Weighing the options: a test of alternative stomatal optimisation models at high temperatures

New Phytologist, Volume 250, Issue 3, Page 1551-1568, May 2026.
Summary Stomatal optimisation models centre upon a fundamental tradeoff for plants: opening stomata promotes carbon uptake, but closing stomata prevents water loss. However, stomatal opening can occur at high temperatures, causing evaporative cooling which limits thermal damage to leaves.

The sclerophyllous Eucalyptus camaldulensis and herbaceous Nicotiana tabacum have different mechanisms to maintain high rates of photosynthesis

Frontiers in Plant Science, 2016
It is believed that high levels of mesophyll conductance (gm) largely contribute to the high rates of photosynthesis in herbaceous C3 plants. However, some sclerophyllous C3 plants that display low levels of gm have high rates of photosynthesis, and the ...

Arabidopsis acclimation to daily environmental fluctuations converts a defense response regulator into a susceptibility factor toward Sclerotinia

New Phytologist, Volume 250, Issue 4, Page 2516-2534, May 2026.
Summary Acclimation enables plants to adjust to immediate environmental fluctuations and is therefore key to the resilience of plant disease resistance in a time of climate change. Here, we report on the acclimation of Arabidopsis thaliana quantitative immune responses against the fungal pathogen Sclerotinia sclerotiorum to daily environmental ...

Photosynthesis and photosynthetic electron flow in the alpine evergreen species Quercus guyavifolia in winter

Frontiers in Plant Science, 2016
Alpine evergreen broadleaf tree species must regularly cope with low night temperatures in winter. However, the effects of low night temperatures on photosynthesis in alpine evergreen broadleaf tree species are unclear.

Plant Peroxisomes: Biogenesis and Function [PDF]

, 2012
Peroxisomes are eukaryotic organelles that are highly dynamic both in morphology and metabolism. Plant peroxisomes are involved in numerous processes, including primary and secondary metabolism, development, and responses to abiotic and biotic stresses ...

OsMT2b Regulates Pollen Development and ROS Homeostasis in a Photoperiod‐Dependent Manner

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3051-3064, May 2026.
ABSTRACT Reactive oxygen species (ROS) are signalling molecules that promote programmed cell death in animal and plant systems. However, their role in rice (Oryza sativa L.) anther development is unclear. In this study, we show that lower transcript levels of the metallothionein gene OsMT2b in japonica rice plants obtained by RNA interference (RNAi ...

The C2H2‐GGAT Regulatory Module Fine‐Tunes Glutamate Homeostasis to Improve Fruit Flavour and Enhance Disease Resistance in Peach

Plant Biotechnology Journal, Volume 24, Issue 5, Page 3282-3295, May 2026.
ABSTRACT Free amino acids (FAAs) play a fundamental role in determining fruit quality and stress adaptation, yet their genetic regulation remains poorly understood. Through an integrated approach combining metabolomic and sensory analyses of 120 peach (Prunus persica) hybrids, we identified glutamate as a key metabolite linking FAA content to umami ...

Investigating exudate- and habitat-mediated effects of phytoplankton on lake bacterial community dynamics [PDF]

Correlated patterns of abundance, activity, and composition are commonly observed between phytoplankton and bacterial communities. There are a number of potential explanations for correlated dynamics.
