| 3 | Genome-wide association study and metabolic pathway prediction of barrenness in maize as a response to high planting density显示文摘Increasing the planting density is one way to enhance grain production in maize.However,high planting density brings about growth and developmental defects such as barrenness,which is the major factor limiting grain yield.In this study,the barrenness was characterized in an association panel comprising 280 inbred lines under normal(67500 plants ha–1,ND)and high(120000 plants ha–1,HD)planting densities in 2017 and 2018.The population was genotyped using 776254 single nucleotide polymorphism(SNP)markers with criteria of minor allele frequency>5%and<20%missing data.A genome-wide association study(GWAS)was conducted for barrenness under ND and HD,as well as the barrenness ratio(HD/ND),by applying a Mixed Linear Model that controls both population structure and relative kinship(Q+K).In total,20 SNPs located in nine genes were significantly(P<6.44×10–8)associated with barrenness under the different planting densities.Among them,seven SNPs for barrenness at ND and HD were located in two genes,four of which were common under both ND and HD.In addition,13 SNPs for the barrenness ratio were located in seven genes.A complementary pathway analysis indicated that the metabolic pathways of amino acids,such as glutamate and arginine,and the mitogen-activated protein kinase(MAPK)signaling pathway might play important roles in tolerance to high planting density.These results provide insights into the genetic basis of high planting density tolerance and will facilitate high yield maize breeding. | ZHANG Xu-huan LIU Hao MA Xu-hui ZHOU Gu-yi RUAN Hong-qiang CUI Hong-wei PANG Jun-ling KHAN Ullah Siffat ZONG Na WANG Ren-zhong LENG Peng-fei ZHAO Jun | 2022 | Journal of Integrative Agriculture2022，21，12： | 0 |
| 4 | Characterization of transgenic wheat lines expressing maize ABP7 involved in kernel development显示文摘Wheat is one of the major food crops in the world.Functional validation of the genes in increasing the grain yield of wheat by genetic engineering is essential for feeding the ever-growing global population.This study investigated the role of ABP7,a bHLH transcription factor from maize involved in kernel development,in regulating grain yield-related traits in transgenic wheat.Molecular characterization showed that transgenic lines HB123 and HB287 contained multicopy integration of ABP7 in the genome with higher transgene expression.At the same time,QB205 was a transgenic event of single copy insertion with no significant difference in ABP7 expression compared to wild-type(WT) plants.Phenotyping under field conditions showed that ABP7 over-expressing transgenic lines HB123 and HB287 exhibited improved grain yield-related traits(e.g.,grain number per spike,grain weight per spike,thousand-grain weight,grain length,and grain width) and increased grain yield per plot,compared to WT plants,whereas line QB205 did not.In addition,total chlorophyll,chlorophyll a,chlorophyll b,and total soluble sugars were largely increased in the flag leaves of both HB123and HB287 transgenic lines compared to the WT.These results strongly suggest that ABP7 positively regulates yieldrelated traits and plot grain yield in transgenic wheat.Consequently,ABP7 can be utilized in wheat breeding for grain yield improvement. | Zaid CHACHAR Siffat Ullah KHAN ZHANG Xu-huan LENG Peng-fei ZONG Na ZHAO Jun | 2023 | Journal of Integrative Agriculture2023，22，2： | 0 |
