The MdSINA1-MdWOX8-MdHY5 module links strigolactone and gibberellin signals via interaction with MdSMXL8 and MdRGL3a in the regulation of anthocyanin biosynthesis in apple.

The strigolactone (SL) and gibberellin (GA) signals jointly regulate various aspects of plant growth and development. However, the molecular regulatory network underlying the crosstalk between the SL and GA signaling pathways remains poorly understood. In this study, we found that ELONGATED HYPOCOTYL 5 (MdHY5) serves as an integrator of SL and GA signals in apple (Malus × domestica), and the WUSCHEL-related homeobox (WOX) transcription factor MdWOX8 enhances anthocyanin biosynthesis by directly activating MdHY5 expression.

Anisotropic phase stiffness in infinite-layer nickelates superconductors.

In unconventional superconductors such as cuprates and iron pnictides and chalcogenides, phase stiffness-a measure of the energy cost associated with superconducting phase variations-governs the formation of superconductivity. Here we demonstrate a vector current technique enabling in-situ angle-resolved transport measurements to reveal anisotropic phase stiffness in infinite-layer nickelate superconductors. Pronounced anisotropy of in-plane resistance manifests itself in both normal and superconducting transition states, indicating crystal symmetry breaking.

A Critical Review of the CRISPR-Cas Technology in the Detection of SARS-CoV-2 Variants.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is still going on, and as the epidemic situation continues, the genome of SARS-CoV-2 is also mutating and evolving, resulting in more and more SARS-CoV-2 mutant strains, which have brought serious pressure on the prevention and control of COVID-19. Given that the COVID-19 is still spreading, it is extremely important to rapidly identify SARS-CoV-2 variants by nucleic acid assays. Thus, developing highly sensitive and specific assays that are suitable for field testing, high-throughput, and automation, as well as other diagnostic applications for SARS-CoV-2 variants, is urgently needed.
