TL;DR: This review will attempt to address several key questions related to the use of ROS as signaling molecules in cells, including the dynamics and specificity of ROS signaling, networking of ROS with other signaling pathways, ROS signaling within and across different cells, ROS waves and the evolution of the ROS gene network.

TL;DR: This review presents plant physiology in an 'omics' perspective, some of the new high-throughput and high-resolution phenotyping tools are reviewed and their application to plant biology, functional genomics and crop breeding is discussed.

TL;DR: PSII photodamage and the inhibition of repair are alleviated by photoprotection mechanisms associated with avoiding light absorption by the manganese cluster and successfully consuming or dissipating the light energy absorbed by photosynthetic pigments, respectively.

TL;DR: PIFs have broader roles than previously appreciated, functioning as a cellular signaling hub that integrates multiple signals to orchestrate regulation of the transcriptional network that drives multiple facets of downstream morphogenesis.

TL;DR: Fire has been a factor throughout the history of land-plant evolution and is not strictly a Neogene phenomenon, and Mesozoic fossils show evidence of fire-adaptive traits and, in some lineages, these might have persisted to the present as fire adaptations.

TL;DR: Recent progress made in unravelling molecular aspects of defence priming that is the accumulation of dormant mitogen-activated protein kinases, chromatin modifications and alterations of primary metabolism are summarized.

TL;DR: An overview of the multiplicity of NO production and scavenging pathways in plants is provided and which areas should be focused on in future studies to investigate the origin of fluctuations in the level of NO in plants are discussed.

TL;DR: This review assesses how transcriptional activators and repressors modulate lignin biosynthesis, and discusses crosstalk between the lignIn biosynthesis pathway and other physiological processes.

TL;DR: This review describes how the model plant Arabidopsis thaliana adapts its root system architecture to phosphate deficiency through inhibition of primary root growth, increase in lateral root formation and growth and production of root hairs, which all promote topsoil foraging.

TL;DR: The current understanding of and new insights into the mechanisms and functions of plant VSRs are highlighted.

TL;DR: More research is needed to understand how plants produce nectar, the most important mediator of their interactions with mutualistic animals.

TL;DR: It is hypothesize that the relative contribution of NB-LRR- and PRR-triggered immunity to nonhost resistance changes as a function of phylogenetic divergence time between host and nonhost.

TL;DR: This work reviews events with particular reference to amino acid catabolism and its role in supporting the tricarboxylic acid cycle and direct electron supply to the ubiquinone pool of the mitochondrial electron transport chain in plants.

TL;DR: This review examines recent outcomes from diverse botanical disciplines to synthesize for the first time a holistic view on the evolutionary history of the mustard family.

TL;DR: Using modified chlorophylls to extend the spectral region of light that drives photosynthetic organisms to harvest sunlight at different wavelengths is discussed.

TL;DR: Two key biotechnology approaches, molecular breeding and genetic engineering, and their integration with conventional breeding to develop crops that are more tolerant of abiotic stresses are reviewed.

TL;DR: It is proposed that pollination could be successfully restored in degraded ecosystems through the use of targeted restoration plantings to attract and sustain pollinators and increased knowledge of the ecological requirements of pollinators.

TL;DR: Some of the developmental traits they control along with possible interactions between miRNA and their targets are discussed, and they present important targets for biotechnology applications.

TL;DR: Porphyra umbilicalis genome project will further elucidate proteins associated with stress tolerance, and phylogenomic and transcriptomic investigations of Porphyra sensu lato could elucidate tradeoffs made during physiological acclimation and factors associated with life-history evolution in this ancient lineage.

TL;DR: In plants iron-sulfur (Fe-S) proteins are found in the plastids, mitochondria, cytosol and nucleus, where they are essential for numerous physiological and developmental processes.

TL;DR: New evidence is at last providing insight into the biological relevance of cellular polyploidy, demonstrating that endoreplication is essential for developmental processes, such as cell fate maintenance, and is a prominent response to physiological conditions,such as pathogen attack or DNA damage.

TL;DR: The recent improvements and future prospects of using VIGS in plant biology are described and the non-stable nature of silencing is described as a potential problem and suitable solutions are described.

TL;DR: Both CRY signaling pathways rely on blue light-dependent interactions between the CRY photoreceptor and its signaling proteins to modulate gene expression changes in response to blue light, leading to altered developmental programs in plants.

TL;DR: It is proposed that nutrition and growth are linked by a multi-level, feed-forward cycle that regulates plant growth, development and metabolism via dedicated signaling pathways that mediate nutrient and hormonal regulation.

TL;DR: The need to map the activities of informational modulators to specific control points within the emerging model of jasmonate signaling is highlighted.

TL;DR: The current crop genome sequencing activities are reviewed, how variability in sequence quality impacts utility for different studies is discussed and a perspective for a paradigm shift in selecting crops for sequencing in the future is provided.

TL;DR: An ecological perspective to research outcomes from diverse disciplines is provided, showing that silicon is an important element in plant ecology that is worthy of greater attention.

TL;DR: An updated integrated conceptual model of the annual cycle of boreal and temperate trees is outlined by identifying ecophysiological phenomena that are particularly significant under climate warming.

TL;DR: In Arabidopsis leaves, the circadian clock controls the rate of degradation of starch to ensure an optimal carbon supply and hence continued growth during the night and shed new light on the integration of carbon assimilation and growth over the light-dark cycle.

TL;DR: In this paper, the authors outline maps of four energy-transducing thylakoid membranes for land plants and red and green algae, and find no defining structural feature that is common to all chloroplast gene products.
