Conference: Parasitic Flowering Plants in Forests

Mistletoes

Dear members of the IPPS, In addition to our conference in Kenya this summer, the International Union of Forest Research Organizations (https://www.iufro.org/) is organizing a parasitic plant session during the 2022 meeting of its Forest Health, Pathology and Entomology work group. The conference will take place in Lisbon, Portugal, from 6 to 9 September 2022 […]

A host-free transcriptome for haustoriogenesis in Cuscuta campestris: signature gene expression identifies markers of successive development stages

FI-12d54fbb

The development of the infection organ of the parasitic angiosperm genus Cuscuta is a dynamic process that is normally obscured from view as it happens endophytically in its host. We artificially induced haustoriogenesis in C. campestris by far-red light to define specific morphologically different stages and analyze their transcriptional patterns. This information enabled us to extract sets of high-confidence […]

Localization of storage carbohydrate planteose and identification of the planteose hydrolytic enzyme OmAGAL2 in seeds of Orobanche minor

MSimaging-3185c8bb

Using MALDI-MS imaging, we visualized the localization of trisaccharide planteose in the dry seeds of Orobanche minor. Planteose was revealed to accumulate outside of the embryo, which supported the role of planteose as a storage carbohydrate. Since the first step of planteose is the hydrolysis of α-galactosyl linkage, we surveyed α-galactosidases in our transcriptome data. Among the […]

Integrated small RNA, mRNA, and degradome sequencing reveals the important role of miRNAs in the interactions between parasitic plant Cuscuta australis and its host Trifolium repens

1-8d112ec1

Cuscuta australis R.Br. is a stem parasite that obtains water and nutrients from host plants, with which it also exchanges proteins and mRNAs with host plants. Recently, a study found that novel miRNAs accumulated during C. campestris Yunk. parasitism of Arabidopsis thaliana L. However, the fate of miRNAs transferred from parasite to host plants as well as their […]
