The present study investigated rice leaf proteome in response to heat stress. Rice seedlings were subjected to a temperature of 42 degrees C and samples were collected 12 and 24 h after treatment. Increased relative ion leakage and lipid peroxidation suggested that oxidative stress frequently was generated in rice leaves exposed to high temperature. 2-DE,(More)
While the phytotoxic responses of arsenic (As) on plants have been studied extensively, based on physiological and biochemical aspects, very little is known about As stress-elicited changes in plants at the proteome level. Hydroponically grown 2-wk-old rice seedlings were exposed to different doses of arsenate, and roots were collected after 4 days of(More)
The contribution of SOS1 (for Salt Overly Sensitive 1), encoding a sodium/proton antiporter, to plant salinity tolerance was analyzed in wild-type and RNA interference (RNAi) lines of the halophytic Arabidopsis (Arabidopsis thaliana)-relative Thellungiella salsuginea. Under all conditions, SOS1 mRNA abundance was higher in Thellungiella than in Arabidopsis.(More)
Protein N-glycosylation in the endoplasmic reticulum (ER) and in the Golgi apparatus is an essential process in eukaryotic cells. Although the N-glycosylation pathway in the ER has been shown to regulate protein quality control, salt tolerance, and cellulose biosynthesis in plants, no biological roles have been linked functionally to N-glycan modifications(More)
A comparative proteomic approach has been adopted in combination with physiological and biochemical analysis of tomato leaves responding to waterlogging stress. Waterlogging resulted in increases of relative ion leakage, lipid peroxidation and in vivo H2O2 content, whereas the chlorophyll content was decreased. Histocytochemical investigations with(More)
Seed germination is a complex physiological process in plants that can be affected severely by heavy metals. The interference of germination by cadmium stress has not been well documented at the proteomic level. In the present study, in order to investigate the protein profile alternations during the germination stage following exposure to cadmium, a(More)
Roots are highly sensitive organs in plants. To gain a better knowledge of the chilling stress responses of plants, it is imperative to analyze the tissue-specific proteome patterns under chilling stress. In the present study, two-dimensional gel electrophoresis (2-DE) coupled with mass spectrometry, has been adopted to investigate the protein expression(More)
To gain a better understanding of the tomato root response to waterlogging stress at protein level, a proteomic approach has been conducted in combination with physiological analyses. Five-week old plants were subjected to waterlogging stress, and roots were collected 24 and 72 h after treatment. Waterlogging stress resulted in a gradual increase of lipid(More)
Glyphosate is one of the most widely used herbicides in cereal-growing regions worldwide. In the present work, the protein expression profile of rice leaves exposed to glyphosate was analyzed in order to investigate the alternative effects of glyphosate on plants. Two-week-old rice leaves were subjected to glyphosate or a reactive oxygen species (ROS)(More)
Rab7 is a small GTP-binding protein important in early to late endosome/lysosome vesicular transport in mammalian cells. We have isolated a Rab7 cDNA clone, OsRab7, from a cold-treated rice cDNA library by the subtraction screening method. The cDNA encodes a polypeptide of 206 amino acids with a calculated molecular mass of about 23 kDa. Its predicted amino(More)
