<jats:title>Abstract</jats:title><jats:p><jats:italic>Brassica rapa</jats:italic> L., which includes Chinese cabbage, turnip, and pak choi, has more complex flowering time regulation than does <jats:italic>Arabidopsis thaliana</jats:italic> due to the presence of multiple paralogous flowering time genes. <jats:italic>FLOWERING LOCUS C</jats:italic> (<jats:italic>FLC</jats:italic>) is one of the key genes regulating the flowering time, and <jats:italic>B. rapa</jats:italic> has four <jats:italic>FLC</jats:italic> paralogs. <jats:italic>BrFLC5</jats:italic> on the reference genome is deemed a pseudogene because of a mutation (from G to A) in the splice site of the third intron, but there are some accessions with a G nucleotide in the splice site. In this study, we genotyped 310 <jats:italic>B. rapa</jats:italic> accessions and found that 19 had homozygous and 81 had heterozygous putative functional <jats:italic>BrFLC5</jats:italic> alleles. Accessions of turnip showed the highest proportion with a functional <jats:italic>BrFLC5</jats:italic> allele. BrFLC5 acts as a floral repressor when overexpressed in <jats:italic>A. thaliana</jats:italic>. The <jats:italic>BrFLC5</jats:italic> expression level varied in pre-vernalized plants, and this transcriptional variation was not associated with the G/A polymorphism in the third intron. Three accessions having a higher <jats:italic>BrFLC5</jats:italic> expression in pre-vernalized plants had a 584-bp insertion in the promoter region. Many regions homologous to this 584-bp sequence are present in the <jats:italic>B. rapa</jats:italic> genome, and this 584-bp inserted region has tandem duplications of an AT-rich sequence in its central region. The possibility that a high expression of a functional <jats:italic>BrFLC5</jats:italic> could contribute to producing premature bolting-resistant lines in <jats:italic>B. rapa</jats:italic> vegetables is discussed.</jats:p>

<jats:title>Abstract</jats:title><jats:p>Population and genotype data are essential for genetic mapping. The multi-parent advanced generation intercross (MAGIC) population is a permanent mapping population used for precisely mapping quantitative trait loci. Moreover, genotyping-by-target sequencing (GBTS) is a robust high-throughput genotyping technology characterized by its low cost, flexibility, and limited requirements for information management and support. In this study, an 8-way MAGIC population was constructed using eight elite founder lines. In addition, GenoBaits Peanut 40K was developed and utilized for the constructed MAGIC population. A subset (297 lines) of the MAGIC population at the S2 stage was genotyped using GenoBaits Peanut 40K. Furthermore, these lines and the eight parents were analyzed in terms of pod length, width, area, and perimeter. A total of 27 single nucleotide polymorphisms (SNPs) were revealed to be significantly associated with peanut pod size-related traits according to a genome-wide association study. The GenoBaits Peanut 40K provided herein and the constructed MAGIC population will be applicable for future research to identify the key genes responsible for important peanut traits.</jats:p>

Fine mapping of the panicle length QTL qPL5 in rice
Pengfei Wang; Ling Ma; Daoyang Li; Bo Zhang; Tianhao Zhou; Xiangchun Zhou; Yongzhong Xing
<jats:title>Abstract</jats:title><jats:p>Panicle length is a crucial trait tightly associated with spikelets per panicle and grain yield in rice. To dissect the genetic basis of panicle length, a population of 161 recombinant inbred lines (RILs) was developed from the cross between an <jats:italic>aus</jats:italic> variety Chuan 7 (C7) and a tropical Geng variety Haoboka (HBK). C7 has a panicle length of 30 cm, 7 cm longer than that of HBK, and the panicle length was normally distributed in the RIL population. A total of six quantitative trait loci (QTLs) for panicle length were identified, and single QTLs explained the phenotypic variance from 4.9 to 18.1%. Among them, three QTLs were mapped to the regions harbored <jats:italic>sd1</jats:italic>, <jats:italic>DLT</jats:italic>, and <jats:italic>Ehd1</jats:italic>, respectively. To validate the genetic effect of a minor QTL <jats:italic>qPL5</jats:italic>, a near-isogenic F<jats:sub>2</jats:sub> (NIF<jats:sub>2</jats:sub>) population segregated at <jats:italic>qPL5</jats:italic> was developed. Interestingly, panicle length displayed bimodal distribution, and heading date also exhibited significant variation in the NIF<jats:sub>2</jats:sub> population. <jats:italic>qPL5</jats:italic> accounted for 66.5% of the panicle length variance. The C7 allele at <jats:italic>qPL5</jats:italic> increased panicle length by 2.4 cm and promoted heading date by 5 days. Finally, <jats:italic>qPL5</jats:italic> was narrowed down to an 80-kb region flanked by markers M2197 and M2205 using a large NIF<jats:sub>2</jats:sub> population of 7600 plants. LOC_Os05g37540, encoding a phytochrome signal protein whose homolog in <jats:italic>Arabidopsis</jats:italic> enlarges panicle length, is regarded as the candidate gene because a single-nucleotide mutation (C1099T) caused a premature stop codon in HBK. The characterization of <jats:italic>qPL5</jats:italic> with enlarging panicle length but promoting heading date makes its great value in breeding early mature varieties without yield penalty in rice.</jats:p>
