Does Potassium Modify the Response of Zinnia ( Jacq.) to Long-Term Salinity?

Salinity is one of the major abiotic stress factors hindering crop production, including ornamental flowering plants. The present study examined the response to salt stress of 'Lilliput' supplemented with basic (150 mg·dm) and enhanced (300 mg·dm) potassium doses. Stress was imposed by adding 0.

How chrysanthemum () 'Palisade White' deals with long-term salt stress.

Salinity is a serious problem in the cultivation of ornamental plants. Chrysanthemum () 'Palisade White' was evaluated in order to examine its responses to long-term salt stress. Plants were grown in substrate supplemented with NaCl doses (g dm of substrate) 0, 0.

Diadenosine polyphosphates (Ap3A and Ap4A) behave as alarmones triggering the synthesis of enzymes of the phenylpropanoid pathway in Arabidopsis thaliana.

It is known that cells under stress accumulate various dinucleoside polyphosphates, compounds suggested to function as alarmones. In plants, the phenylpropanoid pathways yield metabolites protecting these organisms against various types of stress. Observations reported in this communication link these two phenomena and provide an example of a metabolic "addressee" for an "alarm" signaled by diadenosine triphosphate (Ap3A) or diadenosine tetraphosphate (Ap4A).
