Quality and yield are the primary concerns in kiwifruit breeding,but research on the genetic mechanisms of fruit size,shape,and ascorbic acid(ASA)content is currently very limited,which restricts the development of kiwifruit molecular breeding.In this study,we obtained a total of 8.88 million highly reliable single nucleotide polymorphism(SNP)markers from 140 individuals from the natural hybrid offspring of Actinidia eriantha cv.‘White’using whole genome resequencing technology.A genome-wide association study was conducted on eight key agronomic traits,including single fruit weight,fruit shape,ASA content,and the number of inflorescences per branch.A total of 59 genetic loci containing potential functional genes were located,and candidate genes related to single fruit weight,fruit length,ASA content,number of inflorescences per branch and other traits were identified within the candidate interval,such as AeWUSCHEL,AeCDK1(cell cycle dependent kinase),AeAO1(ascorbic oxidase)and AeCO1(CONSTANS-like 4).After constructing an RNAi vector for AeAO1 and injecting it into the fruit of cv.‘Midao 31’to interfere with the expression of the AeAO1 gene,the results showed that the activity of ascorbic oxidase in the fruit of‘Midao 31’significantly decreased,while the content of ASA significantly increased.This study provides valuable insights into the genetic basis of variation in A.eriantha fruit traits,which may benefit molecular marker-assisted breeding efforts.

Plant height(PH)is one of the most important components of the plant ideotype,and it affects plant biomass,yield,lodging resistance,and the ability to use mechanized harvesting.Since many complex pathways controlling plant growth and development remain poorly understood,we are still unable to obtain the most ideal plants solely through breeding efforts.PH can be influenced by genotype,plant hormonal regulation,environmental conditions,and interactions with other plants.Here,we comprehensively review the factors influencing PH,including the regulation of PH-related developmental processes,the genetics and qtls contributing to PH,and the hormone-regulated molecular mechanisms for PH.Additionally,the symbiotic influence of grafting on PH is discussed,focusing on the molecular regulation of gene expression and genetics.Finally,we propose strategies for applying recent findings to breeding for better PH,highlight some knowledge gaps,and suggest potential directions for future studies.

Salinity threatens soybean germination,growth and production.The germination stage is a key period in the life of soybean.Wild soybean contains many genes related to stress resistance that are valuable resources for the genetic improvement of soybean.To identify the genetic loci of wild soybean that are active during seed germination under salt stress,two populations,a soybean interspecific hybrid population comprising 142 lines and a natural population comprising 121 wild soybean accessions,were screened for three germination-related traits in this study.By using single-nucleotide polymorphism(SNP)markers with three salt tolerance indices,25 quantitative trait loci(qtls),21 significant SNPs(–log_(10)(P)≥4.0)and 24 potential SNPs(3.5qtls.According to the gene functional annotations of the W05 genome and salt-induced gene expression qRT-PCR analysis,GsAKR1 was selected as a candidate gene that responded to salt stress at the germination stage in the wild soybean.These results could contribute to determining the genetic networks of salt tolerance in wild soybean and will be helpful for molecular marker-assisted selection in the breeding of salt-tolerant soybean.

As essential B vitamin for humans, folates accumulation in edible parts of crops, such as maize kernels, Is of great importance for human health. But its breeding is always limited by the prohibitive cost of folate profiling. The molecular breeding is a more executable and efficient way for folate fortification, but is limited by the molecular knowledge of folate regulation. Here we report the genetic mapping of folate quantitative trait loci (qtls) using a segregated population crossed by two maize lines, one high in folate (GEMS31) and the other low in folate (DAN3130). Two folate qtls on chromosome 5 were obtained by the combination of F2 whole-exome sequencing and F3 kernel-folate profiling. These two qtls had been confirmed by bulk segregant analysis using F6 pooled DNA and F7 kernel-folate profiling, and were overlapped with qtls identified by another segregated population. These two qtls contributed 41.6% of phenotypic variation of 5-formyltetrahydrofolate, the most abundant storage form among folate derivatives in dry maize grains, in the GEMS31×DAN3130 population. Their fine mapping and functional analysis will reveal details of folate metabolism, and provide a basis for marker-assisted breeding aimed at the enrichment of folates in maize kernels.

Erianthus produces substantial biomass,exhibits a good Brix value,and shows wide environmental adaptability,making it a potential biofuel plant.In contrast to closely related sorghum and sugarcane,Erianthus can grow in degraded soils,thus releasing pressure on agricultural lands used for biofuel production.However,the lack of genomic resources for Erianthus hinders its genetic improvement,thus limiting its potential for biofuel production.In the present study,we generated a chromosome-scale reference genome for Erianthus fulvus Nees.The genome size estimated by flow cytometry was 937 Mb,and the assembled genome size was 902 Mb,covering 96.26%of the estimated genome size.A total of 35065 proteincoding genes were predicted,and 67.89%of the genome was found to be repetitive.A recent wholegenome duplication occurred approximately 74.10 million years ago in the E.fulvus genome.Phylogenetic analysis showed that E.fulvus is evolutionarily closer to S.spontaneum and diverged after S.bicolor.Three of the 10 chromosomes of E.fulvus formed through rearrangements of ancestral chromosomes.Phylogenetic reconstruction of the Saccharum complex revealed a polyphyletic origin of the complex and a sister relationship of E.fulvus with Saccharum sp.,excluding S.arundinaceum.On the basis of the four amino acid residues that provide substrate specificity,the E.fulvus SWEET proteins were classified as monoand disaccharide sugar transporters.Ortho-QTL genes identified for 10 biofuel-related traits may aid in the rapid screening of E.fulvus populations to enhance breeding programs for improved biofuel production.The results of this study provide valuable insights for breeding programs aimed at improving biofuel production in E.fulvus and enhancing sugarcane introgression programs.

作者： ZHENG XianHu KUANG YouYi LV WeiHua CAO DingChen ZHANG XiaoFeng LI Chao LU CuiYun SUN XiaoWen Heilongjiang River Fisheries Research Institute Chinese Academy of Fishery Sciences College of Fisheries and Life Science Shanghai Ocean University

The ability to detect and identify quantitative trait loci (qtls) in a single population is often limited. Analyzing multiple populations in QTL analysis improves the power of detecting qtls and provides a better understanding of their functional allelic variation and distribution. In this study, a consensus map of the common carp was constructed, based on four populations, to compare the distribution and variation of qtls. The consensus map spans 2371.6 cM across the 42 linkage groups and comprises 257 microsatellites and 421 SNPs, with a mean marker interval of 3.7 cM/marker. Sixty-seven qtls affecting four growth traits from the four populations were mapped to the consensus map. Only one QTL was common to three populations, and nine qtls were detected in two populations. However, no QTL was common to all four populations. The results of the QTL comparison suggest that the qtls are responsible for the phenotypic variability observed for these traits in a broad array of common carp germplasms. The study also reveals the different genetic performances between major and minor genes in different populations.

Background:In this study,we aimed to investigate the molecular basis of lactation as well as to identify the genetic factors that influence milk yield and composition in goats.To achieve these two goals,we have analyzed how the mRNA profile of the mammary gland changes in seven Murciano-Granadina goats at each of three different time points,i.e.78 d(T1,early lactation),216 d(T2,late lactation)and 285 d(T3,dry period)after parturition.Moreover,we have performed a genome-wide association study(GWAS)for seven dairy traits recorded in the 1st lactation of 822 Murciano-Granadina goats.Results:The expression profiles of the mammary gland in the early(T1)and late(T2)lactation were quite similar(42 differentially expressed genes),while strong transcriptomic differences(more than one thousand differentially expressed genes)were observed between the lactating(T1/T2)and non-lactating(T3)mammary glands.A large number of differentially expressed genes were involved in pathways related with the biosynthesis of amino acids,cholesterol,triglycerides and steroids as well as with glycerophospholipid metabolism,adipocytokine signaling,lipid binding,regulation of ion transmembrane transport,calcium ion binding,metalloendopeptidase activity and complement and coagulation cascades.With regard to the second goal of the study,the performance of the GWAS allowed us to detect 24 quantitative trait loci(qtls),including three genome-wide significant associations:QTL1(chromosome 2,130.72-131.01 Mb)for lactose percentage,QTL6(chromosome 6,78.90-93.48 Mb)for protein percentage and QTL17(chromosome 17,11.20 Mb)for both protein and dry matter percentages.Interestingly,QTL6 shows positional coincidence with the casein genes,which encode 80%of milk proteins.Conclusions:The abrogation of lactation involves dramatic changes in the expression of genes participating in a broad array of physiological processes such as protein,lipid and carbohydrate metabolism,calcium homeostasis,cell death and tissue remodeling,as well as immunity.We also conclude that

Genetic Improvement of Willow for Bioenergy and Biofuels

Journal of Integrative Plant Biology 2011年第2期53卷 151-165页

Willows （Salix spp.） are a very diverse group of catkin-bearing trees and shrubs that are widely distributed across temperate regions of the globe. Some species respond well to being grown in short rotation coppice （SRC） cycles, which are much shorter than conventional forestry. Cop- picing reinvigorates growth and the biomass rapidly accumulated can be used as a source of renewable carbon for bioenergy and biofuels. As SRC willows re-distribute nutrients during the perennial cycle they require only minimal nitrogen fertilizer for growth. This results in fuel chains with potentially high greenhouse gas reductions. To exploit their potential for renewable energy, willows need to be kept free of pests and diseases and yields need to be improved without significantly increasing the requirements for fertilizers and water. The biomass composition needs to be optimized for different end-uses. Yields also need to be sustainable on land less productive for food crops to reduce conflicts over land use. Advances in understanding the physiology and growth of willow, and in the identification of genes underlying key traits, are now at the stage where they can start to be used in breeding programs to help achieve these goals.

Heading date in rice is a typical quantitative trait controlled by multiple quantitative trait loci （qtls）. It is mainly regulated by environmental factors such as photoperiod and temperature （Izawa, 2007）. Many qtls for heading date have been identified using different mapping populations and methods （http：// ***/qtl）. Up to date, several major heading date qtls have been cloned by map-based cloning strategy （Yano et al., 2000; Takahashi et al., 2001; Kojima et al., 2002; Doi et al., 2004; Xue et al., 2008; Wei et al., 2010; Yan et al.,

The present study was conducted to identify quantitative trait loci （qtls） for leaf size traits in IR64 introgression lines （INLs）. For this purpose, selected F2 populations derived from crosses between recurrent parent IR64 and its derived INLs, unique for leaf length and leaf width, were used to confirm qtls. A total of eight qtls, mapped on three chromosomes, were identified for the four leaf size traits in six F2 populations. A QTL for leaf length, qLLnpt-1, in HKL69 was identified around simple sequence repeat （SSR） marker RM3709 on chromosome 1. Two qtls for flag leaf length, qFLLnpt-2 and qFLLnpt-4, in HFG39 were indentified on chromosomes 2 and 4, respectively. For flag leaf width, a QTL, qFLWnpt-4, in HFG39 was identified around RM17483 on chromosome 4. While another QTL for flag leaf width, qFLWnpt-1, in HFG27 was identified around RM3252 on chromosome 1. A QTL for leaf width, qLWnpt-2, in HKL75 was identified around RM7451 on chromosome 2. For leaf width, two qtls, qLWnpt-4a, qLWnpt-4b, in HKL48 and HKL99 were identified around RM7208 and RM6909, respectively on chromosome 4. Results from this study suggest the possibilities to use marker-assisted selection and pyramiding these qtls to improve rice water productivity.
