Citrus HLB Resistance Interstock Greenhouse Experiment Data

Greenhouse experiment data assesses six HLB-resistant genotypes as interstocks between susceptible sweet orange scion and Rangpur lime rootstock. The study investigates CLas infection and titer in leaves, stem bark, and roots over 12–24 months, alongside molecular, anatomical, and biometric variables. Data includes measurements from CLas-inoculated and non-inoculated control plants.

Use Cases

• Analyze CLas titer levels in scion, interstock bark, and rootstock tissues to compare bacterial movement blockage across different hybrid genotypes.
• Correlate dry weight of the root system with CLas + CTV infection status to quantify disease impact on plant biomass.
• Investigate changes in sieve phloem anatomy and gene expression data associated with dual CLas and CTV infection.
• Evaluate the percentage of composite plants where CLas movement from scion to roots was blocked using specific hybrid interstocks like F1 hybrid of C. australis × C. inodora.

Strengths

• Data originates from a controlled greenhouse experiment with both inoculated and non-inoculated control plants for comparison.
• Study assesses multiple variables: CLas infection/titer, molecular data, anatomical features, and biometric measurements like dry weight.
• Temporal coverage spans 12 to 24 months post-inoculation, allowing observation of disease progression.

Limitations

• Dataset is small in scale at 233.6 KB, indicating limited sample size or number of observations.
• Findings are from greenhouse conditions; applicability to long-term field performance requires further evaluation.
• Specific row and column counts are unknown, limiting assessment of dataset structure and volume.
