Leaf rolling is crucial in wheat breeding as it enhances photosynthesis and yields, but research on the genetic basis of this trait in wheat is limited.
This study identified a rolling leaf mutant, T73, with specific traits that was created using chemical mutagenesis, revealing significant cellular changes that resulted in leaf rolling.
Genetic analysis pinpointed a single recessive gene linked to the rolling leaf trait on chromosome arm 1BL, with a specific point mutation affecting gene transcription implicated in the phenotype's development.
