Elakhdar A, El-Naggar A, Kubo T, Kumamaru T
Physiol Plant . 2023 Dec; 175(6):e14089. PMID: 38148212
Drought is a major abiotic stress that impairs the physiology and development of plants, ultimately leading to crop yield losses. Drought tolerance is a complex quantitative trait influenced by multiple...

Kubo T, Yamagata Y, Matsusaka H, Toyoda A, Sato Y, Kumamaru T
Rice (N Y) . 2022 Jul; 15(1):38. PMID: 35841399
Although targeted genome editing technology has become a powerful reverse genetic approach for accelerating functional genomics, conventional mutant libraries induced by chemical mutagens remain valuable for plant studies. Plants containing...

Nosaka-Takahashi M, Kato M, Kumamaru T, Sato Y
PLoS One . 2022 Jun; 17(6):e0269374. PMID: 35657937
The shoot apical meristem (SAM) is composed of a population of stem cells giving rise to the aboveground parts of plants. It maintains itself by controlling the balance of cell...

Hori K, Okunishi T, Nakamura K, Iijima K, Hagimoto M, Hayakawa K, et al.
Rice (N Y) . 2022 Mar; 15(1):13. PMID: 35247122
Phenotypic differences among breeding lines that introduce the same superior gene allele can be a barrier to effective development of cultivars with desirable traits in some crop species. For example,...

Nagamatsu S, Wada T, Matsushima R, Fujita N, Miura S, Crofts N, et al.
Plant Mol Biol . 2022 Jan; 108(4-5):497-512. PMID: 35083581
Mutation of the BEIIb gene in an isa1 mutant background mitigates the negative effect of the ISA1 mutation on grain filling, and facilitates recovery of amyloplast formation in rice endosperm....

Sato Y, Tsuda K, Yamagata Y, Matsusaka H, Kajiya-Kanegae H, Yoshida Y, et al.
Breed Sci . 2021 Nov; 71(3):291-298. PMID: 34776736
Biological resources are the basic infrastructure of bioscience research. Rice ( L.) is a good experimental model for research in cereal crops and monocots and includes important genetic materials used...

Matsusaka H, Fukuda M, Elakhdar A, Kumamaru T
Plant Sci . 2021 Oct; 312:111049. PMID: 34620446
The low level of cysteine-rich proteins (lcrp) mutation indicates a decrease in cysteine-rich (CysR) prolamines, α-globulin, and glutelin. To identify the causing factor of lcrp mutation, to elucidate its function,...

Yuan X, Minobe Y, Tanaka Y, Fukuda Y, Furukawa Y, Miyago M, et al.
J Sci Food Agric . 2021 May; 101(15):6417-6423. PMID: 33982308
Background: Rice α-globulin has been reported to have serum cholesterol-lowering activity in rats. However, it is still unclear whether α-globulin exerts this effect when taken as one of the dietary...

Tian L, Doroshenk K, Zhang L, Fukuda M, Washida H, Kumamaru T, et al.
Plant Cell . 2020 May; 32(8):2566-2581. PMID: 32471860
In rice () endosperm cells, mRNAs encoding glutelin and prolamine are translated on distinct cortical-endoplasmic reticulum (ER) subdomains (the cisternal-ER and protein body-ER), a process that facilitates targeting of their...
