Gene Details:

• Gene ID: MD08G1130200
• Gene Symbol: MxHA2
• Gene Name: plasma membrane (PM) H+-ATPase
• Genome:
• Species: Malus xiaojinensis

Functional Descriptions:

• MxMPK6-2-mediated phosphorylation enhances the response of apple rootstocks to Fe deficiency by activating PM H+-ATPase MxHA2.
• The plasma membrane (PM) H+-ATPase MxHA2 promoted H+ secretion and root acidification of apple rootstocks under Fe deficiency stress.
• H+-ATPase MxHA2 is upregulated in Fe-efficient apple rootstock of Malus xiaojinensis at the transcription level. Fe deficiency also induced kinase MxMPK6-2, a positive regulator in Fe absorption that can interact with MxHA2.
• The MAP kinase MxMPK6-2-mediated phosphorylation directly and indirectly regulates PM H+-ATPase MxHA2 activity at the protein post-translation and transcription levels, thus synergistically enhancing root acidification under Fe deficiency stress.
• MxHA2 positively regulates the response of apple rootstocks to Fe deficiency stress.
