Does the pathway of cell dismantling during programmed cell death in lace plant ( Aponogeton madagascariensis ) leave?
Results showed that a consistent sequence of events occurred during the remodelling of lace plant leaves, which provides an excellent system to study developmental PCD in vivo. These findings can be used to compare and contrast with other developmental PCD examples in plants.
A desensitization of soluble guanylate cyclase to activation with NO can be demonstrated under non-physiological conditions (disrupted cells) in homogenates from nitrate tolerant RA. However, in intact cells (in situ or in culture) soluble guanylate cyclase is not desensitized to EDRF, SIN-1 or SNP. Therefore reduced generation of NO from NTG because of impaired biotransformation of NTG must be regarded as the basis of nitrate tolerance.
