Pre-mRNA alternative splicing is a conserved mechanism for eukaryotic cells to leverage existing genetic resources to create a diverse pool of protein products. It is regulated in coordination with other events in RNA metabolism such as transcription, polyadenylation, RNA transport, and
Certain plant varieties typically require prolonged exposure to the cold of winter to become competent to flower rapidly in the spring. This process is known as vernalization. In Arabidopsis thaliana, vernalization renders plants competent to flower by epigenetically silencing the strong floral
The bacterial plant pathogen Pseudomonas syringae pv. tomato DC3000 (DC3000) causes disease in Arabidopsis thaliana and tomato plants, and it elicits the hypersensitive response in nonhost plants such as Nicotiana tabacum and Nicotiana benthamiana. While these events chiefly depend upon the type III
In this study, the structural elements in the putative movement protein (MP) of the GAV strain of Barley yellow dwarf virus (BYDV-GAV) were investigated. The GFP fusion protein of BYDV-GAV MP was found to be associated with the nuclear envelope (NE) in transgenic Arabidopsis thaliana (L.) cells.

ArabidopsisProtein arginine methyltransferase 10 (PRMT10) is a type I arginine methyltransferase that is essential for regulating flowering time in Arabidopsis thaliana. We present a 2.6 Å resolution crystal structure of A. thaliana PRMT 10 (AtPRMT10) in complex with a reaction product, S-adenosylhomocysteine.
Twin-arginine targeting (Tat) protein secretion systems consist of two protein types, members of the TatA and TatC families. Homologues of these proteins are found in many archaea, bacteria, chloroplasts and mitochondria. Every prokaryotic organism with a fully sequenced genome exhibits either
Human PROTEIN ARGININE METHYLTRANSFERASE5 (PRMT5) encodes a type II protein arginine (Arg) methyltransferase and its homologs in animals and yeast (Saccharomyces cerevisiae and Schizosaccharomyces pombe) are known to regulate RNA processing, signal transduction, and gene expression. However, PRMT5
Biotechnological uses of plant cell-tissue culture usually rely on constitutive transgene expression. However, such expression of transgenes may not always be desirable. In those cases, the use of an inducible promoter could be an alternative approach. To test this hypothesis, we developed two
BACKGROUND
Arginine and citrulline serve as nitrogen storage forms, but are also involved in biosynthetic and catabolic pathways. Metabolism of arginine, citrulline and ornithine is distributed between mitochondria and cytosol. For the shuttle of intermediates between cytosol and mitochondria
Arginine methylation of histone H3 and H4 plays important roles in transcriptional regulation in eukaryotes such as yeasts, fruitflies, nematode worms, fish and mammals; however, less is known in plants. In the present paper, we report the identification and characterization of two Arabidopsis
Nitric oxide (NO) is a key signaling molecule in plants, regulating a wide range of physiological processes. However, its origin in plants remains unclear. It can be generated from nitrite through a reductive pathway, notably via the action of the nitrate reductase (NR), and evidence suggests an
The PII proteins are key mediators of the cellular response to carbon and nitrogen status and are found in all domains of life. In eukaryotes, PII has only been identified in red algae and plants, and in these organisms, PII localizes to the plastid. PII proteins perform their role by assessing
Polyamine biosynthesis starts with putrescine production through the decarboxylation of arginine or ornithine. In Arabidopsis thaliana, putrescine is synthesised exclusively by arginine decarboxylase (ADC), which exists as two isoforms (ADC1 and 2) that are differentially regulated by abiotic
CARM1/PRMT4 (for COACTIVATOR-ASSOCIATED ARGININE METHYLTRANSFERASE1/PROTEIN ARGININE METHYLTRANSFERASE4) catalyzes asymmetric dimethylation on arginine (Arg), and its functions in gene regulation is understood only in animal systems. Here, we describe AtPRMT4a and AtPRMT4b as a pair of Arabidopsis
