Alpine plants, according to a recent study, are more at risk from prolonged heatwaves than previously thought, as extended heat exposure lowers the temperature at which critical damage occurs.

Transgenerational effects of heat stress in Arabidopsis thaliana
Heat stress can have transgenerational effects on a plant's offspring but how important are the timing and frequency of these events?

Phenotypic plasticity in response to temperature fluctuations is genetically variable in Arabidopsis thaliana
Climate change will not only mean warmer temperatures but also stronger temperature fluctuations. Phenotypic plasticity could help plants to deal with negative effects of temperature variability and allow them to...
Rye B chromosomes and heat tolerance in microsporogenesis
Rye supernumerary (B) chromosomes possess an accumulation mechanism involving the subtelomeric domain enriched by B chromosome specific DNA sequence families, D1100 and E3900. Pereira et al. show that presence of rye B...

Getting out in the sun can lead to better sex
What could make sex better for a plant? When it brings in new genes from other plants. And this is what happens when faba beans get heat stress.
Role of redox homeostasis in thermo-tolerance (Review)
de Pinto et al. provide an overview of the redox pathways that contribute to how plants cope with heat stress, focussing on the roles of reactive oxygen species (ROS), redox metabolites and enzymes in the signalling...
Thermotolerance in pondweeds
Molecular-based studies of thermotolerance have rarely been performed on wild plants, although this trait can be critical for summer survival. Amano et al. use a chlorophyll bioassay combined with gene-expression...
Free—open access paper: Reductions in biomass accumulation, photosynthesis in situ and the net carbon balance are the costs of protecting Vitis vinifera ‘Semillon’ grapevines from heat stress with shade covering
Shade cloth can be used to protect grapevines from high temperatures. However, the resulting low light intensity is shown to reduce photosynthesis, leading to lower carbon allocation to vegetative growth and sugar...
