Identification and characterization of a salt stress-inducible zinc finger protein from Festuca arundinacea

Ergovaline levels in cultivars of Festuca arundinacea

Overexpression of a zinc-finger protein gene from rice confers tolerance to cold, dehydration, and salt stress in transgenic tobacco.

Stress perception and signal transduction leading to tolerance involve a complex interplay of different gene products. We describe here the isolation and characterization of an intronless gene (OSISAP1) from rice encoding a zinc-finger protein that is induced after different types of stresses, namely cold, desiccation, salt, submergence, and heavy metals as well as injury. The gene is also indu...

The Arabidopsis Gene zinc finger protein 3(ZFP3) Is Involved in Salt Stress and Osmotic Stress Response

Plants are continuously challenged by various abiotic and biotic stresses. To tide over these adversities, plants evolved intricate regulatory networks to adapt these unfavorable environments. So far, many researchers have clarified the molecular and genetic pathways involved in regulation of stress responses. However, the mechanism through which these regulatory networks operate is largely unk...

The mRNAs associated to a zinc finger protein from Trypanosoma cruzi shift during stress conditions

Trypanosome gene expression is regulated almost exclusively at the posttranscriptional level, through mRNA stability, storage and degradation. Here, we characterize the ribonucleoprotein complex (mRNPs) corresponding to the zinc finger protein TcZC3H39 from T. cruzi comparing cells growing in normal conditions and under nutritional stress. The nutritional stress is a key step during T. cruzi di...

A growth factor-inducible gene encodes a novel nuclear protein with zinc finger structure.

Growth factors rapidly induce numerous genes that encode regulatory proteins, many of which have been identified by cDNA cloning. In this study, differential hybridization was used to screen a cDNA library constructed from human mammary carcinoma MDA-468 cells that were stimulated with transforming growth factor beta-1 (TGF-beta 1) in the presence of cycloheximide. One of the cDNA clones that w...
