Microbios na Sarracenia alata

[cp_produtos]

Vivem mais microbios dentro da Sarracenia alata do que se pensava...

"Researchers from Louisiana State University used genomic fingerprinting technology to assess the bacterial diversity inside leaves of Sarracenia alata, commonly known as the pitcher plant. A pitcher plant is a carnivorous plant that lives in nitrogen poor soil augmenting the inadequate nitrogen by trapping and digesting insects. It has tubular shaped leaves that contain a liquid that is used for digestion. Over the past 35 years studying these plants using traditional culture-based methods, scientists have only identified 20 distinct bacteria in the pitcher.

"The microbial richness associated with the pitcher fluid from Sarracenia alata is high, with more than 1,000 phylogroups identified across at least seven phyla and over 50 families," say the researchers, who studied 10 plants in a Louisiana wildlife management area for 5 months during the spring and summer of 2009.

The researchers noted as well that approximately a third of all the bacteria were unidentifiable. They also observed that not only were the bacterial populations distinctly different from nearby soil samples, they started out different in each plant but over time they became more similar to one another.

"These findings indicate that the bacteria associated with pitcher plant leaves are far from random assemblages and represent an important step toward understanding this unique plant-microbe interaction," say the researchers.

Até existem animais que vivem as vidas todas dentro de pitchers. Quer das Sarras quer nas Nepenthes. Muitos ate levam nomes científicos consoante a espécie onde vivem.

Só uma curiosidade. Um deles (não me recordo o nome) vive na Darlingtonia. Eles quando a ânfora começa a secar mudam-se para outra folha que ainda esta por abrir. Agrupam-se lá imensos a espera que a folha abra e mal abre correm todos la para dentro!

vê-lá se descobres o nome e arranjas uma foto

Quanto aos bicharocos das Nepenthes, já há aí um tópico sobre essa "infauna".

Das Sarraceniaceae, nem por isso. Mas especificamente associados à Darlingtonia, fala-se dos Sarraceniopus darlingtoniae, e dos Metriocnemus edwardsi.

É algum destes Sérgio?

Ya esse mesmo Rafael. Não encontrei foi fotografias.

Descrição: "Another organism in Darlingtonia that truly depends upon the plant to live is a tiny creature called Sarraceniopus darlingtoniae. This has the unfortunate common name of "slime mite." Sarraceniopus adults live the whole summer and winter in pitchers, feeding upon bacteria. When the old pitchers decay in the spring, bands of Sarraceniopus climb out and gather near the newly forming pitchers' mouths. As soon as the pitchers open, the Sarraceniopus climb in and take up residence. Isn't that cute? And if that's not interesting enough for you, try this one--Sarraceniopus females are arrhenotokous, meaning that if they are unfertilized they give birth to offspring that are all males. That, my friend, is strange!" Sarracenia.com

Li por acaso este tópico, super interessante, então estes bichos são simbióticos? E existem mesmo essas 'mini larvas' nas darlings que se compra normalmente?
Se souberem responder a estas questões agradecia

Tomas quando quiseres beber o liquido das plantas pensa duas vezes...

como sabes que bebo o nectar das sarras??
