Gene Details:

• Gene ID: HORVU.MOREX.r3.4HG0384200
• Gene Symbol: Bmy2
• Gene Name: beta-amylase2
• Genome: MorexV3_pseudomolecules_assembly
• Species: Hordeum vulgare

Functional Descriptions:

• Differential expression of two β-amylase genes (Bmy1 and Bmy2) in developing and mature barley grain.
• Two barley (Hordeum vulgare L.) β-amylase genes (Bmy1 and Bmy2) were studied during the late maturation phase of grain development in four genotypes.
• Levels of Bmy1 mRNA were twenty thousand to over one hundred thousand times more than Bmy2 mRNA levels in genotypes Legacy, Harrington, and Ashqelon at all developmental stages and PI 296897 at 19 and 21 DAA. PI 296897 had five thousand times more Bmy1 mRNA than Bmy2 mRNA at 17 DAA.
• Bmy1 protein was far more prevalent than Bmy2 at all developmental stages in all genotypes. Thus, the vast majority of β-amylase activity in developing and mature grain can be attributed to endosperm-specific β-amylase.
