“…Our results also indicated that about 31.67 and 29.03% of PC genes were tandemly clustered in monocots maize and rice, respectively. And some stress responses were often associated with the PC proteins ( Ezaki et al, 2001 , 2005 ; Ozturk et al, 2002 ; Ma et al, 2011 ; Wu et al, 2011 ). Amplification of the PC genes by tandem duplication in monocots maize and rice is regarded as a mechanism for protecting plants from harmful stresses, which may be crucial for organismal adaptation to different environments.…”

“…Moreover, over-expression of AtBCB/AtSC3 could confer aluminum resistance in Arabidopsis ( Ezaki et al, 2001 , 2005 ). And BcBCP1 can enhance tolerance to osmotic stress when over-expressed in tobacco ( Wu et al, 2011 ). The differential expression profiles of different PC family genes may imply diverse roles of plant response to stress.…”

“…Previous studies have indicated that PCs are involved in various plant activities, including cell differentiation and reorganization ( Fedorova et al, 2002 ; Kato et al, 2002 ), pollen tube germinating and anther pollination ( Kim et al, 2003 ; Dong et al, 2005 ), reproductive potential determining ( Khan et al, 2007 ), apical buds organ development ( Mashiguchi et al, 2009 ), and somatic embryogenesis ( Poon et al, 2012 ), etc. In addition, PCs may also function in stress responses, including enhancing osmotic tolerance ( Wu et al, 2011 ), inhibiting aluminum absorption and protecting cell from aluminum toxicity ( Ezaki et al, 2001 , 2005 ). Several researches have indicated that salt and drought stresses can induce the expression of some PC genes, suggesting the potential response to abiotic stresses ( Ozturk et al, 2002 ; Ma et al, 2011 ).…”

Phytocyanins (PCs) are plant-specific blue copper proteins, which play essential roles in electron transport. While the origin and expansion of this gene family is not well-investigated in plants. Here, we investigated their evolution by undertaking a genome-wide identification and comparison in 10 plants: Arabidopsis, rice, poplar, tomato, soybean, grape, maize, Selaginella moellendorffii, Physcomitrella patens, and Chlamydomonas reinhardtii. We found an expansion process of this gene family in evolution. Except PCs in Arabidopsis and rice, which have described in previous researches, a structural analysis of PCs in other eight plants indicated that 292 PCs contained N-terminal secretion signals and 217 PCs were expected to have glycosylphosphatidylinositol-anchor signals. Moreover, 281 PCs had putative arabinogalactan glycomodules and might be AGPs. Chromosomal distribution and duplication patterns indicated that tandem and segmental duplication played dominant roles for the expansion of PC genes. In addition, gene organization and motif compositions are highly conserved in each clade. Furthermore, expression profiles of maize PC genes revealed diversity in various stages of development. Moreover, all nine detected maize PC genes (ZmUC10, ZmUC16, ZmUC19, ZmSC2, ZmUC21, ZmENODL10, ZmUC22, ZmENODL13, and ZmENODL15) were down-regulated under salt treatment, and five PCs (ZmUC19, ZmSC2, ZmENODL10, ZmUC22, and ZmENODL13) were down-regulated under drought treatment. ZmUC16 was strongly expressed after drought treatment. This study will provide a basis for future understanding the characterization of this family.

“…Overexpression of BcBCP1, a phytocyanin-related early nodulin-like gene from Boea crassifolia, in tobacco under the control of CaMV 35S promoter enhanced tolerance to osmotic stress, as indicated by the less impaired growth, less damaged membrane integrity and lower lipid peroxidation levels after osmotic stress (Wu et al, 2011). Transgenic tobacco lines overexpressing BcBCP1 showed higher photosynthetic rates, higher antioxidant enzyme activities and higher cytosyl ascorbic peroxidase transcription levels than non-transgenic tobacco plants, both under normal conditions and under osmotic stress.…”

Environmental stresses, both abiotic and biotic, are the main factors reducing crops productivity. Biotic stresses caused by fungi, viruses, bacteria and insects are the major threats. However, abiotic stresses have more adverse effects on crop yield and crop survival. Hitherto, tolerant plants were mainly produced by classical breeding techniques. Success in breeding for better adapted varieties to abiotic and biotic stresses depends on the concerted efforts of various research domains including plant and cell physiology, molecular biology, genetics and breeding. However, such process is time consuming. The production of transgenic plants by genetic engineering allows a much faster progress. This review focuses on stress tolerance on tobacco. Tolerance to salt, drought, water stress, low and high temperature, heavy metals, pathogens and pests were enhanced via overexpression of specific stress related genes from different sources.

“…Both ABA-dependent and -independent signal pathways have been revealed in the activation of gene expression. The genes encoding the protective proteins such as aldehyde dehydrogenase, heat shock factors and LEA proteins are thought to be regulated by ABA - directed signal pathways ( Kirch et al, 2001 ; Deng et al, 2006 ; Wu et al, 2011 ). Dehydration-triggered gene expression is regulated by a cascade of signaling molecules such as transcription factors, calmodulins, and kinases and phosphatases.…”

Vegetative tissues of Boea hygrometrica, a member of the Gesneriaceae family, can tolerate severe water loss to desiccated state and fully recover upon rehydration. Unlike many other so called “resurrection plants,” the detached leaves of B. hygrometrica also possess the same level of capacity for desiccation tolerance (DT) as that of whole plant. B. hygrometrica is distributed widely from the tropics to northern temperate regions in East Asia and grows vigorously in areas around limestone rocks, where dehydration occurs frequently, rapidly, and profoundly. The properties of detached B. hygrometrica leaves and relative ease of culture have made it a useful system to study the adaptive mechanisms of DT. Extensive studies have been conducted to identify the physiological, cellular, and molecular mechanisms underlying DT in the last decade, including specific responses to water stress, such as cell wall folding and pigment-protein complex stabilizing in desiccated leaves. In this review, the insight into the structural, physiological, and biochemical, and molecular alterations that accompany the acquisition of DT in B. hygrometrica is described. Finally a future perspective is proposed, with an emphasis on the emerging regulatory roles of retroelements and histone modifications in the acquisition of DT, and the need of establishment of genome sequence database and high throughput techniques to identify novel regulators for fully understanding of the matrix of DT.
