Journal ArticleDOI
Rice Plant Development: from Zygote to Spikelet
Jun-Ichi Itoh,Ken-Ichi Nonomura,Kyoko Ikeda,Shinichiro Yamaki,Yoshiaki Inukai,Hiroshi Yamagishi,Hidemi Kitano,Yasuo Nagato +7 more
TL;DR: The phasic development of the rice plant is described, and the developmental courses of major organs, leaf, root and spikelet, and specific organs/tissues are described to propose a staging system for each organ.
Journal ArticleDOI
A germ cell specific gene of the ARGONAUTE family is essential for the progression of premeiotic mitosis and meiosis during sporogenesis in rice.
Ken-Ichi Nonomura,Ken-Ichi Nonomura,Akane Morohoshi,Mutsuko Nakano,Mitsugu Eiguchi,Akio Miyao,Hirohiko Hirochika,Nori Kurata +7 more
TL;DR: Results indicate that the germ cell–specific rice MEL1 gene regulates the cell division of premeiotic germ cells, the proper modification of meiotic chromosomes, and the faithful progression of meiosis, probably via small RNA–mediated gene silencing, but not the initiation and establishment of germ cells themselves.
Journal ArticleDOI
The MSP1 Gene Is Necessary to Restrict the Number of Cells Entering into Male and Female Sporogenesis and to Initiate Anther Wall Formation in Rice
Ken-Ichi Nonomura,Kazumaru Miyoshi,Mitsugu Eiguchi,Tadzunu Suzuki,Akio Miyao,Hirohiko Hirochika,Nori Kurata,Nori Kurata +7 more
TL;DR: It is suggested that the MSP1 product plays crucial roles in restricting the number of cells entering into male and female sporogenesis and in initiating anther wall formation in rice.
Journal ArticleDOI
Rice germline-specific Argonaute MEL1 protein binds to phasiRNAs generated from more than 700 lincRNAs.
Reina Komiya,Hajime Ohyanagi,Mitsuru Niihama,Toshiaki Watanabe,Mutsuko Nakano,Nori Kurata,Ken-Ichi Nonomura,Ken-Ichi Nonomura +7 more
TL;DR: The evidence is provided that the miR2118-dependent and the DCL4-dependent pathways are both required for biogenesis of 21-nt phasiRNAs associated with germline-specific MEL1 AGO in rice, and over 700 lincRNAs are key factors for induction of this biogenesis during reproductive-specific stages.
Journal ArticleDOI
The novel gene HOMOLOGOUS PAIRING ABERRATION IN RICE MEIOSIS1 of rice encodes a putative coiled-coil protein required for homologous chromosome pairing in meiosis.
Ken-Ichi Nonomura,Mutsuko Nakano,Toshiyuki Fukuda,Toshiyuki Fukuda,Mitsugu Eiguchi,Akio Miyao,Hirohiko Hirochika,Nori Kurata,Nori Kurata +8 more
TL;DR: It is clarified that the PAIR1 protein plays an essential role in establishment of homologous chromosome pairing in rice meiosis.
