2024年6月13日 · We identify OsGATA8 -H as a high-NUE haplotype with enhanced nitrogen uptake and a higher proportion of productive tillers. The geographical distribution of OsGATA8- H and its frequency change in...

2024年6月13日 · OsGATA8通过调节参与胁迫耐受、活性氧清除和叶绿素生物合成关键基因的表达，整合多个细胞过程，包括K + /Na + 含量、光合效率、相对含水量、Fv/Fm比率和亚细胞器的稳定性。 对照条件下， OsGATA8 过表达株系 (OE)在苗期和成熟期相比野生型 (WT)和敲低系 (KD)表现出更旺盛的生长。 OE系的根更多更长，OE和WT幼苗的鲜重显著高于KD。 成熟期OE系的叶绿素含量显著更高，单株穗数、每穗粒数、每穗实粒数、单株产量和千粒重增加，而敲除系相反 …

GATA转录因子是一类广泛存在于真核生物中的转录因子,在植物光响应调控,叶绿素合成,细胞分裂素响应以及碳,氮代谢等生物学过程中发挥重要作用,这些生物学过程与作物产量息息相关,对GATA家族的研究可以为作物增产提供一定的理论基础.GATA转录因子具有特殊的锌指结构,而且根据前人对拟南芥,蓖麻,水稻等植物的研究发现,锌指结构的大部分氨基酸位点在大部分成员中是高度保守的.本研究主要对GATA转录因子的特异结构,分类,进化分析以及生物学功能进行论述.通过 …

2023年12月2日 · GATA transcription factors are type IV zinc-finger proteins that play key roles in plant growth and responses to environmental stimuli. Although these proteins have been studied in model plants, the related studies of GATA gene family under abiotic stresses are rarely reported in grapevine (Vitis vinifera L.).

2021年8月16日 · GATA transcription factors (TFs) are widespread eukaryotic regulators whose DNA-binding domain is a class IV zinc finger motif (CX 2 CX 17–20 CX 2 C) followed by a basic region. We identified 262...

2019年10月1日 · Here, we review the results of genome-wide studies of GATA factor occupancy in human and murine cell lines and primary cells (as determined by chromatin immunoprecipitation sequencing), and then discuss the molecular mechanisms underlying the mediation of transcriptional and epigenetic regulation by GATA factors.

2012年9月20日 · GATA is a graphic alignment tool for comparative sequence analysis. It makes use of BLAST to graphically align two DNA sequences, creating box- line- box representations of window scored local alignments. GATA also displays extensive GFF gene annotation.

This review focuses on the role of GATA transcription factors in carcinogenesis. GATA factors are zinc finger DNA binding proteins that control the development of diverse tissues by activating or repressing transcription. GATA factors thus coordinate cellular maturation with proliferation arrest and cell survival.
