“…Candidate gene-based association analysis revealed that major genes controlling the flowering time, FLOWERING LOCUS C (FLC), FRIGIDA (FRI), VERNALIZATION-INSENSITIVE 3 (VIN3) and CRYPTOCHROME 2 (CRY2), are associated with natural variation (Shindo et al, 2005;Balasubramanian et al, 2006;Wollenberg and Amasino, 2012). After developing a number of accessions with the SNP information, the genome-wide association of genes regulating flowering time was identified by GWAS (Atwell et al, 2010;Li et al, 2014;Sasaki et al, 2015;The 1001Genomes Consortium, 2016Zan and Carlborg, 2018). GWAS on flowering time have been conducted in various crops other than Arabidopsis, leading to the discovery of new loci associated with flowering time (maize: Bouchet et al, 2013, rice: Huang et al, 2012, barley: Muñoz-Amatriaín et al, 2014, soybean: Zhang et al, 2015b, rapeseed: Xu et al, 2015, common bean: Moghaddam et al, 2016.…”

Genome-wide association study (GWAS) is a powerful approach to identify the genetic factors underlying the intraspecific phenotypic variations. Recent advances in DNA sequencing technology, including next generation sequencing has enabled us to easily genotype high density genome-wide SNPs. In addition, many accessions of various plant species have been widely collected in recent years. These genetic resources have made GWAS a markedly more popular approach for investigation of natural variations occurring in various traits using large populations. In addition to genotyping technology, advances in high-throughput phenotyping technologies have enabled us to acquire variation data on a large number of accessions characterized for various traits, including not only the field traits (e.g., yield and disease resistance) but also molecular traits (e.g., gene expression level and metabolite content). Thus, it is possible to expand the range of application of GWAS and enhance the detection power of genomic association. In this review, we summarize recent GWAS of various agronomic traits at field and molecular scale, following which we highlight the integration approach involving GWAS and high-throughput phenotyping technologies including transcriptome, ionome and metabolome.

“…Aromatic polyimides are a kind of high-performance polymers with high thermal stability, chemical resistance, excellent electronic and mechanical properties, [1][2][3][4] and have been widely used in many fields such as aerospace, microelectronics, optoelectronics, and composites. For some applications, it is desirable to use polyimides which are required to be soluble in spin coating and casting processes.…”

A series of novel soluble polyimides was synthesized from commercially available 2,4,6-triaminopyrimidine (TAP), 2,2-bis(3,4-dicarboxylphenyl) hexafluoropropane dianhydride (6FDA), ,!-aminopropylpoly(dimethylsiloxane) and 1,3-bis(3-aminophenoxy)benzene. TAP is the branched monomer, and polymerization process had been improved in three ways by using TAP to prepare soluble polyimides. The polyimides were characterized by Fourier transform infrared spectra, proton nuclear magnetic resonance, ultraviolet-visible spectrometer analysis, wide-angle X-ray diffraction, and sizeexclusion chromatography with multiangle laser light-scattering detection. The branched polyimides showed excellent solubility both in strong polar solvents and in common low-boiling point solvents. Differential scanning calorimetric and thermogravimetric analyses showed high glass transition temperatures and excellent thermal stability for branched polyimides with moderate content of TAP. Polyimide membranes were formed at relatively low temperature, and the mechanical properties were tested. These results ensure that soluble polyimides with moderate content of TAP showed outstanding combined features and are desirable candidate materials for advanced applications.
