Data from: Trait variation and performance across varying levels of drought stress in cultivated sunflower (Helianthus annuus L.)
<p><strong>Background and Aims:</strong> Drought is a major agricultural challenge that is expected to worsen with climate change. A better understanding of drought responses has the potential to inform efforts to breed more tolerant plants. We assessed leaf trait variation and covariation in cultivated sunflower (<em>Helianthus annuus L</em>.) in response to water limitation.</p> <p><strong>Methods: </strong>Plants were grown under four levels of water availability and assessed for environmentally induced plasticity in leaf stomatal and vein traits as well as biomass (performance indicator), mass fractions, leaf area, leaf mass per area, and chlorophyll content.</p> <p><strong>Key Results:</strong> Overall, biomass declined in response to stress; these changes were accompanied by responses in leaf-level traits including decreased leaf area and stomatal size, and increased stomatal and vein density. The magnitude of trait responses increased with stress severity and relative plasticity of smaller-scale leaf anatomical traits was less than that of larger-scale traits related to construction and growth. Across treatments, where phenotypic plasticity was observed, stomatal density was negatively correlated with stomatal size and positively correlated with minor vein density, but the correlations did not hold up within treatments. Four leaf traits previously shown to reflect major axes of variation in a large sunflower diversity panel under well-watered conditions (i.e., stomatal density, stomatal pore length, vein density, and leaf mass per area) predicted a surprisingly large amount of the variation in biomass across treatments, but trait associations with biomass differed within treatments. Additionally, the importance of these traits in predicting variation in biomass is mediated, at least in part, through leaf size.</p> <p><strong>Conclusions:</strong> Our results demonstrate the importance of leaf anatomical traits in mediating drought responses in sunflower, and highlight the role that phenotypic plasticity and multi-trait phenotypes can play in predicting productivity under complex abiotic stresses like drought.</p>

The effect of cell density on biomass and fatty acid productivity during cultivation of Rhodomonas salina in a tubular photobioreactor - the dataset.
<p>The microalga Rhodomonas salina is widely used in aquaculture. There is a need for<br> optimization of the growth of the microalgae and its content of essential fatty acids.<br> Here, the fatty acid profile of Rhodomonas in relation to cell density during cultivation<br> in a tubular PBR is investigated. It is expected that cell density is an important<br> factor in controlling productivity and fatty acid content of the microalgae because<br> cell density is important in determining light availability due to the self-shading of the<br> algae. The carbon productivity as a function of cell density is described by a saturation<br> curve. The carbon productivity and the productivity of total fatty acids are lowest<br> at the lowest cell density, and independent of cell density at higher cell densities.<br> The relative contribution of the two poly-unsaturated fatty acids eicosapentaenoic<br> acid (EPA) and docosahexaenoic acid (DHA) increases with increasing cell density and<br> saturates at 1 × 106 cells/ml. We conclude that large-scale production of Rhodomonas<br> in this tubular PBR should take place at cell densities of 1 × 106 cells/ml, while there<br> are indications for increasing difficulties in maintaining steady-state production in<br> this PBR at higher cell densities.</p>

Afrotropical secondary forests exhibit fast diversity and functional recovery, but slow compositional and carbon recovery after shifting cultivation
<p>Question: Human disturbance is increasingly affecting forest dynamics across the tropics. Forests can recover via natural secondary succession to pre-disturbance levels of biodiversity, species composition, and ecosystem carbon stocks. Central Africa will be subject to increasingly high shifting cultivation pressure in the next decades, but succession trajectories of these ecosystem properties are still poorly known for the Congo basin. We addressed two questions: (1) how does taxonomic and functional composition and diversity shift? (2) How fast do aboveground carbon stocks recover during secondary succession in tropical forests?</p> <p>Location: Central Congo basin</p> <p><span>Methods: We conducted an inventory of trees (DBH ≥10 cm diameter), measured species traits and soil texture and carbon content in 18 plots, located along six secondary succession stages (i.e. from agricultural to old growth forest sites). We measured tree diameter, height for 20% of trees distributed across diameter classes, wood traits from all species, and leaf traits from species that contributed to 85% of the plot basal area.</span></p> <p>Results: We showed that secondary forests recover relatively fast in terms of tree species diversity, alpha functional diversity, and fine root carbon, with near-old-growth forest values after six decades past disturbance, while floristic composition exhibited slower recovery. Secondary forests only partially shifted from acquisitive to a conservative life-history, with shifts in leaf traits being largely decoupled from wood traits. Only 43% of above-ground carbon recovered after 60 years of forest regrowth, potentially through a slow recovery of the large-sized tree stems that dominate carbon stocks of old-growth forests.</p> <p>Conclusions: Our findings underline the capacity of Afrotropical forests to recover species and alpha functional diversity after clear-cutting through shifting cultivation. Simultaneously, old-growth forests harbors a particular floristic community and store a large quantity of carbon with much longer recovery trajectories, stressing the need for conservation of these forests in the Congo Basin.</p>
Mycorrhizal fungi alter root exudation to cultivate a beneficial microbiome for plant growth
<p>Arbuscular mycorrhizal (AM) fungi traditionally form symbioses with most plant species. Although AM fungi have critical effects on microbial communities, the pathways showing how AM fungi shape rhizosphere bacterial communities and their functions are rarely explored. Through three systematic experiments, AM fungi-bacteria interactions were first investigated in the rhizosphere of <em>Lotus</em> <em>japonicus</em>, then the interactions were confirmed by a second experiment with wild-type and a mycorrhiza-defective mutant <em>ljcbx</em> of <em>L</em>. <em>japonicus</em>. The mechanisms were presented by adding core bacteria and AM fungi to the plant rhizosphere with the third experiment. We found that AM fungi-bacteria interactions enhanced host plant growth and identified a core bacterial group that uniquely enhanced host plant growth. Adding core bacteria and AM fungi promoted host growth and nutrient acquisition compared to adding AM fungi or core bacteria independently. Allelopathic substances secreted by AM fungal colonizing host roots to recruit the rhizosphere bacteria were detected by the multi-omics joint analysis, showing that arachidonic acid was the main allelopathic substance that affected AM fungi–bacteria interactions. Our findings provide direct evidence that mycorrhizal infection simulated root exudation, such as arachidonic acid, recruited a beneficial microbiome to the host rhizosphere, increasing plant growth and soil nutrient turnover.</p>

Data from: Does the reduction of seed dormancy during ex situ cultivation affect the germination and establishment of plants reintroduced into the wild?
<p><span>1. Plants or seeds produced in botanic gardens or nurseries have become an important source of plant material for reintroductions or population reinforcements. However, recent research has shown that these living collections bear the risk of being genetically impoverished and adapted to the artificial habitat. In particular, many studies have reported a decline of seed dormancy during ex situ cultivation, which may compromise their suitability for reintroduction programs. However, the impact of those ex situ-derived changes on the germination and establishment of reintroduced plant populations is still unclear. </span></p> <p><span>2. We studied the germination behaviour, population establishment and plant fitness over three years of reintroduced plants of the short-lived perennial <em>Digitalis</em> <em>lutea</em>, comparing plants grown from (1) a 30-year botanic garden population, (2) seeds from a seed bank representing the initial starting point of the botanic garden culture, and (3) a re-sampled corresponding wild population. </span></p> <p><span>3. Under laboratory conditions, wild-collected seeds required cold stratification to germinate, whereas seeds from the garden population germinated without stratification. This pattern was strongly reduced in an outdoor pot experiment, where only a few garden seeds germinated before winter, and all seeds remained dormant when seeded in the natural area of origin. In a transplant experiment, reintroduced plants from the wild population outperformed both, the garden and the seed bank plants, in their fitness in the first 3 years after reintroduction suggesting adaptation to current climatic conditions. </span></p> <p><span>4. Synthesis and Applications: Our study demonstrates that trait changes that occurred during ex situ cultivation can negatively impact the establishment of reintroduced plants. We conclude that wild plant material collected from contemporary populations is best suited for reintroduction and should be preferred over ex situ-cultivated and seed bank stored material, especially when the cultivation spanned multiple generations. However, our study also shows that germination requirements change in complex ways, and the loss of dormancy observed under laboratory conditions may not always be directly transferable to natural conditions. When established standards are respected, ex situ propagated material may thus still be a valuable resource, especially when wild material is not available in sufficient quantities. </span></p>
Dataset related to article: Differential effect of climate of origin and cultivation climate on structural and biochemical plant traits
<p><span>Exploring patterns and causes of intraspecific trait variation is crucial for a better understanding of the effects of climate change on plant populations and ecosystems. However, our current understanding of the intraspecific trait variation is mainly based on structural (morphological) traits, and we have limited knowledge on patterns and causes of variation in biochemical traits (e.g., leaf pigments), which are also crucial for plant adaptation. As a result, we also do not know how similar the climatic effects on structural versus biochemical traits are. </span></p> <p><span>Using plant traits from 110 genotypes representing 11 <em>Festuca</em> <em>rubra</em> populations grown in 4 different climates, we studied trait covariation among structural traits (linked to fitness, resource use, gas exchange, and reproduction) and biochemical traits (linked to photosynthesis, photoprotection, and oxidative stress). We also disentangled the relative role of the climate of origin and the climate of cultivation in the structural versus biochemical traits and tested for adaptive plasticity in the traits. </span></p> <p><span>We found that 1) biochemical traits did not covary with structural traits and represent independent '<em>photoharvesting</em> – <em>photoprotection</em>' strategy dimension of functional variation; 2) interactive effects of climate of origin and cultivation were more pronounced for biochemical than structural traits</span>. 3) T<span>rait plasticity was affected by the climate of origin (</span>precipitation and temperature as well as their interaction<span>); 4) </span><em>F. rubra</em> showed both adaptive and mal-adaptive plasticity, and adaptiveness depended upon trait type, cultivation climate, and climate of origin.</p> <p><span>Overall, our results suggest that structural and biochemical plant traits respond differentially to climate and thus the response of one group of traits cannot be predicted from the other. Responses are also strongly determined by interactions between the climate of origin and cultivation. Thus, more studies on variation in biochemical traits, their correspondence to other traits, and their variation with climate are needed. </span></p>
