Other claims from this paper (16)
- Method / resource The linkage map is the largest to date, spanning 1825.56 cM with 7987 SNP markers.
- Observation Eight QTLs were mapped for days to flowering.
- Observation Four QTLs were mapped for growth habit.
- Observation Mapped QTLs harboured 78 pigeonpea orthologs of Arabidopsis flowering time genes.
- Observation QTL-seq found a single linked QTL for both traits on chromosome 3 with 15 variant-bearing genes.
- Observation The 91 genes clustered mainly into autonomous, photoperiod and epigenetic pathways.
- Observation GWAS found 39 flowering-time associations in QTL regions.
- Observation Nine consistent associations formed nine haplotypes, including five late haplotypes.
- Observation Two of the consistent haplotypes were early.
- Observation One consistent haplotype was super-early.
- Observation One consistent haplotype was medium duration.
- Mechanism Multiple genes explained the allelic effect range and multiple LD blocks.
- Observation The linked chromosome 3 QTL was fine-mapped to 0.24 Mb with LOD 8.56 and 36.47% variance explained.
- Observation ICPL 20338 carries a 10-bp deletion in the first exon of TFL1.
- Mechanism The TFL1 deletion may alter interactions with Apetala1 and Leafy, producing determinate growth habit and early flowering.
- Recommendation The deletion marker could serve as a foreground marker for breeding early-flowering pigeonpea.
