By Gregory D. Reynolds, Chao Wang, Jianwei Pan, Sebastian Bednarek Introduction The plasma membrane (PM) serves as the interface between the cell and its environment. Accordingly, cells have the capacity to modulate their complement of PM-associated receptors, transporters, channels, lipids, and…

By Maureen R Hanson, Kevin M Hines ABSTRACT Stromules are narrow tubular structures, comprised of stroma surrounded by the envelope membrane, which emanate from all types of plastids found in vascular plants. The mechanism for formation of stromules is not understood, but investigating how they arise…

By Rashmi Sasidharan, Sjon Hartman, Zeguang Liu, Shanice Martopawiro, Nikita Sajeev, Hans van Veen, Elaine Yeung, Laurentius A.C.J. Voesenek Abstract Flooding is detrimental for nearly all higher plants including crops. The compound stress elicited by slow gas exchange and low light levels under…

By Junmarie Soto-Burgos, Xiao-Hong Zhuang, Liwen Jiang, and Diane C. Bassham Autophagy, literally defined as “self-eating”, functions as a degradation process by recycling cytoplasmic contents under stress conditions or during development. Upon activation of autophagy, a membrane structure known…

By Elias Kaiser, Alejandro Morales, Jeremy Harbinson The environment of the natural world in which plants live, have evolved, and within which photosynthesis operates, is one characterised by change. The time scales over which change occurs can range from seconds (or less) all the way to the geological…

Convincing molecular and biochemical evidence exists that members of the TRANSPORT INHIBITOR RESPONSE1/AUXIN SIGNALING F-BOX PROTEIN (TIR1/AFB) receptor family are auxin receptors that trigger auxin-induced gene expression and hypocotyl growth through enhanced expression of SMALL AUXIN UP RNA genes.…

Plant architecture is shaped by innate developmental programs as well as by adaptive responses to environmental cues. For example, the primary growth axis of shoots and roots is vertical, with lateral branches adopting some characteristic angle with respect to the main axis. If the main axis is tipped…

Due to its ease of use and noninvasive nature, variable chlorophyll fluorescence techniques have become increasingly popular for estimating photosynthetic parameters. Most measurements of variable chlorophyll fluorescence in complex plant tissues and surface-associated cell assemblages (e.g. biofilms)…
