The invention discloses an endangered plant phoebe hainanensis identification and systematic monitoring method based on multi-source data fusion, and belongs to the technical field of endangered plant protection. According to the method, a potential distribution area is delineated through a species distribution model, individual accurate identification and filing are achieved through a multi-branch feature fusion model, multi-scale growth and microenvironment data are collected through Internet of Things nodes, and finally a'discovery-identification-monitoring-protection 'whole-process closed loop is formed through a unified data management platform. According to the method, phenological feature extraction, transfer learning modeling, man-machine collaborative verification and low-power-consumption Internet of Things monitoring technologies are adopted, and the problems that a traditional method is low in efficiency, insufficient in recognition precision and fragmented in monitoring are solved. According to the method, efficient discovery, accurate identification and long-term dynamic monitoring of the wild population of the phoebe hainanensis are achieved, scientific support is provided for protection decision making, and the method is convenient to operate and high in practicability and has protection value and application prospects.

The invention belongs to the technical field of plant genetic engineering, and discloses a machilus nanmu TPS synthetase gene MnTPS4 and application thereof. The Machilus davidii TPS synthetase gene MnTPS4 provided by the invention is a key gene for synthesis of (+)-Camphene / Borneol / Geraniol in plant genetic engineering, synthesis of (+)-Camphene / Borneol / Geraniol can be effectively regulated and controlled, expression protein of the Machilus davidii TPS synthetase gene MnTPS4 is applied to synthesis and preparation of (+)-Camphene / Borneol / Geraniol, and the Machilus davidii TPS synthetase gene MnTPS4 has important application value.

According to the machilus rubescens TPS synthetase gene MnTPS8 and the application thereof, the gene is obtained from machilus rubescens through cloning for the first time and has beta-Eudesmol and Geraniol synthesis functions, and a new gene resource is provided for functional diversity and evolution analysis of a terpene synthetase gene family. Recombinant protein coded by the MnTPS8 gene has a unique dual-catalysis function, GPP can be catalyzed to generate Geraniol, FPP can be catalyzed to generate beta-Eudesmol, and compared with a single-function gene, the synchronous production process of two high-value terpenoids is greatly simplified, and the production cost is reduced. When the gene is used for heterologous expression or transgenic plant cultivation, synchronous large-scale production of beta-Eudesmol and Geraniol can be realized, the yield limitation of natural extraction is broken through, and the gene has remarkable economic value and industrial application prospect.

The utility model relates to the field of cultivation devices, in particular to a cultivation device with an adjusting function for phoebe sheareri breeding, which comprises a cultivation box and an adjusting sealing assembly. The outer end of the cultivation box is provided with an adjusting sealing assembly used for adaptive adjustment according to the seedling raising mode. The adjusting sealing assembly comprises a fixed plate, a transparent sealing frame, a movable plate, a thermometer, a heating pipe and a storage plate. By adopting the transparent sealing frame, full irradiation of sunlight can be guaranteed in the sealed cultivation process, photosynthesis of phoebe sheareri seedlings is promoted, good growth conditions are provided for breeding of phoebe sheareri, meanwhile, ultraviolet rays in the sunlight have a sterilization effect, breeding of germs can be reduced, the risk that the phoebe sheareri seedlings suffer from diseases is reduced, and the phoebe sheareri seedlings are protected from being damaged. Secondly, the transparent sealing frame can be disassembled and assembled according to breeding requirements, switching between open-air cultivation and sealed cultivation is achieved, damage to seedling root systems is reduced, the device can better adapt to different growth stages of phoebe sheareri, and the breeding survival rate of phoebe sheareri is increased.
