Natural variations in the P-type ATPase heavy metal transporter gene ZmHMA3 control cadmium accumulation in maize grains

Journal of Experimental Botany (2021)

Bin Tang Meijie Luo Yunxia Zhang Huanle Guo Jingna Li

Abstract Cadmium (Cd) accumulation in maize grains is detrimental to human health. Developing maize varieties with low Cd content is important for safe consumption of maize grains. However, the key genes controlling maize grain Cd accumulation have not been cloned. Here, we identified one major locus for maize grain Cd accumulation (qCd1) using a genome-wide association study (GWAS) and bulked segregant RNA-seq analysis with a biparental segregating population of Jing724 (low-Cd line) and Mo17 (high-Cd line). The candidate gene ZmHMA3 was identified by fine mapping and encodes a tonoplast-localized heavy metal P-type ATPase transporter. An ethyl methane sulfonate mutant analysis and an allelism test confirmed that ZmHMA3 influences maize grain Cd accumulation. A transposon in intron 1 of ZmHMA3 is responsible for the abnormal amino acid sequence in Mo17. Based on the natural sequence variations in the ZmHMA3 gene of diverse maize lines, four PCR-based molecular markers were developed, and these were successfully used to distinguish five haplotypes with different grain Cd contents in the GWAS panel and to predict grain Cd contents of widely used maize inbred lines and hybrids. These molecular markers can be used to breed elite maize varieties with low grain Cd contents.

Study on involvement of the GTPase RABE1b in embryonic development of Arabidopsis thaliana.

Liyuan Ma Xiaoduo Lu Shen Songdong Chunyi Zhang

[Objective] The aim was to study the gene affecting division mode in the early embryonic development of Arabidopsis thaliana.[Method] In this study,two T-DNA insertion mutants were isolated from the mutant library of A.thaliana inserted by T-DNA,and the embryonic development was refeleted by phenotypes.[Result] Genomic PCR-WALKING analyses demonstrated that T-DNA insertion sites were in 5′ non-coding region and promoter region of gene At4g20360 which encode Rab GTPase RABE1b,and the two mutants were named as Atrabe1b-1 and Atrabe1b-2,respectively.Microscopic analysis on mutants revealed that there was an abnormal cell division pattern in early globular stage of embryonic development.In addition,RT-PCR analysis showed that gene At4g20360 was constitutively expressed in A.thaliana.[Conclusion] Gene At4g20360 affected the division pattern of early embryonic development in A.thaliana,and encoded protein GTPase RABE1b which may play an important role in cell division during embryonic development of A.thaliana.

FtsHi4 Is Essential for Embryogenesis Due to Its Influence on Chloroplast Development in Arabidopsis

PLoS ONE (2014)

Xiaoduo Lu Dongyuan Zhang Shipeng Li Yanping Su Qiuju Liang

Chloroplast formation is associated with embryo development and seedling growth. However, the relationship between chloroplast differentiation and embryo development remains unclear. Five FtsHi genes that encode proteins with high similarity to FtsH proteins, but lack Zn2+-binding motifs, are present in the Arabidopsis genome. In this study, we showed that T-DNA insertion mutations in the Arabidopsis FtsHi4 gene resulted in embryo arrest at the globular-to-heart–shaped transition stage. Transmission electron microscopic analyses revealed abnormal plastid differentiation with a severe defect in thylakoid formation in the mutant embryos. Immunocytological studies demonstrated that FtsHi4 localized in chloroplasts as a thylakoid membrane-associated protein, supporting its essential role in thylakoid membrane formation. We further showed that FtsHi4 forms protein complexes, and that there was a significant reduction in the accumulation of D2 and PsbO (two photosystem II proteins) in mutant ovules. The role of FtsHi4 in chloroplast development was confirmed using an RNA-interfering approach. Additionally, mutations in other FtsHi genes including FtsHi1, FtsHi2, and FtsHi5 caused phenotypic abnormalities similar to ftshi4 with respect to plastid differentiation during embryogenesis. Taken together, our data suggest that FtsHi4, together with FtsHi1, FtsHi2, and FtsHi5 are essential for chloroplast development in Arabidopsis.

ZmXYL modulates auxin‐induced maize growth

The Plant Journal (2023)

Haiyan Li Huifang Tao Yao Xiao Qin Li Chen Lan

Plant architecture, lodging resistance, and yield are closely associated with height. In this paper, we report the identification and characterization of two allelic EMS-induced mutants of Zea mays, xyl-1, and xyl-2 that display dwarf phenotypes. The mutated gene, ZmXYL, encodes an α-xylosidase which functions in releasing xylosyl residue from a β-1,4-linked glucan chain. Total α-xylosidase activity in the two alleles is significantly decreased compared to wild-type plants. Loss-of-function mutants of ZmXYL resulted in a decreased xylose content, an increased XXXG content in xyloglucan (XyG), and a reduced auxin content. We show that auxin has an antagonistic effect with XXXG in promoting cell divisions within mesocotyl tissue. xyl-1 and xyl-2 were less sensitive to IAA compared to B73. Based on our study, a model is proposed that places XXXG, an oligosaccharide derived from XyG and the substrate of ZmXYL, as having a negative impact on auxin homeostasis resulting in the dwarf phenotypes of the xyl mutants. Our results provide a insight into the roles of oligosaccharides released from plant cell walls as signals in mediating plant growth and development.

In Fig 7B of this article [1], the PsbO data were duplicated in error as representing the Cyt f results.In the updated figure provided here, the Cyt f panel has been replaced with the correct image from the original experiment.The original uncropped blot images supporting Fig 7B are provided in Supporting Information S1-S6 Files of this notice.A member of PLOS ONE's Editorial Board confirmed that the updated figure supports the results as reported in the original article.In addition, details as to the antibodies used for western blot experiments were not reported in the Material and Methods section.The antibodies used to detect the D1, D2, CP43, PsbO and Cyt f proteins were kindly provided by Dr. Lixin Zhang (College of Life Science, Henan University), and the details of those antibodies were described in a previous study [2].The polyclonal antibody against FtsHi4 was raised in rabbits using the synthetic oligopeptide of SETSGRVFARKSDY, a part of the FtsHi4 protein.Specificity of the antibody was verified by the absence of FtsHi4 protein expression in the ftshi4 mutant (Figure 5 of [1]).Except for the image data provided here in support of Fig 7B, the raw data underlying results reported in this article [1] are no longer available.
