Gene Details:

• Gene ID:
• Gene Symbol: PsPK2
• Gene Name: Pisum sativum serine/threonine protein kinase2
• Genome:
• Species: Pisum sativum

Functional Descriptions:

• PsPK2 (the gene for a pea homolog of Arabidopsis PID , a regulator of PIN1 targeting), PsPIN1 (the major gene for a putative auxin efflux carrier) and LE (a gibberellin biosynthesis gene, GA3ox ), and also examined mutual hormonal regulation of these genes, in pea shoot tips, including a number of mutants.
• PsPK2 and PsPIN1 are positively regulated by gibberellin and auxin, and were induced to higher levels by simultaneous application of auxin and gibberellin.
• Auxin induction of Uni, PsPK2 and PsPIN1 did not require de novo protein synthesis. LE was positively regulated by auxin and cytokinin. In conclusion, these results support the hypothesis that auxin and gibberellin positively regulate Uni , which controls pea compound leaf development.
• Also, Uni, PsPIN1, PsPK2 and LE are expressed differentially in the leaf mutants, suggesting that mutual regulation by auxin and gibberellin promotes compound leaf development.
