“…Based on the Gramene website ( http://www.gramene.org/markers/ ), the BLAST ( http://blast.ncbi.nlm.nih.gov/Blast.cgi ), and the China Rice Data Center database ( http://www.ricedata.cn/gene/list/1499.htm ), we compared the QTLs identified in this study with the QTLs reported previously controlling FLA. The position range of five QTLs was overlapped with the flanking regions of four QTLs and one gene ( OsLIC ) reported previously (Li et al, 1999 ; Dong et al, 2003 ; Wang et al, 2008 ; Zhang et al, 2012 , 2013 ; Ham et al, 2019 ) ( Supplementary Table 12 ), and the remaining one QTL qFLA2 was newly identified in this study.…”

“…Early research has shown that the FLA trait is controlled by a pair of major genes and a number of minor gene pairs, with a small angle being partially dominant (Shen, 1983 ). To date, 63 quantitative trait loci (QTLs) for FLA have been identified based on linkage analysis, including 9, 7, 6, 4, 4, 5, 4, 7, 6, 0, 8, and 3 on chromosomes 1–12, respectively ( Supplementary Table 1 ) (Li et al, 1999 ; Yan et al, 1999 ; Dong et al, 2003 ; Kobayashi et al, 2003 ; Luo et al, 2008 ; Zhang et al, 2008 , 2013 ; Cai, 2009 ; Hu et al, 2012 ; Wang et al, 2012 ; Bian et al, 2014 ; Zou et al, 2014 ; Zhu et al, 2016 ; Ham et al, 2019 ). In addition, 100 QTLs for FLA have been detected based on association analysis (Huang et al, 2010 ; Chen et al, 2012 ; Lu et al, 2015 ; Dong H. J. et al, 2018 ; Dong Z. Y. et al, 2018 ).…”

Flag leaf angle (FLA) is an important outcrossing trait affecting the hybrid seed production in rice (Oryza sativa L.). Natural variation of FLA has been reported in rice, but the molecular basis for this variation is largely unknown. In this study, we investigated the phenotypic values of FLA in 353 rice natural accessions in six environments, which indicated that there was abundant phenotypic variation. We performed a genome-wide association study on FLA using 1.3 million single nucleotide polymorphisms (SNPs). A total of six quantitative trait loci (QTLs) were identified significantly associated with FLA, of which five were located in previously reported QTLs/genes and one was novel. We identified two causal gene loci for FLA, namely, OsFLA6 and OsFLA2; OsFLA6 was co-localized with the gene OsLIC. In addition, the accessions with large and small FLA values have corresponding high and low OsFLA6 expressions. OsFLA2TT allele could increase significantly the seed setting percentage in hybrid F1 seed production by field experiment. We also confirmed that the allele OsFLA2TT increased the FLA compared with that of the isogenic line carrying allele OsFLA2CC by transgenic complementation experiment. The allele frequencies of OsFLA6GGand OsFLA2TT decreased gradually with an increase in latitude in the Northern Hemisphere. Our results should facilitate the improvement of FLA of parents of hybrid rice.

“…Wheat flag leaf morphological traits are quantitative traits influenced by many environmental factors and controlled by multiple genes [6][7][8]. Many genes and QTLs that control leaf size and angle have been reported in rice [9][10][11][12][13]. For example, the mutation of OsDWARF gene resulted in the defect of brassinosteroid synthesis, which led to the reduction of plant height and the upright leaves [14].…”

Flag leaf is an important organ for photosynthesis of wheat plants, and a key factor affecting wheat yield. In this study, quantitative trait loci (QTL) for flag leaf morphological traits in wheat reported since 2010 were collected to investigate the genetic mechanism of these traits. Integration of 304 QTLs from various mapping populations into a high-density consensus map composed of various types of molecular markers as well as QTL meta-analysis discovered 55 meta-QTLs (MQTL) controlling morphological traits of flag leaves, of which 10 MQTLs were confirmed by GWAS. Four high-confidence MQTLs (MQTL-1, MQTL-11, MQTL-13, and MQTL-52) were screened out from 55 MQTLs, with an average confidence interval of 0.82 cM and a physical distance of 9.4 Mb, according to the definition of hcMQTL. Ten wheat orthologs from rice (7) and Arabidopsis (3) that regulated leaf angle, development and morphogenesis traits were identified in the hcMQTL region using comparative genomics, and were speculated to be potential candidate genes regulating flag leaf morphological traits in wheat. The results from this study provides valuable information for fine mapping and molecular markers assisted selection to improve morphological characters in wheat flag leaf.
