General Information and FAQ

HeliantHOME, is a curated, public and dynamic database, where we have assembled a comprehensive and unique dataset of phenotypes including developmental, structural, environmental and experimental traits, for a large collection of both wild and cultivated Sunflowers, coupled with its genotypic data. HeliantHOME provides a centralized platform for the scientific community interested in diverse disciplines (within or not the sunflower field) from basic sciences (evolutionary biology, ecology, comparative genomics and even computational scientists and machine learning) to more applied sciences (including the agricultural sector both public and private ones).

Data corresponding to the wild populations, is for now, only coming from a large garden experiment carried out at UBC, Vancouver Campus, BC, Canada in 2016 (Todesco et al., 2020). Data corresponding to the cultivated accessions, comes from multiple different studies carried out both in Canada and the US, using an association mapping population, so-called SAM population.

The SAM population is a subset of 288 accessions, from collections held by both the USDA North Central Regional Plant Introduction Station (NCRPIS) and the French National Institute for Agricultural Research (INRA). These accessions include numerous inbred lines, important open-pollinated varieties (including high-oil Eastern European cultivars) as well as oilseed and confectionery (non-oil) accessions from elsewhere in the world. (Mandel et al, 2011, 2013).

All data from this database and additional genotypic data and GWAS results can be downloaded in the download section of this website: Download Center

Alternatively, all data can be downloaded using the REST API from HeliantHOME. All REST endpoints can be found in the following documentation of the REST API. The REST API provides a flexible way to download certain data from the database using standard URLs.

All data are archived in the digital library of the Technical University of Munich under the following DOI:
