1hSSB1 regulates both the stability and the transcriptional activity of p53显示文摘肿瘤 suppressor p53 为涉及对多样的 genotoxic 应力的反应的几个细胞的过程是必要的,包括房间周期拘捕, DNA 修理, apoptosis 和老朽。p53 的规定的研究主要集中了于它的稳定性和 transactivation;然而,为 p53 的新规章的分子经常也被识别了。这里,我们报导那人的 ssDNA 绑定蛋白质 SSB1 (hSSB1 ) ,新奇 DNA 联系损坏的蛋白质,能与 p53 交往并且保护 p53 免受调停 ubiquitin 的降级的伤害。而且, hSSB1 也与 acetyltransferase p300 联系并且被在 lysine382 影响 p53 的 acetylation 为 p53 目标基因 p21 的有效 transcriptional 激活要求。机能上地, G2/M 检查点的 hSSB1 击倒导致废除部分依赖于 p53 或 p300。一起,我们的结果显示那 hSSB1 可以调整 DNA 损坏检查点由断然 modulating p53 和它的下游的目标 p21。Shuangbing Xu Yuanzhong Wu Qiong Chen Jingying Cao Kaishun Hu Jianjun Tang Yi Sang Fenju Lai Li Wang Ruhua Zhang Sheng-Ping Li Yi-Xin Zeng Yuxin Yina Tiebang Kang 2013Cell Research2013,23,3:7
2Genetic mechanism of heterosis for rice milling and appearance quality in an elite rice hybrid显示文摘Development of hybrid rice with high yield and grain quality is a goal of rice breeding.To investigate the genetic mechanism of heterosis for rice milling and appearance quality in indica/xian rice,QTL mapping was conducted using 1061 recombinant inbred lines(RILs)derived from a cross of the xian rice cultivars Quan 9311B(Q9311B)and Wu-shan-si-miao(WSSM),and a backcross F_(1)(BC_(1)F_(1)) population developed by crossing the RILs with Quan 9311A(Q9311A),combined with phenotyping in two environments.The F_(1) hybrid(Q9311A×WSSM)showed various degrees of heterosis for milling and appearance quality.A total of 142 main-effect QTL(M-QTL)and 407 pairs of epistatic QTL(E-QTL)were identified for five milling and appearance quality traits and grain yield per plant(GYP)in the RIL,BC_(1)F_(1) and mid-parental heterosis(H_(MP)) populations.Differential detection of QTL in three populations revealed that most additive loci detected in the RILs did not show heterotic effects,but some of them did contribute to BC_(1)F_(1) trait performance.Unlike heterosis of GYP,single-locus overdominance and epistasis were the main contributors to heterosis for milling and appearance quality.Epistasis contributed more to the heterosis for milling quality than to that for appearance quality.Three(four)QTL regions harboring opposite(consistent)directions of favorable allele effects for GYP and grain quality were identified,indicating the presence of partial genetic overlaps between GYP and grain quality.Three strategies are proposed to develop hybrid rice with high yield and good grain quality:1)pyramiding favorable alleles with consistent directions of gene effects for GYP and grain quality at the M-QTL on different chromosomes;2)introgressing favorable alleles for GYP and grain quality into the parents and then pyramiding and fixing these additive effects in hybrids;and 3)pyramiding overdominant and dominant loci and minimizing or eliminating underdominant loci from the parents.Hui You Sundus Zafar Fan Zhang Shuangbing Zhu Kai Chen Congcong Shen Xiuqin Zhao Wenzhong Zhang Jianlong Xu 2022The Crop Journal2022,10,6:1
3A novel Effective Panicle Number per Plant 4 haplotype enhances grain yield by coordinating panicle number and grain number in rice显示文摘Increasing effective panicle number per plant(EPN)is one approach to increase yield potential in rice.However,molecular mechanisms underlying EPN remain unclear.In this study,we integrated mapbased cloning and genome-wide association analysis to identify the EPN4 gene,which is allelic to NARROW LEAF1(NAL1).Overexpression lines containing the Teqing allele(TQ)of EPN4 had significantly increased EPN.NIL-EPN4^(TQ) in japonica(geng)cultivar Lemont(LT)exhibited significantly improved EPN but decreased grain number and flag leaf size relative to LT.Haplotype analysis indicated that accessions with EPN4-1 had medium EPN,medium grain number,and medium grain weight,but had the highest grain yield among seven haplotypes,indicating that EPN4-1 is an elite haplotype of EPN4 for positive coordination of the three components of grain yield.Furthermore,accessions carrying the combination of EPN4-1 and haplotype GNP1-6 of GNP1 for grain number per panicle showed higher grain yield than those with other allele combinations.Therefore,pyramiding of EPN4-1 and GNP1-6 could be a preferred approach to obtain high yield potential in breeding.Yun Wang Xiaoqian Wang Laiyuan Zhai Sundus Zafar Congcong Shen Shuangbing Zhu Kai Chen Yun Wang Jianlong Xu 2024The Crop Journal2024,12,1:0
