TL;DR: Evaluation of the dehydration responses and natural variations of these metabolites in rice leaf not only suggested the coordinated regulation of abscisic acid with metabolites such as serotonin derivative(s), polyamine conjugates under drought stress, but also revealed some C-glycosylated flavones as the potential markers for the discrimination of indica and japonica rice subspecies.

TL;DR: The results demonstrate that the CRISPR-Cas system can be exploited as a powerful tool for gene targeting and precise genome editing in plants and suggests that mismatch position between gRNA seed and target DNA is an important determinant of the gRNA-Cas9 targeting specificity.

TL;DR: Mechanistic new insights are revealed into the mode of action of this versatile TF that is involved in JA-regulated plant development, lateral and adventitious root formation, flowering time, and shade avoidance syndrome.

TL;DR: It is shown that the CRISPR–Cas system can be applied to generate targeted gene mutations and gene corrections in plants, and the system can also be readily engineered to achieve deletion of large DNA fragments and for multiplex gene editing in plants.

TL;DR: This review focuses on the emerging complexity of the SOS signaling and SOS protein functions, and highlights recent understanding on how the SOS proteins contribute to different responses to salt stress besides ion homeostasis.

TL;DR: A direct interconnection between CBL-CIPK-mediated Ca(2+) signaling and ROS signaling in plants is identified and evidence for a synergistic activation of the NADPH oxidase RBOHF is provided by directCa(2+)-binding to its EF-hands and Ca( 2+)-induced phosphorylation by CBL1/9-C IPK26 complexes.

TL;DR: Within a higher plant, strigolactones appear to be involved in controlling the balance of resource distribution via strategic modification of growth and development, which changes root growth and promotes fungal symbiosis to enhance phosphate intake.

TL;DR: This review focuses on intercellular communication between the pollen grain/pollen tube including the sperm cells with the various sporophytic maternal tissues and the cells of the female gametophyte.

TL;DR: It is concluded that the four Ib subgroup bHLH proteins are required and possess redundant functions with differential significance for activation of iron-deficiency responses and uptake in Arabidopsis.

TL;DR: Two pH sensors generated by combining the improved-solubility feature of solubility-modified green fluorescent protein with the pH-sensing capability of the pHluorins and codon optimized for expression in Arabidopsis are excellent pH sensors for visualization and quantification of pH in vivo, respectively.

TL;DR: This review summarizes studies of protein-protein interactions for WRKY transcription factors and discusses how the interacting partners contribute, at different levels, to the establishment of the complex regulatory and functional network of WRKYcription factors.

TL;DR: Genetic analysis revealed that the effects of PRR37 and Ghd7 alleles on heading date are additive, andPRR37 down-regulates Hd3a expression to suppress flowering under long-day conditions, demonstrating that natural variations in PRR 37/Hd2 andGhd7/HD4 have contributed to the expansion of rice cultivation to temperate and cooler regions.

TL;DR: In the past few years, the use of sequence-specific nucleases for efficient targeted mutagenesis has provided plant biologists with a powerful new approach for understanding gene function and developing new traits.

TL;DR: The transcription factor bZIP11 has recently been identified as a new player in the T6P/SnRK1 regulatory pathway, which has important consequences for crop production, for example, in the developing wheat grain and during the growth of potato tubers.

TL;DR: The roles of plant hormones in rice immunity are summarized, their interplay/crosstalk mechanisms and the complex regulatory network of plant hormone pathways in fine-tuning rice immunity and growth are discussed.

TL;DR: Evidence is provided for a novel endogenous role for strigolactone response within the root during mycorrhizal development, in addition to the action of striglactones on the fungal partner.

TL;DR: Can all plants improve stress tolerance when associated with appropriate microbial partners?

TL;DR: A model has been derived that can be used to design and prepare active SL analogs and it is shown that the three principal functions use a distinct perception system for bioactivity.

TL;DR: A functional YUCCA pathway of auxin biosynthesis in potato that may be exploited to alter plant responses to the environment is suggested.

TL;DR: Emerging data have revealed that at least some MtN3/saliva/SWEET-type proteins may regulate different physiological processes by facilitating ion transport via interaction with ion transporters or as sugar transporter.

TL;DR: A model for the molecular interactions between rice and the BPH is proposed, although many details remain to be investigated that are valuable for molecular design of BPH-resistant rice varieties.

TL;DR: It is reported that BIFUNCTIONAL NUCLEASE1 (BFN1), a well-known senescence-enhanced gene, is directly regulated by ORE1, and chromatin immunoprecipitation (ChIP) demonstrates in vivo binding of Ore1 to the BFN1 promoter.

TL;DR: This paper presents a meta-analyses of the determinants of infectious disease outbreaks in eight operation theatres and shows clear patterns of disease progression that are consistent with those seen in the literature on infectious disease.

TL;DR: It is shown that a successful heat response depends on the integrity of epigenetic pathways and evidence that heat-dependent gene expression is influenced by closely located transposon sequences and read-through transcription is provided.

TL;DR: The aerial parts of land plants are covered with cuticular waxes that limit non-stomatal water loss and gaseous exchanges, and protect plants from ultraviolet radiation and pathogen attacks.

TL;DR: Emerging evidence suggests that these genes orchestrate crosstalk between biotic and abiotic stresses through a variety of mechanisms, including regulation of cellular energy homeostasis and modification of synergistic and/or antagonistic interactions between the stress hormones salicylic acid, ethylene, jasmonic acid, and abscisic acid.

TL;DR: Evidence is provided for an essential role of the vacuolar potassium channel TPK1 in salt-stress adaptation as a target of calcium-regulated stress signaling pathways involving Ca(2+), Ca( 2+)-dependent kinases, and 14-3-3 proteins.

TL;DR: Major strigolactones produced by rice and tobacco were purified and their stereochemical structures were determined definitely by comparing with optically pure synthetic standards for spectroscopic data.

TL;DR: The impressive progress made during recent years in elucidating the components of the sterol and BR metabolic and signaling pathways is reviewed, and emerging insights into the regulations of these pathways are discussed.

TL;DR: This review summarizes the recent research on the characterization of those genes in both M. oryzae and rice that are important for the PAMP- and effector-triggered immunity recognition and signaling processes.
