In angiosperms,the molecular mechanism controlling polytubey/polyspermy block and fertilization recovery was not unraveled until recently(Zhong et al.,2022),which can be described as fol ows:Five pol en tube-expressed RALF peptide ligands,perceived by the receptor complex composed of three receptors FER/ANJ/HERK1 at the septum,establish the polytubey block at the septum so that only one pollen tube is allowed to emerge from the septum to target the ovule for *** tube rupture releases the two sperm cells and fertilization is completed within 20 min.

Currently, prosthetic hands can only achieve several prespecified and discrete hand motion patterns from popular myoelectric control schemes using electromyography(EMG) signals. To achieve continuous and stable grasping within the discrete motion pattern, this paper proposes a control strategy using a customized, flexible capacitance-based proximity-tactile sensor. This sensor is integrated at the fingertip and measures the distance and force before and after contact with an object. During the pregrasping phase, each fingertip’s position is controlled based on the distance between the fingertip and the object to make all fingertips synchronously approach the object at the same distance. Once contact is established, the sensor turns to output the tactile information, by which the contact force of each fingertip is finely controlled. Finally, the method is introduced into the human-machine interaction control for a myoelectric prosthetic hand. The experimental results demonstrate that continuous and stable grasping could be achieved by the proposed control method within the subject’s discrete EMG motion mode. The subject also obtained tactile feedback through the transcutaneous electrical nerve stimulation after contact.
