Seeking chloroplast and mitochondrial reference for barley

Question

[IrK]

Dear Biostars community,

I am working with the plants Ensembl database for the Barley (Morex v3) genome. While I have all the necessary files (Fa, GTF), I couldn't locate any details regarding the barley chloroplast and mitochondrial genomes.

1. Although I found the Fasta file on NCBI GeneBank for Barley chloroplast genome I couldn't find a gene annotation file. Does such a file exist? Also, I'd prefer to have all genomes from the same database and Ensembl preferred by some tools I am using.
2. Additionally, is there any information available about the coordinates of repetitive regions?

thank you

In case it helps, the previous barley version at Ensembl Plants did contain organellar genomes, you can browse them at https://nov2020-plants.ensembl.org/Hordeum_vulgare/Info/Index?db=core

An example cp region can be see here: https://nov2020-plants.ensembl.org/Hordeum_vulgare/Location/View?db=core;r=Pt:7987-107987

RefSeq assembly for Morex v3 genome is supposed to contain chloroplast sequence: https://ftp.ncbi.nlm.nih.gov/genomes/all/GCF/904/849/725/GCF_904849725.1_MorexV3_pseudomolecules_assembly/. You will also find genome annotation files there.

Based on stats from the main genome page; https://www.ncbi.nlm.nih.gov/datasets/genome/GCF_904849725.1/

Sometimes getting the required information is very difficult

To find mitochondrial genome sequences and annotations, you can go to https://www.ncbi.nlm.nih.gov , select "Nucleotide" to the left of the search field and search for

"Hordeum vulgare" [organism] AND "mitochondrion" [title] AND "complete" [title]

You'll find a lot of assembled and annotated mitochondrial genomes of different samples of the barley.
The same you can do for the chloroplast genome, just replace "mitochondrion" with "chloroplast".
