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...
Root cortical senescence (RCS) is a poorly understood phenomenon with implications for adaptation to edaphic stress. Schneider et al. demonstrate that ethylene modulates RCS.
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...
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...
A study of silver maple cools embryonic axes to liquid nitrogen temperatures without prior dehydration or cryoprotection treatments and thaws them rapidly.
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...
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...
