Wheat is one of the most popular cereal grain, taking up a large portion of
the total cultivated land. Since drought is considered as one of the major
sources of stress in plants, developing drought resistance trait while
maintaining favorable yield is important. A sunflower gene (HaHB4 or
Helianthus annuus homeobox 4) has been found to encode a transcription
factor linked to tolerating environmental stress. Thus, scientists from
Instituto de Agrobiotecnologia Rosario and Consejo Nacional de
Investigaciones Cientificas y Tecnicas in Argentina introduced HaHB4 in
wheat and analyzed its compositional equivalence with non-transgenic wheat.
The results are published in Transgenic Research.
The researchers analyzed 41 nutrients and 2 anti-nutrients for grain and 10
nutrients in forage through several tests. The findings showed that the
transgenic wheat (HB4 wheat or event IND-??412-7) is compositionally
equivalent to non-transgenic wheat.
