Off topic:Appending strings to fasta header from another file

Question

[Ming]

Hello there,

I have a A.fasta file containing:

>AAL09996.1
ATGTCTAGCAAGCCGTCGAATATGCTTGATGAAGTTACCCTGTATACTCACTACGGCCTATCCGTGGCGAAGAAGCTCGGTGCGAATATGGTCGATGCTTTCCGGTCGGCCTTTTCGGTCAATGATGACATTCGTCAGGTGTATTACCGCGACAAGGGCATCTCTCACGCCAAAGCCGGTCGTTATTCCGAGGCAGTGGTGATGCTCGAGCAGGTTTACGATGCCGATGCCTTCGACGTGGAAGTGGCGCTGCATTTGGGAATCGCCTACGTTAAGACCGGGGCCGTTGATCGCGGCACCGAGTTGCTTGAGCGCTCCATCGCCGATGCGCCTGACAACATCAAGGTCGCGACCGTCCTTGGCCTGACCTATGTGCAGGTGCAAAAATATGATTTGGCCGTGCCTCTACTGGTCAAGGTGGCGGAAGCCAATCCGGTGAATTTCAATGTCCGCTTCCGTCTCGGGGTGGCGCTGGATAATCTGGGCCGCTTTGACGAAGCCATCGACAGTTTCAAGATCGCTTTGGGGCTGCGTCCCAATGAAGGCAAGGTGCATCGCGCAATCGCGTACAGCTACGAGCAGATGGGCTCGCACGAAGAGGCTTTGCCGCATTTTAAGAAGGCCAATGAACTCGATGAACGTTCGGCCGTCTAA

...

I also have another file, A.taxonomy:

AAL09996.1  Bacteria;Proteobacteria;Alphaproteobacteria;Rhodospirillales;Rhodospirillaceae;Magnetospirillum;Magnetospirillum gryphiswaldense
AAR90856.1  Bacteria;Proteobacteria;Alphaproteobacteria;Rhodospirillales;Rhodospirillaceae;Magnetospirillum;Magnetospirillum magnetotacticum

etc etc

How do I modify the fasta headers so that it appears like this:

>AAL09996.1 Bacteria;Proteobacteria;Alphaproteobacteria;Rhodospirillales;Rhodospirillaceae;Magnetospirillum;Magnetospirillum gryphiswaldense
ATGTCTAGCAAGCCGTCGAATATGCTTGATGAAGTTACCCTGTATACTCACTACGGCCTATCCGTGGCGAAGAAGCTCGGTGCGAATATGGTCGATGCTTTCCGGTCGGCCTTTTCGGTCAATGATGACATTCGTCAGGTGTATTACCGCGACAAGGGCATCTCTCACGCCAAAGCCGGTCGTTATTCCGAGGCAGTGGTGATGCTCGAGCAGGTTTACGATGCCGATGCCTTCGACGTGGAAGTGGCGCTGCATTTGGGAATCGCCTACGTTAAGACCGGGGCCGTTGATCGCGGCACCGAGTTGCTTGAGCGCTCCATCGCCGATGCGCCTGACAACATCAAGGTCGCGACCGTCCTTGGCCTGACCTATGTGCAGGTGCAAAAATATGATTTGGCCGTGCCTCTACTGGTCAAGGTGGCGGAAGCCAATCCGGTGAATTTCAATGTCCGCTTCCGTCTCGGGGTGGCGCTGGATAATCTGGGCCGCTTTGACGAAGCCATCGACAGTTTCAAGATCGCTTTGGGGCTGCGTCCCAATGAAGGCAAGGTGCATCGCGCAATCGCGTACAGCTACGAGCAGATGGGCTCGCACGAAGAGGCTTTGCCGCATTTTAAGAAGGCCAATGAACTCGATGAACGTTCGGCCGTCTAA

The headers will be joined together by a tab.

Thank you and will be appreciate any help.
