Transcriptomic and biochemical analysis of pummelo x finger lime hybrids in response to Huanglongbing (HLB).

ABSTRACT:

Background

Huanglongbing (HLB) is a devastating bacterial disease caused by the bacterium Candidatus Liberibacter asiaticus (CaLas) that affects the citrus industry worldwide. This study investigated the response of two pummelo x finger lime hybrid siblings to natural infection with CaLas. The hybrids were identified primarily using leaf morphology and molecular marker assessments and were selected for further studies on the basis of the CaLas titers in leaf petioles.

Results

HLB-infected budwood from the selected hybrids (PFL 2-61 and PFL 1-11), as well as the two parental plants, were propagated by grafting onto Swingle citrumelo rootstocks for further evaluation. Plant samples were collected two years after grafting for analysis. Leaves of PFL2-61 exhibited decreased CaLa
