Awns are bristle-like structures, typically extending from the tip end of the lemmas in the florets of cereal species, including such economically important crops as wheat (Triticum aestivum L., T. durum Desf.

- The study focuses on a liguleless mutant of Aegilops tauschii, highlighting the significance of the ligule in leaf development and plant structure.
- Researchers mapped the Lg gene responsible for this trait to chromosome 5DS using advanced genetic mapping techniques, identifying its role in controlling leaf patterning.
- This research provides new insights into genetic control of leaf features in cereal species, marking the first report of a dominant liguleless trait in the Triticeae family.
Background: Inflorescences of wheat species, spikes, are characteristically unbranched and bear one sessile spikelet at a spike rachis node. Development of supernumerary spikelets (SSs) at rachis nodes or on the extended rachillas is abnormal. Various wheat morphotypes with altered spike morphology, associated with the development of SSs, present an important genetic resource for studies on genetic regulation of wheat inflorescence development.
