“…In plants, RNA binding and processing proteins have so far only been implicated in floral transition and patterning, vegetative phase change, as well as abscisic acid signaling, stress responses, and circadian rhythms (Chen and Cheng, 2004). The putative RNA binding and processing protein TGH with its proposed role in vascularization adds a new biological function to this list.…”

“…In plants, pre-mRNA processing, alternative splicing, and other RNA-directed protein activities are required for various processes, including floral transition, floral patterning, vegetative phase change, and signal transduction (Chen and Cheng, 2004). However, little is known about the role of RNA binding and processing proteins when compared with the large set of proteins with a proposed role in these processes .…”

The Evolutionarily Conserved TOUGH Protein Is Required for Proper Development ofArabidopsis thaliana

et al. 2005

In this study, we characterize the evolutionarily conserved TOUGH (TGH) protein as a novel regulator required for Arabidopsis thaliana development. We initially identified TGH as a yeast two-hybrid system interactor of the transcription initiation factor TATA-box binding protein 2. TGH has apparent orthologs in all eukaryotic model organisms with the exception of the budding yeast Saccharomyces cerevisiae. TGH contains domains with strong similarity to G-patch and SWAP domains, protein domains that are characteristic of RNA binding and processing proteins. Furthermore, TGH colocalizes with the splicing regulator SRp34 to subnuclear particles. We therefore propose that TGH plays a role in RNA binding or processing. Arabidopsis tgh mutants display developmental defects, including reduced plant height, polycotyly, and reduced vascularization. We found TGH expression to be increased in the amp1-1 mutant, which is similar to tgh mutants with respect to polycotyly and defects in vascular development. Interestingly, we observed a strong genetic interaction between TGH and AMP1 in that tgh-1 amp1-1 double mutants are extremely dwarfed and severely affected in plant development in general and vascular development in particular when compared with the single mutants.

“…Proteins involved in the RNA processing and alternative splicing, RNA transport, messenger RNA (mRNA) translation, mRNA stability, and mRNA silencing mechanisms have been shown to be required for normal plant development and the responses of plants to altered environments [86][87]. In our case, just the glycine-rich RNA-binding protein was differentially found after DIGE analysis, and this protein correlated to ROS production according to different articles [88,89].…”

“…FY binds to its tryptophantryptophan (WW) protein interaction domain . The Arabidopsis genome encodes many RNA-binding proteins, including 198 that possess the most common RNA-binding protein domains and half of these RRM-containing proteins are uncharacterized and plant-specific (Cheng and Chen 2004). Several plant RNA-binding proteins have been studied.…”

Overexpression of the rFCA RNA Recognition Motif Affects Morphologies Modifications in Rice (Oryza sativa L.)

et al. 2007

RNA recognition motifs as important regulators of gene expression are highly conserved in animals and plants. The FCA floral promotion gene in Arabidopsis encodes a protein, containing two RNA recognition motifs (RRM) and a WW protein interaction domain. Here we isolated FCA cDNA from rice. FCA in rice (rFCA) was homologous to FCA-gamma of Arabidopsis and contained conserved domains. To investigate the function of RRM domain, fragment RRM1 and RRM2 of rFCA were introduced into rice subspecies Oryza sativa L. subsp. Indica var. 9311 and another rice subspecies Oryza sativa L. subsp. Japonica var. zhonghua11 transformation. Two transgenic lines exhibited similar phenotypes, flowering time delay, seed size and cell volume of transgenic plants was increased. These results showed that constitutive expression of RRMs could regulate cellular size. The patterns of overexpression of two RRM domains and their similar morphologies indicate they may play a same role.
