Abstract The existence of trait coordination in roots and leaves has recently been debated, with studies reaching opposing conclusions. Here, we assessed across twelve boreal tree species. We show that there is only partial evidence for above-belowground “fast-slow” economic traits species, i.e., while N content were positively correlated, as well dry matter content, root leaf had no significant relationship. For resource acquisition (i.e. related to light capture nutrient uptake) did not find strong coordination, specific length area correlated. further site explained between 0 7% the total variation, within-site variation contributed substantially a large number (1.6–96%), more so morphological than traits. This likely influences strength found species our study. Understanding sources relationships can contribute improving global regional C cycling models. However, fine-scale environmental variability should be accounted given its importance driving variation.

Summary Plant trait variation drives plant function, community composition and ecosystem processes. However, our current understanding of disproportionately relies on aboveground observations. Here we integrate root traits into the global framework form function. We developed tested an overarching conceptual that integrates two recently identified gradients with a well‐established framework. confronted novel published relationships between above‐ belowground analogues multivariate analyses 2510 species. Our represent leaf conservation (specific area, nitrogen concentration, tissue density), collaboration gradient (root diameter specific length) size (plant height rooting depth). found integrated, whole‐plant space required as much four axes. The main axes represented fast–slow ‘conservation’ which fine‐root were well aligned, ‘collaboration’ in roots. additional separate, orthogonal for depth. This perspective multidimensional nature better encompasses function influence surrounding environment.

Plant population density is an important variable in agronomy and forestry offers experimental way to better understand plant-plant competition. We made a meta-analysis of responses even-aged mono-specific stands by quantifying for 3 stand 33 individual plant variables 334 experiments how much both biomass phenotypic traits change with doubling density. Increasing increases standing crop per area, but decreases the mean size its individuals, mostly through reduced tillering branching. Among traits, stem diameter negatively affected, height remains remarkably similar, partly due increased length-to-mass ratio allocation stems. The reduction caused lower photosynthetic rate, mainly shading part foliage. Total seed mass also strongly reduced, marginally seed, because numbers. Plants generally have fewer shoot-born roots, their overall rooting depth seems hardly affected. plasticity high densities correlate those low light, less nutrients, suggesting that at density, affects plants more than nutrient depletion.

Plant root traits play a crucial role in resource acquisition and crop performance when soil nutrient availability is low. However, the respective trait responses are complex, particularly at field scale, poorly understood due to difficulties phenotyping monitoring, inaccurate sampling, environmental conditions. Here, we conducted systematic review meta-analysis of 50 studies identify effects nitrogen (N), phosphorous (P), or potassium (K) deficiencies on systems common crops. Root length biomass were generally reduced, while per shoot was enhanced under N P deficiency. decreased by 9% deficiency 14% deficiency, reduced 7% N-deficient 25% P-deficient soils. increased 33% deficient 51% The root-to-shoot ratio often (44%) N-poor conditions, but no consistent response P-deficiency found. Only few K-deficiency suited our approach and, those cases, differences morphological reported. We encountered following drawbacks performing this analysis: limited number investigated timing severity deficiencies, missing data (e.g., status time stress), impact other conditions field. Nevertheless, analysis indicates that, general, root-length-to-shoot-biomass ratios crops, with impacts decreasing order > K. Our resolved inconsistencies that found individual experiments, led better understanding physiological mechanisms underlying plasticity fields low availability.

Plants often associate with specialized decomposer communities that increase plant litter breakdown, a phenomenon is known as the 'home-field advantage' (HFA). Although concept of HFA has long considered only role soil microbial community, explicit consideration community on foliage before fall (i.e. phyllosphere community) may help us to better understand HFA. We investigated occurrence in presence vs absence and found effects were smaller when removed. propose priority interactions between organisms can explain positive at home, suggest path forward for further investigation.

Climate warming is predicted to affect temperate forests severely, but the response of fine roots, key plant nutrition, water uptake, soil carbon, and nutrient cycling unclear. Understanding how roots will respond increasing temperature a prerequisite for predicting functioning in warmer climate.

Fine root biomass (FRB) production were 17% 128% higher warmed plots, respectively, years.
