its function also caused defects in the organization and maintenance of the shoot apical meristem, explaining the strong effects of loss of CCS52A2 function in root and shoot development (Vanstraelen et al., 2009).

WebMay 28, 2012 · Ectopic CCS52A2 and CCS52B expression prematurely induced the endocycle and hampered mitosis, resulting in giant cells that contained fewer but enlarged nuclei. This imbalance caused by inhibition of the mitotic phase and the endocycle resulted in giant cells with less cytoplasm. This rapid switch results in giant cells of reduced size ...
