SNPversity: a web based tool for visualizing diversity

PMCID: 5912076
PMID: 29688387
DOI: 10.1093/database/bay037

[…] With low-cost genomic technologies, increasingly more data are available to biologists, and online biological databases, such as MaizeGDB () and GrainGenes (), are being challenged by the diversity of data types that need to be curated, managed, queried, and visualized. For some data types, web-based software applications are a […]


Massive Loss of DNA Methylation in Nitrogen , but Not in Phosphorus Deficient Zea mays Roots Is Poorly Correlated With Gene Expression Differences

Front Plant Sci
PMCID: 5917015
PMID: 29725341
DOI: 10.3389/fpls.2018.00497

[…] irst 4 and the last 6 basepairs of each read were then removed via the FastX-Toolkit by Hannon Lab to remove bias and get higher quality reads. As reference the Z. mays genome (AGPv3) provided by the Maize Genetics and Genomics Database () was used. The alignment was done by BS-Seeker2, which produces a reduced representation genome from the reference genome to increase mappability and accuracy of […]


Long Non Coding RNAs Responsive to Salt and Boron Stress in the Hyper Arid Lluteño Maize from Atacama Desert

PMCID: 5867891
PMID: 29558449
DOI: 10.3390/genes9030170

[…] o identify the relationship of Lluteño maize with other commercial variants, we performed different sequence similarity searches against the genomic sequences from maize with genome data available at MaizeGDB []. For B73, the most used and completely sequenced maize variant, we used the genome assembly release RefGen_v3. For Palomero, we used the assembly version v1, containing 196,697 contigs. Fo […]


Map based cloning and characterization of Zea mays male sterility33 (ZmMs33) gene, encoding a glycerol 3 phosphate acyltransferase

PMCID: 5945757
PMID: 29546443
DOI: 10.1007/s00122-018-3083-9

[…] To elucidate the evolutionary relationship between ZmMs33 and its close homologues, the ZmMs33 protein sequence was used in BLASTP queries in NCBI, MaizeGDB and RGAP databases. Meanwhile, we used AtATS1 and AtGPAT9 protein sequences to search for the putative sn-1 GPATs in maize and rice. Consequently, there are 18 and 20 putative GPATs in the ma […]


Evaluation of Optimized Tube Gel Methods of Sample Preparation for Large Scale Plant Proteomics

PMCID: 5874765
PMID: 29385730
DOI: 10.3390/proteomes6010006
call_split See protocol

[…] Data were searched with X!Tandem (version 2015.04.01.1 []) against the maize genome database V5a ( and a homemade database containing standard contaminants. Trypsin digestion was set in strict mode with one authorized missed cleavage. Cysteine carbamidomethylation was se […]


Genome wide association analysis and QTL mapping reveal the genetic control of cadmium accumulation in maize leaf

BMC Genomics
PMCID: 5785805
PMID: 29370753
DOI: 10.1186/s12864-017-4395-x

[…] Expression profiles of eight candidate genes were examined in maize B73 under non-limiting growth conditions. Using online transcriptome data from maize B73 (MaizeGDB), an expression heatmap was constructed for these candidate genes in different tissues from 8 developmental stages (Fig. ). The results showed that the expression patterns of different candid […]
