Gene Details:

• Gene ID:
• Gene Symbol: PsAS1
• Gene Name: Asparagine synthetase 1
• Genome:
• Species: Pinus sylvestris

Functional Descriptions:

• Coordination of PsAS1 and PsASPG expression controls timing of re-allocated N utilization in hypocotyls of pine seedlings.
• The increase in transcript abundance observed at advanced stages of hypocotyl development was concomitant with a decrease of PsAS1 transcript abundance and a remarkable increase in the number of xylem elements and highly lignified cell walls.
• The increase in PsASPG transcript abundance observed at hypocotyl development stages H3 and H4, concomitant with the drastic decrease in PsAS1 transcript levels, suggests that high levels of ASPG are involved in the mobilization of the asparagine accumulated in the hypocotyl.
• These results, together with the precise localization of PsASPG transcripts in cells of the cambial region, suggest that the expression of PsAS1 and PsASPG is temporally coordinated, to control the re-allocation of N from seed storage proteins toward the hypocotyl to be later used during early development of secondary vascular system.
