Parasitic flowering plant collections embody the extended specimen
Methods in Ecology and Evolution, 2023 The widespread digitization of natural history collections, combined with novel tools and approaches is revolutionizing biodiversity science. The ‘extended specimen’ concept advocates a more holistic approach in which a specimen is framed as a diverse ...

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.

PLANTS, PEOPLE, PLANET, EarlyView.Parasitic weeds of the family Orobanchaceae are among the most damaging constraints on food production in the tropics, draining water and nutrients from their hosts and threatening the livelihoods of millions of smallholder farmers. Yellow witchweed (Alectra vogelii) can destroy entire legume harvests across sub‐Saharan Africa, where these crops are a ...

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 ...

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 ...

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

Abscisic acid and the antioxidant system are involved in germination of Butia capitata seeds
Acta Botânica Brasílica, 2018 Seed germination is an important step for plants without vegetative propagation and is a physiological process that begins with specific environmental cues resulting in biochemical responses. Breaking-dormancy is necessary to study germination in dormant
