Plants are often subjected to DNA damage due to a range of environmental and internal factors in the natural world. Among these factors, DNA double strand breaks（DSBs）have the most serious consequences to plants. If these DSBs are repaired improperly, which may result in genome instability, gene mutations, and even cell death. On one hand, plants have evolved a powerful and well-organized damage repair mechanism to ensure overall survival and normal reproduction. On the other hand, based on the fault-tolerance and mutagenicity of the repair process, a series of techniques such as T-DNA insertion, gene editing, and physical mutagenesis have been widely used for variety improvement in plants and animals. Compared with mammals, reports on DSBs repair pathways and their molecular mechanisms in plants are limited. In this paper, we review the responses of plants to DSBs damage and the main repair mechanisms, and we also focus on the recent advances in alternative end joining（Alt-EJ）, whose mechanism has not yet been fully revealed. In addition, we discuss the characteristics and multi-pathway options of DSBs repair in plants induced by heavy ion beams irradiation, and the progress of gene editing technology based on different DSBs repair pathways. This study aims to provide reference for understanding the molecular mechanism of plant DSBs damage response and developing efficient biological breeding technology. [ABSTRACT FROM AUTHOR]

[Objective] The present paper aimed to analyze the diversity of bacterial communities in the rhizosphere soil of adzuki bean varieties with different resistance to soybean cyst nematode ( SCN) race 3 and explore the correlation between the composition of rhizosphere bacterial communities and variety resistance. [ Method] In July 2021, the 16S rDNA genome of bacteria in the rhizosphere soil of four different resistant adzuki bean varieties under the stress of SCN race 3 was sequenced by Illumina Miseq high-throughput sequencing technology from the rhizosphere soil of four different resistant adzuki bean varieties in Heihe city, Heilongjiang province, to analyze the changes of bacterial community structure. [ Result] A total of 1959 OTU s were obtained from 4 soil samples, and 30 phyla, 85 classes, 192 orders, 296 families, 481 genera and 893 species of bacteria were identified, among which Actinobacteriota, Proteobacteria, Acidobacteriota, Chloroflexi and Gemmatimonadota were the dominant phyla, Sphingomonas, norankJ __ norank_o __ Gaiellales, norankJ __ norank_o __ Acidobacteriales, Gemmatimonas, Blastococcus were the dominant genus. The average relative abundance of Actinobacteriota, Proteobacteria and Gemmatimonadota in the rhizosphere soil of susceptible varieties was lower than that of resistant varieties. The relative abundance of Gemmatimonas and Sphingomonas, which were related to disease resistance, was high in the rhizosphere soil samples of resistant variety Liaohong 1 and immunevariety Jihong 9218. [ Conclusion] The bacterial community structure in the rhizosphere soil of different resistant adzuki beans changed under the stress of SCN race 3, and the relative abundance of antagonistic bacterial populations in the rhizosphere soil of resistant varieties was much higher, which indicated that the bacterial community structure in the rhizosphere soil may be correlated with the resistance of adzuki beans to SCN.

BACKGROUND: At present, there is evidence that domestic porous tantalum has good biocompatibility and osteogenic properties, but the specific osteogenic mechanism and its effect on osteogenic factors are still unclear. OBJECTIVE: To observe the effects of domestic porous tantalum materials on the expression of collagen type I, tissue transglutaminase-2 and calcium-binding protein A4 in MG63 cells. METHODS: MG63 cells in logarithmic growth phase were inoculated onto 24-well plates and cultured in three groups: in blank group, conventional medium was added; in tantalum extract group, porous tantalum material extract was added; and in tantalum scaffold group, porous tantalum material and conventional medium were added. On 1, 3, 5, 7 and 9 days of culture, the cell proliferation of each group was detected by cell counting kit-8 method. On 5 days of culture, the levels of collagen type I, tissue transglutaminase-2 and calcium-binding protein A4 secreted by MG63 cells in each group were detected by ELISA. Western blot assay was used to detect the expression of three proteins in each group. RESULTS AND CONCLUSION: (1) With the prolongation of culture time, the number of cells in each group increased gradually. There was no difference in cell proliferation among the three groups at different time points (P > 0.05). (2) The secretory levels of collagen type I and tissue transglutaminase-2 in the tantalum scaffold group were significantly higher than those in the blank group and tantalum extract group (P < 0.05), while the secretion of collagen type I and tissue transglutaminase-2 in the tantalum extract group was significantly higher than that in the blank group (P < 0.05). The secretion of calcium-binding protein A4 in the tantalum scaffold group was significantly lower than that in the other two groups (P < 0.05). (3) The expression of collagen type I and tissue transglutaminase-2 protein in the tantalum scaffold group was significantly higher than that in the blank group and tantalum extract group (P < 0.05), while the expression of collagen type I and tissue transglutaminase-2 protein in the tantalum extract group was significantly higher than that in the blank group (P < 0.05). The expression of calcium-binding protein A4 in the tantalum scaffold group was significantly lower than that in the blank group and tantalum extract group (P < 0.05). To conclude, domestic porous tantalum materials could promote the secretion of collagen type I and tissue transglutaminase-2 by MG63 cells, and inhibit the secretion of calcium-binding protein A4.
