Ubiquitination-driven proteostasis remodeling underlies oxidative stress and actin degradation in citrus Huanglongbing
Abstract Citrus huanglongbing, caused by Candidatus Liberibacter asiaticus (CLas), is associated with severe metabolic disruption, chronic immune activation, and progressive decline of citrus trees, but the post-translational mechanisms underlying these responses remain poorly understood. Here, we combined ubiquitinated peptide immunoaffinity enrichment with 4D label-free quantitative proteomics…
