Abstract:
Two
Aconitum pendulum N. Busch cultivars (‘WSYB1’ and ‘WSYY1’) were used as materials for transcriptome sequencing (RNA-seq) using bioinformatics to identify possible style and pollen
S genes and analyze their sequence characteristics. Results identified two style
S genes (
ApSRNase) specifically or highly expressed in the style and two pollen
S genes (
ApSLF) specifically expressed in pollen. Similar to the sequenced plant
Aquilegia coerulea James, this study showed that there was a S-RNase-based self-incompatibility system controlled by
S-RNase and
SLF in
A. pendulum, but no Papaveraceae-type self-incompatibility system controlled by
sS and
pS.
