“…The first plant VDAC was identified electrophysiologically in purified outer membranes of pea mitochondria (Schmid et al, 1992). Since then, mitochondrial porins have been isolated and characterised from several plant species (Aljamal et al, 1993;Blumenthal et al, 1993;Abrecht et al, 2000a,b;Godbole et al, 2003;Wandrey et al, 2004).…”

Chloroplasts, unique organelles of plants, originated from endosymbiosis of an ancestor of today's cyanobacteria with a mitochondria-containing host cell. It is assumed that the outer envelope membrane, which delimits the chloroplast from the surrounding cytosol, was thus inherited from its Gram-negative bacterial ancestor. This plastid-specific membrane is thus equipped with elements of prokaryotic and eukaryotic origin. In particular, the membrane-intrinsic outer envelope proteins (OEPs) form solute channels with properties reminiscent of porins and channels in the bacterial outer membrane. OEP channels are characterised by distinct specificities for metabolites and a quite peculiar expression pattern in specialised plant organs and plastids, thus disproving the assumption that the outer envelope is a non-specific molecular sieve. The same is true for the outer membrane of Gramnegative bacteria, which functions as a permeability barrier in addition to the cytoplasmic membrane, and embeds different classes of channel pores. The channels of these prokaryotic prototype proteins, ranging from unspecific porins to specific channels to ligand-gated receptors, are exclusively built of b-barrels. Although most of the OEP channels are formed by b-strands as well, phylogeny based on sequence homology alone is not feasible. Thus, the comparison of structural and functional properties of chloroplast outer envelope and bacterial outer membrane channels is required to pinpoint the ancestral OEP 'portrait gallery'.

“…Furthermore, no signal peptide and subcellular localization were predicted except that OsVDAC7 and OsVDAC8 encode a chloroplast transit peptide. In plants, VDACs are located not only in mitochondria but also in other cellular regions (Wandrey et al, 2004;Tateda et al, 2011). Although all 8 OsVDACs have typical transmembrane beta-strands based on the predictions of PRED-TMBB and BOCTOPUS (data not shown), further research on these VDAC genes is required to reveal their subcellular localizations and specific functions.…”

“…In plants, VDAC genes are expressed in an organ-specific manner and differential expression of VDAC genes during development has been reported (Al Bitar et al, 2002Bitar et al, , 2003Clausen et al, 2004;Wandrey et al, 2004). Moreover, the expression of VDAC genes can be affected by different stresses, including drought, heat shock, salinity, and defense against pathogens (Wang et al, 2006;Desai et al, 2006;Tateda et al, 2009Tateda et al, , 2011.…”

“…However, recent research has highlighted that in animals, plants, and yeasts there are significant functional differences between VDAC isoforms Tateda et al, 2011). At least three isoforms of VDAC are present in Nicotiana tabacum ) and five different VDACs are present in Arabidopsis thaliana, Lotus japonicus, and Medicago truncatula (Clausen et al, 2004;Wandrey et al, 2004;Lee et al, 2009). There are 4 VDACs reported in Oryza sativa (Roosens et al, 2000;Al Bitar et al, 2002Godbole et al, 2011).…”

ABSTRACT. The voltage-dependent anion channel (VDAC), also known as a mitochondrial porin, plays an important role in the regulation of metabolic and energetic functions of mitochondria, as well as in mitochondria-mediated apoptosis. Cytoplasmic male sterility (CMS) is of major economic importance for commercial hybrid production and a research model for the interaction between nuclear and cytoplasmic genomes. Recent research has revealed that CMS is associated with programmed cell death. Here, we used the Honglian (HL)-CMS line of rice (Oryza sativa) as material to investigate the association of O. sativa VDAC (OsVDAC) expression to CMS. Eight VDACs were extracted from rice in this study. Bioinformatic analysis of the rice VDACs was conducted at the DNA, cDNA, and protein level. Expression patterns of OsVDACs were analyzed in different organs and during different stages of pollen development using sterile line YuetaiA (YTA), and its maintainer line YuetaiB (YTB). Differential expression of OsVDACs between YTA and YTB was observed, suggesting that VDACs may be involved in the formation of HL-CMS.

“…They are localized in outer membranes of mitochondria and in plastids in eukaryotes (Benz, 1994;Fischer et al, 1994). One important family of these proteins is the voltagedependent anion channel (VDAC) family in eukaryotes (Wandrey et al, 2004). In Arabidopsis five VDAC isoforms (Clausen et al, 2004) and in rice three isoforms were identified (Roosens et al, 2000).…”

IntroductionCold stresses including chilling (<20 °C) and freezing (<0 °C) temperatures negatively affect plant growth and development and seed production. Plants struggle with cold stress by improving stress tolerance (Bray et al., 2000;Chinnusamy et al., 2007). Chilling decreases the membrane fluidity by causing the impairment of unsaturated membrane lipids and freezing temperatures lead to membrane damage by severe cellular dehydration, associated with ice formation (Wang et al., 2006;Solanke and Sharma, 2008). In the cold stress pathway, cytosolic Ca 2+ is considered as an important second messenger in low-temperature signal transduction (Figure 1). Calmodulin (CaM), CaM domain-containing protein kinases (CDPKs), calcineurin B-like proteins (CBLs), and CBL-interacting protein kinases (CIPKs) are among the major Ca 2+ sensors in plants (Solanke and Sharma, 2008). Thanks to microarray technologies, a large number of cold stress-responsive genes have been identified in various plant species. These genes include three main groups: 1) signaling components (protein kinases and transcription factors), 2) functional components (enzymes in metabolic pathways, aquaporins, etc.), and 3) small noncoding RNAs, namely micro-RNAs (miRNAs) (Shen et al., 2014;Koc et al., 2015a). Moreover, many transcription factor genes, including the WRKY family, DRE-binding protein (DREB) family, zinc-finger family, ethylene-responsive element binding factor (ERF) family, MYB family, basic helix-loop-helix (bHLH) family, basic-domain leucine zipper (bZIP) family, NAC family, and homeodomain transcription factor families and retrotransposons are also activated with harsh stress conditions (Shinozaki et al., 2003;Koc et al. 2015b). A class of DREB/CBF transcription factors, which bind to DRE/CRT cis-elements in the promoter regions of target genes, is commonly known for pathways in cold-inducible genes (Maruyama et al., 2009). Recent studies of Arabidopsis thaliana have also demonstrated the importance of DREB/CBF transcription factors in cold stress. In addition, ICE1, MYB15, and CAMTA3 proteins have been identified as regulators of DREB1/CBF gene expression (Chinnusamy et al., 2007;Doherty et al., 2009). Thus, biotic/abiotic stress conditions in plants cause significant changes in global gene expression. In A. thaliana, it has been reported that nearly 30% of the transcriptome is regulated by abiotic stress, and 2409 genes have been determined to have considerable Abstract: Cold stress is a major environmental factor in plant life cycles. Nicotiana benthamiana, which belongs to the family Solanaceae, is one of the most commonly used model species in plant-microbe interaction studies. In total, 5205 differentially expressed genes were identified under cold stress in N. benthamiana. Of these, 5029 were upregulated and 176 were downregulated within four time periods (4 h, 12 h, 24 h, and 48 h). The common up-and downregulated genes were identified as 692 and 6, respectively. The functional annotations of these genes were studied and these comm...
