controlling the interplay between agrobacterium tumefaciens and plants during the transient expression of proteins.	in may 2012, the first plant-derived biopharmaceutical protein received full regulatory approval for therapeutic use in humans. although plant-based expression systems have many advantages, they can suffer from low expression levels and, depending on the species, the presence of potentially toxic secondary metabolites. transient expression mediated by agrobacterium tumefaciens can be used to increase product yields but may also increase the concentration of secondary metabolites generated by pla ...	2015	25997443
epigenetic changes in hybrids.	genome-wide approaches to the study of hybrid vigor have identified epigenetic changes in the hybrid nucleus in arabidopsis (arabidopsis thaliana), maize (zea mays), and rice (oryza sativa). dna methylation associated with 24-nucleotide small interfering rnas exhibits transallelic effects in hybrids of arabidopsis and other species. some of the transmethylation changes are inherited and some affect gene expression. hybrids have larger leaves than those of the parents and have increases in cell s ...	2015	26002907
identification of jasmonic acid-associated micrornas and characterization of the regulatory roles of the mir319/tcp4 module under root-knot nematode stress in tomato.	micrornas (mirnas) are important transcriptional and post-transcriptional modulators of gene expression that play crucial roles in the responses to diverse stresses. to explore jasmonic acid (ja)-dependent mirna-mediated regulatory networks that are responsive to root-knot nematode (rkn), two small rna libraries were constructed from wild-type (wt) and ja mutant (spr2) plants. a total of 263 known mirnas and 441 novel mirnas were significantly regulated under rkn stress in the two libraries. the ...	2015	26002970
the role of cis-zeatin-type cytokinins in plant growth regulation and mediating responses to environmental interactions.	cytokinins (cks) are well-established as important phytohormonal regulators of plant growth and development. an increasing number of studies have also revealed the function of these hormones in plant responses to biotic and abiotic stresses. while the function of certain ck classes, including trans-zeatin and isopentenyladenine-type cks, have been studied in detail, the role of cis-zeatin-type cks (czs) in plant development and in mediating environmental interactions is less well defined. here w ...	2015	25998904
current understanding of grapevine defense mechanisms against the biotrophic fungus (erysiphe necator), the causal agent of powdery mildew disease.	the most economically important disease of cultivated grapevines worldwide is powdery mildew (pm) caused by the ascomycete fungus erysiphe necator. the majority of grapevine cultivars used for wine, table grape, and dried fruit production are derived from the eurasian grape species vitis vinifera because of its superior aroma and flavor characteristics. however, this species has little genetic resistance against e. necator meaning that grape production is highly dependent on the frequent use of ...	2015	26504571
the ethylene response factors erf6 and erf11 antagonistically regulate mannitol-induced growth inhibition in arabidopsis.	leaf growth is a tightly regulated and complex process, which responds in a dynamic manner to changing environmental conditions, but the mechanisms that reduce growth under adverse conditions are rather poorly understood. we previously identified a growth inhibitory pathway regulating leaf growth upon exposure to a low concentration of mannitol and characterized the ethylene response factor (erf)/apetala2 transcription factor erf6 as a central activator of both leaf growth inhibition and inducti ...	2015	25995327
manipulation of the xanthophyll cycle increases plant susceptibility to sclerotinia sclerotiorum.	the xanthophyll cycle is involved in dissipating excess light energy to protect the photosynthetic apparatus in a process commonly assessed from non-photochemical quenching (npq) of chlorophyll fluorescence. here, it is shown that the xanthophyll cycle is modulated by the necrotrophic pathogen sclerotinia sclerotiorum at the early stage of infection. incubation of sclerotinia led to a localized increase in npq even at low light intensity. further studies showed that this abnormal change in npq w ...	2015	25993128
characterization of arabidopsis transcriptional responses to different aphid species reveals genes that contribute to host susceptibility and non-host resistance.	aphids are economically important pests that display exceptional variation in host range. the determinants of diverse aphid host ranges are not well understood, but it is likely that molecular interactions are involved. with significant progress being made towards understanding host responses upon aphid attack, the mechanisms underlying non-host resistance remain to be elucidated. here, we investigated and compared arabidopsis thaliana host and non-host responses to aphids at the transcriptional ...	2015	25993686
a terpenoid phytoalexin plays a role in basal defense of nicotiana benthamiana against potato virus x.	terpenoid phytoalexins function as defense compound against a broad spectrum of pathogens and pests in the plant kingdom. however, the role of phytoalexin in antiviral defense is still elusive. in this study, we identified the biosynthesis pathway of a sesquiterpenoid phytoalexin, capsidiol 3-acetate as an antiviral response against rna virus potato virus x (pvx) in nicotiana benthamiana. nbtps1 and nbeah genes were found strongly induced by pvx-infection. enzymatic activity and genetic evidence ...	2015	25993114
experimental correlation of substrate position with reaction outcome in the aliphatic halogenase, syrb2.	the iron(ii)- and 2-(oxo)glutarate-dependent (fe/2og) oxygenases catalyze an array of challenging transformations, but how individual members of the enzyme family direct different outcomes is poorly understood. the fe/2og halogenase, syrb2, chlorinates c4 of its native substrate, l-threonine appended to the carrier protein, syrb1, but hydroxylates c5 of l-norvaline and, to a lesser extent, c4 of l-aminobutyric acid when syrb1 presents these non-native amino acids. to test the hypothesis that pos ...	2015	25965587
fine mapping and characterization of candidate genes that control resistance to cercospora sojina k. hara in two soybean germplasm accessions.	frogeye leaf spot (fls), caused by the fungus cercospora sojina k. hara, may cause a significant yield loss to soybean growers in regions with a warm and humid climate. two soybean accessions, pi 594891 and pi 594774, were identified to carry a high level of resistance similar to that conditioned by the rcs3 gene in 'davis'. previously, we reported that the resistance to fls in these two plant introductions (pis) was controlled by a novel gene (s) on chromosome 13 that is different from rcs3. to ...	2015	25993056

the cost of phage resistance in a plant pathogenic bacterium is context-dependent.	parasites are ubiquitous features of living systems and many parasites severely reduce the fecundity or longevity of their hosts. this parasite-imposed selection on host populations should strongly favor the evolution of host resistance, but hosts typically face a trade-off between investment in reproductive fitness and investment in defense against parasites. the magnitude of such a trade-off is likely to be context-dependent, and accordingly costs that are key in shaping evolution in nature ma ...	2015	25809535
jasmonate signalling in arabidopsis involves sgt1b-hsp70-hsp90 chaperone complexes.	plant hormones play pivotal roles in growth, development and stress responses. although it is essential to our understanding of hormone signalling, how plants maintain a steady state level of hormone receptors is poorly understood. we show that mutation of the arabidopsis thaliana co-chaperone sgt1b impairs responses to the plant hormones jasmonate, auxin and gibberellic acid, but not brassinolide and abscisic acid, and that sgt1b and its homologue sgt1a are involved in maintaining the steady st ...	2015	27054042
the pseudomonas aeruginosa pa14 abc transporter nppa1a2bcd is required for uptake of peptidyl nucleoside antibiotics.	analysis of the genome sequence of pseudomonas aeruginosa pa14 revealed the presence of an operon encoding an abc-type transporter (nppa1a2bcd) showing homology to the yej transporter of escherichia coli. the yej transporter is involved in the uptake of the peptide-nucleotide antibiotic microcin c, a translation inhibitor that targets the enzyme aspartyl-trna synthetase. furthermore, it was recently shown that the opp transporter from p. aeruginosa pao1, which is identical to npp, is required fo ...	2015	25917903
the divergent roles of staygreen (sgr) homologs in chlorophyll degradation.	degradation of chlorophyll (chl) by chl catabolic enzymes (cces) causes the loss of green color that typically occurs during senescence of leaves. in addition to cces, staygreen1 (sgr1) functions as a key regulator of chl degradation. although sgr1 mutants in many plant species exhibit a stay-green phenotype, the biochemical function of the sgr1 protein remains elusive. many recent studies have examined the physiological and molecular roles of sgr1 and its homologs (sgr2 and sgr-like) in chl met ...	2015	25913011
deficient plastidic fatty acid synthesis triggers cell death by modulating mitochondrial reactive oxygen species.	programmed cell death (pcd) is of fundamental importance to development and defense in animals and plants. in plants, a well-recognized form of pcd is hypersensitive response (hr) triggered by pathogens, which involves the generation of reactive oxygen species (ros) and other signaling molecules. while the mitochondrion is a master regulator of pcd in animals, the chloroplast is known to regulate pcd in plants. arabidopsis mosaic death 1 (mod1), an enoyl-acyl carrier protein (acp) reductase esse ...	2015	25906995
early response to nanoparticles in the arabidopsis transcriptome compromises plant defence and root-hair development through salicylic acid signalling.	the impact of nano-scaled materials on photosynthetic organisms needs to be evaluated. plants represent the largest interface between the environment and biosphere, so understanding how nanoparticles affect them is especially relevant for environmental assessments. nanotoxicology studies in plants allude to quantum size effects and other properties specific of the nano-stage to explain increased toxicity respect to bulk compounds. however, gene expression profiles after exposure to nanoparticles ...	2015	25903678
