WebA fundamental mystery of plant cell biology is the occurrence of “stromules,” stroma-filled tubular extensions from plastids (such as chloroplasts) that are universally observed in plants but whose functions are, in effect, completely unknown. WebDec 18, 2024 · The importance of chloroplast activity during seed and embryo development is reflected in the large number of essential proteins localized to the chloroplast, many of them involved in PGE. The complete loss of SIG5 or RUG2/BSM results in embryo-lethal phenotypes ( Hsu et al., 2010; Babiychuk et al., 2011; seedgene.org).

WebJun 1, 2016 · Chloroplasts are defining organelles of photosynthetic eukaryotes. In addition to photosynthesis, plastids accommodate several essential pathways, such as fatty acid biosynthesis, making them indispensable, even in nonphotosynthetic tissues where they occur as nongreen plastid types ( Neuhaus and Emes, 2000 ). WebJan 1, 2006 · The Chloroplast Genome Database (ChloroplastDB) is an interactive, web-based database for fully sequenced plastid genomes, containing genomic, protein, DNA and RNA sequences, gene locations, RNA-editing sites, putative protein families and alignments ( http://chloroplast.cbio.psu.edu/ ). skipped due to when conditional
