Dear Editor,Ensuring food security with finite resources and environmental impacts is a new challenge in sustainable agriculture(Yu et al.,2022).It is therefore essential to develop suitable rice varieties for resource-saving and environmentally friendly cultivation(Luo et al.,2019;Yu et al.,2022).Upland rice,which evolves many green characters for rice sustainable cultivation(e.g.,drought resistance,the usage efficiency of nitrate,the good capacity of direct seeding,etc.),is therefore an important germplasm in rice breeding(Luo et al.,2019).However,the origination and evolution of upland rice,as well as its green genetic resource,remain mysterious(Xia et al.,2019).

Potato(Solanum tuberosum)is the most consumed non-cereal food *** commercial potato cultivars are autotetraploids with highly heterozygous genomes,severely hampering genetic analyses and *** leveraging the state-of-the-art sequencing technologies and polyploid graph binning,we achieved a chromosome-scale,haplotype-resolved genome assembly of a cultivated potato,Cooperation-88(C88).lntra-haplotype comparative analyses revealed extensive sequence and expression differences in this tetraploid *** identified haplotype-specific pericentromeres on chromosomes,suggesting a distinct evolutionary trajectory of potato homologous ***,we detected double reduction events that are unevenly distributed on haplotypes in 1021 of 1034 selfing progeny,a feature of autopolyploid *** distinguishing maternal and paternal haplotype sets in C88,we simulated the origin of heterosis in cultivated tetraploid with a survey of 3110 tetra-allelic loci with deleterious mutations,which were masked in the heterozygous condition bytwo *** study provides insights into the genomic architecture of autopolyploids and will guide their breeding.

高原鼢鼠(Myospalax baileyi)作为青藏高原唯一营地下生活的鼠类,其造丘活动不仅能影响草地群落演替的方向和进程,而且对鼠丘土壤养分含量和分配造成空间异质性。关于不同形成时期的高原鼢鼠鼠丘养分含量及在垂直高度的分配规律研究报道尚少。基于此本研究以不同形成时期的鼢鼠鼠丘为研究对象,对鼠丘土壤养分含量及空间分配规律进行探讨。结果表明:随着鼠丘形成时间的推移,土壤养分总体表现为:1年鼠丘>多年鼠丘>对照区;与非鼠丘区相比,随着土壤土层增加,土壤养分未呈现规律性的变化。其中,土壤全氮和速效氮含量表现为1年鼠丘>3年鼠丘>5年鼠丘>对照区;0—10cm土壤全磷和速效磷含量变化总体表现为多年鼠丘>1年鼠丘>对照区,10—30cm土层1年鼠丘土壤中全磷和速效磷含量最高。土壤速效钾和有机质含量随着鼠丘形成时间推移总体表现为:1年鼠丘>5年鼠丘>3年鼠丘;其中在10—30cm土层,1年鼠丘速效钾和有机质含量显著高于多年鼠丘和对照区。由此可见,高原鼢鼠造丘活动能显著改变土壤养分分配格局,短期内形成养分富集的肥力岛,为鼠丘土壤种子库中种子的萌发和植被生长提供必需的养分保证。

新冠德尔塔病毒通过境外输入在广州、南京、扬州等地区局部散发.在中国政府强有力的监管防控政策和全市人民的密切配合下,通过“追踪-检测-隔离”清零防控模式,找出“零号病人”,确定传染链,进行全员核酸检测精准筛查密切接触者,并及时采取不同等级的隔离措施,阻断传染链,多地小规模的聚集性疫情在近一个月内能够得以控制.本文以扬州市COVID-19疫情防控为研究对象,通过区分社区和集中隔离点的感染者,建立了具有隔离和大规模检测的传染病模型,研究当前清零模式成功的机制,并利用相关参数模拟了扬州的抗疫成功的过程.利用新模型,我们比较分析“躺平”模式,消极模式以及推迟当前清零政策等,研究了多种情形下的疫情发展趋势及其影响.
