Unlocking Citrus Resistance: Gene Polymorphisms CVPDr in Bali’s Citrus Plants

Introduction Citrus Vein Phloem Degeneration (CVPD) poses a major threat to citrus cultivation in Indonesia, affecting citrus productivity and quality. Recent research on citrus plants in Bali has uncovered the role of the CVPDr gene in determining resistance to CVPD. Understanding these gene polymorphisms can help develop disease-resistant citrus varieties.

Understanding the CVPDr Gene in Citrus Plants

• CVPD is caused by Candidatus Liberibacter asiaticus, a gram-negative bacterium.
• While most citrus plants are susceptible, certain varieties, such as Seedless Lime (Citrus aurantiifolia var. Seedless) and Kinkit Citrus (Triphacia trifoliate), show natural tolerance.
• The CVPDr gene, linked to disease resistance, has been detected in both susceptible and resistant citrus varieties.

Key Findings from the Study

• PCR testing confirmed that 25 out of 27 citrus plant samples contained CVPDr DNA fragments (841 bp).
• Resistant citrus species such as T. trifoliata and C. aurantifolia var. Seedless grouped phylogenetically with certain citrus varieties like C. nobilis var. Buleleng and C. amblycarpa.
• Some susceptible citrus species also carried the CVPDr gene, suggesting a lack of gene expression rather than complete absence.

The Implications of CVPDr Gene Polymorphisms According to the American Society for Horticultural Science (ASHS), plant genetics play a crucial role in disease resistance. Studying CVPDr polymorphisms could help develop gene-based breeding strategies to enhance citrus resilience against CVPD.
