Aegilops tauchii, which is the ancestor of the common wheat, has abundant genetic variation, but the volume of production and quality of Qinghai–Tibet Plateau wheat are not good because of the local special climate. Different processing conditions were used to find the Aegilops tauschii accessions that adapted to the climate of the Qinghai–Tibet Plateau, and we have selected 57 Aegilops tauchii accessions that can succeed in this climate. The current situation of common wheat in Qinghai–Tibet Plateau can benefit from these results.

As a polygenic stress, drought poses one of the major threats to crop yields in agriculture. Advances in sequencing technology have shown that long non-coding RNAs (lncRNAs) play important roles in plant growth and stress responses. Differential expression analysis showed 310 differentially expressed lincRNAs (DE-lincRNAs). Functional enrichment annotation and quantitative reverse transcription polymerase chain reaction analyses were employed to explore the regulatory responses of lincRNAs during drought stress, which is important for the breeding of drought-resistant wheat varieties.
