Abstract: Polyamines (PA) have a protective role in maintaining growth and development in Scots pine during abiotic stresses. In the present study, a controlled liquid Scots pine embryogenic cell culture was used for studying the responses of PA metabolism related to potassium deficiency. The transcription level regulation of PA metabolism led to the accumulation of putrescine (Put). Arginine decarboxylase (ADC) had an increased expression trend under potassium deficiency, whereas spermidine synthase (SPDS) expression d… Show more

“…Subsequent experiments also demonstrated that potassium deficiency could cause an increase in Put content. Other types of nutrient stress, such as magnesium deficiency, excess ammonia, and excess calcium, may lead to increased Put content and arginine decarboxylation (ADC) activity in plants [42][43]. According to another study, the polyamine content in plants abated under adversity stress.…”
