By switching 'bait,'IU biologists trick plants' bacterial defense into attacking virus
bait IU biologists plants bacterial defense attacking virus
2016/2/23
Scientists at Indiana University have modified a plant gene that normally fights bacterial infection to confer resistance to a virus.The method, described in a paper to be published Feb. 12 in the jou...
Ancient gene network helps plants adapt to their environments
Ancient gene network plants environments
2016/2/23
The only constant is change. In evolution, there are, however, some exceptions. While the enormous diversity of life suggests that organisms are constantly being refitted with new or modified parts, m...
Pity the poor plant. When faced with danger, animal species have their fight-or-flight response, but vegetation has no such option. Literally rooted in place, plants have taken defense to creative lev...
Selecting plants with increased total polyphenol oxidases in the genus Trifolium
expression analysis polyphenolic enzyme protein quality Trifolium medium Trifolium pratense
2015/12/29
One of the aims in red clover (Trifolium pratense) breeding is to increase the polyphenol oxidase (PPO) activity, which may effectively reduce protein breakdown in silage and when cattle are fed by fr...
Pineapple genome offers insight into photosynthesis in drought-tolerant plants
Pineapple genome photosynthesis drought-tolerant plants
2015/11/12
By sequencing its genome, scientists are homing in on the genes and genetic pathways that allow the juicy pineapple plant to thrive in water-limited environments. The new findings, reported in the jou...

Black bears in Yosemite National Park that don’t seek out human foods subsist primarily on plants and nuts, according to a study conducted by biologists at UC San Diego who also found that ants and ot...
Computational Mining and Survey of Simple Sequence Repeats (SSRs) in Expressed Sequence Tags (ESTs) of Dicotyledonous Plants
computational mining simple sequence repeats Expressed Sequence Tags
2015/5/26
DNA markers have revolutionized the field of genetics by increasing the pace of genetic analysis. Simple sequence repeats (SSRs) are repetitions of nucleotide motifs of 1 to 5 bases and are currently ...

Scientists stem cells in plants origin of beefsteak tomatoes
2015/6/2
A team of scientists at Cold Spring Harbor Laboratory (CSHL) has identified a set of genes that control stem cell production in tomato. Mutations in these genes explain the origin of mammoth beefsteak...
Vertebrate herbivore-induced changes in plants and soils: linkages to ecosystem functioning in a semi-arid steppe

Penn Scientists Identify Patterns of RNA Regulation in the Nuclei of Plants
Penn Scientists RNA Regulation Nuclei of Plants
2015/1/8
When the human genome was first sequenced, experts predicted they would find about 100,000 genes. The actual number has turned out to be closer to 20,000, just a few thousand more than fruit flies hav...
