Some C2H2 zinc-finger proteins (ZFP) transcription factors are involved in the development of pollen in plants. In grapevine (Vitis vinifera L.), it has been suggested that abnormalities in pollen development lead to the phenomenon called parthenocarpy that occurs in some varieties of this cultivar. At present, a network involving several transcription factors types has been revealed and key roles have been assigned to members of the C2H2 zinc-finger proteins (ZFP) family in model plants. However, particularities of the regulatory mechanisms controlling pollen formation in grapevine remain unknown. In order to gain insight into the participation of ZFPs in grapevine gametophyte development, we performed a genome-wide identification and characterization of genes encoding ZFP (VviZFP family). A total of 98 genes were identified and renamed based on the gene distribution into grapevine genome. The analysis performed indicate significant changes throughout VviZFP genes evolution explained by high heterogeneity in sequence, length, number of ZF and presence of another conserved domains. Moreover, segmental duplication participated in the gene family expansion in grapevine. The VviZFPs were classified based on domain and phylogenetic analysis into three sets and different groups. Heat-map demonstrated differential and tissue-specific expression patterns of these genes and k-means clustering allowed to identify a group of putative orthologs to some ZFPs related to pollen development. In transgenic plants carrying the promVviZFP13::GUS and promVviZFP68::GUS constructs, GUS signals were detectable in the anther and mature pollen grains. Expression profiling of selected VviZFP genes showed differential expression pattern during flower development and provides a basis for deepening in the understanding of VviZFPs role on grapevine reproductive development.

Abstract Background: CCCTC-Binding Factor (CTCF), also known as 11-zinc finger protein, participates in many cellular processes, including insulator activity, transcriptional regulation and organization of chromatin architecture. Based on single cell flow cytometry and single cell RNA-FISH analyses, our previous study showed that deletion of CTCF binding site led to a significantly increase of cellular variation of its target gene. However, the effect of CTCF on genome-wide landscape of cell-to-cell variation is unclear. Results: We knocked down CTCF in EL4 cells using shRNA, and conducted single cell RNA-seq on both wild type (WT) cells and CTCF-Knockdown (CTCF-KD) cells using Fluidigm C1 system. Principal component analysis of single cell RNA-seq data showed that WT and CTCF-KD cells concentrated in two different clusters on PC1, indicating gene expression profiles of WT and CTCF-KD cells were systematically different. Interestingly, GO terms including regulation of transcription, DNA binding, Zinc finger and transcription factor binding were significantly enriched in CTCF-KD-specific highly variable genes, indicating tissue-specific genes such as transcription factors were highly sensitive to CTCF level. The dysregulation of transcription factors potentially explain why knockdown of CTCF lead to systematic change of gene expression. In contrast, housekeeping genes such as rRNA processing, DNA repair and tRNA processing were significantly enriched in WT-specific highly variable genes, potentially due to a higher cellular variation of cell activity in WT cells compared to CTCF-KD cells. We further found cellular variation-increased genes were significantly enriched in down-regulated genes, indicating CTCF knockdown simultaneously reduced the expression levels and increased the expression noise of its regulated genes. Conclusions: To our knowledge, this is the first attempt to explore genome-wide landscape of cellular variation after CTCF knockdown. Our study not only advances our understanding of CTCF function in maintaining gene expression and reducing expression noise, but also provides a framework for examining gene function.
