Table 2_Integrated physiological and molecular insights into photosynthetic responses of m

Ruijia Ma's dataset contains physiological and molecular measurements from a field experiment comparing maize relay-cropped with tobacco to maize monoculture. Data includes photosynthetic indices, chlorophyll content, enzyme activities, and transcriptome sequencing results from maize functional leaves collected at 15, 25, and 35 days after the formation of the intercropping competitive system. The dataset was last updated on May 7, 2026.

Use Cases

• Modeling the impact of shading on crop yield based on photosynthetic parameter reductions.
• Identifying key genes involved in C3 and C4 photosynthetic pathways based on the downregulation of PPC, PPDK, RBCL, and PRK.
• Optimizing relay-cropping schedules based on the analysis of suitable symbiotic periods (0-25 days).

Strengths

• Dataset integrates physiological measurements (photosynthetic indices, chlorophyll, enzyme activities) with molecular data (transcriptome sequencing of 3200 differentially expressed genes).
• Experimental design includes a controlled comparison between relay-cropped and monoculture maize across three time points (15, 25, 35 days).
• Specific maize (Huidan No. 4) and tobacco (K326) cultivars are named, and key downregulated genes are identified.

Limitations

• Dataset is very small (16.9 KB), suggesting it may be a summary table or document rather than raw experimental data.
• Column-level documentation is absent; field semantics must be inferred from the description.
• Row count is unknown, which may limit suitability assessment for large-scale analysis.
