BoMYBL2b, an R3-MYB transcription factor, inhibits anthocyanin accumulation via directly repressing BoDFR1 gene transcription in kale.

Kale is a globally popular edible and ornamental plant with colorful inner leaves. Anthocyanin is one of the most major pigments for kale. However, the underlying regulatory mechanism for the accumulation of anthocyanin in kale has not been well understood to date.

The Wsp chemosensory system modulates c-di-GMP-dependent biofilm formation by integrating DSF quorum sensing through the WspR-RpfG complex in Lysobacter.

The ubiquitous Wsp (wrinkly spreader phenotype) chemosensory system and DSF (diffusible signal factor) quorum sensing are two important chemically associated signaling systems that mediate bacterial communications between the host and environment. Although these two systems individually control biofilm formation in pathogenic bacteria via the ubiquitous second messenger c-di-GMP, their crosstalk mechanisms remain elusive. Here we present a scenario from the plant-beneficial and antifungal bacterium Lysobacter enzymogenes OH11, where biofilm formation favors the colonization of this bacterium in fungal hyphae.

Strongly-adhesive easily-detachable carboxymethyl cellulose aerogel for noncompressible hemorrhage control.

Hemostats that can strongly adhere to wound tissue and are easy to remove when stopping bleeding are favored for the control of noncompressible hemorrhage. Here, we prepared a citric acid (CA)-crosslinked and N-hydroxysuccinimide (NHS) ester-activated carboxymethyl cellulose (CMC-NHS) aerogel for noncompressible hemostasis. CA was used to crosslink CMC to form a strengthened structure.

Dynamic Analysis and Optimal Control of Rumor Spreading Model with Recurrence and Individual Behaviors in Heterogeneous Networks.

This paper is devoted to investigating the impact of the recurrence of rumors and individual behaviors and control strategies related to rumor spreading in online social networks. To do this, a novel susceptible-hesitating-infected-latent-recovered (SHILR) rumor propagation model in heterogeneous networks is presented. Firstly, based on the relevant mean-field equations of the model, the threshold value is examined to demonstrate the existence and stability of rumor-free/spreading equilibrium with the help of the algebraic method.

Interfacial Chemical Effects of Amorphous Zinc Oxide/Graphene.

Research on the preparation and performance of graphene composite materials has become a hotspot due to the excellent electrical and mechanical properties of graphene. Among such composite materials, zinc oxide/graphene (ZnO/graphene) composite films are an active research topic. Therefore, in this study, we used the vacuum thermal evaporation technique at different evaporation voltages to fabricate an amorphous ZnO/graphene composite film on a flexible polyethylene terephthalate (PET).
