This invention discloses PtoNAC028 The gene is used to regulate the ratio of pectin monomers in poplar trees. The coding region of this gene has the nucleotide sequence shown in SEQ ID NO:1. This is achieved through overexpression or silencing of the gene in poplar trees. PtoNAC028 Genes capable of increasing or decreasing the proportion of lignin monomers in poplar provide key genes for the genetic improvement of poplar processing traits. This invention also discloses a method for cultivating poplars with a high lignin monomer ratio, through overexpression of [gene name missing] in poplar trees. PtoNAC028 The gene can significantly increase the proportion of lignin monomers in poplar trees, achieving targeted regulation of monomeric lignin metabolism, which helps to rapidly cultivate new poplar varieties with excellent wood properties and fast growth.

The application discloses a kind of based on three-dimensional point cloud image's Pinus massoniana partial phenotypic parameter automatic measurement method. Three-dimensional point cloud image of Pinus massoniana plant under different viewing angles is collected;Pretreatment obtains the three-dimensional point cloud of Pinus massoniana plant;Registration is carried out to obtain fused point cloud;Extract the minimum spanning tree and the skeleton point of main stem, and then obtain the main stem point cloud and leaf point cloud;According to the minimum spanning tree, main stem point cloud and leaf point cloud processing obtain main stem length, Pinus massoniana ground diameter, average leaf length and leaf number.The method of the application can automatically identify Pinus massoniana plant in three-dimensional point cloud image, and complete the strategy of main diameter length, ground diameter, average leaf length, leaf length, improve the detection efficiency, realize high-precision, high-efficiency crop phenotypic data acquisition, achieve fast, low-cost crop phenotypic parameter accurate and nondestructive testing.

The application discloses a culture method for propagating Brachythecium populeum, and belongs to the technical field of Brachythecium populeum tissue culture. The application uses sporangium as an explant to propagate Brachythecium populeum, and quickly obtains Brachythecium populeum spores with a high germination rate, establishes a regeneration system of Brachythecium populeum, lays a foundation for large-scale propagation of Brachythecium populeum, shortens the propagation cycle of Brachythecium populeum, and better maintains excellent properties. The application first establishes a method for culturing Brachythecium populeum by using spores, fills the blank of the prior art, and provides a technical basis for propagation, seed preservation, preparation of protoplasts, recombination experiments and gametophyte culture of Brachythecium populeum.
