Patent number: 8173790Abstract: 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. Moreover, 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.Type: GrantFiled: May 9, 2011Date of Patent: May 8, 2012Assignee: National Institute of Agrobiological SciencesInventors: Takahiro Kikawada, Takashi Okuda, Masahiko Watanabe, Kazuei Mita, Keiko Kadono

Moreover, the recombinant proteins synthesized from these genes were heat soluble even when boiling, so that these proteins have hydrophilic properties as high as plant LEA proteins. Therefore, the three isolated genes were found to be novel P. vanderplanki-derived LEA genes.Type: GrantFiled: November 21, 2008Date of Patent: May 10, 2011Assignee: National Institute of Agrobiological SciencesInventors: Takahiro Kikawada, Takashi Okuda, Masahiko Watanabe, Kazuei Mita, Keiko Kadono
