Subtilase activity in the intrusive cells mediates haustorium maturation in parasitic plants [PDF]

Plant Physiology, 2020
ABSTRACT Parasitic plants that infect crops are devastating to agriculture throughout the world. They develop a unique inducible organ called the haustorium, which connects the vascular systems of the parasite and host to establish a flow of water and nutrients.

Embryo sac haustorium in Dryas octopetala L. (Rosaceae) [PDF]

, 2014
The embryo sac haustorium found in Dryas octopetala L. from the Tatra Mts is the first record of its occurrence in Rosaceae. At the eight-nucleate stage of the embryo sac, the antipodal end of the central cell began to grow into a narrow caecum filled ...

Soil‐dependent variation in strigolactone signaling distance revealed by a parasitic seed germination bioassay

Pest Management Science, EarlyView.
A parasitic seed germination bioassay reveals strong soil‐dependent variation in strigolactone signaling distance, controlled by physical and biological soil properties, which shapes signaling range and parasitic weed infection risk. Abstract BACKGROUND Strigolactones are root‐exuded plant metabolites acting as germination stimulants for several ...

Phloem-Conducting Cells in Haustoria of the Root-Parasitic Plant Phelipanche aegyptiaca Retain Nuclei and Are Not Mature Sieve Elements

Plants, 2017
Phelipanche aegyptiaca parasitizes a wide range of plants, including important crops, and causes serious damage to their production. P. aegyptiaca develops a specialized intrusive organ called a haustorium that establishes connections to the host’s xylem

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

Pest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Overview of the functional virulent genome of the coffee leaf rust pathogen Hemileia vastatrix with an emphasis on early stages of infection

Frontiers in Plant Science, 2014
Hemileia vastatrix is the causal agent of coffee leaf rust, the most important disease of coffee (Coffea arabica). In this work, a 454-pyrosequencing transcriptome analysis of H.

The TaRNS4–TaPP2C10 module regulates wheat resistance to stripe rust through RNA degradation and MAPK cascades

Journal of Integrative Plant Biology, EarlyView.
In wheat, phosphorylation of the S‐like RNase TaRNS4 mediated by the kinase TaRLK5 promotes its degradation of Puccinia striiformis f. sp. tritici RNA in the apoplast, enhancing resistance to stripe rust. TaRNS4 can hijack phosphatase TaPP2C10 to relieve its dephosphorylation of TaMAPK6, thereby activating MAPK‐mediated immune responses. ABSTRACT RNase
