Abstract: The present invention provides a promoter for inducing expression specifically in at least one site of roots and stem apices. By using this promoter, it is possible to synthesize a resistance substance against nematodes or soil pathogens in roots; synthesize a substance promoting the development of roots in the roots; produce a gene recombinant plant in which expression of a selective marker in the redifferentiated plant body is limited to roots when the plant is young, so as to suppress the expression when the plant is matured; or the like. Further, the capability of expression in stem apices can be used to develop a technique for suppress gene expression in vigorously proliferating cells.

Abstract: The inventors investigated the impact of an 11-bp deletion in the swine Mx1 gene on the ability to suppress propagation of influenza viruses belonging to the myxovirus family, and revealed that the deletion led to a complete loss of the ability to suppress viral propagation. Through the detection of the 11 -bp deletion, pigs can be examined for their resistance to RNA viruses such as influenza viruses and the virus that causes PRRS.

Abstract: The present inventors successfully isolated a photoperiod sensitivity gene Hd6 from rice by a linkage analysis. It was revealed that the photoperiod sensitivity of plants can be modified by introducing the gene or controlling the expression of the gene. Further, it was demonstrated that the photoperiod sensitivity of plants can be assessed by detecting the presence or absence of the functional gene.

Abstract: An objective of the present invention is to provide polynucleotides encoding insect desiccation resistance proteins, and uses thereof. cDNA libraries were produced from Polypedilum vanderplanki larvae in a desiccated state, a P. vanderplanki EST database was constructed, and genes encoding LEA proteins were isolated. This resulted in the successful isolation of three types of novel gene encoding LEA-like proteins (PvLEA1, PvLEA2, and PvLEA3). When secondary structure predictions and motif searches were performed on the proteins deduced from each of the genes, all three proteins had ?-helix-rich structures and LEA_4 motifs, which are characteristic of LEA proteins. Moerover, the recombinant proteins synthesized from PvLEA1, 2 and 3 genes were heat soluble even when boiling, so that PvLEA1, 2 and 3 proteins have highly hydrophilic property as well as plant LEA proteins. Therefore, the three isolated genes were found to be novel P. vanderplanki-derived LEA genes.
