Soil-borne pathogens,e.g.,Plasmodiophora brassicae,causes devastating clubroot disease,and existing identified resistance(R)genes has been broken down with the co-evolution of pathogen,threatening the future of cruciferous crops.Thus,there is a dire need to identify new R genes for developing clubroot-resistant crops.Recently,Wang et al.,2023 have reported a new R gene,WeiTsing,that confers complete resistance to Plasmodiophora brassicae,providing an opportunity to deliver broad-spectrum,durable clubroot-resistant crop varieties.

The Chinese People’s Police Day is observed on January 10 every year, corresponding with the country’s emergency call number 110. The establishment of this celebration was approved in 2020 in recognition of the extraordinary work of the country’s public security guardians.“In an age of peace, the police force is a team that sacrifices the most while making the greatest contribution,” said President Xi Jinping at a national conference on public security on May 8, 2019.

The phytohormone abscisic acid(ABA) is an important mediator in the drought response, participating in, among other processes, stomatal movements. In Arabidopsis thaliana, the serine/threonine protein kinase,OST1, regulates this response, but the function of its maize homolog has yet to be established. Here, we isolated ZmOST1 and show that its encoded protein indeed acts to regulate guard cell movement. ZmOST1 was ubiquitously expressed throughout the plant, being highly expressed in guard cells, and inducible both by exogenous ABA and water stress. Transient expression of a ZmOST1-GFP fusion protein, in maize mesophyll protoplasts, indicated its subcellular localization in the cytoplasm and nucleus. A Zmost1 loss-of-function mutant exhibited reduced sensitivity to ABA-activated slow anion channels in maize guard cells, and reduced drought tolerance. Constitutive expression of ZmOST1, in an A. thaliana ost1-1 mutant rescued the phenotype with respect both to the sensitivity of guard cell slow anion currents to ABA treatment and stomatal closure. Our findings indicate a positive regulatory role for ZmOST1 in guard cell ABA signaling and drought response in maize plants.

This paper presents a novel movement planning algorithm for a guard robot in an indoor environment, imitating the job of human security. A movement planner is employed by the guard robot to continuously observe a certain person. This problem can be distinguished from the person following problem which continuously follows the object. Instead, the movement planner aims to reduce the movement and the energy while keeping the target person under its visibility. The proposed algorithm exploits the topological features of the environment to obtain a set of viewpoint candidates, and it is then optimized by a cost-based set covering problem. Both the robot and the target person are modeled using geodesic motion model which considers the environment shape. Subsequently, a particle model-based planner is employed, considering the chance constraints over the robot visibility, to choose an optimal action for the robot. Simulation results using 3D simulator and experiments on a real environment are provided to show the feasibility and effectiveness of our algorithm.

On January 22,2021,a 34-year-old male,who served as a security guard at the isolation point in Shenzhen,tested positive for coronavirus disease 2019(COVID-19)during the every-three-day routine test.After the nasopharyngeal swab was further confirmed as positive for COVID-19 by Shenzhen CDC,the patient was transferred to the Third People’s Hospital of Shenzhen and was diagnosed as a COVID-19 asymptomatic infection.On January 25,2021,Shenzhen CDC identified the 20H/501.Y.V2(B.1.351)variant,which was a variant of COVID-19 virus first emerging in the South Africa.
