The endophyte’s endophytes of Rafflesia speciosa: A new article on the brief insight on how microbes affecting parasitism of the giant parasitic flower

Hypothetical-microbiome-changes-upon-Rafflesia-infection-of-the-Tetrastigma-host-During_W640

Rafflesia is an endangered endophytic holoparasitic plant that lives the majority of its life inside the tissues of its sole plant host, Tetrastigma. Rafflesia floral buds emerge to produce the world’s largest single flower. Like other plants, holoparasites harbor a diverse microbiome, the role(s) of which has remained largely unstudied. Some of it might involve […]

Cuscuta campestris fine-tunes gene expression during haustoriogenesis as an adaptation to different hosts

Screenshot 2024-01-22 at 17.54.50

https://doi.org/10.1093/plphys/kiad505 In this paper we show that Cuscuta can parry the changes in host cell wall composition that it triggered during its infection and that different host species are met with different strategies of gene expression fine-tuning. The same can be triggered by offering isolated cell wall polysaccharides in a host-free system (without a live […]

Extracellular Self- and Non-Self DNA Involved in Damage Recognition in the Mistletoe Parasitism of Mesquite Trees

Figure_7

In this study, we analyzed the stress responses to the exogenous application of self exDNA and nonself exDNA from the mistletoe P. calyculatus as a source of DAMPs in mesquite trees (P. laevigata). Mesquite trees perceive self- and non-self exDNA with the synthesis of ROS-enzymes system, MAPKs activation and spatial concentrations of phytohormones.  https://www.mdpi.com/1422-0067/25/1/457 […]

New paper: “Fertilization benefits the facultative parasitic plant Rhamphicarpa fistulosa while gains by the infected host Oryza sativa are marginalized”

Fertilization benefits the facultative parasitic plant Rhamphicarpa fistulosa while gains by the infected host Oryza sativa are marginalized

In this study, a collaboration between Natural Resources Institute & Wageningen University & Research – Centre for Crop Systems Analysis, we demonstrate that the facultative parasitic weed Rhamphicarpa fistulosa benefits from fertiliser application (but only) when it parasitises on a host, both in terms of biomass and in terms of reproductive output (seeds). This contrasts […]

(MINI REVIEW) CRISPR gene editing to improve crop resistance to parasitic plants

fgeed-05-1289416-g002

Parasitic plants pose a significant threat to global agriculture, causing substantial crop losses and hampering food security. In recent years, CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) gene-editing technology has emerged as a promising tool for developing resistance against various plant pathogens. Its application in combating parasitic plants, however, remains largely unexplored. This review aims […]

Resistance against broomrapes (Orobanche and Phelipanche spp.) in vegetables: a comprehensive view on classical and innovative breeding efforts

fig. 1

Broomrapes (Orobanche and Phelipanche spp.) are root holoparasites deriving their nourishment from the parasitic interaction they establish with the host plant. Vegetable crops are severely affected worldwide from broomrapes infestations, which are hard-to-manage through the conventional agronomical practices and determines relevant production losses. The identification of resistant varieties represents the ideal solution to face with this noxious threat, […]

Publication: Large-scale interplant exchange of macromolecules between soybean and dodder under nutrient stresses

D40622F53C81764B7C9A6133D5A4934A

Dodder, a parasitic plant, obtains nutrients from its host through haustoria. The exchange of macromolecules between dodder and its host in nutrient-deficient environments is not well understood. In this study, it is shown that, when being subjected to nitrogen or phosphorus deficiency, at the transcript level soybean plants responded more strongly than did dodder plants. However, both plants exhibited significant changes […]
