Enrichment of the bread wheat genome with new leaf pubescence genes from related species
Year: 2023

Leaf hairiness is an important adaptive trait as affects the leaf surface microclimate.Variability for this trait is found in common wheat.Three genes are known for today.The Hl1 gene located on 4B chromosome provides a dense layer of trichomes up to 150 m.The Hl2 gene located on 7B chromosome forms rare long trichomes more than 400 m.The predicted Hl3 gene forms a rare layer of short trichomes, mainly on the underside of the leaf.The wheat genome has been enriched with hairiness genes from vari
