How does a plant sense stress and pass those signals around its body? Corentin Dourmap and colleagues have reviewed the role of mitochondria in the plant cell and how they interact with stress signalling. Image: Canva...

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...
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 to become the focus of the lab of Prof Arunika...

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.

Tapetum and middle layer control of male fertility in kiwifruit
Kiwifruit (Actinidia deliciosa) male-sterile anthers abort at the microspore-stage, but the role sporophytic tissues in controlling male-sterility is unknown. Falasca et al. show that the tapetum and middle-layer...
Programmed cell death drives male sterility in Opuntia
SEM and histological observations of the cellular events behind anther formation and programmed cell death in anthers of both male and female flowers.
Mastoparan-induced programmed cell death in Chlamydomonas
Under stress-promoting conditions unicellular algae can undergo programmed cell death (PCD), but the mechanisms are poorly understood. Yordanova et al. expose Chlamydomonas reinhardtii to the G-protein activator...
