The structure-activity relationship of aryloxyacetylthioureas for the inhibition of Orobanche minor radicle elongation.
Okazawa A, Noda S, Mimura Y, Fujino K, Wakabayashi T, Ohta D, Sugimoto Y, Sonoda M. Okazawa A, et al. J Pestic Sci. 2023 Nov 20;48(4):149-155. doi: 10.1584/jpestics.D23-034. J Pestic Sci. 2023. PMID: 38090214 Free PMC article.
Planteose accumulates as a storage carbohydrate in the dry seeds of root parasitic weeds. In Orobanche minor seeds, planteose is hydrolyzed by an alpha-galactosidase, OmAGAL2, during germination. It was found that the OmAGAL2 inhibitor, PI-28, suppressed the radicle …

Okazawa A, Wakabayashi T, Muranaka T, Sugimoto Y, Ohta D. Okazawa A, et al. J Pestic Sci. 2020 Nov 20;45(4):230-237. doi: 10.1584/jpestics.D20-057. J Pestic Sci. 2020. PMID: 33304192 Free PMC article.
Previously, metabolomic analyses were conducted on germinating seeds of a broomrape, Orobanche minor, to find novel targets for its selective control. Interestingly, planteose metabolism was identified as a possible target, and nojirimycin (NJ) selectively inhibited …

Involvement of alpha-galactosidase OmAGAL2 in planteose hydrolysis during seed germination of Orobanche minor.
Okazawa A, Baba A, Okano H, Tokunaga T, Nakaue T, Ogawa T, Shimma S, Sugimoto Y, Ohta D. Okazawa A, et al. J Exp Bot. 2022 Apr 5;73(7):1992-2004. doi: 10.1093/jxb/erab527. J Exp Bot. 2022. PMID: 34850875 Free PMC article.
In our previous study, planteose metabolism was revealed to be activated soon after the perception of strigolactones in germinating seeds of O. minor. Nojirimycin inhibited planteose metabolism and impeded seed germination of O. minor, indicating a possible target f …

Structure Elucidation and Biosynthesis of Orobanchol.
Wakabayashi T, Ueno K, Sugimoto Y. Wakabayashi T, et al. Front Plant Sci. 2022 Feb 9;13:835160. doi: 10.3389/fpls.2022.835160. eCollection 2022. Front Plant Sci. 2022. PMID: 35222492 Free PMC article. Review.
Strigolactones (SLs), a class of phytohormones that regulate diverse developmental processes, were initially characterized as host-derived germination stimulants for seeds belonging to the genera Striga, Orobanche, and Phelipanche. Orobanchol (1), which is detected in the …

Tryptophan derivatives regulate the seed germination and radicle growth of a root parasitic plant, Orobanche minor.
Kuruma M, Suzuki T, Seto Y. Kuruma M, et al. Bioorg Med Chem Lett. 2021 Jul 1;43:128085. doi: 10.1016/j.bmcl.2021.128085. Epub 2021 May 6. Bioorg Med Chem Lett. 2021. PMID: 33964445
We found that a major microbial culture broth component, tryptone, inhibits the SL-inducible germination of a root parasitic plant, Orobanche minor. l-tryptophan (l-Trp) was isolated as the active compound from tryptone. We further found that l-Trp related compounds …

Cycloheximide in the nanomolar range inhibits seed germination of Orobanche minor.
Nogami R, Nagata M, Imada R, Kai K, Kawaguchi T, Tani S. Nogami R, et al. J Pestic Sci. 2024 Feb 20;49(1):22-30. doi: 10.1584/jpestics.D23-038. J Pestic Sci. 2024. PMID: 38450089 Free PMC article.
From the 992 samples of culture extracts of microorganisms isolated from soil in Japan, we found that the extract of Streptomyces sp. no. 226 inhibited Orobanche minor seed germination without significantly affecting the seed germination of Trifolium pratense and th …

Germination stimulatory activity of bacterial butenolide hormones from Streptomyces albus J1074 on seeds of the root parasitic weed Orobanche minor.
Okazawa A, Samejima H, Kitani S, Sugimoto Y, Ohta D. Okazawa A, et al. J Pestic Sci. 2021 May 20;46(2):242-247. doi: 10.1584/jpestics.D21-014. J Pestic Sci. 2021. PMID: 34135687 Free PMC article.
These butenolides were found to specifically induce seed germination of Orobanche minor. Our findings contribute to understanding the molecular mechanisms of germination stimulant perception and to the development of a method for their biological control....

A Divergent Clade KAI2 Protein in the Root Parasitic Plant Orobanche minor Is a Highly Sensitive Strigolactone Receptor and Is Involved in the Perception of Sesquiterpene Lactones.
Takei S, Uchiyama Y, Bürger M, Suzuki T, Okabe S, Chory J, Seto Y. Takei S, et al. Plant Cell Physiol. 2023 Sep 15;64(9):996-1007. doi: 10.1093/pcp/pcad026. Plant Cell Physiol. 2023. PMID: 37061839 Free PMC article.
The S. hermonthica SL receptors are included in this specific clade, which is called KAI2 divergent (KAI2d). Orobanche minor is an obligate root holoparasitic plant that grows completely dependent on the host for water and nutrients because of a lack of photosynthet …
