Apoplastic ascorbate oxidase (AO) plays a major role in cell growth. Although AO genes have been studied in depth, some articles have mistakenly identified AO homologues as AO genes. Overall, the divergence between AO genes and AO homologues has not been explored. Meanwhile, there is little information concerning AO and the AO homologue with respect to Camellia sinensis. In the present study, one CsAO homologue and three CsAOs were confirmed by RT-PCR amplification, cloning and sequencing. Multicopper oxidase type 1 (PF00394), type 2 (PF07731) or type 3 (PF07732) domains and one transmembrane helix were the key domains for each member of the cupredoxin family. The CsAOs with their counterparts from seven dicotyledonous plants and three monocotyledonous plants were used to build phylogenetic tree and compare the deduced polypeptides. CsAO may be strongly expressed in the stretch expanded tissues, including bud and root. The abiotic stress-induced expression pattern of the CsAO homologue (CsAO2) is similar to those of CsAO1, CsAO3 and CsAO4. A new and very large group of AO homologues, which may function as AO genes, was present in both dicotyledonous and monocotyledonous plants. Our study may help in identifying stress-responsive AO genes of plants. 相似文献

Tea (Camellia sinensis L.) is well known for its biochemical constituents that define the product quality and confer pest and disease resistance. Seven major metabolites – epicatechin (EC), epicatechin gallate (ECg), epigallocatechin (EGC), epigallocatechin gallate (EGCg), caffeine, theobromine, and gallic acid – of 87 beverage type and six non-beverage type tea accessions from Sri Lankan tea germplasm were profiled using HPLC and LC-MS/MS. All seven metabolites varied widely in the beverage type accessions. The non-beverage types only contained gallic acid and epicatechin. Results prove the presence of high EC and ECg contents in green leaves to be a reliable marker for identifying high-quality black tea-producing accessions. High EC and low EGCg contents in green tea leaves appear to enhance traits of resistance to blister blight disease. Significant variations detected in theobromine, caffeine, and total polyphenol content define the affinity of germplasm to the main three tea taxa, and we conclude that C. sinensis ssp. lasiocalyx predominates the Sri Lankan germplasm collection. 相似文献

The efficiency of different temperature cycles in inducing budburst of one-year-old shoots of the apricot cultivar ‘Palsteyn’ from dormancy was evaluated. Three replications of shoots were collected during two consecutive years from adult trees, following the accumulation of different amounts of chilling in the field. Thereafter, shoots were exposed to different temperature cycles in growth chambers, for 60 days. The temperature treatments included a continuous temperature of 5 °C; daily temperature cycles of 19/5 h at 5/15 °C, at 5/20 °C, and at 5/25 °C; and the same temperature cycles for the remainder of the 60-day period, after pretreatment at 5 °C for 30 or 45 days. After the temperature treatments, shoots were forced at 25 °C until budburst. The mean time to budburst (MTB) (in days) of lateral vegetative, terminal vegetative and reproductive buds was evaluated. The efficiency of the different treatments was greatly influenced by the date on which shoots were cut. High temperatures had a more positive effect on the reduction of MTB when chilling accumulation had occurred in the field instead of the growth chamber. After partial chilling accumulation in the field, high temperatures (25 °C) combined with low temperatures are more efficient than cycles of moderate temperatures (15 or 20 °C) to induce an earlier budburst. In view of these results, a parallel accumulation of both chilling and heat requirements after partial chilling accumulation is suggested. The application of these results could assist in the development of more accurate models for the prediction of the overcoming of dormancy and blooming. 相似文献

Root restriction often depresses photosynthetic capacity and the mechanism for this reduction, however, remains unclear. To identify the mechanism by which root restriction affects the photosynthetic characteristics, tomato (Lycopersicon esculentum Mill.) seedlings were subjected to root restriction stress with or without supplemental aeration to the nutrient solution. With the development of the root restriction stress, CO2 assimilation rate was decreased only in confined plants without supplemental aeration. There were also significant decreases in leaf water potential, stomatal conductance (gs), intercellular CO2 concentration (Ci), and increases in the stomatal limitation (l) and the xylem sap ABA concentration. Meanwhile, the maximum carboxylation rate of Rubisco (Vcmax) and the capacity for ribulose-1,5-bisphosphate regeneration (Jmax) also decreased, followed by substantial reductions in the quantum yield of PSII electron transport (ΦPSII). Additionally, root restriction resulted in accumulation of carbohydrates in various plant tissues irrespective of aeration conditions. It is likely that root restriction-induced depression of photosynthesis was mimicked by water stress. 相似文献
