This application relates to the field of maize technology, specifically to the ZmPAR1 gene and its applications. A gene encoding a nucleoside kinase was discovered in the maize genome. This nucleoside kinase was obtained through in vitro recombinant expression of the encoded gene. Testing revealed that this nucleoside kinase exhibits binding activity to various nucleoside substrates and can catalyze the synthesis of monophosphate nucleotides from nucleosides. This gene influences maize plant height, leaf angle, ear height, leaf length, and leaf width. Knocking down or overexpressing this gene can yield new maize materials, providing technical support for the breeding of new maize materials and the construction of germplasm resources.

The invention discloses a rice leaf phenotype parameter extraction method. According to the method, firstly, collected rice three-dimensional point cloud data are preprocessed, then skeletonization processing is carried out, and a rice point cloud skeleton maintaining a topological structure is obtained; on the basis, identifying a blade tip point and a root node, and converting the skeleton into a graph structure; the method comprises the following steps of: endowing growth cost weights to edges of a graph, and extracting a plurality of blade central axes by taking a blade tip point and a root node as path end points; based on the central axis of a single blade, a corresponding single-blade point cloud can be segmented from an original point cloud, and then multi-dimensional phenotypic parameters such as the blade length, the blade width and the blade included angle are calculated. According to the method, high-throughput and high-precision leaf phenotype extraction under a complex plant structure is realized, and the crop breeding efficiency and the intelligent level of agricultural management are effectively improved.

Embodiments of the present disclosure provide a plant phenotype parameter extraction method, device and equipment and a storage medium, relating to the technical field of data processing. The method obtains plant preliminary voxel data from plant point cloud data, and performs voxel segmentation on the plant preliminary voxel data to obtain leaf point cloud data of the plant, thereby performing parameter extraction on different plant parts, improving data processing efficiency and result accuracy. Next, principal component analysis is performed on the plant point cloud data to obtain plant height and plant width, and similarity clustering is performed on the leaf point cloud data to obtain the number of leaves of the plant. Then, principal component analysis is performed on the leaf point cloud data to obtain leaf length and leaf width, and surface reconstruction is performed on the leaf point cloud data to obtain leaf area. Finally, rich phenotype parameters are obtained from the point cloud data, including plant height, plant width, number of leaves, leaf length, leaf width and leaf area.

The invention belongs to the technical field of molecular genetics, and particularly relates to an application of a ZmNAL4 gene or an encoded protein thereof in regulation and control of leaf morphology and plant height of a plant. The analysis of the expression mode of the flavin monooxygenase gene ZmNAL4 in amphiphilic and transgenic plants shows that the leaf width of an overexpression strain is increased by 13.2% and the plant height is increased by 14.8% compared with that of a gene editing strain, and the leaf area and the plant height of an arabidopsis overexpression plant are obviously higher than those of a wild plant, so that the ZmNAL4 has a positive regulation effect on the leaf width; interaction protein analysis identifies that density-tolerant response factors Zmfdx1 and Zmfdx2 and leaf included angle candidate genes ZmPDHE1 and ZmNAL4 interact with each other; plant endogenous hormone analysis shows that the ZmNAL4 regulates and controls the leaf form and the plant height by influencing an auxin signal and a brassinolide path; gene resources and theoretical basis are provided for research on density-tolerant plant types with reasonable leaf widths of corn, and the method has important significance on density-tolerant high-yield breeding.

The application discloses a tea tree CsGAMYB gene and application thereof in regulation of leaf growth and development, wherein the CDS sequence is shown as SEQ ID NO. 1. A gene interfering with CsGAMYB gene expression is a precursor sequence of a tea tree miR159b gene. In an Arabidopsis thaliana miR159b overexpression strain, leaf length, leaf width, leaf area and petiole length are significantly increased; in an Arabidopsis thaliana CsGAMYB overexpression strain, leaf length, leaf width, leaf area and petiole length are significantly reduced; through microscope observation, lower epidermal cells of the leaf are obviously less than WT in the miR159b overexpression plant, and obviously more than WT in the CsGAMYB overexpression plant, overexpression of CsGAMYB in the plant inhibits cell growth, leading to reduction of leaf thickness, area, length and width, and overexpression of miR159b can restore development of the plant leaf.
