A comparative analysis on protein kinases encoded in the completely sequenced genomes of two plant species, namely Arabidopsis thaliana and Oryza sativa spp japonica cv. Nipponbare is reported in the current study. We have analysed 836 and 1386 kinases identified from A. thaliana and the O. sativa

11 Cystatin genes in rice were identified, and their expression patterns were comprehensively analyzed, which reveals multiple roles in both seed development and plant response to environmental variations. Cystatin is a group of small proteins and known to inhibit the activities of
As a highly reduced organism, pollen performs specialized functions to generate and carry sperm into the ovule by its polarily growing pollen tube. Yet the molecular genetic basis of these functions is poorly understood. Here, we identified 322 unique proteins, most of which were not reported
A rice pse(t) (premature senescence, tentatively) mutant line, was isolated from 4,500 independent T-DNA inserted transgenic lines. The symptoms of premature senescence appeared more severely than those of the control plants (Zhonghua 11, japonica) at the last development stage. To characterize the
Two semidwarfism-related proteins, SRP-1 and SRP-2, were detected as major spots in a long-culm rice cultivar, Norin 29 and its semidwarf near-isogenic line, SC-TN1, respectively, by two-dimensional gel electrophoresis (2D-PAGE). The testcross showed that SRP-1 and SRP-2 are controlled by codominant
Metacaspases are distant relatives of animal caspases found in plants, protozoa and fungi. Some recent studies have demonstrated that metacaspases are involved in regulating the developmental and environmentally induced programmed cell death in plants. In this study, we identified metacaspase gene
Mitochondrial protein import is a complex multistep process from synthesis of proteins in the cytosol, recognition by receptors on the organelle surface, to translocation across one or both mitochondrial membranes and assembly after removal of the targeting signal, referred to as a presequence. In
Understanding the genetic basis of reproductive barriers between species has been a central issue in evolutionary biology. The S1 locus in rice causes hybrid sterility and is a major reproductive barrier between two rice species, Oryza sativa and Oryza glaberrima The O. glaberrima-derived allele
Using particle bombardment-mediated transformation, a codon-optimized synthetic gene for human lysozyme was introduced into the calli of rice (Oryza sativa) cultivar Taipei 309. The expression levels of recombinant human lysozyme in the transformed rice suspension cell culture approached
Engineering biological nitrogen fixation in eukaryotic cells by direct introduction of nif genes requires elegant synthetic biology approaches to ensure that components required for the biosynthesis of active nitrogenase are stable and expressed in the appropriate stoichiometry. Previously,
The plant-parasitic nematode Meloidogyne graminicola causes considerable damages to rice (Oryza sativa) culture. Resistance to M. graminicola in the related species Oryza glaberrima reduces root penetration by juveniles and stops further nematode development. M.
Serine carboxypeptidase-like (SCPL) proteins have recently emerged as a new group of plant acyltransferases. These enzymes share homology with peptidases but lack protease activity and instead are able to acylate natural products. Several SCPL acyltransferases have been characterized to date from
Endoplasmic reticulum-associated protein degradation (ERAD) plays an important role in endoplasmic reticulum (ER) quality control. To date, little is known about the retrotranslocation machinery in the plant ERAD pathway. We obtained a DERLIN-like protein (OsDER1) through a SWATH-based quantitative
