Other claims from this paper (11)

Observation Pear cells showed a decrease in protein and RNA synthesis to very low basal rates during the initial culture period.
Observation In batch culture, pear cell death occurred after 13 to 15 days.
Observation In batch culture, metabolic activity showed little or no change before cell death.
Intervention effect Renewal of the cell medium slightly delayed pear cell death.
Observation With medium renewal, a burst in RNA synthesis preceded cell death.
Observation With medium renewal, a notable increase in protein synthesis followed the RNA burst before cell death.
Observation In all instances, cell death was preceded by a burst in protein synthesis.
Intervention effect Cycloheximide inhibition of protein synthesis in pear cells is transient.
Intervention effect The effect of cycloheximide on cell longevity in pear cells is variable.
Intervention effect Actinomycin D (1.6 micromolar) did not significantly affect protein synthesis in pear cells.
Intervention effect Actinomycin D delayed RNA synthesis and cell death in pear cells.

Physiological Response of Three Alfalfa Cultivars to One Chilling Night¹

T. R. Peoples; D. W. Koch Crop Science 1978. doi:10.2135/cropsci1978.0011183x001800020015x

Other claims from this paper (10)

Intervention effect CO2 exchange rate of all three alfalfa cultivars was reduced following a 5 C night.
Intervention effect CER of Mesa-Sirsa was reduced 69.1% relative to the 18 C night after a 5 C night.
Intervention effect CER of Saranac was reduced 60.2% relative to the 18 C night after a 5 C night.
Intervention effect CER of Kane was reduced less (36.7% below the 18 C night) than in Mesa-Sirsa and Saranac after a 5 C night.
Intervention effect Transpiration rate was significantly reduced by 75.5% relative to 18 C following chilling in Mesa-Sirsa only.
Observation In Mesa-Sirsa, the reduction in transpiration was associated with a 50% increase in leaf diffusive resistance.
Observation Increased leaf diffusive resistance was not observed in Saranac and Kane following a chilling night.
Intervention effect Leaf carbohydrate concentration was greater in all three cultivars following a 5 C night.
Intervention effect Translocation of 14C photosynthate from leaf tissue was reduced in all three cultivars following a 5 C night.
Mechanism The authors suggest a feedback inhibition of CER in alfalfa following one 5 C chilling night.

Observation Auxin transport velocity was about 1.3 cm/h in active seedlings versus 0.3 cm/h in dormant seedlings.
Intervention effect At 1 C or under nitrogen, transport velocity fell to 0.2 cm/h.
Observation After 12 hours, more basal stem segments reached steady recoverable activity.
Observation Cold-treated shoots regained rapid transport seven days after favorable growing conditions began.
Observation Dormancy callose disappeared from phloem during shoot reactivation.
Observation Stem respiratory activity increased during shoot reactivation.
Observation Mitotic reactivation occurred in buds during shoot reactivation.

Observation At most five percent of applied tracer moved into the shoot.
Observation Substantial portions of applied tracer remained as indoleacetic acid.
