Emily R Larson [email protected] School of Biological Science, University of Bristol, Bristol, UK ORCID: 0000-0002-5498-8152 Pollen tube growth through plant pistil tissues requires interactions between the male and female cells to regulate compatibility (McCormick, 1998), and hormonal and chemical signals that guide the pollen tube down through the style to the ovaries (reviewed in: Cameron […]
Emily R Larson, [email protected] Vesicle transport is one of those molecular processes that is easy to take for granted. From cell expansion and polarised growth to protein regulation and signalling, vesicle trafficking plays its unsung part. We tend to believe that we know a lot about this process and in truth, we do. Much work […]
Signaling within and between cells is fast and dynamic. Such signals can involve the transport of charged ions that change membrane polarity or intercellular gradients, protein de/phosphorylation, protein interactions, and phytohormones, among others. The change in protein distribution in response to these signals is hard to measure, particularly in real time, which limits our understanding […]
Polar localization of plasma membrane proteins is an important way cells regulate signaling pathways, transport across membranes, and growth. Polarization has obvious cellular effects, but localization of membrane components also contributes significantly to processes such as tip growth in root hairs and pollen tubes, phytohormone signaling, and directional micronutrient transport (Grunewald and Friml, 2010; Leitner […]
As the study of plant variation and characterization moves from measurements of largely organismal-level polymorphisms to those of cellular- and molecular-level traits, the need for morphological measuring tools that incorporate complex trait information is clear. While quantitative methodologies have improved, current methods rely on the researcher evaluating what morphological metrics to measure, and this results […]
