Reactive oxygen species (ROS) are considered to be detrimental to seed viability. However, recent studies have demonstrated that ROS have key roles in seed germination particularly in the release of seed dormancy and embryogenesis, as well as in protection from pathogens.
This study reveals the optimal metabolic adaptation of E. densa stems to submerged habitats via lysigenic PCD and schizogenously formed aerenchyma
Results suggest that ethylene is perceived in all maize root tissues and cortical-cell-specific PCD is controlled downstream of ethylene perception.
The results indicate that PCD in kiwifruit might be accelerated by pollination, suggesting its involvement during the progamic phase.
Bagniewska-Zadworna et al. study the differentiation of tracheary elements (TEs) in pioneer roots of Populus trichocarpa grown in rhizotrons.
Early detection of Cys-EP in ricinosomes may predict the occurrence of programmed cell death during late seed development in quinoa.
SEM and histological observations of the cellular events behind anther formation and programmed cell death in anthers of both male and female flowers.
