Understanding the dynamic nature of plant lipid anabolic and catabolic metabolism is key to sustainable oilseed engineering

New Phytologist, Volume 249, Issue 5, Page 2196-2214, March 2026.
Summary Plant‐derived oils are essential sources of reduced carbon and various fatty acid (FA) structures for food, biofuels, and the oleochemical industry. Despite extensive efforts, engineering mainstream oilseed crops to produce high levels of industrially valuable unusual FAs (UFAs) remains challenging.

Staining Germinating Pollen and Pollen Tubes

Stain Technology, 1958
Germinating pollen on stigmas and pollen tubes in styles of Antirrhinum, Brassica, Oenothera, Raphanus, Rosa, solatium and Tagetes spp. were prepared for examination as follows: The styles were fixed in ethyl alcohol-acetic acid 3:1 for 1 hr, and hydrolyzed at 60°C for 5 to 60 min (depending on the species) in 45% acetic acid.

Pollen Tube Development

2010
Pollen tubes grow rapidly in a strictly polarized manner as they transport male reproductive cells through female flower tissues to bring about fertilization. Vegetative pollen tube cells are an excellent model system to investigate processes underlying directional cell expansion.

Keeping pollen tubes on track

Nature Plants, 2020
A major question in plant reproduction is how pollen tubes perceive and decode female cues from the ovule for directional delivery of sperm cells. MILDEW RESISTANCE LOCUS-O proteins regulate pollen tube guidance by decoding ovular signals.

The pollen tube cytoskeleton

Electron Microscopy Reviews, 1991
In the last few years the role of pollen and the pollen tube in the fertilization process in higher plants has received considerable attention. By ultrastructural, biochemical and immunofluorescent investigations it has been shown that a cytoskeletal apparatus plays a central role in pollen tube growth.

The Pollen and Pollen Tube

1960
In 1694, Camerarius reported that anthers play the role of male sexual organs in plants (Maheshwari, 1950). Later, AMICI observed pollen tubes travelling through the stigma and style of Portulaca oleracea and in 1830 he concluded that pollen tubes elongate and ultimately come in contact with the ovule (Maheshwari, 1950). Since then the work of numerous

Pollen and Pollen Tube Proteomics

2007
Germinated pollen grains form pollen tubes that accomplish rapid polar- ized growth within female gametophytic tissues in order to deliver the sperm cell to the ovule. This process is essential for successful plant fertilization in vivo. Pollen tubes are considered to be an ideal model system to study tip growth. A more com- prehensive understanding of
