A good image editing model should learn to map the relationships between styles from different domains, cater to the high quality and diversity of the generated images, and be highly scalable across different domains. At the same time, given the importance of multi-device deployments, especially of models on lightweight devices, lightweight optimization of models is an essential and critical task. Based on these key points, a new approach to optimizing and improving existing base models, namely OMGD-StarGAN, is proposed by combining PatchGAN discriminators and DynamicD dynamic training strategies, ResNet style generators, and modulated convolution, based on online multi-granularity knowledge distillation algorithms and StarGAN v2. A comparison of various experiments is conducted, and the experimental results show that the proposed model reduces the computational cost while improving the quality and diversity of the generated images.

Many transcriptional factors including the R2R3-MYB domain, basic helix-loop-helix (bHLH) domain and WD40 repeat proteins, which regulate flavonoid biosynthesis, have been identified in various plant species. However, there is little information on WD40 proteins in underground organs. In this study, a WD40-repeat protein gene was isolated from purple-fleshed sweet potato ( Ipomoea batatas (L.) Lam. cv. Yamakawamurasaki) ( IbWD40). The expression patterns of this gene were positively correlated with anthocyanin accumulation in different sweet potato cultivars. An IbWD40-GFP fusion protein was observed only in the nucleus of onion epidermal cells, which was consistent with its role as a transcriptional regulator. Stable transformation analysis revealed that IbWD40 was up-regulated in Arabidopsis thaliana seedlings, which accumulated anthocyanins, with possible additional effects on the formation of other flavonoid compounds in other tissues. These results suggest that in storage roots of purple-fleshed sweet potato the activity of IbWD40 plays a critical role in the regulation of anthocyanin biosynthesis. [ABSTRACT FROM AUTHOR]
