The hybrid offspring of crosses between two different cultivars of a crop plant often tend to produce higher yields.

Most often the fungus shows up on grasses and other monocots plants often distinguished by flower parts in threes and parallel leaf venation such as pineapples, bananas and sugarcane,

Being able to judge which flowers will provide the most nectar, and which have already been plundered by other pollinators,
when they land on flowers, this charge helps pollen to stick to their hairs. Daniel Robert, a biologist at the University of Bristol, UK, knew that such electrical interactions would temporarily change the electrical status of the flowers
but he did not know whether bumblebees were picking up on this. Keen to find out, he and a team of colleagues measured the net charges of individuals of Bombus terrestris, a common species of bumblebee,
Next, the team placed the insects into an arena with petunias (Petunia integrifolia) and measured the flowers'electrical potentials.
Sure enough, when the bees landed, the flowers became a little more positively charged. Finally, the team released bumblebees into an arena with artificial flowers, half of which were carried positively charged
and a sucrose reward, and the other half of which were grounded and carried a bitter solution.
Over time, the bees increasingly visited the rewarding charged flowers. But when the researchers turned off the electrical charge on the flowers
and re-released the trained bees, the insects visited rewarding flowers only about half of the time,
as they would have by random chance. That suggested that the bees were detecting the electric fields

The sequence of Amborella trichopoda hints at the genetic adaptations that helped flowers to emerge
Amborella s gives a glimpse at changes that helped flowering plants, or angiosperms, to diversify from a common ancestor with gymnosperms another major plant lineage,
which includes conifer trees such as spruces. Comparisons of the genomes of Amborella and those of other plants suggest that an early ancestor of flowering plants gained a duplicate copy of its genome
a feature known as polyploidy. Many angiosperms are known to be polyploid potatoes, for instance, have between two and six copies of each chromosome.
But the duplication in Amborella predates all the other polyploids, says depamphilis, who led a team in 2011 that inferred this ancient duplication from more limited genetic data4.

The origin of flowers the defining features of angiosperms might be explained by a collection of genes that appeared
when angiosperms split from gymnosperms, analysis of the Amborella genome reveals. About one-quarter of the genes involved in flowering lack obvious counterparts in the genomes of gymnosperms,
whereas the other three-quarters existed in the common ancestor of both plant lineages. His team s analysis also provides insight into the evolution of complex seeds, floral scents and other features of flowering plants.
Keith Adams, a plant molecular geneticist at the University of British columbia in Vancouver, Canada, thinks the idea that a genome duplication helped flowering plants to diversify is"an intriguing hypothesis

#The origin of flowers: DNA of storied plant provides insight into the evolution of flowering plantsthe newly sequenced genome of the Amborella plant addresses Darwin's abominable mystery--the question of why flowers suddenly proliferated On earth millions of years ago.
The genome sequence sheds new light on a major event in the history of life On earth: the origin of flowering plants including all major food crop species. On 20 december 2013 a paper by the Amborella Genome Sequencing Project that includes a full description of the analyses performed by the project as well as implications for flowering plant research will be published in the journal Science.
The paper is among three on different research areas related to the Amborella genome that will be published in the same issue of the journal.
Amborella (Amborella trichopoda) is unique as the sole survivor of an ancient evolutionary lineage that traces back to the last common ancestor of all flowering plants.
and the University of California-Riverside--is uncovering evidence for the evolutionary processes that paved the way for the amazing diversity of the more than 300000 flowering plant species we enjoy today.
This unique heritage gives Amborella a special role in the study of flowering plants. In the same way that the genome sequence of the platypus--a survivor of an ancient lineage--can help us study the evolution of all mammals the genome sequence of Amborella can help us learn about the evolution of all flowers said Victor Albert of the University
at Buffalo. Scientists who sequenced the Amborella genome say that it provides conclusive evidence that the ancestor of all flowering plants including Amborella evolved following a genome doubling event that occurred about 200 million years ago.
Some duplicated genes were lost over time but others took on new functions including contributions to the development of floral organs.
therefore offer an explanation to Darwin's abominable mystery--the apparently abrupt proliferation of new species of flowering plants in fossil records dating to the Cretaceous period said Claude depamphilis of Penn State university.
Comparative analyses of the Amborella genome are already providing scientists with a new perspective on the genetic origins of important traits in all flowering plants--including all major food crop species. Because of Amborella's pivotal phylogenetic position
it is an evolutionary reference genome that allows us to better understand genome changes in those flowering plants that evolved later including genome evolution of our many crop plants--hence it will be essential for crop improvement stressed Doug Soltis of the University of Florida.
As another example of the value of the Amborella genome Joshua Der at Penn State noted We estimate that at least 14000 protein-coding genes existed in the last common ancestor of all flowering plants.
Many of these genes are unique to flowering plants and many are known to be important for producing the flower as well as other structures and other processes specific to flowering plants.
This work provides the first global insight as to how flowering plants are genetically different from all other plants On earth Brad Barbazuk of the University of Florida said
and it provides new clues as to how seed plants are genetically different from non-seed plants. Jim Leebens-Mack from UGA noted that The Amborella genome sequence facilitated reconstruction of the ancestral gene order in the'core eudicots'a huge group that comprises about 75 percent of all angiosperms.
This group includes tomato apple and legumes as well as timber trees such as oak and poplar. As an evolutionary outsider to this diverse group the Amborella genome allowed the researchers to estimate the linear order of genes in an ancestral eudicot genome
and to infer lineage-specific changes that occurred over 120 million years of evolution in the core eudicot.
since it split from the rest of the flowering plant tree of life. For example DNA sequences that can change locations
In addition to its utility in retrospective studies of the evolution of flowering plants the Amborella genome sequence offers insights into the history and conservation of Amborella populations.
There are only 18 known populations of this very special angiosperm in mountainous regions New caledonia. Resequencing of individual Amborella plants across the species'range reveals geographic structure with conservation implications plus evidence of a recent major genetic bottleneck noted Pam Soltis of the University of Florida.
