Physiological characterization of a plastidic signal required for nitrate-induced appearance of nitrate and nitrite reductases.

abstract：MAIN CONCLUSION:Circular RNA (circRNA) discovery, expression patterns and experimental validation in developing tea leaves indicates its correlation with circRNA-parental genes and potential roles in ceRNA interaction network. Circular RNAs (circRNAs) have recently emerged as a novel class of abundant endogenous stable...

The course of senescence in leaves of corn seedlings, as measured by the loss of chlorophyll, is shown to be controlled by two correlative influences: a) In the isolated leaf, the base tends to enhance yellowing of the tip region. b) In the leaf attached to the intact plant, correlative aging is delayed by interact...
