| 1 | IbNIEL-mediated degradation of IbNAC087 regulates jasmonic acid-dependent salt and drought tolerance in sweet potato显示文摘Sweet potato(Ipomoea batatas[L.]Lam.)is a crucial staple and bioenergy crop.Its abiotic stress tolerance holds significant importance in fully utilizing marginal lands.Transcriptional processes regulate abiotic stress responses,yet the molecular regulatory mechanisms in sweet potato remain unclear.In this study,a NAC(NAM,ATAF1/2,and CUC2)transcription factor,IbNAC087,was identified,which is commonly upregulated in salt-and drought-tolerant germplasms.Overexpression of IbNAC087 increased salt and drought tolerance by increasing jasmonic acid(JA)accumulation and activating reactive oxygen species(ROS)scavenging,whereas silencing this gene resulted in opposite phenotypes.JA-rich IbNAC087-OE(overexpression)plants exhibited more stomatal closure than wild-type(WT)and IbNAC087-Ri plants under NaCl,polyethylene glycol,and methyl jasmonate treatments.IbNAC087 functions as a nuclear transcriptional activator and directly activates the expression of the key JA biosynthesisrelated genes lipoxygenase(IbLOX)and allene oxide synthase(IbAOS).Moreover,IbNAC087 physically interacted with a RING-type E3 ubiquitin ligase NAC087-INTERACTING E3 LIGASE(IbNIEL),negatively regulating salt and drought tolerance in sweet potato.IbNIEL ubiquitinated IbNAC087 to promote 26S proteasome degradation,which weakened its activation on IbLOX and IbAOS.The findings provide insights into the mechanism underlying the IbNIEL-IbNAC087 module regulation of JA-dependent salt and drought response in sweet potato and provide candidate genes for improving abiotic stress tolerance in crops. | Xu Li Zhen Wang Sifan Sun Zhuoru Dai Jun Zhang Wenbin Wang Kui Peng Wenhao Geng Shuanghong Xia Qingchang Liu Hong Zhai Shaopei Gao Ning Zhao Feng Tian Huan Zhang Shaozhen He | 2024 | Journal of Integrative Plant Biology2024，66，2： | 0 |
| 2 | On the Consumption Structure of Rural Residents in Xi'an City Based on AIDS Model显示文摘Under the background of the financial crisis,expanding domestic demand for stimulating economic role is self-evident. As China has a large rural population,increasing rural residents' income and expanding their consumer demand is becoming the pinnacle of expanding domestic demand. The urban residents have good conditions than more countryside dwellers. Since few articles are dedicated to the research of this group,this article selects rural residents of Xi'an as object,uses AIDS model to analyze the consumption structure of rural residents,and draw the conclusion that increasing cultural recreation,medical and health spending is the main way to increase their incomes. | Shuanghong TANG Xianli XIA | 2015 | Asian Agricultural Research2015，7，1： | 0 |
