Phosphoinositides (PIs) are minor, but essential phospholipid constituents of eukaryotic
membranes, and are involved in the regulation of various physiological processes. Recent …

The moss Physcomitrella patens has emerged as an excellent model system owing to its
amenability to reverse genetics. The moss gametophyte has three filamentous tissues that …

Treatments that promote dormancy release are often correlated with changes in seed
hormone content and/or sensitivity. To understand the molecular mechanisms underlying …

The plant vascular system, and specifically the phloem, plays a pivotal role in allocation of
fixed carbon to developing sink organs. Although the processes involved in loading and …

The moss Physcomitrella patens receives increased scientific interest since its genome was
sequenced a decade ago. As a bryophyte, it represents the first group of plants that evolved …

Polarized cell expansion plays an important role in plant morphogenesis. Tip growth is a
dramatic form of this process, which is widely used as a model to study its regulation by …

Highlights•SEC14 proteins are key regulators of phosphoinositide (PIP) metabolism.•SEC14-
Nlj16 protein AtSFH1 controls root hair polarity.•Polybasic motifs in Nlj16 domains contribute …

Summary PtdIns‐4, 5‐bisphosphate is a lipid messenger of eukaryotic cells that plays a
critical role in processes such as cytoskeleton organization, intracellular vesicular trafficking …

The asymmetrical distribution of F-actin directed by cell polarity has been observed during
the migration of monospores from the red alga Porphyra yezoensis. The significance of …

Phosphatase and tensin homolog deleted on chromosome 10 (PTEN) is a lipid phosphatase
implicated in cellular proliferation and survival. In animal cells, loss of PTEN leads to …
