Genome-Wide Identification and Expression Analysis of the Kcs Gene Family in Lanzhou Lily Under Drought Stress Reveals Its Role in Abiotic Stress Response and Wax Accumulation
Research conducted by the Chinese Academy of Sciences has shed light on the crucial role of beta-ketoacyl-CoA synthase (KCS) in the synthesis of ultra-long chain fatty acids in Lanzhou lily under drought stress. The study, funded by the Gansu Postdoctoral Project Funding and the Gansu Provincial Science and Technology Program, identified 10 KCS genes in Lanzhou lily, which were divided into 6 subfamilies and evenly distributed on 10 different chromosomes. The research found that severe drought stress induced overexpression of the KCS gene, resulting in increased wax content and enhanced drought tolerance.
Key Takeaways:
- A total of 10 LbKCS genes were identified in Lanzhou lily under drought stress, divided into 6 subfamilies.
- The KCS protein of Lanzhou lily is mainly located in the plasma membrane and has 5 conserved motifs.
- All 10 LbKCS genes have two introns and one exon, except for LbKCS3 and LbKCS7.
- Severe drought stress induced overexpression of the KCS gene, resulting in increased wax content and enhanced drought tolerance.
- The research suggests that the KCS gene family plays a crucial role in the synthesis of ultra-long chain fatty acids and wax accumulation in Lanzhou lily under drought stress.
- The study provides valuable insights into the genetic basis of drought tolerance in Lanzhou lily and has important implications for crop improvement.
Statistics:
- 10 LbKCS genes were identified in Lanzhou lily under drought stress.
- The Ka/Ks values of KCS gene pairs of Lanzhou lily were less than one.
- The KCS protein of Lanzhou lily is mainly located in the plasma membrane.
- 5 conserved motifs were identified in the LbKCS genes.
- 2 introns and 1 exon were present in all 10 LbKCS genes, except for LbKCS3 and LbKCS7.
