Abstract

Abstract [Objective] Callose is a beta-1, 3-bonded glucan that forms a wall structure, which occurs only in certain tissues. When degrading prematurely or delayed, it may lead to pollen abortion. Examining the dynamics of callose deposition is important for understanding the mechanism of male sterility and its application. [Methods] The fertile line ‘Ningqi No.1’ and sterile line ‘Ningqi No.5’ of Lycium barbarum L. were studied using semi-thin section technique, and callose was labeled with aniline blue and periodic acid- Schiff stain (PAS). The dynamic characteristics of callose in fertile and sterile anthers of L. barbarum at different developmental stages were compared under optical microscope, and the influence of callose on anther abortion of sterile line was analyzed. [Results] In the microspore mother stage, the extracellular deposits of fertile and sterile anthers formed an uneven thick callose wall, and the fluorescence reaction showed that the callose wall gradually was thickened after meiosis forming a tetrad. With the further development of anthers, the extracellular callose wall in fertile anthers gradually disintegrated and disappeared, releasing 4 microspores. However, in sterile anthers, the callose wall outside the tetrad was thickened continuously, and there was no sign of degradation. Until flowering, the small spores in the anther chamber still existed in the state of tetrad, and the callose wall was still wrapped around the deformed and disintegrated tetrad. [Conclusion] Abnormal callose degradation was the structural cause of pollen abortion in Ningxia wolfberry. This study further analyzed the reason why the callose wall of the sterile line tetrad did not degrade, and provides a theoretical basis for analyzing the male sterility mechanism of L. barbarum L..

Abstract

In this study, the functional genomic characteristics of Lactiplantibilus plantarum ST were analyzed. Comparative genomic analysis was performed on the whole genome sequences of L. plantarum ST and the type strain L. plantarum ATCC 14197T as well as those of 152 L. plantarum strains published in the NCBI GenBank. A phylogenetic tree was constructed based on 1 262 core genes of these 154 L. plantarum strains, and the genetic distance between ST and the intestinal isolate BCC9546 was found to be the closest. The isolates originated from milk and meat products were concentrated in the upper part and the lower part of the second branch, respectively, and they were different due to different sources and could be aggregated. Meanwhile, Drosophila isolates showed a significant aggregation trend. Functional annotation analysis suggested that the ST genome contained genes related to the phosphotransferase system (PTS) as a major carbohydrate transport system. Genes related to the immune regulatory pathway were also annotated. There were many genes related to the hydrolysis or rearrangement of glycosidic bonds, but no virulence factors or antibiotics resistance genes found in ST. Compared with the other L. plantarum isolates, ST carried the unique functional gene ecfT related to energy transport function. In addition, ST had functional genes involved in the synthesis of the quorum-sensing signaling molecule AI-2, glutathione, and adhesion molecules. The results of API 50 CHL carbohydrate metabolism showed that L. plantarum ST could utilize a wide range of carbon sources and metabolize 29 carbon sources including monosaccharides, glycosides, disaccharides and polysaccharides. This study provides a genetic basis for the development and utilization of L. plantarum ST as a safe probiotic strain.
