Summary: The study demonstrates that CCPO proteins fold in a stepwise sequential pathway, influenced by the spatial distance between CC modules in the primary sequence and subsequent folding intermediates. This design approach allows the utilization of identical CC modules for the design of CCPO tetrahedron.

Summary: Plant hormone brassinosteroids (BRs) play crucial roles in plant immunity by regulating the expression of callose synthase gene GLUCAN SYNTHASE-LIKE 8 (GSL8) and promoting callose accumulation, which enhances the resistance to pathogen infection. The molecular mechanism and key components of BR-induced pathogen resistance remain to be fully elucidated.

Summary: The ubiquitin-proteasome system plays a crucial role in hormone-mediated developmental and stress responses in plants. This study uncovers the sequential ubiquitin ligases that regulate NPR1 and EIN3, and reveals their relay to proteasome-associated HECT-type ligases, controlling hormone-induced developmental and stress-responsive transcriptional programs.

Summary: Calcium (Ca2+) signaling is a crucial universal information code in plants, which is decoded into specific adaptive responses by different Ca2+ sensing proteins. Although the molecular details of these processes are still largely unknown, studying the kinetics of different proteins and their interactions with targets can provide insights into Ca2+ decoding and target binding mechanisms controlled by Ca2+ in plants.

Summary: In Arabidopsis thaliana, local wounding and herbivore feeding trigger Ca2+ waves that are dependent on the activity of glutamate receptor-like channels (GLRs). GLRs are also required for the synthesis of jasmonic acid (JA) and the subsequent signaling response for plant acclimation. The mechanism of GLR activation is still unclear.

Summary: The study characterized the properties of AtKRP125b, a kinesin-5 protein in Arabidopsis thaliana, demonstrating its role in spindle formation, microtubule cross-linking, and sliding; in addition to its nuclear localization and processive movement, the promoter activity of AtKRP125b was found to be tissue-specific, with expression in vascular tissues but not in meristematic tissues.

Summary: This study compared the photosynthesis properties of duckweed and Arabidopsis, and found that duckweed had more effective light energy transfer and more stable photosynthesis parameters, especially under high light intensities. This may be associated with molecular differences in photosynthesis proteins, potentially leading to improved photosynthesis and growth efficiencies.

Summary: Lipid anchors are common post-translational modifications for proteins involved in signaling and vesicular transport in eukaryotic cells. The mechanism of REP-Rab binding in plants is different from that in animals or yeast, and the role of REP in Rab prenylation is also distinct in plants, which is significant for plant research.
