Rice phytochrome-interacting factor-like protein OsPIL1 functions as a key regulator of internode elongation and induces a morphological response to drought stress
Daisuke Todaka,Kazuo Nakashima,Kyonoshin Maruyama,Satoshi Kidokoro,Yuriko Osakabe,Yusuke Ito,Satoko Matsukura,Yasunari Fujita,Kyouko Yoshiwara,Masaru Ohme-Takagi,Mikiko Kojima,Hitoshi Sakakibara,Kazuo Shinozaki,Kazuko Yamaguchi-Shinozaki +13 more
TL;DR: OsPIL1 functions as a key regulatory factor of reduced plant height via cell wall-related genes in response to drought stress, and this regulatory system may be important for morphological stress adaptation in rice under drought conditions.

Ligand-binding properties and subcellular localization of maize cytokinin receptors
TL;DR: Aqueous two-phase partitioning and sucrose density-gradient centrifugation followed by immunological detection with monoclonal antibody showed that ZmHK1 was associated with the endoplasmic reticulum (ER), which strongly suggest that at least a part of cytokinin perception occurs in the ER.

Molecular cloning and characterization of complementary DNA encoding for ferredoxin-dependent glutamate synthase in maize leaf.
TL;DR: Analysis of genomic DNA indicates the presence of a single-copy gene for ferredoxin glutamate synthase in maize and contains a short region similar to a potential FMN-binding region of yeast flavocytochrome b2.

Excessive ammonium assimilation by plastidic glutamine synthetase causes ammonium toxicity in Arabidopsis thaliana.
Takushi Hachiya,Jun Inaba,Mayumi Wakazaki,Mayuko Sato,Kiminori Toyooka,Atsuko Miyagi,Maki Kawai-Yamada,Daisuke Sugiura,Tsuyoshi Nakagawa,Takatoshi Kiba,Alain Gojon,Hitoshi Sakakibara +11 more
TL;DR: In this article, it was shown that ammonium assimilation by GLUTAMINE SYNTHETASE 2 (GLN2) localized in the plastid rather than ammonium accumulation is a primary cause for toxicity, which challenges the textbook knowledge.
