Regulation of lignin biosynthesis by GhCAD37 affects fiber quality and anther vitality in upland cotton.

Cotton stands as a pillar in the textile industry due to its superior natural fibers. Lignin, a complex polymer synthesized from phenylalanine and deposited in mature cotton fibers, is believed to be essential for fiber quality, although the precise effects remain largely unclear. In this study, we characterized two ubiquitously expressed cinnamyl alcohol dehydrogenases (CAD), GhCAD37A and GhCAD37D (GhCAD37A/D), in Gossypium hirsutum.

18F-FDG PET/CT in a Patient With Epididymo-Testicular Malacoplakia.

A 56-year-old man presented with a 2-month history of a mass in the right epididymo-testicular region, which exhibited heterogeneous high avidity for 18F-FDG on PET/CT. Malignant tumor was highly suspected, leading to subsequent right orchiectomy and epididymectomy. Histopathological examination revealed the presence of characteristic Michaelis-Gutmann bodies within von Hansemann macrophages, confirming the diagnosis of malacoplakia.

Identification and Characterization of Cinnamyl Alcohol Dehydrogenase Encoding Genes Involved in Lignin Biosynthesis and Resistance to in Upland Cotton ( L.).

Verticillium wilt, caused by the soil-borne fungus , is one of the most devastating diseases in cotton ( spp.). Lignin in the cell wall forms a physical barrier to inhibit pathogen invasion, and defense-induced lignification reinforces secondary cell wall to prevent pathogens from further spreading.

Moiré alignment algorithm for an aberration-corrected holographic grating exposure system and error analysis.

To meet the required manufacturing accuracy of high-quality aberration-corrected holographic gratings, we propose a moiré alignment algorithm for the exposure system of holographic gratings. A model holographic grating exposure system is built with multiple degrees of freedom based on optical path function theory. The whole process algorithm is then derived, including the fourth-order orthogonal polynomial of the holographic gratings, fitted aberration coefficients, and an optimized Levenberg-Marquardt algorithm for the exposure system's recording parameters.

[Study on the Effects and Compensation Effect of Recording Parameters Error on Imaging Performance of Holographic Grating in On-Line Spectral Diagnose].

To making the high resolution grating, a numerical calculation was used to analyze the effect of recording parameters on groove density, focal curve and imaging performance of the grating and their compensation. Based on Fermat' s principle, light path function and aberration, the effect on imaging performance of the grating was analyzed. In the case of fixed using parameters, the error of the recording angle has a greater influence on imaging performance, therefore the gain of the weight of recording angle can improve the accuracy of the recording angle values in the optimization; recording distance has little influence on imaging performance; the relative errors of recording parameters cause the change of imaging performance of the grating; the results indicate that recording parameter errors can be compensated by adjusting its corresponding parameter.
