Some plants can “escape” drought stress by speeding up their life cycles, minimising water loss and allocating more resources to roots when water is available. Over half of the world’s worst weeds are annuals and occur...
Sink-source imbalance could cause accumulation of total non-structural carbohydrates (TNC) and down-regulation of photosynthesis. Sugiura et al. investigate how sink-source imbalance causes photosynthetic down...
Soil acidity and climate change threaten future food production. Dong et al. investigate the effects of free-air CO2 enrichment (550 vs. 400 µmol mol-1) on plant growth and yield of hexaploid wheat lines differing in...
Although many studies have documented the effects of global warming on invasive plants, little is known about whether the effects of warming on plant invasion differ depending on the imposed change in different diurnal...
Deciduous species must rely on stored reserves in stems and roots for the initiation of new season springtime growth. So perhaps evergreen species that can photosynthesize year-round rely more on leaf photosynthate to...
Drought severely limits forage productivity of C4 grasses across the tropics. Napier grass (Pennisetum purpureum) and Brachiaria hybrid cv. Mulato II are tropical C4 grasses used for livestock production due to their...
Biomass allocation patterns are important to ecosystem carbon cycles, and differ among species and in response to nutrient availability. Zhou et al. examine responses of ephemeral and annual plant species to different...
