Abstract
Background: Plant root-knot nematode (RKN) disease is a serious threat to agricultural production across the
world.
Meloidogyne incognita is the most prominent pathogen to the vegetables and cash crops cultivated.
Arachis
hypogaea can effectively inhibit
M. incognita, but the underlying defense mechanism is still unclear.
Methods: In our
study, the chemotaxis and infestation of the second-stage juveniles (J2s) of
M. incognita to
A. hypogaea root tips were
observed by the Pluronic F-127 system and stained with sodium hypochlorite acid fuchsin, respectively. The
transcriptome data of
A. hypogaea roots with non-infected or infected by J2s were analyzed.
Results: The J2s could
approach and infect inside of
A. hypogaea root tips, and the chemotactic migration rate and infestation rate were
20.72% and 22.50%, respectively. Differential gene expression and pathway enrichment analyses revealed ubiquinone
and other terpenoid-quinone biosynthesis pathway, plant hormone signal transduction pathway, and phenylpropanoid
biosynthesis pathway in
A. hypogaea roots responded to the infestation of
M. incognita. Furthermore, the
AhHPT
gene, encoding homogentisate phytyltransferase, was considered to be an ideal candidate gene due to its higher
expression based on the transcriptome data and quantitative real-time PCR analysis.
Conclusion: Therefore, the key
gene
AhHPT might be involved in the
A. hypogaea against
M. incognita. These findings lay a foundation for revealing
the molecular mechanism of
A. hypogaea resistance to
M. incognita and also provide a prerequisite for further gene
function verification, aiming at RKN-resistant molecular breeding.
