CDPK5 and CDPK13 play key roles in acclimation to low oxygen through the control of RBOH-mediated ROS production in rice.

CALCIUM-DEPENDENT PROTEIN KINASE (CDPK) stimulates reactive oxygen species (ROS)-dependent signaling by activating RESPIRATORY BURST OXIDASE HOMOLOG (RBOH). The lysigenous aerenchyma is a gas space created by cortical cell death that facilitates oxygen diffusion from the shoot to the root tips. Previously, we showed that RBOHH is indispensable for the induction of aerenchyma formation in rice (Oryza sativa) roots under low-oxygen conditions.

NADPH oxidase-mediated sulfenylation of cysteine derivatives regulates plant immunity.

Reactive oxygen species (ROS) are rapidly generated during plant immune responses by respiratory burst oxidase homolog (RBOH), which is a plasma membrane-localized NADPH oxidase. Although regulatory mechanisms of RBOH activity have been well documented, the ROS-mediated downstream signaling is unclear. We here demonstrated that ROS sensor proteins play a central role in ROS signaling via oxidative post-translational modification of cysteine residues, sulfenylation.

Noise-Robust Pulse Wave Estimation from Near-Infrared Face Video Images Using the Wiener Estimation Method.

In this paper, we propose a noise-robust pulse wave estimation method from near-infrared face video images. Pulse wave estimation in a near-infrared environment is expected to be applied to non-contact monitoring in dark areas. The conventional method cannot consider noise when performing estimation.

12th Japan-US Seminar in Plant Pathology Meeting Report.

The 12th iteration of the Japan-US Seminar in Plant Pathology was held in Ithaca, New York at Cornell University in the fall of 2022. Presentations covered a range of topics under the theme "Remodeling of the Plant-Microbe Environment During Disease, Defense, and Mutualism," and the meeting included a panel discussion of best practices in science communication. This report presents highlights of the meeting, from the perspective of early career participants of the seminar.
