From: LncRNAs in polyploid cotton interspecific hybrids are derived from transposon neofunctionalization
Polyploidization-stimulated lncRNAs have potential function. a Table showing number of Gh lncRNA overlapped with parent and F1. Total number of SA and ST lncRNA of Gh expressed in leaf (threshold RPKM > 0.5). b Heatmap showing lncRNA expressed in diploid parents, F1, Gh, upland cotton land races, and cultivars. c The syntenic relationship of XLOC_409583 in Gossypium spp. Gray curves connect the homologous regions between the corresponding chromosomes. The syntenic region was defined as the region with at least four aligned coding genes. XLOC_409583 is located on the DT subgenome (on chromosome of GhDT D01), which is syntenic with the D diploid ancestor (on Gr Chr02). d Browser stacks for DNA methylation and RNA-seq of XLOC_409583 in Gr (diploid ancestor), F1 hybrid, and TM-1 (allotetraploid). e Representative photo of TM-1 plants treated with virus-induced gene silencing (VIGS) constructs TRV2: XLOC409583, TRV2, and TRV2:CLrV. f Relative expression of XLOC409583 in VIGS-treated cotton group. Plants treated with an empty vector were used as a control group. g Histogram showing the height of XLOC_409583 in VIGS-treated cotton group. An empty vector was used as a control group. n represents the number of plants in each block
