Other claims from this paper (14)
- Observation The study identified 410 GATA genes across seven sequenced Ipomoea species.
- Observation Sweetpotato had 158 GATA genes.
- Observation I. trifida had 54 GATA genes.
- Observation I. triloba had 62 GATA genes.
- Observation I. nil had 39 GATA genes.
- Observation I. purpurea had 32 GATA genes.
- Observation I. cairica had 32 GATA genes.
- Observation I. aquatica had 33 GATA genes.
- Observation GATA genes clustered into four subfamilies (I-IV).
- Mechanism Tandem duplications primarily drove GATA gene expansion in I. triloba, I. trifida and I. nil.
- Mechanism Segmental duplications were predominant in GATA gene expansion in sweetpotato and I. cairica.
- Observation Under salt, drought, Ceratocystis fimbriata and Ditylenchus destructor stresses, 29-60 GATA genes were differentially expressed.
- Method / resource Three representative DEGs (IbGATA33, IbGATA38 and IbGATA126) were validated by qRT-PCR, and results corroborated the transcriptome data.
- Observation Promoter analysis identified multiple stress-responsive cis-regulatory elements in the GATA gene promoters.
