The Cucurbita genus contains several economically important species in the Cucurbitaceae family. Here, we report high-quality genome sequences of C. maxima and C. moschata and provide evidence supporting an allotetraploidization event in Cucurbita. We are able to partition the genome into two homoeologous subgenomes based on different genetic distances to melon, cucumber, and watermelon in the Benincaseae tribe. We estimate that the two diploid progenitors successively diverged from Benincaseae around 31 and 26 million years ago （Mya）, respectively, and the allotetraploidization happened at some point between 26 Mya and 3 Mya, the estimated date when C. maxima and C. moschata diverged. The subgenomes have largely maintained the chromosome structures of their diploid progenitors. Such long-term karyotype stability after polyploidization has not been commonly observed in plant polyploids. The two subgenomes have retained similar numbers of genes, and neither subgenome is globally dominant in gene expression. Allele-specific expression analysis in the C. maxima ×C. moschata interspecific F1 hybrid and their two parents indicates the predominance of trans-regulatory effects underlying expression divergence of the parents, and detects transgressive gene expression changes in the hybrid correlated with heterosis in important agronomic traits. Our study provides insights into polyploid genome evolution and valuable resources for genetic improvement of cucurbit crops.

Induced pluripotent stem cells(iPSCs)can be personalized and differentiated into neural stem cells(NSCs),thereby effectively providing a source of transplanted cells for spinal cord injury(SCI).To further improve the repair efficiency of SCI,we designed a functional neural network tissue based on TrkC-modified iPSC-derived NSCs and a CBD-NT3-modified linear-ordered collagen scaffold(LOCS).We confirmed that transplantation of this tissue regenerated neurons and synapses,improved the microenvironment of the injured area,enhanced remodeling of the extracellular matrix,and promoted functional recovery of the hind limbs in a rat SCI model with complete *** sequencing and metabolomic analyses also confirmed the repair effect of this tissue from multiple perspectives and revealed its potential mechanism for treating ***,we constructed a functional neural network tissue using human iPSCs-derived NSCs as seed cells based on the interaction of receptors and ligands for the first *** tissue can effectively improve the therapeutic effect of SCI,thus confirming the feasibility of human iPSCs-derived NSCs and LOCS for SCI repair and providing a valuable direction for SCI research.

对于给定的约束,数据库可能是非一致的。为了获得一致性结果,基于一阶逻辑,提出非一致性关系数据管理框架,研究多种合取查询类型对应的连接图及其连接的充分性,分析一致性查询应答的计算复杂度。在查询连接类型是键-键、非键-键或不充分的键-键,且查询对应的连接图是非环的情况下,一致性查询应答的计算在多项式时间内是可解的。针对大量实际的易处理合取查询,给出查询重写算法获得可重写的查询。算法首先判断初始查询是否为可重写,再基于连接图进行递归计算构造一致性识别语句,然后,与初始查询合取产生一个新的一阶重写查询,用于计算一致性结果。对于非环的自连接查询,由于递归重写算法不能剔除非一致性元组,因此,采用初始查询获取了用于剔除违反键约束的非一致性元组的语句。
