| transcriptional response of susceptible and tolerant citrus to infection with candidatus liberibacter asiaticus. | candidatus liberibacter asiaticus (las), a non-culturable phloem-limited bacterium, is the suspected causal agent of huanglongbing (hlb) in florida. hlb is one of the most devastating diseases of citrus and no resistant cultivars have been identified to date, though tolerance has been observed in the genus poncirus and some of its hybrids. this study compares transcriptional changes in tolerant us-897 (citrus reticulata blanco×poncirus trifoliata l. raf.) and susceptible 'cleopatra' mandarin (c. ... | 2011 | 22325873 |
