Other claims from this paper (10)
- Observation A genome-wide analysis identified 58 WRKY genes (LcWRKYs) in litchi for the first time.
- Observation Phylogenetic analysis classified the LcWRKY proteins into three major groups (I, II and III).
- Observation Group II was markedly expanded, containing 42 members divided into five subgroups.
- Observation LcWRKYs were unevenly distributed across litchi chromosomes, with chromosome 3 showing the highest gene density.
- Mechanism Collinearity analysis suggested that segmental and tandem duplications contributed to the evolutionary expansion of the WRKY family.
- Observation Promoter analysis showed LcWRKYs are enriched with light-, hormone- (e.g., ABA, MeJA, SA) and stress-responsive cis-acting elements.
- Observation Multiple LcWRKYs were significantly up-regulated during the middle and late stages of fruit development.
- Observation qRT-PCR showed pronounced induction of four representative LcWRKY genes at 40 days post-anthesis.
- Mechanism The four representative genes are suggested to be potentially involved in regulating fruit development, particularly mid-development.
- Observation All LcWRKY proteins were predicted to be hydrophilic and nuclear-localized.
