Quinoa TCP Gene Family Expression and CqTCP11 Stress Response Analysis

20 non-redundant TCP transcription factor genes were identified genome-wide in the stress-tolerant cereal Chenopodium quinoa. The study, authored by Shanmin Zhou and last updated in June 2026, characterizes gene features, promoter elements, and tissue-specific expression, with functional verification showing CqTCP11 improves seed germination under salt and drought stress. The dataset is a 174.6 KB supplementary document shared under a CC-BY-4.0 license on figshare.

Use Cases

• Identify candidate genes for improving abiotic stress tolerance in quinoa based on the characterization of 20 CqTCP members.
• Study the role of specific cis-acting elements in promoter regions related to hormone and light responses.
• Analyze tissue-specific expression patterns of TCP transcription factors in quinoa.
• Investigate the functional role of CqTCP11 in enhancing antioxidant capacity and osmotic adjustment under stress.

Strengths

• Dataset is derived from a systematic genome-wide characterization of a specific gene family (20 CqTCP members).
• Functional verification of a key gene (CqTCP11) is described, linking genotype to a measurable phenotype (improved germination under stress).
• The promoter analysis identifies specific cis-acting elements related to abiotic stress, hormone, and light responses.

Limitations

• The primary data file is a 174.6 KB DOCX document, which may require extraction or conversion for computational analysis.
• Column-level documentation and sample data are unavailable, making field semantics and structure uncertain.
• Row count is unknown, which may limit suitability assessment for large-scale analyses.
