DNA-based Data Storage Here to Stay | The Scientist Magazine®

DNA-based Data Storage Here to Stay | The Scientist Magazine® | Plant health | Scoop.it
The second example of storing digital data in DNA affirms its potential as a long-term storage medium.

Researchers have done it again—encoding 5.2 million bits of digital data in strings of DNA and demonstrating the feasibility of using DNA as a long-term, data-dense storage medium for massive amounts of information. In the new study released today (January 23) in Nature, researchers encoded one color photograph, 26 seconds of Martin Luther King Jr.’s “I Have a Dream” speech, and all 154 of Shakespeare’s known sonnets into DNA.

 

The researchers calculated that 1 gram of DNA could hold more than 2 million megabytes of information, though encoding information on this scale will involve reducing the synthesis error rate even further.

Knapco's insight:

The original article is not brand new, but it is worth mentioning: N. Goldman et al., “Towards practical, high-capacity, low-maintenance information storage in synthesized DNA,” Nature, doi: 10.1038/nature.11875, 2013.

This revolutionary experiment could develop into a new option for archival data storage, wherein DNA is not thought of as a biological molecule, but as a straightforward non-living data storage medium...

BMC Genomics | Full text | 'Bois noir' phytoplasma induces significant reprogramming of the leaf transcriptome in the field grown grapevine

Phytoplasmas are bacteria without cell walls from the class Mollicutes. They are obligate intracellular plant pathogens which cause diseases in hundreds of economically important plants including the grapevine (Vitis vinifera).
Knapco's insight:

This study revealed some fundamental aspects of grapevine interactions with the stolbur 'Bois noir' phytoplasma in particular and some plant interactions with phytoplasmas in general. In addition, the results of the study will likely have an impact on grape improvement by yielding marker genes that can be used in new diagnostic assays for phytoplasmas or by identifying candidate genes that contribute to the improved properties of grape.

"To create a sustainable, open research literature, governments need to find the finances to make it viable and recognize that adding value to diversifying research outputs has its own costs."

“The vision of an open research literature has both scientific merit and strong political support.”

Authors' final versions of papers should be deposited in the freely accessible database within a year of publication?

How Could Twitter Influence Science (And Why Scientists Are on Board) - Forbes | Plant health | Scoop.it

Via @haydn1701: The recent revelation that Twitter and social media can influence science is good news for people who want to understand the broader impacts of a more social world. But does the evidence stack up?....articles that many people tweeted about were 11 times more likely to be highly cited than those who few people tweeted about.

Update: New Pest & Disease Records (26 Dec 12)

Update: New Pest & Disease Records (26 Dec 12) | Plant health | Scoop.it

Claire Curry selected a few of the latest new geographic, host and species records for plant pests and diseases or their predators from CAB Abstracts. Some records of pests are:

  • First record of Trioza vitreoradiata (Maskell) (Hemiptera: Triozidae) in citrus.
  • Biological and serological diagnosis of Iris yellow spot virus in onion from northern India.
  • Fusarium chlamydosporum, causing wilt disease of guava (Psidium guajava L.) in India.
  • New distribution and lure records of Dacinae (Diptera: Tephritidae) from Queensland, Australia, and description of a new species of Dacus fabricius.
  • Chilli bud borer, Goethella asulcatta Girault in Andhra Pradesh.
  • First report of the invasive stink bug Bagrada hilaris (Burmeister) (Heteroptera: Pentatomidae) from New Mexico, with notes on its biology.

Q-bank Phytoplasmas database

Q-bank Phytoplasmas database | Plant health | Scoop.it

The Q-bank Phytoplasma database contains DNA sequences (Barcodes) of more than 100 strains that are of relevance to phytoplasma phytopathology.

 

Q-bank offers descriptions of well characterized regulated plants pests. It comprises ecological, morphological, physiological, and sequence data of items that are available in physical collections of plantpathogenic bacteria, fungi, insects, nematodes, phytoplasmas, viruses and viroids, and invasive plants.

 

The entries in Q-bank are continuously updated by a team of curators with taxonomic, phytosanitary and diagnostic expertise from world-wide national plant protection organizations and institutes with connections to relevant phytosanitary collections. Where relevant, information is linking to other databases such as European and Mediterranean Plant Protection Organization (EPPO).
