TL;DR: A novel peptide, decoralin, was isolated from the venom of the solitary eumenine wasp Oreumenes decoratus and exhibited a significant broad-spectrum antimicrobial activity, and moderate mast cell degranulation and leishmanicidal activities, but showed virtually no hemolytic activity.

TL;DR: Four strains, isolated from nitrogen-fixing nodules on the roots of two species of Mimosa, Mimosa cordistipula and Mimosa misera, that are native to North East Brazil, and their taxonomic positions were investigated by using a polyphasic approach to represent a novel species in the genus Burkholderia.
Abstract: Four strains, designated JPY-345T, JPY-347, JPY-366 and JPY-581, were isolated from nitrogen-fixing nodules on the roots of two species of Mimosa, Mimosa cordistipula and Mimosa misera, that are native to North East Brazil, and their taxonomic positions were investigated by using a polyphasic approach. All four strains grew at 15–43 °C (optimum 35 °C), at pH 4–7 (optimum pH 5) and with 0–2 % (w/v) NaCl (optimum 0 % NaCl). On the basis of 16S rRNA gene sequence analysis, strain JPY-345T showed 97.3 % sequence similarity to the closest related species
Burkholderia soli
GP25-8T, 97.3 % sequence similarity to
Burkholderia caryophylli
ATCC25418T and 97.1 % sequence similarity to

KP23T. The predominant fatty acids of the strains were C18 : 1ω7c (36.1 %), C16 : 0 (19.8 %) and summed feature 3, comprising C16 : 1ω7c and/or C16 : 1ω6c (11.5 %). The major isoprenoid quinone was Q-8 and the DNA G+C content of the strains was 64.2–65.7 mol%. The polar lipid profile consisted of a mixture of phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol and several uncharacterized aminophospholipids and phospholipids. DNA–DNA hybridizations between the novel strain and recognized species of the genus

yielded relatedness values of <51.8 %. On the basis of 16S rRNA and recA gene sequence similarities and chemotaxonomic and phenotypic data, the four strains represent a novel species in the genus

TL;DR: Results suggest that CsNAC1 encodes a novel stress-responsive NAC transcription factor that is potentially useful for engineering tolerance to multiple abiotic stresses in citrus.
Abstract: The NAC (NAM, ATAF1, -2, and CUC2) gene family encodes a large family of plant-specific transcription factors that play diverse roles in plant development and stress regulation. In this study, we performed a survey of citrus NAC transcription factors in the HarvEST: Citrus database, in which 45 NAC domain-containing proteins were identified and phylogenetically classified into 13 different subfamilies. The results suggest the existence of a structurally diversified family of NAC transcription factors in citrus, which has not been previously characterized. One of these NAC genes, CsNAC1 was found to be a member of the stress-NAC subfamily, whose homologs from other plant species function in pathways of environmental stress response and tolerance, and was further characterized. The CsNAC1 deduced protein was shown to contain the five N-terminal A through E NAC subdomains, a C-terminal region containing three transcriptional activation motifs, and a predicted NAC nuclear localization signal, consistent with its putative role as a NAC transcription factor. In silico analysis indicated that CsNAC1 was primarily expressed in leaves and shoot meristems, and was involved in general stress responses. Quantitative real-time reverse transcription PCR analysis revealed that CsNAC1 was strongly induced by drought stress in leaves of Citrus reshni and Citrus limonia, and also by salt stress, cold, and ABA in leaves and roots of C. reshni. Collectively, these results suggest that CsNAC1 encodes a novel stress-responsive NAC transcription factor that is potentially useful for engineering tolerance to multiple abiotic stresses in citrus.

TL;DR: In this article, a 3D full-sphere supernova simulation of non-rotating low-mass progenitors is presented, covering the entire evolution from core collapse through bounce and shock revival, through shock breakout from the stellar surface, until fallback is completed several days later.
Abstract: We present 3D full-sphere supernova simulations of non-rotating low-mass (∼9 M_⊙) progenitors, covering the entire evolution from core collapse through bounce and shock revival, through shock breakout from the stellar surface, until fallback is completed several days later. We obtain low-energy explosions (∼0.5–1.0 × 10⁵⁰ erg) of iron-core progenitors at the low-mass end of the core-collapse supernova (LMCCSN) domain and compare to a super-AGB (sAGB) progenitor with an oxygen–neon–magnesium core that collapses and explodes as electron-capture supernova (ECSN). The onset of the explosion in the LMCCSN models is modelled self-consistently using the VERTEX-PROMETHEUS code, whereas the ECSN explosion is modelled using parametric neutrino transport in the PROMETHEUS-HOTB code, choosing different explosion energies in the range of previous self-consistent models. The sAGB and LMCCSN progenitors that share structural similarities have almost spherical explosions with little metal mixing into the hydrogen envelope. A LMCCSN with less second dredge-up results in a highly asymmetric explosion. It shows efficient mixing and dramatic shock deceleration in the extended hydrogen envelope. Both properties allow fast nickel plumes to catch up with the shock, leading to extreme shock deformation and aspherical shock breakout. Fallback masses of ≲ 5×10⁻³ M_⊙ have no significant effects on the neutron star (NS) masses and kicks. The anisotropic fallback carries considerable angular momentum, however, and determines the spin of the newly born NS. The LMCCSN model with less second dredge-up results in a hydrodynamic and neutrino-induced NS kick of >40 km s⁻¹ and a NS spin period of ∼30 ms, both not largely different from those of the Crab pulsar at birth.
