Dirigent (DIR) and DIR-like family genes were involved in lignification or in the response to pathogen infection and abiotic stress in plants. Little is known to us about how rice DIR genes respond to adverse conditions. In this study, we reported genome-wide analysis of 49 DIR or DIR-likes genes in rice. The 49 OsDIRs or OsDIR-likes were tandem arranged into ten clusters. The phylogenetic analysis indicated that the 49 rice DIR and DIR-like genes cluster into five distinct subfamilies, DIR-a and four DIRlike subfamilies (DIR-b/d, and DIR-g, DIR-c, DIR-e). Meta-analysis of microarray gene expression datas indicated that all the OsDIRs or OsDIR-likes were expressed almost at the same level but with different patterns: most OsDIRs or OsDIR-likes were expressed exclusively in stigma and ovary and were induced by IAA and BAP; several genes were induced by trans-zeatin (tZ) and DMSO; 23 OsDIRs or OsDIR-likes were responded to abiotic stress. Our analysis also showed that most of these genes could respond to abiotic stresses, which contained cis-regulatory elements. The present study will provide a useful reference for further functional analysis of the DIR genes in rice.

Dose the blackened lubrication oil needs to be replaced forflying safety? Since there is very limited roomfor inaccurate assessment of oil quality due to strictflying safety standards, much aviation lubrication oilis disposed in advance long before their service life. More important, aircrafts still face the fatalchallenges from unpredictable lubrication oil deterioration. Color change is surely a significant signal to diagnose the quality of lubrication oils. Based on thecolorimeter, the color numbers of the testing lubrication oils are measured in this paper to identify thecolor variation degree of the oxidized lubrication oils. Then the molecular structures of the oxidizedlubrication oils are investigated tofind the intrinsic relationship between the oxidation products andcolor numbers. Based on key performances of the oxidized oil samples, the oil quality is undoubtfullydeteriorated which is coincident with the variation of color number. The color numbers of the usedaviation lubrication oils could provide an alternative way to readily and quickly measure the declinedegree and residual lifetime.
