OK, so it is not possible from a fasta file but it is possible from a GB file. Fair enough, thank you! For matter of completion, I could not produce a GB file for the taxon 10239: when i ran the command

esearch -db "nucleotide" -query "txid10239[Organism] AND refseq[filter]"|efetch -format gb > genome.gb

I got:

500 read timeout
No do_post output returned from 'https://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=nucleotide&term=txid10239%5BOrganism%5D%20AND%20refseq%5Bfilter%5D&retmax=0&usehistory=y&edirect=7.00&tool=edirect&email=gigiux@DirtyHarry'
