  • Publication number: 20230175000
    Abstract: The present invention relates to a maize gene ZmRAVL1 and a functional site and use thereof. The present invention locates the functional site for controlling the leaf angle phenotype to 240 bp by fine-mapping, and the insertion and deletion of this region lead to different leaf angle phenotypes. The present invention demonstrates that an inbred line improved with an excellent natural variation from the teosinte can increase maize yield under dense planting and broaden the source of elite alleles available in plant breeding. The present invention demonstrates that a reduced ZmRAVL1 expression by a genetic engineering technique (RNAi) has an influence on plant architectures, such as a reduced leaf angle, and thus it provides excellent genetic resources for genetic engineering breeding.

  • Publication number: 20230100014
    Abstract: Techniques relating to monitoring map consistency are described. In an example, a monitoring component associated with a vehicle can receive sensor data associated with an environment in which the vehicle is positioned. The monitoring component can generate, based at least in part on the sensor data, an estimated map of the environment, wherein the estimated map is encoded with policy information for driving within the environment. The monitoring component can then compare first information associated with a stored map of the environment with second information associated with the estimated map to determine whether the estimated map and the stored map are consistent. Component(s) associated with the vehicle can then control the object based at least in part on results of the comparing.
