Investigating citrus greening disease with PhytoAB antibodies

How does huanglongbing reshape protein stability in citrus?

In Plant Physiology, Li and colleagues linked Candidatus Liberibacter asiaticus infection to widespread changes in protein ubiquitination, weakened antioxidant defenses, and actin degradation. Stabilizing CsACT7 reduced bacterial accumulation in citrus hairy roots—providing a direction for further research.

PhytoAB antibodies used in the study:

• PHY3044A: CAT2 antibody — Used in catalase immunoblotting and immunoprecipitation analyses, helping researchers investigate catalase abundance and ubiquitination.

• PHY3246A: RPT2a/b antibody — Used for CsRPT2B immunoprecipitation and immunoblot analyses investigating proteasome remodeling.

Explore PhytoAB antibodies for your research into plant redox biology, protein turnover, and host–pathogen interactions.
