Previous study identified Os03g25350 as a member ofthe type VI
nsLTPs family [17], which was named as OsLTPL36 in Rice Genome
Annotation Project (http://rice.plantbiology.msu.edu/). OsLTPL36
was preferentially expressed in developing seed of rice, with a maximum
expression levels in seed of 7 day after pollination (DAP)
[25]. In this study, we examined the expression pattern of OsLTPL36
using transcriptional profiling and in situ hybridization tests. RNAi
was carried out to reduce the expression of OsLTPL36, which led
to defected seed in transgenic plants. FA content was reduced
and grain chalkiness rate was increased in OsLTPL36-RNAi lines
compared to WT. In addition, suppressed expression of OsLTPL36
resulted in delayed embryo development and impeded seed germination.
These results implied that OsLTPL36, a seed specific lipid
transporter, might play an important role in regulating seed quality,
seed development and seed germination in rice.
