Dear Editor, Brassica rapa is an important crop and a model plant for studying Brassica genome evolution and gene function. The silique of B. rapa derived from the gynoecium nor- mally consists of two carpels that are separated by a false septum, and thus has two Iocules （bilocular）. Multilocular （more than two carpels） lines of B. rapa have been discov- ered in nature and are considered advantageous because the multilocular type could potentially increase the seed yield by producing more seeds per silique than the biloc- ular type. However, the molecular basis of the important seed vield-related trait is ooorlv understood.

Tropical cyclones typically form over warm tropical and subtropical ocean surfaces, as their formation and intensification rely primarily on the energy provided by the ocean. Pioneering research by Gray (1968) revealed that the formation of tropical cyclones requires the sea surface temperature (SST) to be no less than 26.5℃. Consequently, SST is commonly recognized as a crucial parameter among the environmental factors influencing tropical cyclone formation(Gray, 1979;Emanuel and Nolan, 2004).
