Verbatim
e0“the tetraploid species Gossypium hirsutum and G. barbadense were found to harbor 22 and 23 genes, respectively, representing a substantial expansion compared to the 12 and 13 genes identified in the diploid progenitors G. arboreum and G. raimondii”

Other claims from this paper (11)
- Observation A systematic analysis identified 70 genes related to SA biosynthesis across four cotton species.
- Observation Tetraploid Gossypium hirsutum harbors 22 SA biosynthesis genes, an expansion relative to the diploid progenitors.
- Observation The diploid progenitor G. arboreum has 12 SA biosynthesis genes.
- Observation The diploid progenitor G. raimondii has 13 SA biosynthesis genes.
- Observation SA biosynthesis genes are uniformly distributed across the A/D sub-genomes of tetraploid cotton with extensive interspecific collinearity.
- Mechanism Whole-genome and segmental duplication are the dominant drivers of expansion of the SA biosynthesis gene family in cotton.
- Mechanism Partial gene loss after polyploidization results in non-doubled gene copy numbers in tetraploids relative to diploids.
- Observation SA biosynthesis genes are highly conserved in protein sequences, protein structures and conserved motifs.
- Observation Cis-element analysis indicated that expression of SA biosynthesis genes is governed by a complex interplay of phytohormones, stress signals and transcription factors.
- Observation Yeast one-hybrid assays confirmed binding of GhWRKY21 to the GhICS2-1 promoter.
- Observation Yeast one-hybrid assays confirmed binding of GhMYB12 to the GhPAL1-2 promoter.
