CmPYL7 positively regulates the cold tolerance via interacting with CmPP2C24-like in oriental melon.

Pyrabactin or Actin Resistance1/PYR1-Like/Regulatory Components of abscisic acid (ABA) Receptors (PYR/PYL/RCARs, referred to as PYLs) are direct receptors of ABA that function pivotally in the ABA-signaling pathway. Previously, we discovered that CmPYL7 was strongly upregulated by cold stress in oriental melon (Cucumis melo). In this study, we demonstrated that CmPYL7 was strongly induced by cold treatment (Cold), Cold+ABA, and Cold+fluridone (Flu, an ABA inhibitor) treatments, while the expression level of CmPYL7 under Cold+Flu is lower than that of cold treatment.

Herein, a dual-emission Eu metal-organic framework (Eu-MOF) is prepared and used as the ratiometric fluorescence probe for ultrasensitive detection of aminoglycoside antibiotics (AGs). Due to the strong hydrogen bond interactions between AGs and Eu-MOF, the blue emission is enhanced while the red emission has little fluctuation in Eu-MOF with the addition of AGs, thus a good linear relationship with the logarithm of AGs concentrations from 0.001 to 100 μg/mL can be established for quantitative analysis.
