Comparative Physiology of Phytoplasma-Infected Apple, Peach, and Pear Trees

Apple, peach, and pear trees infected by related phytoplasmas from the 16SrX group exhibit starkly different survival outcomes, from decades to weeks. This dataset compares morphological changes in the vascular system and physiological shifts in phloem sap and leaf phytohormones across these three host-pathogen combinations. Findings suggest long-lasting vascular adaptations and altered sap flow in apple trees may underpin their tolerance, unlike the fatal responses in peach and pear.

Use Cases

• Comparing disease progression timelines based on host species and physiological measurements.
• Analyzing correlations between vascular morphology changes and phloem mass flow characteristics.
• Investigating the role of defense- and stress-related phytohormones in plant tolerance mechanisms.
• Modeling host-specific survival outcomes from integrated morphological and physiological data.

Strengths

• Data is derived from a controlled comparative study of three economically important fruit tree species.
• Analysis includes multiple physiological dimensions: vascular morphology, phloem sap chemistry, and phytohormone levels.

Limitations

• Critical metadata is missing: row count, column names, and specific measurement variables are unknown.
• The dataset's recency and update status are not provided.
• The exact sample size and replication details for each tree species are not stated.
