Plant Germline Development

New “Plant Germline Development – Methods in Molecular Biology”

The book “Plant Germline Development” includes cutting edge methods and protocols for the study of plant germline development. It also features a chapter on analyzing microspore and pollen quality using Impedance Flow Cytometry, written by Amphasys’ CTO Dr. Marco Di Berardino and Dr. Iris Heidmann. 

 

Analyzing pollen quality in an efficient and reliable manner is of great importance to the industries involved
in seed and fruit production, plant breeding, and plant research. Pollen quality parameters, viability and
germination capacity, are analyzed by various staining methods or by in vitro germination assays, respectively. These methods are time-consuming, species-dependent, and require a lab environment. Furthermore, the obtained viability data are often poorly related to in vivo pollen germination and seed set. In chapter 25, a quick and label-free method to analyze pollen is introduced, using microfluidic chips inserted into an impedance flow cytometer (IFC).

Amphasys at PAG in San Diego

Come join our workshop: “Why Pollen Matters – A Case Study of Improved Cross Pollination and Yield via Pollen Viability Analysis” and see a live demo of pollen viability analysis. January 15 at 12.50 – 3pm, Royal Palm Salon at PAG, San Diego.

Please RSVP to attend the workshop or to schedule a meeting during PAG 2018.

Amphasys at ISF World Seed Congress

Amphasys at ISF World Seed Congress (May 22 – 24, 2017)

Pollen is the seed of the seed companies, and seed is in the center of the International Seed Federation ISF Wold Seed Congress in Budapest. Therefore, the label-free, portable solution of Amphasys for the analysis of pollen viability is at the root of a successful business for the seed industry. Visit us at our booth 618.

Global warming – new publication about heat tolerance in pollen viability

High temperatures interfere with sexual reproduction and thus fruit and seed set. Heat tolerance was analyzed, among other things, by pollen viability and pollen number. Quantitative trait loci (QTLs) were identified for most of these traits, including a single, highly significant one for pollen viability, which accounted for 36% of phenotypic variation in the population and modified pollen viability under high temperature with around 20%.
