Gene Details:

• Gene ID: TraesCS5D02G161000
• Gene Symbol: LYS3
• Gene Name: prolamin-box-binding transcription factor
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• LYS3 encodes a prolamin-box-binding transcription factor that controls embryo growth in barley and wheat.
• LYS3 encodes a transcription factor called Prolamin Binding Factor (PBF).
• PBF expression in wild-type embryos precedes the onset of embryo enlargement in LYS3 mutants, suggesting that PBF suppresses embryo growth.
• Mutations at the LYS3 locus in barley have multiple effects on grain development.
• Fine mapping LYS3 identified a 64-gene region on chromosome arm 5HL controlling embryo size.
• This showed that LYS3 mutant embryos were significantly larger than wild type embryos only after 23 DAF (Student’s t-test, p = 0.01). Thus, in wild-type embryos, the onset of PBF expression precedes the suppression of embryo growth.
