NaCl- and cold-induced stress activate different Ca²⁺-permeable channels in Arabidopsis thaliana

Chao Wang, Yibo Teng, Shan Zhu, Linlin Zhang, more

Plant Growth Regulation > 2019 > 87 > 2 > 217-225

Salinity (NaCl) and low temperatures significantly affect plant growth, development, and agricultural productivity. Both these stresses trigger an increase in free cytosolic Ca²⁺ concentration ([Ca²⁺]_i) via Ca²⁺ influx across the plasma membrane. However, the interaction between salinity- and low temperature-induced [Ca²⁺]_i increases are still poorly understood. We used aequorin to investigate the...

Nitrate reductase is regulated by CIRCADIAN CLOCK-ASSOCIATED1 in Arabidopsis thaliana

Yibo Teng, Haoqiang Cui, Mengyun Wang, Xunyan Liu

Plant and Soil > 2017 > 416 > 1-2 > 477-485

Background and aims Nitrate reductase (NR) is highly conserved among plants and has an important role in plant nitrate assimilation pathway. Previous studies show that NR is regulated by circadian clock. However, the molecular mechanism remained elusive. In this study, we tried to find the central circadian clock component which is involved in transcriptional regulation of NR genes, NIA1 and NIA2...

Heterologous Expression and Functional Analysis of Rice GLUTAMATE RECEPTOR-LIKE Family Indicates its Role in Glutamate Triggered Calcium Flux in Rice Roots

Jun Ni, Zhiming Yu, Guankui Du, Yanyan Zhang, more

Rice > 2016 > 9 > 1 > 1-14

Background Tremendous progress has been made in understanding the functions of the GLUTAMATE RECEPTOR-LIKE (GLR) family in Arabidopsis. Still, the functions of OsGLRs in rice, especially the ion channel activities, are largely unknown. Results Using the aequorin-based luminescence imaging system, we screened the specificity of amino acids involved in the induction of Ca²⁺ flux in rice roots. Of...

The nitrate transporter NRT1.1 is involved in iron deficiency responses in Arabidopsis

Xunyan Liu, Haoqiang Cui, Anna Li, Ming Zhang, more

Journal of Plant Nutrition and Soil Science > 178 > 4 > 601 - 608

Iron (Fe) deficiency strongly induces Fe‐acquisition gene expression. The nitrate transporter NRT1.1, which functions as a dual‐affinity nitrate transporter and nitrate signaling sensor, is involved in many nitrate‐dependent responses. However, the regulation of plant responses to Fe deficiency by NRT1.1 has not been described. In this study, it is shown that NRT1.1 is down‐regulated by Fe deficiency...

Identification of miRNAs associated with dark-induced senescence in Arabidopsis

Xiaoying Huo, Chao Wang, Yibo Teng, Xunyan Liu

BMC Plant Biology > 2015 > 15 > 1 > 1-12

Background microRNAs (miRNAs) are endogenous small (~21 nucleotide) single-stranded non-coding RNAs that typically function by guiding cleavage of target genes. To find the miRNAs that may be involved in dark-induced leaf senescence, we identified miRNAs by microarray platform using Arabidopsis thaliana leaves from both whole darkened plants (DPs) and individually darkened leaves (IDLs). Results...

Reduced expression of CTR1 gene modulated by mitochondria causes enhanced ethylene response in cytoplasmic male‐sterile Brassica juncea

Xunyan Liu, Xiaodong Yang, Xuan Zhao, Jinghua Yang, more

Physiologia Plantarum > 145 > 2 > 332 - 340

We studied how mitochondria affect ethylene response via modulation of CTR1 expression in cytoplasmic male‐sterile (CMS) Brassica juncea. The expression of CTR1 gene was reduced in CMS compared with male‐fertile (MF) lines. We observed that hypocotyl and root lengths were shorter than in the MF line during germination in the dark. An enhanced ethylene response was observed in CMS plants as shown by...

Percutaneous coagulation therapy of hepatocellular carcinoma by combining microwave coagulation therapy and ethanol injection

Ping Zhou, Xunyan Liu, Ruizhen Li, Wanping Nie

European Journal of Radiology > 2009 > 71 > 2 > 338-342

To determine if larger hepatocellular carcinoma (HCC) coagulation volumes can be obtained by combining percutaneous microwave coagulation therapy (PMCT) and ethanol injection (PEI) or PEI followed by PMCT with occlusion of the feeding artery.Eighty patients with 88 HCCs were treated with (I) PMCT; (II) combined therapy of PEI immediately followed by PMCT; (III) combined therapy of PEI immediately...
