The rapid development of low-bandgap(LBG)nonfullerene acceptors and wide-bandgap(WBG)copolymer donors in recent years has boosted the power conversion efficiency(PCE)of organic solar cells(OSCs)to the 18%level[1−21].The commercialization of OSCs is highly ***,critical issues like the cost and the stability also determine whether OSCs can enter the market or not[22].

Venation is a common anthocyanin pattern displayed in flowers that confers important ornamental traits to *** anthocyanin-related R2R3-MYB transcription factor,DPL,has been proposed to regulate corolla tube venation in petunia ***,however,we provide evidence redefining the role of DPL in petunia.A CRISPR/Cas9-mediated mutation of DPL resulted in the absence of the vein-associated anthocyanin pattern above the abaxial surface of the flower bud,but not corolla tube venation,thus indicating that DPL did not regulate the formation of corolla tube ***,quantitative real-time PCR analysis demonstrated that the spatiotemporal expression pattern of another R2R3-MYB gene,AN4,coincided with the formation of corolla tube venation in ***,overexpression of AN4 promoted anthocyanin accumulation by increasing the expression of anthocyanin biosynthesis ***/Cas9-mediated mutation of AN4 led to an absence of corolla tube venation,suggesting that this gene in fact determines this key plant *** together,the results presented here redefine the prime regulator of corolla tube venation,paving the way for further studies on the molecular mechanisms underlying the various venation patterns in petunia.

Microsporidia are obligate intracellular parasites with rigid spore walls that protect against various environmental pressures. Despite an extensive description of the spore wall, little is known regarding the mechanism by which it is deposited or the role it plays in cell adhesion and infection. In this study, we report the identification and characterization of two novel spore wall proteins, SWP7 and SWP9, in the microsporidian species Nosema bombycis. SWP7 and SWP9 are mainly localized to the exospore and endospore of mature spores and the cytoplasm of sporonts, respectively. In addition, a portion of SWP9 is targeted to the spore wall of sporoblasts earlier than SWP7 is. Both SWP7 and SWP9 are specifically colocalized to the spore wall in mature spores. Furthermore, immunoprecipitation, far-Western blotting, unreduced SDS-PAGE, and yeast two-hybrid data demonstrated that SWP7 interacted with SWP9. The chitin binding assay showed that, within the total spore protein, SWP9 and SWP7 can bind to the deproteinated chitin spore coats（DCSCs） of N. bombycis. However, binding of the recombinant protein r SWP7-His to the DCSCs is dependent on the combination of r SWP9–glutathione S-transferase（GST） with the DCSCs. Finally, r SWP9-GST, anti-SWP9, and anti-SWP7 antibodies decreased spore adhesion and infection of the host cell. In conclusion, SWP7 and SWP9 may have important structural capacities and play significant roles in modulating host cell adherence and infection in vitro. A possible major function of SWP9 is as a scaffolding protein that supports other proteins（such as SWP7） that form the integrated spore wall of N. bombycis.
