text: Yo, check it out, here's the deal,
  We're talkin' 'bout the phylogenetic relationship, for real,
  Polyploid Hystrix in Triticeae, hold on tight,
  Gonna break it down with genes and sequences, alright?
  
  We got two single-copy nuclear genes in the mix,
  Acc1 and DMC1, gonna get our kicks,
  And chloroplast trnL-F, don't you forget,
  Gotta analyze them all, no time to fret.
  
  Six Hystrix taxa, they're up on the table,
  Gonna compare 'em with Leymus, it's a fable,
  Nine species of Leymus with NsXm,
  Four Elymus species, let's get it in.
  
  Thirteen diploid taxa, from seven genera,
  Gonna analyze their genes, it's gonna be extra,
  Phylogenetic analysis, here's what we found,
  Hystrix taxa, two types of genome, profound.
  
  Despite the similarities, both in looks and in style,
  Hystrix taxa got two types, gonna make you smile,
  StH type, like Elymus, that's the first,
  Hy. patula, holdin' it down, no need to rehearse.
  
  The other type, NsXm, like Leymus, it's true,
  Hy. californica, Hy. coreana, and the crew,
  Hy. duthiei, ssp. longearistata, and Hy. komarovii,
  All part of the NsXm gang, can't you see?
  
  Now let's talk genomes, where did they come from?
  Pseudoroegneria, Hordeum, and Psathyrostachys, drumroll, here they come,
  St, H, and Ns genomes in Hystrix, they're the donors,
  And the Xm genome, related to Agropyron, bonjour!
  
  Hold up, trnL-F data got somethin' to say,
  Maternal haplotype polymorphism, it's the way,
  Hystrix species, diverse in their mama's genes,
  Based on these results, we switch up the scenes.
  
  Hy. coreana, Hy. duthiei, ssp. longearistata, and the rest,
  They're movin' to Leymus, that's the best,
  Hy. patula, stand up tall, take a bow,
  You're rollin' with Elymus now, here's your crown.
  
  So that's the story, the phylogenetic tale,
  Hystrix and its relatives, we unveil,
  With genes and sequences, we break it down,
  Rappin' science, spreadin' knowledge all around.
