Specialisation within the DWARF14 protein family confers distinct responses to karrikins and strigolactones in Arabidopsis
The results support the existence of an endogenous, butenolide-based signalling mechanism that is distinct from the strigolactone pathway, providing a molecular basis for the adaptive response of plants to smoke.
Climate change and plant regeneration from seed
Increased research in understudied ecosystems, on key issues related to seed ecology, and on evolution of seed traits in nonweedy species is needed to more fully comprehend and plan for plant responses to global warming.
Acetyl salicylic acid (Aspirin) and salicylic acid induce multiple stress tolerance in bean and tomato plants
The fact that seedimbibition with SA or ASA confers stress tolerance in plants is more consistent with a signaling role of these molecules, leading to the expression oftolerance rather than a direct effect.

Terrestrial orchid conservation in the age of extinction.
In response to threats to orchid species, integrated conservation approaches have been adopted (including ex situ and translocation principles) in the South West Australian Floristic Region with the result that a significant, multidisciplinary approach is under development to facilitate conservation of some of the most threatened taxa.
The promotive effect of smoke derived from burnt native vegetation on seed germination of Western Australian plants
Exposure of dormant seed to cold smoke derived from burnt native vegetation had a positive influence on germination in one or more seed provenances in 45 out of 94 species of native Western…
Strigolactone Hormones and Their Stereoisomers Signal through Two Related Receptor Proteins to Induce Different Physiological Responses in Arabidopsis1[W]
The results support the conclusion that KAI2-dependent signaling does not respond to canonical SLs and the use of specific stereoisomers might provide valuable information about the specific perception systems operating in different plant tissues, parasitic weed seeds, and arbuscular mycorrhizae.
A Compound from Smoke That Promotes Seed Germination
It is shown that butenolide 3-methyl-2H-furo[2,3-c]pyran-2-one promotes germination of a number of plant species at a level similar to that observed with plant-derived smoke water.
F-box protein MAX2 has dual roles in karrikin and strigolactone signaling in Arabidopsis thaliana

Karrikin signaling requires the F-box protein MAX2, which also mediates responses to the structurally-related strigolactone family of phytohormones, and it is shown that plants can distinguish between these signals.
