Gene Details:

• Gene ID: BnaA07g27400D
• Gene Symbol: BnA07.IDA|BnaIDA-A07
• Gene Name: Inflorescence Deficient in Abscission7
• Genome:
• Species: Brassica napus

Functional Descriptions:

• BnC06.IDA and BnA07.IDA|BnaIDA-A07 share a highly conserved amino-acid sequence and exhibit 76.9% sequence similarity to AtIDA.
• Transcriptomic analysis revealed that BnC06.IDA and BnA07.IDA|BnaIDA-A07 were preferentially expressed in the floral abscission zone (AZ), and in other floral organs, including petals, sepals, and filaments.
• Our results suggest a role for BnC06.IDA and BnA07.IDA|BnaIDA-A07 in determining the fate of floral organ abscission.
• Demonstrate that BnA07.IDA|BnaIDA-A07 and BnC06.IDA are functionally redundant and are involved in the regulation of floral abscission in OSR.
• This suggests that BnA07.IDA|BnaIDA-A07 and BnaIDA-C06 may be involved in floral organ abscission in B. napus.
• We also generated plants overexpressing BnA07.IDA|BnaIDA-A07 (OE-BnA07.IDA|BnaIDA-A07) and found that the rate of floral organ detachment was greater than in the WT line.
• This result suggests that BnA07.IDA|BnaIDA-A07 and BnaIDA-C06 play a crucial role in silique dehiscence.
• Therefore, important agronomic traits were unaffected by the simultaneous knock out of BnA07.IDA|BnaIDA-A07 and BnaIDA-C06 genes in B. napus.
