Title

Epidermal Cell Death in Rice Is Regulated by Ethylene, Gibberellin, and Abscisic Acid

Bianka Steffens; Margret Sauter PLANT PHYSIOLOGY 2005. doi:10.1104/pp.105.064469

Other claims from this paper (10)

Intervention effect Submergence induced death of epidermal cells covering adventitious root primordia.
Mechanism PCD induction depended on ethylene signaling.
Intervention effect Gibberellin promoted PCD induction.
Mechanism Ethylene and GA acted synergistically in converging signaling pathways.
Intervention effect Paclobutrazol increased PCD in response to ethylene and GA.
Mechanism Increased epidermal-cell sensitivity to GA was proposed to explain the paclobutrazol response.
Intervention effect ABA delayed ethylene-induced cell death.
Intervention effect ABA delayed GA-promoted cell death.
Mechanism Ethylene signaling was proposed as a target of ABA inhibition of PCD.
Mechanism Ethylene and GA accumulation with decreased ABA favors epidermal cell death before adventitious root growth.

IS PCD A RELIABLE INDICATOR OF BERRY QUALITY ATTRIBUTES IN WATER STRESSED VINEYARDS?

J.M. Pons; L. Serrano; C. Gonzales-Flor; et al. Acta Horticulturae 2013. doi:10.17660/actahortic.2013.978.8

Other claims from this paper (8)

Observation Predawn water potential ranged from -0.85±0.06 MPa to -0.50±0.07 MPa.
Association Berry quality attributes had no significant relationship with fIPAR.
Association Berry quality attributes were variably related to midday canopy-to-air temperature difference.
Method / resource SR had no significant correlation with berry quality attributes.
Association WI correlated significantly with midday canopy-to-air temperature difference at r = -0.82.
Method / resource WI estimated titratable acidity at r = 0.70.
Method / resource WI estimated maturation index at r = 0.70.
Recommendation WI may be more appropriate than SR or PCD for characterizing berry composition in water-deficit vineyards.

Observation Autophagosome-like vesicles were observed in healthy and dying cells.
Intervention effect Autophagy modulation noticeably increased vesicles and vacuolar aggregates.
Intervention effect Rapamycin enhancement of autophagy significantly decreased cell death rates against control.
Intervention effect Wortmannin inhibition of autophagosome formation had the opposite effect on cell death rates from rapamycin.
Intervention effect Concanamycin A blockade of cargo degradation had the opposite effect on cell death rates from rapamycin.
Intervention effect Promotion of autophagy in whole plants did not significantly affect the number of leaf perforations.

Observation The nrc2 mutant developed only mild disease.
Mechanism Nrc2 and Nrc3 act additively in Prf-/Pto-mediated immunity.
