In rice genome, 53 nsLTPL genes were annotated [21]. Based on the expression pattern of nsLTPs, they were divided into two main groups. The first group has more general expression patterns and/or functions, whereas the second group has acquired more specific expression patterns and/or functions and could play key roles in specific pathways [17]. So far, a few nsLTPs of rice have been identified. OsDIL over-expressing transgenic rice plants were more tolerant to drought stress during vegetative development and showed less severe tapetal defects and fewer defective anther sacs when treated with drought at the reproductive stage [22]. OsLTP6 was anther specific expressed through a combination of positive and negative regulatory elements in the promoter region [23]. OsC6, encoding a lipid transfer protein, playsa crucial role in the development of lipidic or bicules and pollen exine during anther development in rice [24]. However, the function of nsLTPs specifically expressed in rice seed has not been reported.
