Associations between shoot-level water relations and photosynthetic responses to water and light in 12 moss species

In vascular plants, water and carbon economics are closely coupled. In mosses, this relationship has been little studied but a strong coupling is expected because photosynthesis depends heavily on water content in these plants, i.e. photosynthetic rates are impaired when mosses dry out but also when they get too wet. In a recent study published […]

Functional traits partially mediate the effects of chronic anthropogenic disturbance on the growth of a tropical tree

Understanding how trees mediate the effects of chronic anthropogenic disturbance is fundamental to developing sustainable forest management strategies. Several tree species in Africa are repeatedly defoliated at large scale by cattle breeders to feed livestock. The same tree species are also often debarked for medicinal purposes. These human-induced disturbances can lead to biomass loss and […]

Presence of fruits decreases probability of retaining flowers in a sequentially flowering plant

Both intrinsic and extrinsic plant processes affect the fate of flowers along an inflorescence in sequentially flowering plants. In a study recently published in AoB PLANTS, Jadeja & Tenhumberg investigated mechanisms underlying variation in fruiting patterns of sequentially flowering plants using the wild flower Yucca glauca (Family: Agavaceae). These plants start opening flowers on the bottom […]

Rarity and nutrient acquisition relationships before and after prescribed burning in an Australian box-ironbark forest

Nutrient cycling is greatly influenced by dominant plants that contribute high amounts of leaf litter to soils; however, less-dominant and rare species can play key roles in nutrient cycling if they have unique nutrient acquisition traits and provide high-quality litter. In many parts of the world, wildfire is likely to become more frequent and intense […]

Defence signalling marker gene responses to hormonal elicitation differ between roots and shoots

Plants responses to environmental stresses are regulated by signalling hormones, such as jasmonic acid, salicylic acid, ethylene and abscisic acid. Plant scientists commonly use marker genes to study which signalling pathways are activated, however, these markers were designed and tested for shoot responses in Arabidopsis thaliana. It is unclear whether the paradigms based on experiments […]

Degradation of chlorophyll and synthesis of flavonols during autumn senescence – the story told by individual leaves

Chlorophylls are degraded and flavonoids synthesized during autumn senescence of deciduous trees. In a recent study by Mattila et al. published in AoB PLANTS, chlorophyll and flavonol contents of individual leaves of a number of deciduous tree species (rowan, Norway maple, silver birch and bird cherry) were monitored non-destructively throughout the autumn. Loss of chlorophyll […]

Functional acclimation across microgeographic scales in Dodonaea viscosa

Intraspecific plant functional trait variation provides mechanistic insight into persistence and can infer population adaptive capacity. However, most studies explore intraspecific trait variation in systems where geographic and environmental distances co-vary. Such a design reduces the certainty of trait–environment associations, and it is imperative for studies that make trait–environment associations be conducted in systems where […]

Inherent variation of functional traits in winter and summer leaves of Mediterranean seasonal dimorphic species: evidence of a ‘within leaf cohort’ spectrum

Leaf morphological, physiological and biochemical traits tend to vary in a coordinated manner as described by the Leaf Economics Spectrum (LES). Nevertheless, some aspects, such as how the leaf trait variation sources affect LES predictions, are still little investigated. In a recent study published in AoB PLANTS, Puglielli and Varone test whether leaf trait variations […]

Biotic- and abiotic-driven variations of the night-time sap flux of three co-occurring tree species in a low subtropical secondary broadleaf forest

Although several studies on the night-time water use of different plant species have been reported, comparative studies under the same climatic conditions of a region are scarce. A recent study by Wang et al. published in AoB PLANTS aimed to analyse the inter- and intra-specific variations in night-time water use in relation to environmental factors […]

Within- and trans-generational plasticity: seed germination responses to light quantity and quality

Plants respond not only to the environment in which they find themselves, but also to that of their parents. The combination of within- and trans-generational phenotypic plasticity regulates plant development. The light environment also regulates many aspects of plant development, including seed germination. In a recent study published in AoB PLANTS, Vayda et al. investigate […]

Variation in the degree of reciprocal herkogamy affects the degree of legitimate pollination in a distylous species, Primula chungensis

Distyly is a well-known floral syndrome, first identified by Charles Darwin, characterised by the flowers within a population showing reciprocal placement of the anthers and stigma. In a recent study published in AoB plants, Jiang et al. use distyly as a model to determine how a key floral syndrome is shaped by nature. Primula chungensis, […]
