Mitochondria and stress signalling

How does a plant sense stress and pass those signals around its body? Corentin Dourmap and colleagues have reviewed the role of...

Ethylene modulates root cortical senescence in barley

Root cortical senescence (RCS) is a poorly understood phenomenon with implications for adaptation to edaphic stress. Schneider et al. demonstrate that ethylene modulates RCS.

Dual role of reactive oxygen species in seed physiology (Review)

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.

Lysigenic PCD and schizogenously formed aerenchyma

This study reveals the optimal metabolic adaptation of E. densa stems to submerged habitats via lysigenic PCD and schizogenously formed aerenchyma

Opening a window on plant cell death

Let me introduce you to the wonderful world of the lace plant, Aponogeton madagascariensis. This exotic species native to streams in Madagascar has travelled far...

Mechanisms for ethylene-induced aerenchyma formation

Results suggest that ethylene is perceived in all maize root tissues and cortical-cell-specific PCD is controlled downstream of ethylene perception.

Programmed cell death in cryo-exposed embryonic axes

A study of silver maple cools embryonic axes to liquid nitrogen temperatures without prior dehydration or cryoprotection treatments and thaws them rapidly.

Role of PCD in the reproductive biology of kiwifruit

The results indicate that PCD in kiwifruit might be accelerated by pollination, suggesting its involvement during the progamic phase.

Pioneer root xylem development in Populus

Bagniewska-Zadworna et al. study the differentiation of tracheary elements (TEs) in pioneer roots of Populus trichocarpa grown in rhizotrons.

Ricinosomes and cell death in quinoa seeds

Early detection of Cys-EP in ricinosomes may predict the occurrence of programmed cell death during late seed development in quinoa.
