Expression

Organism Comment Expression
Lens culinaris the transcription of different isoforms of the large and the small subunits of the lentil enzyme are differentially regulated when the photoperiod shifts from long-day to short-day in stem and leaves. While transcript levels of large subunit LS1 and small subunit SS2 in leaf significantly decrease, overall transcript levels of small subunit SS1 increase in short-day regime additional information
