GUS activity analysis of the GhWRKY42 promoter. a Detection of the GUS activity of the GhWRKY42 promoter deletion vector transiently expressed in Nicotiana tabacum. From the left to right, the pBI121 vector (positive control) and the ProGhWRKY42::GUS (− 1943 bp to − 1 bp), ProGhWRKY42–1::GUS (− 1407 bp to − 1 bp), ProGhWRKY42–2::GUS (− 778 bp to − 1 bp) and ProGhWRKY42–3::GUS (− 391 bp to − 1 bp) constructs are shown. (b) GUS activity of ProGhWRKY42::GUS transgenic Arabidopsis in different tissues. (a-e) roots, stems, leaves, floral organs and pods
