摘要

This study deals with the characterisation of early responses of roots of Salix matsudana in respect to oxidative stress, subcellular distribution, and chemical forms when exposed to 50 mol/L Cd. Within 12 h, the root length is reduced and the contents of O-2(center dot-), H2O2, and malondialdehyde are increased by 49%, 43%, and 35%. Cd is mainly retained in the cell walls; small amounts are distributed into other cell organelles. The largest proportion of Cd is found in the NaCl extractable, pectate-, and protein-integrated fraction.

Molecular responses to salinity stress in Salix matsudana (Koidz) females and males

Guoyuan Liu, Yuqing Wang, Bolin Lian, Ziqi Ma, Xiaoting Xiang, Jing Wu, Chunying Luo, Duojin Ma, Yanhong Chen, Chunmei Yu, Fei Zhong, Hui Wei, Jian Zhang

Summary: Sexual dimorphism is common in many species. Salix matsudana males and females exhibit different phenotypes under salinity stress, with males having stronger roots and heavier dry weights. Analysis of the root transcriptome revealed unique molecular mechanisms of males and females under salinity stress. Males up-regulated abiotic stress response genes to adjust to salinity stress, while females down-regulated nitrogen metabolism-related genes to decrease harm. Understanding the salinity tolerance in Salix matsudana males and females provides insights into sexual dimorphism and benefits the ecological environment.

Transcription factor ANAC004 enhances Cd tolerance in Arabidopsis thaliana by regulating cell wall fixation, translocation and vacuolar detoxification of Cd, ABA accumulation and antioxidant capacity

Yu Ting Meng, Xiao Long Zhang, Qi Wu, Ren Fang Shen, Xiao Fang Zhu

Summary: In this study, researchers identified a nucleus-localized transcription factor, ANAC004, which is involved in regulating cadmium (Cd) resistance in Arabidopsis plants. ANAC004 enhances cell wall Cd immobilization, increases vacuolar Cd detoxification, and inhibits Cd translocation, thus improving Cd resistance. These processes may be mediated by ABA signaling and antioxidant defense systems.

Genome-wide characterization and identification of Trihelix transcription factors and expression profiling in response to abiotic stresses in Chinese Willow (Salix matsudana Koidz)

Jie Yang, Zhixuan Tang, Wuyue Yang, Qianhui Huang, Yuqing Wang, Mengfan Huang, Hui Wei, Guoyuan Liu, Bolin Lian, Yanhong Chen, Jian Zhang

Summary: In this study, the Trihelix gene family was analyzed in Salix matsudana, an ornamental forest tree. A total of 78 Trihelix transcription factors were identified and classified into four subfamilies. The expression pattern analysis revealed that these genes play different roles in response to flooding stress, with SmTTF30 showing enhanced tolerance to flooding stress when overexpressed in Arabidopsis thaliana.

Identify of Fast-Growing Related Genes Especially in Height Growth by Combining QTL Analysis and Transcriptome in Salix matsudana (Koidz)

Guoyuan Liu, Qingshan Yang, Junfeng Gao, Yuwei Wu, Zhicong Feng, Jingke Huang, Hang Zou, Xingzhao Zhu, Yanhong Chen, Chunmei Yu, Bolin Lian, Fei Zhong, Jian Zhang

Summary: The study focused on the fast-growing traits of trees, specifically tree height (TH) and diameter at breast height (DBH), using a high-density genetic map to identify genetic regions for these traits. Six stable QTL related to fast-growing traits were identified on six chromosomes, and candidate genes regulating height growth were discovered. This research lays a strong foundation for further exploration of the molecular and genetic regulation of TH and DBH.

SaMT3 in Sedum alfredii drives Cd detoxification by chelation and ROS-scavenging via Cys residues

Jianqi Zhao, Ruohan Xie, Jiayu Lin, Lingling Xu, Xiaoyu Gao, Xianyong Lin, Shengke Tian, Lingli Lu

Summary: This study functionally characterized SaMT3 in the Cd/Zn hyperaccumulator S. alfredii. The C- and N-terminal regions of SaMT3 exhibited differential functional roles in Cd adaptation, with the C-terminal region involved in Cd sensing and binding and the N-terminal region responsible for ROS scavenging. Overexpression of SaMT3 increased Cd tolerance in transgenic plants, while knockout of SaMT3 led to decreased Cd concentrations and increased ROS levels. These findings provide valuable insights into the role of SaMT3 in Cd hyperaccumulation and the molecular mechanisms underlying Cd detoxification in plants.

Insights into the isotopic mismatch between bulk soil water and Salix matsudana Koidz trunk water from root water stable isotope measurements

Ying Zhao, Li Wang

Summary: Increasing field studies have found isotopic mismatches between plant trunk water and its sources. The cause of these offsets is unclear, but may be related to soil water heterogeneity. This study shows that root water isotopic composition deviates from bulk soil water, and trunk water is only isotopically similar to root water at specific depths.

Isotopically Light Cd in Sediments Underlying Oxygen Deficient Zones

Lena Chen, Susan H. Little, Katharina Kreissig, Silke Severmann, James McManus

Summary: Cadmium is a trace metal in the ocean that mimics phosphate concentration, but deviations occur in oxygen deficient zones. Organic-rich sediments have light Cd isotope compositions, suggesting a light source of Cd, yet the application of Cd isotopes as a paleoproductivity proxy is complex due to multiple possible sources and processes in the water column.

Ca alleviated Cd-induced toxicity in Salix matsudana by affecting Cd absorption, translocation, subcellular distribution, and chemical forms

Jinhua Zou, Yuerui Wang, Siyuan Wang, Xiaoshuo Shang

Summary: Adding calcium can alleviate the toxic effects of Cd on S. matsudana seedlings by reducing Cd absorption and promoting its translocation. It also changes the subcellular distribution and chemical forms of Cd. Moreover, genes related to Cd uptake and xylem loading are upregulated after Cd and Cd + Ca treatments. This study provides new insights into the role of calcium in reducing Cd toxicity and suggests its potential for improving phytoremediation of Cd contamination.

Mechanism of Zn alleviates Cd toxicity in mangrove plants (Kandelia obovata)

Shan Chen

Summary: This study found that zinc (Zn) has been used to reduce cadmium (Cd) accumulation in mangrove ecosystems in China. In a set of pot experiments, Cd-contaminated Kandelia obovata plants were treated with different concentrations of ZnSO4 to study the effects on biomass, Cd and Zn contents, phenolic acid metabolism, antioxidant capacity, chlorophyll, and soluble sugar contents in the leaves. The results showed that low-dose ZnSO4 treatment had positive effects on the various parameters analyzed, indicating that Zn alleviates Cd toxicity in mangrove plants through enhancing phenolic acid metabolism and antioxidant capacity.

Summary: By modulating cellular oxidative repair mechanisms, the use of biogenic silicon nanoparticles can alleviate cadmium stress in rapeseed plants. The treatment with these nanoparticles significantly improved growth parameters, photosynthetic efficiency, and antioxidant enzyme activities in rapeseed plants. Furthermore, the treatment also mitigated the damage caused by cadmium, altered gene expressions, and influenced metal accumulation in the plants.

Integrated transcriptome and metabonomic analysis of key metabolic pathways in response to cadmium stress in novel buckwheat and cultivated species

Dongao Huo, Ying Hao, Juan Zou, Lixia Qin, Chuangyun Wang, Dengxiang Du

Summary: Buckwheat is an important food crop with medicinal uses. This study analyzed the response of cultivated and perennial buckwheat species to cadmium (Cd) stress using transcriptome and metabolomic methods. The results showed that Cd stress affected reactive oxygen species and the chlorophyll system, and Cd-response genes related to stress response, amino acid metabolism, and ROS scavenging were enriched in the perennial species. Galactose, lipid metabolism, and glutathione metabolism were found to play important roles in the buckwheat response to Cd stress. These findings provide valuable insights into the molecular mechanisms underlying Cd tolerance in buckwheat and genetic improvement for drought tolerance.
