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 […]

A parasite indirectly affects nutrient distribution by common mycorrhizal networks between host and neighboring plants

1-3493de5c

Cascading effects are ubiquitous in nature and can modify ecological processes. Most plants have mutualistic associations with mycorrhizal fungi, and can be connected to neighboring plants through common mycorrhizal networks (CMNs). However, little is known about how the distribution of nutrients by CMNs to the interconnected plants is affected by higher trophic levels, such as […]

Image analysis for the automatic phenotyping of Orobanche cumana tubercles on sunflower roots.

image-note-ipps-nov21-4946a0c3

Our study proposes a rapid, accurate and low-cost phenotyping tool for the sunflower/O. cumana interaction under controlled conditions through image analysis for broomrape tubercle analysis at early stages of the interaction. We optimized the phenotyping of sunflower/O. cumana interactions by using rhizotrons (transparent Plexiglas boxes) in a growth chamber to control culture conditions and Orobanche inoculum. […]

The role of strigolactones in P deficiency induced transcriptional changes in tomato roots

Fig 1 BMC-7195785c

Background: Phosphorus (P) is an essential macronutrient for plant growth and development. Upon P shortage, plant responds with massive reprogramming of transcription, the Phosphate Starvation Response (PSR). In parallel, the production of strigolactones (SLs)—a class of plant hormones that regulates plant development and rhizosphere signaling molecules—increases. It is unclear, however, what the functional link is […]
