Gene Details:

• Gene ID: TraesCS2B02G073600
• Gene Symbol: RNHL-B1 Rht8
• Gene Name: Reduced height
• Genome: Chinese_Spring1.0
• Species: Triticum aestivum

Functional Descriptions:

• Designated ORF1 as RNHL-D1 and ORF2 as RNHL-D1.2. Two independent rnhl-d1 mutants showed significant reduction in plant height and spike length compared to the non-edited control. The RNHL-D1-overexpressing transgenic lines showed significantly increased plant height and SL.
• Suggesting a significant dosage effect of RNHL1 homoeologs in regulating plant height.
• Our phenotyping and genetic mapping analyses collectively suggested that these two newly identified EMS-induced mutants are allelic to Rht8, thus we renamed them Rht8-2 and Rht8-3,respectively. Rht8-2 and Rht8-3 reduced plant height and had no obvious negative impact on grain yield.
• A natural variation in Ribonuclease H-like gene underlies Rht8 to confer “Green Revolution” trait in wheat.
