In the original publication of the article [1], a few errors were identified.

In the Materials and methods section, under the subheading “Immature embryos isolation”, the term 0.44 mg L−1 should read as 0.44 g L−1.

Under the subheading, “Resting period, callus induction and selection of transformed material” the term 5 mg L−1 and 15 mg mL−1 should read as 5 g L−1 and 15 mg L−1.

Under the subheading “Regeneration of transgenic plants” the term 20 mg L−1 and 0.5 mg L−1 should read as 20 g L−1 and 0.5 g L−1 .

In the Results section, under the subheading “Optimization of wheat transformation with Agrobacterium Effect of gelling agent on callus induction and regeneration”, the term 2%, 5%, 3.5% and 8% should read as 0.2%, 0.5%, 0.35% and 0.8%.
