5 features to look for when selecting drone RGB sensors for phenotyping
Selecting a Drone to Meet Your phenotyping Needs: As drones have become better, less expensive, and easier to use, more researchers have been incorporating them into their trial assessment programs. The new generation of drones are bringing more capacity to assess new and previously inaccessible traits such as wheat head count, flower/fruit counting and classification, and phenological stage ...

New strategy of "two in one" rapid breeding
Xu Cao's research group from the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences published a paper titled “A two-in-one breeding strategy boosts rapid utilization of wild species and elite cultivars” online in Plant Biotechnology. This study reports a new "two-in-one" rapid breeding strategy, which combines the new de novo domestication breeding method and ...

Nitrogen Fixers
Here’s a bit of geeky plant science. On this image of the roots of white clover, you can plainly see bumps along the roots that are called nodules. Over millions of years, the plant has evolved a symbiotic relationship with certain species of soil-dwelling bacteria called Rhizobia. This group of bacteria has the ability to take nitrogen from the atmosphere and “fix” it by ...

Feasibility of seed production from nonflowering orchardgrass
Nonflowering or sparse flowering orchardgrass (Dactylis glomerata L.) would greatly simplify management of intensive rotational grazing systems. Our objective was to quantify seed production on nonflowering orchardgrass clones selected in cold-winter climates, but grown for seed in mild-winter climates. We evaluated 98 orchardgrass clones for seed production traits at four locations. Most plants ...

Ploidy determination and agronomic characterization of small burnet germplasm
Small burnet (Sanguisorba minor Scop.) is an evergreen forb readily utilized by livestock and wildlife that lacks persistence under heavy grazing. Our objective was to characterize all available National Plant Germplasm System (NPGS) small burnet germplasm for ploidy level and agronomic characteristics before initiating a breeding program. Ploidy level was determined by flow cytometry. Forage ...

Phenotypic and genotypic characterization of purple kernel streak in white food corn
Purple kernel streaking (PKS) in white food corn (Zea mays L.) is characterized by the accumulation of purple-pigmented streaks (anthocyanins) in an otherwise colorless pericarp. This paper is the first published report documenting PKS, the prevalence of the trait in commercial white food corn germplasm, and the genetics underlying it. Entries from the Early White Food Corn Performance Trials ...

Anthocyanin production by over-expression of grape transcription factor gene VlmybA2 in transgenic tobacco and Arabidopsis
An myb-related transcription factor gene of the anthocyanin biosynthetic pathway, VlmybA2, from the Kyoho grape (Vitis labruscana) was introduced into tobacco and Arabidopsis under the control of the cauliflower mosaic virus 35S promoter. The 35S:VlmybA2-induced anthocyanin production was prominent in transformed tobacco calli, and the regenerated tobacco plants were completely purple. Except for ...
