The application discloses a method for detecting chicken breast with wood and white line symbiotic muscle defects by hyperspectral imaging, and comprises the following steps: acquiring wood meat samples and white line meat samples with different grade gradients; acquiring hyperspectral images of the samples; extracting image texture features; preprocessing spectral data; selecting characteristic wavelengths for the spectrum; measuring the physicochemical quality of the samples; taking the image texture features and the spectral data under the selected characteristic wavelengths as inputs, and taking quality index values as outputs, to establish a CNN model; collecting hyperspectral images of chicken breast with wood and white line symbiotic muscle defects, inputting the image texture features and the spectral information of each pixel point in the multispectral image under the characteristic wavelength points into the optimized CNN model, obtaining comprehensive quality index values of each pixel point, respectively assigning colors to each pixel point, and forming a classified visual image; and the model detection and the visual image can accurately analyze and represent the symbiotic state of the white line and the wood tissue.

The invention provides an integrated system and method for fabricating, regenerating, and maintaining synthetic living wood tissue constructs. The platform utilizes a formulation subsystem that prepares plant-derived precursor cells, lineage-directing Exomix signaling vesicles, and a supportive cellulose-based hydrogel into a printable bio-ink. An additive biofabrication subsystem generates structured constructs containing organized cambial, xylem, and phloem domains, microfluidic vascular channels, and embedded niche reservoirs. A maintenance and repair subsystem preserves tissue viability, delivers targeted regeneration cues, and supports long-term integration with damaged or aging wood substrates. Environmental control modules regulate electrical, mechanical, thermal, and biochemical parameters to guide differentiation and maturation. The invention enables sustainable production of regenerative wood materials with enhanced strength, decay resistance, and customizable properties, addressing limitations of natural wood through controlled biomanufacturing and restoration workflows.

The present application relates to a method and application for changing the fiber cell wall thickness and lignin content of poplar wood tissue, and belongs to the technical field of plant molecular breeding; the steps are as follows: S1: cloning of the genomic sequence and coding sequence of PtoMYB10; S2: screening of PtoMYB10 target site knockout and vector construction; S3: creation of PtoMYB10 knockout mutants. The method and application for changing the fiber cell wall thickness and lignin content of poplar wood tissue of the present application, by knocking out the PtoMYB10 gene of poplar, the mutant plants show higher growth vigor, compared with the wild type, the plant height and ground diameter are not inhibited by growth; the mutant plants show significantly reduced xylem fiber cell wall thickness; the mutant plants do not show significant changes in vessel cell wall thickness, the vessels maintain normal morphology without collapse; histological staining shows that the lignin content in the xylem of the mutant plants is reduced; the present application provides a genetic resource for molecular genetic improvement of forest trees oriented towards wood biomass development and utilization.
