Surface structure and properties of plant seed oil bodies
It is concluded that both oleosins and PL are required to stabilize the oil bodies and that oleOSins prevent oil bodies from coalescing by providing steric hindrance.
Ubiquitous and Endoplasmic Reticulum–Located Lysophosphatidyl Acyltransferase, LPAT2, Is Essential for Female but Not Male Gametophyte Development in Arabidopsis
Putative LPAT genes in Arabidopsis thaliana were examined and two related genes that encode the cytoplasmic LPAT were characterized, indicating that they could rescue the lpat2 female gametophytes to allow fertilization to occur but not to full embryo maturation.
Endoplasmic Reticulum, Oleosins, and Oils in Seeds and Tapetum Cells1
Diverse organisms contain neutral lipids in subcellular particles for food reserves and other purposes in seeds, flowers, pollen and fruit of higher plants, the vegetative and reproductive organs of primitive plants, algae, fungi, nematodes, mammalian glands and others.
A Novel Group of Oleosins Is Present Inside the Pollen ofArabidopsis *
A novel group of oleosins that is present inside the pollen ofArabidopsis thaliana is reported, and the success indicates that the organelles can be subjected to future biochemical and genetic studies.
Tapetosomes in Brassica Tapetum Accumulate Endoplasmic Reticulum–Derived Flavonoids and Alkanes for Delivery to the Pollen Surface[W]
Tapetosomes accumulate endoplasmic reticulum (ER)–derived flavonoids, alkanes, and oleosins for discharge to the pollen surface upon cell death, which protects the haploidic pollen from UV light damage and water loss and aids water uptake.
Plastid Lysophosphatidyl Acyltransferase Is Essential for Embryo Development in Arabidopsis1
The current findings of embryo death in the homozygous knockout mutant of the plastid LPAAT contrasts with earlier findings of a normal phenotype in the Homozygous mutant deficient of theplastid glycerol-3-phosphate acyltransferase; both mutations block the synthesis of plastsid phosphatidic acid.

Plant lipid droplets and their associated oleosin and other proteins have evolved and diversified in functions and cell species specificities and have been probed for commercial uses. Cytoplasmic
Cell Wall Reactive Proteins in the Coat and Wall of Maize Pollen
It is suggested that the pollen-coat β-glucanase and xylanase hydrolyze the stigma wall for pollen tube entry and that the flowers secrete proteins to loosen or become new wall constituents of the tube and to break the wall of the transmitting track for tube advance.
Proline Oxidase and Water Stress-induced Proline Accumulation in Spinach Leaves.
The in vitro activity of the enzyme under optimal assay conditions was high enough to prevent proline accumulation under water stress condition; presumably this activity was restrained in vivo.
