“…The regulation of flower color is a complex network; many factors affect the performance. For instance, plant hormones 35 , sugar transportation 36 , environmental stress 37 , retrotransposon activation 38 , carotenoid and anthocyanidin biosynthesis pathway 39 , and regulatory genes such as the MYB family 40 and MADS-box family 41 are all involved in the flower color regulation network. We identified 35 candidates within 10 QTL for 4 different color-related traits after a BLAST search of the NCBI nr database; 26 candidate genes located within 6 QTL related to 3 different traits: PetalMagArea, PetalMag and LipMag (Table 2 ).…”

Phalaenopsis spp. represent the most popular orchids worldwide. Both P. equestris and P. aphrodite are the two important breeding parents with the whole genome sequence available. However, marker–trait association is rarely used for floral traits in Phalaenopsis breeding. Here, we analyzed markers associated with aesthetic traits of Phalaenopsis orchids by using genome-wide association study (GWAS) with the F1 population P. Intermedia of 117 progenies derived from the cross between P. aphrodite and P. equestris. A total of 113,517 single nucleotide polymorphisms (SNPs) were identified in P. Intermedia by using genotyping-by-sequencing with the combination of two different restriction enzyme pairs, Hinp1 I/Hae III and Apek I/Hae III. The size-related traits from flowers were negatively related to the color-related traits. The 1191 SNPs from Hinp1 I/ Hae III and 23 simple sequence repeats were used to establish a high-density genetic map of 19 homolog groups for P. equestris. In addition, 10 quantitative trait loci were highly associated with four color-related traits on chromosomes 2, 5 and 9. According to the sequence within the linkage disequilibrium regions, 35 candidate genes were identified and related to anthocyanin biosynthesis. In conclusion, we performed marker-assisted gene identification of aesthetic traits with GWAS in Phalaenopsis orchids.

“…The effect of auxin on anthocyanin biosynthesis varies among species. Auxin inhibits anthocyanin biosynthesis in Arabidopsis , grape and apple (Ji et al, 2015; Jia et al, 2017; Liu et al, 2014), and promotes anthocyanin accumulation in immature peach and purple wheat grains (Li et al, 2021; Liu et al, 2019). The mechanism by which auxin regulates anthocyanin biosynthesis has been mainly studied in apple.…”

Auxin/indole‐3‐acetic acid (AUX/IAA) and auxin response factor (ARF) proteins are important components of the auxin signalling pathway, but their ubiquitination modification and the mechanism of auxin‐mediated anthocyanin biosynthesis remain elusive. Here, the ARF MdARF5‐1 was identified as a negative regulator of anthocyanin biosynthesis in apple, and it integrates auxin and ethylene signals by inhibiting the expression of the ethylene response factor MdERF3. The auxin repressor MdIAA29 decreased the inhibitory effect of MdARF5‐1 on anthocyanin biosynthesis by attenuating the transcriptional inhibition of MdERF3 by MdARF5‐1. In addition, the E3 ubiquitin ligases MdSINA4 and MdSINA11 played negative and positive regulatory roles in anthocyanin biosynthesis by targeting MdIAA29 and MdARF5‐1 for ubiquitination degradation, respectively. MdSINA4 destabilized MdSINA11 to regulate anthocyanin accumulation in response to auxin signalling. In sum, our data revealed the crosstalk between auxin and ethylene signals mediated by the IAA29‐ARF5‐1‐ERF3 module and provide new insights into the ubiquitination modification of the auxin signalling pathway.

“…Therefore, wheat Pm is a very serious problem, and an epidemic occurs every year. On the basis of many years of field observations, wheat landrace Guizi 1 (GZ1) is highly resistant to Pm [22]. In this study, genotyping-by-sequencing (GBS) technology was used to identify and map the Pm resistance genes in GZ1.…”

Background Wheat (Triticum aestivum L.) powdery mildew (Pm), which caused by Blumeria graminis f. sp. tritici (Bgt), is a destructive disease worldwide that causes severe yield losses in wheat. Resistant wheat cultivars easily lose their ability to effectively resist newly emerged Bgt strains; therefore, identifying new resistance genes is necessary for breeding resistant cultivars. Methods and ResultsGuizi 1 (GZ1) is a Chinese wheat cultivar with moderate and stable resistance to Pm. Genetic analysis indicated that the Pm resistance of GZ1 was controlled by a single dominant gene, designated PmGZ1. In total, 110 F 2 individual plants and their 2 parents were subjected to genotyping by sequencing (GBS), which yielded 23,134 high-quality single-nucleotide polymorphisms (SNPs). The SNP distributions across the 21 chromosomes ranged from 134 on chromosome 6D to 6288 on chromosome 3B. Chromosome 6A has 1866 SNPs, among which 16 are physically located between positions 307,802,221 and 309,885,836 in an approximate 2.3-cM region; this region also had the greatest SNP density. The average map distance between SNP markers was 0.1 cM. A quantitative trait locus (QTL) with a significant epistatic effect on Pm resistance was mapped to chromosome 6A. The logarithm of odds (LOD) value of PmGZ1 was 34.8, and PmGZ1 was located within the confidence interval marked by chr6a-307802221 and chr6a-309885836. Moreover, 74.7% of the phenotypic variance was explained by PmGZ1. Four candidate genes (which encoded two TaAP2-A and two actin proteins) were annotated maybe as resistance genes. Conclusions The present results provide valuable information for wheat genetic improvement, QTL fine mapping, and candidate gene validation.
