Life on land exposes plants to varied abiotic and biotic environmental stresses. These
environmental drivers contributed to a large expansion of metabolic capabilities during land …

Deciduous trees exhibit a spectacular phenomenon of autumn senescence driven by the
seasonality of their growth environment, yet there is no consensus which external or internal …

Plant growth and development depend on the availability of carbohydrates synthesised in
photosynthesis (source activity) and utilisation of these carbohydrates for growth (sink …

Chlorophyll is responsible for absorbing light which is required to convert solar energy into
chemical energy during photosynthesis. Despite remarkable progresses achieved in …

Plant growth is related to the amount of nutrients that it can acquire and it can be limited by
poor root development and nutrient uptake, and low efficiency of nutrient use. Nutrients are …

Source-to-sink carbon (C) allocation driven by the sink strength, ie, the ability of a sink organ
to import C, plays a central role in tissue growth and biomass productivity. However …

Senescence vividly marks the onset of the final stages of the life of a leaf, yet the triggers and
drivers of this process are still not fully understood. The hormone abscisic acid (ABA) is an …

Disassembly and degradation of the photosynthetic protein complexes during autumn
senescence, a vital step to ensure efficient nutrient relocalization for winter storage, is poorly …

Drylands cover more than 40% of global land surface and will continue to expand by 10% at
the end of this century. Understanding the resistance mechanisms of native species is of …

Autumn senescence is characterised by spatial and temporal heterogeneity. We show that
senescing birch (Betula spp.) leaves had lower PSII activity (probed by the FV/FM …
