Twenty short-statured maize inbred lines were collected from CIMMYT India and Mexico through the Plant Breeding Division, Bangladesh Agricultural Research Institute (BARI), Gazipur. The experiment was conducted from November 2020 to April 2021 in three different agroecological regions such as BARI, Gazipur, RARS Barisal and RARS Rangpur. Seven inbred lines were selected on the basis of genetic diversity and per se performance and they were crossed separately in a 7 × 7 half diallel fashion, producing 21F1 hybrids in 2019 which were evaluated at three locations. However, variances due to GCA were much higher in magnitude than SCA for all the characters indicating preponderance of additive gene effects on the inheritance of these characters. Two parents viz., P3 (CML33) and P4 (CML41) were good general combiners and two crosses viz., P4 × P5 (CML41 × CML31) and P5 × P7 (CML31 × CML124) expressed significant positive SCA effects coupled with significant positive heterosis for grain yield and for most of the yield contributing characters over the two commercial check varieties BHM 9 and NK40. Four crosses: P1 × P5 (CML116 × CML31), P1 × P6 (CML116 × CML32), P2 × P6 (CML72 × CML32) and P3 × P4 (CML33 × CML41), exhibited significant and negative SCA effects for both plant and ear height which were desirable for short stature. Genotypes x location interaction was also significant for maximum characters, suggesting that genotypes interacted significantly in different environments. 展开更多

This study investigated the relationship between parental cognitive ability and child logical reasoning ability,and the role of academic expectation and family environment in that relationship.Based on the 2020 China Family Panel Studies(CFPS)data,1491 children(girls ratio=53.78%;average grade=6.023 years,school grade standard deviation=1.825 years).Results following multiple regression model(OLS)show that the higher the parental cognitive ability,the higher the children’s logical reasoning ability.Secondly,parental academic expectation serves as a mediator between their cognitive ability and children’s logical reasoning ability for higher logical reasoning by children.Third,a possible family environment acts as a mediator in the relationship between parents’cognitive ability and children’s logical reasoning ability to be higher.We conclude from thesefindings that parents with high cognitive abilities can enhance their children’s logical reasoning skills not only by setting higher academic expectations,but also by cultivating a supportive family environment.Thesefindings imply a need for intervention to improve family quality of life to enhance children’s thinking abilities to optimize their academic learning. 展开更多

The low egg production of goose greatly limits the development of the industry.China possesses the most abundant goose breeds resources.In this study,genome resequencing data of swan goose(Anser cygnoides)and domesticated high and low laying goose breeds(Anser cygnoides domestiation)were used to identify key genes related to egg laying ability in geese and verify their functions.Selective sweep analyses revealed 416 genes that were specifically selected during the domestication process from swan geese to high laying geese.Furthermore,SNPs and Indels markers were used in GWAS analyses between high and low laying breed geese.The results showed that RTCB,BPIFC,SYN3,SYNE1,VIP,and ESR1 may be related to the differences in laying ability of geese.Notably,only ESR1 was identified simultaneously by GWAS and selective sweep analysis.The genotype of Indelchr3:54429172,located downstream of ESR1,was confirmed to affect the expression of ESR1 in the ovarian stroma and showed significant correlation with body weight at first egg and laying frequency of geese.CCK-8,EdU,and flow cytometry confirmed that ESR1 can promote the apoptosis of goose pre-hierarchical follicles ganulosa cells(phGCs)and inhibit their proliferation.Combined with transcriptome data,it was found ESR1 involved in the function of goose phGCs may be related to MAPK and TGF-beta signaling pathways.Overall,our study used genomic information from different goose breeds to identify an indel located in the downstream of ESR1 associated with goose laying ability.The main pathways and biological processes of ESR1 involved in the regulation of goose laying ability were identified by cell biology and transcriptomics methods.These results are helpful to further understand the laying ability characteristics of goose and improve the egg production of geese. 展开更多

AIM:To investigate the underlying factors by establishing a new paradigm for assessing control ability under stereopsis testing conditions.METHODS:This was a prospective observational study.We evaluated the control ability of intermittent exotropia(IXT)patients in three conditions:natural 2D optotype viewing,2D optotype viewing with polarized glasses,and 3D optotype viewing with polarized glasses.Recording with a smartphone,we captured videos to analyze the accurate time of spontaneous exodeviation and subsequent realignment before and after breaking fusion.Additionally,the correlation of stereopsis were also analyzed.RESULTS:A total of 48 patients(age range:4-33y;54.17%male)participated in the study.When viewing 3D optotypes with polarized glasses,their median control scores were 1(interquartile range,0-4)at distance and 0(0-1)at near.These scores were significantly better than those observed under natural viewing conditions,which were 2.5(1-5)at a distance and 1(0-3)at near(Friedman test,P=0.049).Furthermore,those subjects who exhibited exophoria(realignment within 2 seconds)while viewing 3D optotypes with polarized glasses were more likely to have measurable stereo vision(Kendall’sτb=-0.344,P=0.018).CONCLUSION:IXT patients exhibit enhanced control ability when using polarized glasses to view 3D optotypes,notably improving realignment capabilities.This expands our understanding of current tests and offers a potentially sensitive method for assessing IXT severity. 展开更多

The glass-forming ability(GFA)of metallic glasses is a key scientific challenge in their development and application,with compositional dependence playing a crucial role.Experimental studies have demonstrated that the addition of specific minor elements can greatly enhance the GFA of parent alloys,yet the underlying mechanism remains unclear.In this study,we use the ZrCuAl system as a model to explore how the addition of minor Al influences the crystallization rate by modulating the properties of the crystal-liquid interface,thereby affecting the GFA.The results reveal that the minor addition of Al significantly reduces the crystal growth rate,a phenomenon not governed by particle density fluctuations at the interface.The impact of minor element additions extends beyond a modest increase in crystal-unfavorable motifs in the bulk supercooled liquid.More importantly,it leads to a significant enrichment of these motifs at the crystal-supercooled liquid interface,forming a dense topological network of crystal-unfavorable structures that effectively prevent the growth of the crystalline interface and enhance GFA.Our results provide valuable insights for the design and development of high-performance metallic glasses. 展开更多

Recent studies have shown that mucilage secretion from aerial roots is an essential feature of modern maize inbred lines,with some retaining the nitrogen-fixing capabilities of ancient landraces.To explore the genetic basis of nitrogen fixation in mucilage and its evolution from teosinte(Zea mays ssp.mexicana)to modern maize,we developed a recombinant inbred line(RIL)population from teosinte and cultivated it under low-nitrogen conditions.Large-scale,multi-year,and multi-environment analyses of RIL-Teo,Doubled Haploid-A(DH-A),Doubled Haploid-B(DH-B),and association populations led to the identification of 15 quantitative trait loci(QTL),68 quantitative trait nucleotides(QTN),and 59 candidate genes linked to mucilage secretion from aerial roots.Functional verification of the candidate gene ZmAco3,which is associated with mucilage secretion in aerial roots,demonstrated that deletion of this gene resulted in a reduction in mucilage secretion in aerial roots.In addition,most maize inbred lines exhibited stronger mucilage secretion from aerial roots under low-nitrogen conditions than under normal-nitrogen conditions.We categorized mucilage secretion into constitutive and low-nitrogen-inducible types.Through genotype-by-environment interaction studies,8 QTL,16 QTN,and 19 candidate genes were identified,revealing the genetic mechanisms underlying mucilage secretion under low-nitrogen conditions.These findings provide a comprehensive genetic analysis of the mucilage-secreting ability of maize aerial roots,contributing to our understanding of nitrogen fixation and offering potential avenues for enhancing nitrogen fixation in modern maize lines.This research advances knowledge of plant nutrient acquisition strategies and has implications for sustainable agricultural practices. 展开更多
