To this end, an improved Sparrow and Eagle Optimization Algorithm (HS-SBOA) is proposed. Initially, the algorithm employs Iterative Mapping to generate an initial sparrow and eagle population, enhancing the diversity of the population during the global search phase. Subsequently, an adaptive weighting strategy is introduced during the exploration phase of the algorithm to achieve a balance between exploration and exploitation. Finally, to avoid the algorithm falling into local optima, a Cauchy mutation operation is applied to the current best individual. To validate the performance of the HS-SBOA algorithm, it was applied to the CEC2021 benchmark function set and three practical engineering problems, and compared with other optimization algorithms such as the Grey Wolf Optimization (GWO), Particle Swarm Optimization (PSO), and Whale Optimization Algorithm (WOA) to test the effectiveness of the improved algorithm. The simulation experimental results show that the HS-SBOA algorithm demonstrates significant advantages in terms of convergence speed and accuracy, thereby validating the effectiveness of its improved strategies.展开更多

Among them, we found that 122 of these proteins contained the highly conserved pathogenic-related host-targeting-motif RxLx within 100 residues adjacent to the signal peptide cleavage site. According to PEDNAT and COG of the GenBank database, the functions of this motif containing proteins included metabolism modification and cell secretion. We blasted them in GenBank and found 47.54% had highly conserved homologues in other species, among them 74.1% had putative functional domains. This suggests these proteins are presumably ancient and vertically transmitted within the species. Many of these domains belonged to proteins which played roles in the pathogenic process of other kinds of pathogens and some had already been proved to be pathogenic secretary proteins of Botrytis cinerea. So we postulated that proteins contained host-targeting-motif RxLx were candidates participating in the pathogenesis of Botrytis cinerea.展开更多
