Trachyspermum ammi (L.) Sprague (Ajowan) is an endangered medicinal plant with useful pharmaceutical properties. Ex situ conservation of this medicinal plant needs the development of an in vitro regeneration protocol using somatic embryogenesis. In the present study, a high-precision image-processing approach was successfully applied to measure physical properties of embryogenic callus. Explant age and the concentrations of 2,4-dichlorophenoxyacetic acid (2,4-D), kinetin (Kin), and sucrose were used as inputs, and an artificial intelligence technique was applied to predict physical properties of embryogenic callus, and the number of somatic embryos produced. Artificial neural network (ANN) models were tested to find the best combinations of input variables that affected output variables. The lower values of root mean square error, and mean absolute error, and the highest values of determination coefficient, were achieved when all four input variables were applied to predict the number of somatic embryos, the area of the callus, the perimeter of the callus, the Feret diameter of the callus, the roundness of the callus, and the true density of the callus in ANN models. The highest measured and predicted number of somatic embryos were achieved from the interaction of 15-d-old explants?×?1.5 mg L?1 2,4-D?×?0.5 mg L?1 Kin?×?2.5% (w/v) sucrose. Based on sensitivity analysis, the 2,4-D concentration was the most important component in the culture medium that affected the number of somatic embryos and physical properties of the embryogenic callus tissue. 相似文献

Cyclophilins (CYPs) belong to the immunophilin superfamily, having the peptidyl prolyl cis/trans isomerase activity that can catalyze the cis/trans isomerisation process of proline residues. Previous studies have shown their importance in plants, but no comprehensive analysis of maize CYP family has been reported. In the present study, a whole-genome-wide analysis of maize CYP family was performed and 39 ZmCYP genes (ZmCYP1 to ZmCYP39) were identified from maize genome, which were unequally distributed on maize ten chromosomes. Phylogenetic analysis revealed a weak relationship among these ZmCYP genes. Furthermore, their gene structure and motif patterns also displayed variant within the gene family. Four segmental and one tandem duplicated gene pairs were found from 39 ZmCYP genes, respectively, indicating their roles in the expansion of maize CYP family. Expression analysis of 39 ZmCYP genes in maize tissues showed their differential tissue specific expression patterns. Quantitative real-time PCR analysis of 19 selected ZmCYP genes under salinity stress indicated their stress-inducible expression profile. Heterologous expression of ZmCYP15 in E. coli enhanced tolerance against abiotic stress. Subcellular localization analysis indicated ZmCYP15 was located in nucleus and cytoplasm. Our study describes the importance of the maize CYP gene family in stress response, and provides a reference for future study and application for maize genetic improvement. 相似文献
