Soil biota and plant diversity biota, including symbionts such as mycorrhizal fungi nitrogen-fixing bacteria, well fungal bacterial pathogens, affect terrestrial growth patterns (see the Perspective by van der Putten). Teste et al. monitored survival in Australian shrubland species paired with soil from plants of same other that use different nutrient acquisition strategies. Plant-soil feedbacks appear to drive local through interactions between types their associated biota. Bennett studied...
Herbicide rate cutting is an example of poor use agrochemicals that can have potential adverse implications due to rapid herbicide resistance evolution. Recent laboratory-level studies revealed herbicides at lower-than-recommended rates result in evolution rigid ryegrass populations. However, crop-field-level until now been lacking. In this study, we examined the impact low diclofop on a herbicide-susceptible population grown either field wheat crop or potted plants maintained field....
Leaf photosynthesis (A) is limited by mesophyll conductance (gm), which influenced both leaf structure and the environment. Previous studies have indicated that upper bound for gm declines as dry mass per area (LMA, an indicator of structure) increases, extrapolating to zero at a LMA about 240 g m−2. No data exist on its response environment species with values higher than 220 In this study, laboratory measurements gas exchange in vivo chlorophyll fluorescence were used concurrently derive...
Summary As an increasing number of plant genome sequences become available, it is clear that gene content varies between individuals, and the challenge arises to predict a species. However, comparison often confounded by variation in assembly annotation. Differentiating true absence or annotation essential for accurate identification conserved variable genes Here, we present de novo B. napus cultivar Tapidor with improved Brassica Darmor ‐bzh . Both cultivars were annotated using same method...
Synthetic herbicides have been used globally to control weeds in major field crops. This has imposed a strong selection for any trait that enables plant populations survive and reproduce the presence of herbicide. Herbicide resistance must be minimized because it is limiting factor food security global agriculture. represents huge challenge will require great research efforts develop strategies as alternatives dominant almost exclusive practice weed by herbicides. Weed scientists, ecologists...
Weed resistance to foliar herbicides has dramatically increased worldwide in the last two decades. As a consequence, current practices of weed management have changed, with an adoption soil-applied restore control herbicide-resistant weeds. We foresee metabolism-based and cross-resistance as potential global consequence widespread new old herbicides. Thus, aim this study is use computer simulation modelling quantify rank risk weeds evolving under different usage strategies (single herbicide...
Construction of tree architectural databases over years is time consuming and cannot easily capture event dynamics, especially when both topology geometry are considered. The present project aimed to bring together models in a single simulation such that the architecture an apple may emerge from process interactions. This integration was performed using L-systems. A mixed approach developed based on stochastic simulate plant mechanistic model for geometry. succession growth units (GUs) along...
Abstract Weed management is a critically important activity on both agricultural and non‐agricultural lands, but it faced with daunting set of challenges: environmental damage caused by control practices, weed resistance to herbicides, accelerated rates dispersal through global trade, greater impacts due changes in climate land use. Broad‐scale use new approaches needed if be successful the coming era. We examine three likely prove useful for addressing current future challenges from weeds:...
Abstract Restoring resilient ecosystems in an era of rapid environmental change requires a flexible framework for selecting assemblages species based on functional traits. However, current trait‐based models have been limited to algorithms that select only converge specified average trait values, and could not accommodate the common desire among restoration ecologists generate functionally diverse assemblages. We solved this problem by applying nonlinear optimization algorithm solve relative...
Leaf dry mass per area (LMA) is a composite parameter relating to suite of structural traits that have the potential influence photosynthesis. However, extent which each these contributes variation in LMA and photosynthetic rates not well understood, especially at high end spectrum. In this study, genus Banksia (Proteaceae) was chosen as model group, key such LMA, leaf thickness, density were measured 49 species. Based on trait obtained, subset 18 species displaying wide range 134–507 g m−2...
Many Australian legumes have evolved in low-phosphorus (P) soils and low-rainfall areas. Therefore a study was made of the interaction soil [P] water availability on growth, photosynthesis, water-use efficiency (WUE) P nutrition two native with pasture potential, Cullen australasicum C. pallidum, widely grown exotic legume, lucerne (Medicago sativa).
Current knowledge suggests that the mechanisms by which plants communicate information take numerous forms. Previous studies have focussed their attention on communication via chemicals, contact and light; other methods of interaction between remained speculative. In this study we tested ability young chilli to sense neighbours identify relatives using alternative mechanism(s) recognised plant pathways. We found presence a neighbouring had significant influence seed germination even when all...
The need to integrate the ever-expanding body of knowledge in plant sciences has led development sophisticated modelling approaches. This special issue focuses on functional–structural (FSP) models, which are result cross-fertilization between domains science, computer science and mathematics. FSP models simulate growth morphology individual plants that interact with their environment, from complex community properties emerge. can be used for a broad range research questions across...
