Growth and Transcriptome Responses of Cunninghamia Lanceolata Seedlings to Light Spectra

Six distinct light quality treatments, including blue, red, and far-red light, were applied to Cunninghamia lanceolata seedlings at a constant photosynthetic photon flux density of 400 μmol·m⁻²·s⁻¹. The dataset contains measurements of stem elongation, root collar diameter, phytohormone levels (GA₃ and ABA), and transcriptomic data for photoreceptor and metabolic pathway genes. Bo Liu published this research on figshare in April 2026.

Use Cases

• Model the relationship between light spectrum treatments and stem elongation or root collar diameter measurements.
• Analyze the antagonistic pattern between gibberellic acid (GA₃) and abscisic acid (ABA) hormone levels under different light conditions.
• Identify differentially expressed genes, such as PHYB, CRY1, CRY2, COP1, PIF3, and HY5, in response to specific light spectra.
• Correlate light treatments with transcriptomic pathway activity for flavonoid biosynthesis, phenylpropanoid metabolism, or carotenoid/stilbenoid metabolism.
• Compare growth and molecular responses across the six light treatments (WL, BL, RL, FrL, 1:1L, 1:2L) to identify optimal spectra for seedling development.

Strengths

• Data covers six controlled experimental light treatments applied at a precise photosynthetic photon flux density of 400 μmol·m⁻²·s⁻¹.
• Includes multi-faceted measurements: morphological growth, phytohormone assays (GA₃, ABA), and transcriptomic analysis of key pathways.
• Published under a permissive CC-BY-4.0 license in April 2026, ensuring recent and reusable data.

Limitations

• The dataset is small, with a total file size of only 666.1 KB, indicating limited scope and likely a low number of experimental replicates or samples.
• Specific sample size (number of seedlings), row count, and column details are unknown, limiting reproducibility and statistical power assessment.
• Data is from a single study on one tree species (Cunninghamia lanceolata), limiting generalizability to other plants.
