Jasmonate (JA) and ethylene (ET) are two major plant hormones that synergistically regulate development tolerance to necrotrophic fungi. Both JA ET induce the expression of several pathogenesis-related genes, while blocking either signaling pathway abolishes induction these genes by alone or in combination. However, molecular basis JA/ET coaction interdependency is largely unknown. Here, we report Arabidopsis ET-stabilized transcription factors (EIN3 EIL1) integrate regulation gene...

Abstract Background and Purpose Subarachnoid haemorrhage (SAH) is an uncommon severe subtype of stroke, but the availability drugs for its treatment limited. Enhanced autophagy believed to attenuate SAH pathology; however, level tentatively up‐regulated then down‐regulated after onset in mice. Clemastine, a first‐generation histamine H1R antagonist, persistently enhance autophagy. However, precise mechanism clemastine remains largely elusive. Experimental Approach Haemoglobin‐induced neuron...

We offer a practical unpaired learning based image dehazing network from an set of clear and hazy images. This paper provides new perspective to treat as two-class separated factor disentanglement task, i.e, the task-relevant reconstruction task-irrelevant haze-relevant distribution. To achieve these factors in deep feature space, contrastive is introduced into CycleGAN framework learn disentangled representations by guiding generated images be associated with latent factors. With such...
