Editing Salt marsh (section)

==== Bacteria ====
Examining [[16S ribosomal RNA|16S ribosomal DNA]] found in [[Yangtze]] River Estuary, the most common bacteria in the [[rhizosphere]] were [[Pseudomonadota|Proteobacteria]] such as [[Betaproteobacteria]], [[Gammaproteobacteria]], [[Deltaproteobacteria]], and [[Epsilonproteobacteria]].<ref>{{Cite journal |last1=Wang |first1=Meng |last2=Chen |first2=Jia-Kuan |last3=Li |first3=Bo |date=2007-10-01 |title=Characterization of Bacterial Community Structure and Diversity in Rhizosphere Soils of Three Plants in Rapidly Changing Salt Marshes Using 16S rDNA |url=https://www.sciencedirect.com/science/article/pii/S1002016007600654 |journal=Pedosphere |volume=17 |issue=5 |pages=545–556 |doi=10.1016/S1002-0160(07)60065-4 |bibcode=2007Pedos..17..545W |issn=1002-0160|url-access=subscription }}</ref> One such widespread species had a similar ribotype to the animal pathogen [[Serratia marcescens|S. marcescens]], and may be beneficial for plants as the bacteria can break down [[chitin]] into available carbon and nitrogen for plants to use.<ref>{{Cite journal |last1=Shobade |first1=Samuel O. |last2=Zabotina |first2=Olga A. |last3=Nilsen-Hamilton |first3=Marit |date=2024 |title=Plant root associated chitinases: structures and functions |journal=Frontiers in Plant Science |volume=15 |doi=10.3389/fpls.2024.1344142 |doi-access=free |pmid=38362446 |pmc=10867124 |issn=1664-462X}}</ref> Actinobacteria have also been found in plant rhizosphere in costal salt marshes and help plants grow through helping plants absorb more nutrients and secreting antimicrobial compounds. In Jiangsu, China, Actinobacteria from the suborders [[Pseudonocardineae]], [[Corynebacterineae]], [[Propionibacterineae]], [[Streptomycineae]], [[Micromonosporineae]], [[Streptosporangineae]] and [[Micrococcineae]] were cultured and isolated from rhizosphere soil.<ref>{{Cite journal |last1=Gong |first1=Yuan |last2=Bai |first2=Juan-Luan |last3=Yang |first3=Huan-Ting |last4=Zhang |first4=Wen-Di |last5=Xiong |first5=You-Wei |last6=Ding |first6=Peng |last7=Qin |first7=Sheng |date=2018-09-01 |title=Phylogenetic diversity and investigation of plant growth-promoting traits of actinobacteria in coastal salt marsh plant rhizospheres from Jiangsu, China |url=https://www.sciencedirect.com/science/article/pii/S072320201830167X |journal=Systematic and Applied Microbiology |volume=41 |issue=5 |pages=516–527 |doi=10.1016/j.syapm.2018.06.003 |pmid=29934111 |bibcode=2018SyApM..41..516G |issn=0723-2020|url-access=subscription }}</ref>
