Papers
Callose (β-1,3 glucan) is essential for Arabidopsis pollen wall patterning, but not tube growth
Shuh-ichi Nishikawa,Shuh-ichi Nishikawa,Gregory M Zinkl,Robert Swanson,Daisuke Maruyama,Daphne Preuss +5 more
TL;DR: Three additional cals5 alleles that similarly alter exine patterns, but instead produce fertile pollen are described, demonstrating that a structured exine layer is not required for pollen development, viability or fertility.
Independent Control by Each Female Gamete Prevents the Attraction of Multiple Pollen Tubes
Daisuke Maruyama,Yuki Hamamura,Hidenori Takeuchi,Daichi Susaki,Moe Nishimaki,Daisuke Kurihara,Ryushiro D. Kasahara,Tetsuya Higashiyama +7 more
TL;DR: Intriguingly, second-pollen-tube attraction induced by half-successful fertilization allowed the ovules to complete double fertilization, producing a genetically distinct embryo and endosperm.

Fertilization recovery after defective sperm cell release in Arabidopsis.
Ryushiro D. Kasahara,Daisuke Maruyama,Yuki Hamamura,Takashi Sakakibara,David Twell,Tetsuya Higashiyama +5 more
TL;DR: The results suggest that flowering plants precisely control the number of pollen tubes that arrive at each ovule and employ a fertilization recovery mechanism to maximize the likelihood of successful seed set.

The AMOR Arabinogalactan Sugar Chain Induces Pollen-Tube Competency to Respond to Ovular Guidance
Akane Mizukami,Rie Inatsugi,Jiao Jiao,Toshihisa Kotake,Keiko Kuwata,Kento Ootani,Satohiro Okuda,Subramanian Sankaranarayanan,Yoshikatsu Sato,Daisuke Maruyama,Hiroaki Iwai,Estelle Garénaux,Chihiro Sato,Ken Kitajima,Yoichi Tsumuraya,Hitoshi Mori,Junichiro Yamaguchi,Kenichiro Itami,Narie Sasaki,Tetsuya Higashiyama +19 more
TL;DR: It is suggested that the AMOR sugar chain in the ovary renders the pollen tube competent to the chemotropic response prior to final guidance by LURE peptides.

Dynamic F-actin movement is essential for fertilization in Arabidopsis thaliana
Tomokazu Kawashima,Daisuke Maruyama,Murat Shagirov,Jing Li,Yuki Hamamura,Ramesh Yelagandula,Yusuke Toyama,Frédéric Berger +7 more
TL;DR: This work uses Arabidopsis thaliana to document a novel mechanism that regulates F-actin dynamics in the female gametes and is essential for fertilization, and identifies a female gamete-specific Rho-GTPase that regulating F- actin dynamics and shows that actin–myosin interactions are also involved in male gamete nucleus migration.
