C2H2-type zinc finger protein PagSUPa targets PHRAGMOPLAST ORIENTING KINESIN to negatively regulate cell division during leaf development in Populus alba × P. glandulosa
Transcriptome analysis was performed on the sixth leaves of Populus alba × P. glandulosa. The twelve samples were: four PagSUPa overexpression (OE) line 2 samples 2-1-L6, 2-2-L6, 2-3-L6 and 2-4-L6, four PagSUPa OE line 7 samples 7-1-L6, 7-2-L6, 7-3-L6 and 7-4-L6, four nontransgenic control (CK)  samples CK-1-L6, CK-2-L6, CK-3-L6, CK-4-L6 . And the differential genes between PagSUPa OE and CK groups were identified and compared, which helps to reveal the  molecular mechanism of PagSUPa directly suppresses the expression of phragmoplast orienting and positioning genes PagPOK1 and PagPOK2, and impairs cytokinesis and cell wall organization. Overall design: Gene expression profiling analysis of transcriptome data from PagSUPa OE plants leaves of Populus alba × P. glandulosa
