TL;DR: Melatonin is an important modulator of gene expression related to plant hormones, e.g. in auxin carrier proteins, as well as in metabolism of indole-3-acetic acid (IAA), gibberellins, cytokinins, abscisic acid and ethylene.

TL;DR: A holistic and comparative approach is proposed to assess the mode of action of Si between plant trait types and between biotic and abiotic stressors, highlighting potential pathways highlighted by recent empirical evidence.

TL;DR: This review puts SCW biosynthesis in a cellular context, with the aim of integrating molecular biology and biochemistry with plant cell biology, and reflects the fact that protoxylem tracheary elements have proven to be the most amenable experimental system in which to study the cell biology of SCWs.

TL;DR: BVCs have good potential for use as biostimulants and protectants to improve plant health and further advances in the development of suitable technologies and preparing standards and guidelines will help in the application of BVCs in crop protection and health.

TL;DR: CRootBox is a fast and flexible functional-structural root model that is based on state-of-the-art computational science methods to facilitate modelling of root responses to environmental conditions as well as the impact of roots on soil.

TL;DR: Root hairs increase exudation and spatial rhizosphere extension, which probably enhance rhizospheric interactions and nutrient cycling in larger soil volumes and may therefore be beneficial to plants under nutrient-limiting conditions.

TL;DR: The olive is a relevant model for improving knowledge of domestication processes in clonally propagated perennial crops, particularly those of the Mediterranean Basin, and is argued that more detailed ecological genomics studies of wild and cultivated olives are crucial to improve understanding of olive domestication.

TL;DR: It is argued that the integration of advances in genomics will significantly improve the precision and targeted identification of potentially useful variation in the wild relatives of wheat, providing new opportunities to contribute to yield and quality improvement, tolerance to abiotic stresses, resistance to emerging biotic stresses and resilience to weather extremes.

TL;DR: The PMT is reviewed by going back to its initial formulation, stating its explicit and implicit properties and discussing them in the light of current biological knowledge and experimental evidence in order to identify the validity and range of applicability of the theory.

TL;DR: Xylogenesis in semi-arid regions with dry winters and springs can start when both critical temperature and precipitation thresholds are reached, suggesting that temperature was not the only factor initiating xylem growth under cold and dry climatic conditions.

TL;DR: There is a great need to understand photosynthesis dynamics from a mechanistic and biological viewpoint especially when applied to the field of ‘phenomics’ which typically uses large genetically diverse populations of plants.

TL;DR: Application of exogenous melatonin not only increased endogenous H2O2 content but also induced LR formation in alfalfa seedlings, and pharmacological and genetic evidence revealed that endogenous melatonin-triggered LR formation was H1O2-dependent.

TL;DR: Since high-quality data are a key requirement in modelling, a range of must-have parameters and variables is proposed.

TL;DR: The utility of a root architectural phenotype is determined by whether the constituent phenes are synergistic or antagonistic, which has implications for understanding plant evolution and also for the breeding of more stress-tolerant crop phenotypes.

TL;DR: High-accuracy 3D evaluation of reconstruction quality indicated that dynamic capture of the 3D canopy based on the MVS approach can be potentially used in 3D phenotyping for applications in breeding and field management.

TL;DR: The beginning of the rainy season was the most favourable period for seed germination in cerrado, and the germination phenology was controlled by both the timing of seed dispersal and seed dormancy.

TL;DR: The results presented suggest that microbial inhabitants of floral nectar can make nectar characteristics variable among flowers through divergent effects of yeasts and bacteria on nectar chemistry and availability, probably modifying plant-pollinator interactions.

TL;DR: This review focuses on the morphological responses of roots to mechanical stress, and several modifications in root morphology are commonly reported: decreased root size, radial swelling accompanied by increased radial dimension of the cortex cell layers and enhanced cap cell sloughing.

TL;DR: This study supports the adoption of a broadly defined Salvia and treats EA Salvia as a sub genus, Glutinaria, recognizing eight sections within this subgenus.

TL;DR: The results suggest that CsLsi2 is a silicon efflux transporter gene in cucumber, one of the few dicots with a relatively high capacity for silicon accumulation.

TL;DR: Next-generation sequencing and morphological cladistic techniques are integrated to clarify the phylogeny of bee orchids and strongly support the monophyly of nine out of ten groups previously circumscribed using nrITS and resolve three major clades.

TL;DR: The results demonstrate that SPMS activity is not a novel feature developed solely in the angiosperm lineage of seed plants but also exists as a secondary property in the Scots pine SPDS enzyme, and associate PsACL5 with the development of vascular structures in Scots pine.

TL;DR: The proposed functional signature concept allows the systematic integration of plant functional traits and phylogeny into the study of endemism hotspots and refugia, but more data on functional traits in these entities are urgently needed.

TL;DR: N form was an important factor affecting the magnitude and direction of the RPE via its effect on rhizosphere pH and needs to be considered in SOC and RPE modelling.

TL;DR: The overall results suggest that near-complete hybrid seed failure can evolve fairly rapidly and without apparent divergence in reproductive phenology/biology.

TL;DR: Polyploidy and contrasting reproductive traits between cytotypes have promoted shifts in niche optima, and increased ecological tolerance and niche divergence.

TL;DR: The results contradict the over-simplistic notion that global vegetation always responds with decreasing gs to elevated CO2, a finding that has important implications for predicting future vegetation feedbacks on the hydrological cycle at the regional level.

TL;DR: This study highlights the importance of adding a characterization of diel variation of scent emission rates to comparative studies of floral scent, which so far have often focused on scent composition only.

TL;DR: For woody plants low SLA is a phenotypic and probably adaptive response to nitrogen stress, which drives the predominance of species with ever-decreasing SLA towards less fertile habitats and the importance of quantifying intraspecific trait variation to improve understanding of species distributions across a vegetated landscape is highlighted.

TL;DR: A high level of recombination occurs between the chromosomes of wheat and Ae.
