#chloroplast — Public Fediverse posts

The unfiltered paper, with all the major deficits outlined by Kong's/New Phyt's #PeerReview experts still in it, is now online on bioRvix.

Worth et al. Whole #chloroplast #Genomes reveal a complex genetic legacy of #LostLineages, past radiations and #SecondaryContacts in the dominant temperate deciduous tree genus #Fagus

Being not limited, we moved a few more figures from the supplement to the main text 😎

A single cell's siesta: How non-moving #microbes manage to avoid bright light https://phys.org/news/2024-11-cell-siesta-celled-bright.html

Light-regulated #chloroplast morphodynamics in a single-celled dinoflagellate https://www.pnas.org/doi/10.1073/pnas.2411725121

"The structure that allows the chloroplast to make necessary changes was found to be a network of thin filaments. Together, these filaments form a material that can easily contract and expand in all directions."

`by assessing granule numbers during grain development in the phs1 mutant..we demonstrate that PHS1 is exclusively involved in B-type granule initiation. The total #starch content & # of starch granules per #chloroplast in leaves were not affected by loss of PHS1, suggesting that its role in granule initiation..is limited to the #endosperm..initiation of A- & B-type granules occurs via distinct..mechanisms..PHS1 plays an exclusive role in B-type granule initiation`

Researchers determine chloroplast size unlikely option for improving photosynthetic efficiency

A group of researchers have found, for the first time, that chloroplast size manipulations are unlikely to be an option for increasing crop photosynthetic efficiency.

Came across this astonishing parasitic #plant (the corpse flower: Rafflesia arnoldii) which produces these giant flowers (up to 1 m wide) when reading yesterday about plant hunters in a biography of Sir Joseph Banks.
Turns out the plant also has some fascinating #biology having lost its #chloroplast #genes from its #genome

Word of the day:

"Kleptoplasty, the process by which a host organism sequesters and retains algal chloroplasts, is relatively common in protists"

Doing some last minute double check analysis for our #NCM2022 poster. ANI syntenny for #Oxalis #chloroplast #genomes universally drop off in inverted repeat region A. Is this a common behavior for chloroplast genomes in general? But the identity match for IRBs seem to be pretty high.
