I tried to get as much elaioplast specific information as possible, but almost all the papers I found discussed elaioplasts as a subset of something else (e.g plastoglobuli -> plastoglobuli found in elaioplasts) and they share a lot of functions with the plastid family in general. Would it be better to include parts of this article as just a subset of the plastids page? Dtadelhelm (talk) 15:39, 11 February 2019 (UTC)

Hi I fixed a small problem with your content thus far (references go after punctuation per Wikipedia's style guide). I also noted that as you're moving forward with your work, it would be helpful for you to add links to other Wikipedia articles. This helps build the tree of knowledge on the site. Let me know if you have any questions! Elysia (Wiki Ed) (talk) 20:08, 11 February 2019 (UTC)

My suggestions to your Elaioplast page
Hi! I hope this is the preferred way to do this... Making my comments/suggestions here - take them or leave them - I had zero knowledge of elaioplasts before reading this so also probably very little credibility to critique here! I'll write my edits in bold.

Elaioplast project[edit source] Summary[edit source] Elaioplasts are one of the three possible forms of leucoplasts make a link here to leucoplasts, sometimes broadly referred to as such.[1] The main function of elaioplasts lies in the synthesis and storage of fatty acids, I would write: The main functions of elaioplasts are synthesis and storage... terpenes, and other lipids, and can be found in the embryonic leaves of oilseeds, citrus fruits, as well as the anthers of many flowering plants.[1][2][3][4] Within one of these organelles, oil droplets and plastoglobuli associated proteins can be found.[1] '''I know what oil droplets are, but not plastoglobuli. Either make a link to plastoglobuli or explain what those are here?'''

Description[edit source] As a type of leucoplast, elaioplasts are non-pigmented organelles capable of alternating between the different forms of plastids. '''This is a common character of a leucoplast? I think this is what you're trying to say with "As a type of leucoplast,"? I think you could say this more explicitly here. The elaioplast specifically is primarily responsible for the storage and metabolism of lipids,[5] among these, recent studies have shown that these organelles participate in the formation of terpenes and fatty acids.[2][3] Typically, they appear as small, rounded organelles filled by oil droplets.[1] Lipids found inside elaioplasts mirror those synthesized by prokaryotesInteresting, chiefly triacylglycerol and sterol esters, which cluster into the droplets visible by miscroscope.[1] As for their other components, elaioplasts also contain plastoglobuli associated proteins such as fibrillins, a protein family believed to be retained from their cyanobacterial ancestorsInteresting'''.[4] Alongside the tapetosomes, elaioplasts are frequently found in the tapetum of angiosperm anthers, where their products, oil from the plastid and protein from the tapetosome, are used to form the pollen coat of developing grains.[1] Following the maturation of pollen grains, these organelles are degraded and released into the anther loculus[1]. Found also in oilseeds, elaioplasts here provide lipids for the conversion to carbohydrates to serve as fuel in the embryo's germination.[4] Citrus specimens have been shown to have especially high amounts of elaioplasts in their fruit peels, where they have been showshown to be essential to the production of terpenes.[5] '''I do feel like you say "been shown" a lot.. Maybe find different ways of rephrasing?'''

Origin[edit source] Not necessary? would just be a repeat of whats described on the Plastids page. '''But I'm not on the plastids page, and as a typically lazy wikipedia user, will likely be too lazy to go there... Maybe rephrase/condense what's on there - at least the parts relevant to your elaioplasts? I'm not sure what you'd want to put in the origin sections, but if we're talking about evolutionary origin, could you move the bits about the cyanobacterial ancestors here and expand on that?'''

Development[edit source] Within the plant, elaioplasts, as well as all other plastids, arise from proplastids link to pro plastids here or explain what they are in the dividing portion of the stem (meristem). These proplastids have not yet differentiated and, as such, can develop into any variety of known plastids, determined by the tissues they are present in.[6] In vegetative cells, proplastids usually follow a unidirectional pathway of development with no reversals between one form and the next. Reproductive cells, however, may have plastids that inter-convert frequently.[7] In the anthers of flowering plants, elaioplasts represent the final stage of plastid development within the tapetum link here or explain tapetum, either emerging directly from proplastids or the conversion of other plastids, depending on the species and pollination strategy.[7] maybe an example or two of different pollination strategies and how they develop differently in each?

Inheritance[edit source] '''feels like origin to me? I guess I'm confused about the difference between origin and inheritance? Please ignore my comments if this is just a reflection of my ignorance of conventional ways of describing cellular entities...''' Like most plastids, elaioplasts reproduce through fission, a feature indicative of their bacterial ancestry, when the cell they are housed in divides[1]. This fission occurs just before cytokinesis, with the products then being transported to the daughter cells as a component of the cytoplasm.[1]

As a result of the ability to inter-convert between other members of the plastid family, elaioplasts share the same plastome (plastid genome) with all other plastids and are predominately inherited maternally in angiosperms.[5][7] As its name implies, maternal inheritance excludes the plastome of the father through one of two ways: during pollen development or in pollen tube formation[7]. During pollen development, paternal plastids are halted by microfilaments in the cytoskeleton just prior to microspore mitosis or degeneration just after.[7] Paternal plastome contribution can also be prevented during pollen tube formation, where the plastids are separated from spermssperm cells as they fuse with the egg.[7] — Preceding unsigned comment added by Annabecker234 (talk • contribs) 18:09, 13 February 2019 (UTC)

Summary Elaioplasts are one of the three possible forms of leucoplasts, sometimes broadly referred to as such.[1] The main function of elaioplasts lies in the synthesis and storage of fatty acids, terpenes, and other lipids, and they can be found in the embryonic leaves of oilseeds, citrus fruits, as well as the anthers of many flowering plants.[1][2][3][4] '''Within one of these organelles [what does this mean? which one?], oil droplets and plastoglobuli [make this a link to its wiki page]''' associated proteins can be found.[1]

Description As a type of leucoplast, elaioplasts are non-pigmented organelles capable of alternating between the different forms of plastids. The elaioplast specifically is primarily responsible for the storage and metabolism of lipids,[5] among these [among what??], recent studies have shown that these organelles participate in the formation of terpenes and fatty acids.[2][3] Typically, they appear as small, rounded organelles filled by oil droplets.[1] Lipids found inside elaioplasts mirror those synthesized by prokaryotes, chiefly triacylglycerols and sterol esters, which cluster into the droplets visible by microscope.[1] As for their other components, elaioplasts also contain plastoglobuli associated proteins such as fibrillins, a protein family believed to be retained from '''their [whose ancestors? who is the "their" referring to?] cyanobacterial ancestors.[4] Alongside the tapetosomes [this needs to link to its wiki page, and perhaps include a brief definition in parentheses here], elaioplasts are frequently found in the tapetum [again, link to its wiki page]''' of angiosperm anthers, where their products, oil from the plastid and protein from the tapetosome, are used to form the pollen coat of developing grains.[1] Following the maturation of pollen grains, these organelles are degraded and released into the anther loculus[1]. Found also in oilseeds, elaioplasts here [where?] provide '''lipids for the conversion to carbohydrates [do you mean that the lipids will be converted to carbohydrates? Then state that more directly]''' to serve as fuel in the embryo's germination.[4] Citrus specimens have been shown to have especially high amounts of elaioplasts in their fruit peels, where they have been show to be essential to the production of terpenes.[5]

Origin Not necessary? would just be a repeat of whats described on the Plastids page. '''I agree with Anna, say something brief here, and link to the plastids page. Or, you could combine this with the next section and call it "Origin and Development".'''

Development Within the plant, elaioplasts, as well as all other plastids, arise from proplastids in the dividing portion of the stem (meristem). These proplastids have not yet differentiated and, as such, can develop into any variety of known plastids, determined by the tissues they are present in.[6] In vegetative cells, proplastids usually follow a unidirectional pathway of development with no reversals between one form and the next. Reproductive cells, however, may have plastids that inter-convert frequently.[7] In the anthers of flowering plants, elaioplasts represent the final stage of plastid development within the tapetum, either emerging directly from proplastids or the conversion of other plastids, depending on the species and pollination strategy.[7]

Inheritance Like most plastids, elaioplasts reproduce through fission [it needs to be clearer here that it's the cell that's dividing, not the plastids themselves], a feature indicative of their bacterial ancestry, when the cell they are housed in divides[1]. This fission occurs just before cytokinesis, with the products then being transported to the daughter cells as a component of the cytoplasm.[1]

As a result of the ability to inter-convert between other members ["types" might be a more appropriate word] of the plastid family, elaioplasts share the same plastome (plastid genome) [link to appropriate wikipedia page] with all other plastids and are predominately inherited maternally in angiosperms.[5][7] As its name implies, maternal inheritance excludes the plastome of the father through one of two ways: during pollen development or in pollen tube formation[7]. During pollen development, paternal plastids are halted by microfilaments in the cytoskeleton just prior to microspore mitosis or degeneration just after.[7] Paternal plastome contribution can also be prevented during pollen tube formation, where the plastids are separated from sperm cells as they fuse with the egg.[7] — Preceding unsigned comment added by Emilysessa (talk • contribs) 13:58, 19 March 2019 (UTC)
