This review describes a 50-year-long research study on the characteristics of Helianthus
tuberosus L. tuber dormancy, its natural release and programmed cell death (PCD), as well …

Programmed cell death (PCD) is a process that occurs throughout the life span of every
plant life, from initial germination of the seed to the senescence of the plant. It is a normal …

Numerous citations in the literature indicate that polyamines are intensively studied in
plants. Polyamines are implicated in many functions of the plant cell. Excellent recent …

We investigated free and conjugated polyamines after initiation of the cell cycle in Medicago
varia cell cultures. Phosphate starvation caused an arrest of cells, preferentially in the G1 …

Polyamines (PAs) have been considered as important molecules for survival. However,
evidence reinforces that PAs are also implicated, directly or indirectly, in pathways …

The results presented here attempt to correlate polyamines with dormancy, artificial break of
dormancy and natural release from dormancy. Aliphatic polyamines, now regarded as new …

The polyamines (PAs), spermidine (SPD) and spermine (SPN) and their diamine precursor,
putrescine (PUT) represent a set of evolutionarily highly conserved small molecular weight …

Research on polyamines (PAs) in plants laps a long way of about 50 years and many roles
have been discovered for these aliphatic cations. PAs regulate cell division, differentiation …

The earliest studies concerning polyamines (PAs) in plants were performed by using in vitro
cultured explants of Helianthus tuberosus dormant tuber. This parenchyma tissue was …

Crop production is significantly dwindled by a plenitude of pathogens that deprive the host
plants of nutrients, alter their physiological processes, and ultimately reduce yield. In order to …
