Abstract
These proceedings contain the abstracts for the presentations given at the 7th biennial Seminars on Advances in Apomixis Research, held virtually on 2–3 and 9 December 2020. The first day hosted the kick-off meeting of the EU-funded Mechanisms of Apomictic Development (MAD) project, while the remaining days were dedicated to oral presentations and in-depth exchanges on the latest progress in the field of apomixis and plant reproductive biology research.
Highlights
A staggering increase in food production will be needed to feed a population of nearly 10 billion people in the near future
We have demonstrated that SPOROCYTELESS/NOZZLE (SPL/NZZ) a transcription factor required for Megaspore Mother Cell (MMC) specification is ectopically expressed in ago9 and drm1drm2 mutants suggesting that the multiple MMC-like phenotype might be due to its ectopic expression
Recurrent selection based on combining ability (RSCA) and recurrent phenotypic selection (RPS) were evaluated in a sexual synthetic tetraploid population (SSTP)
Summary
A staggering increase in food production will be needed to feed a population of nearly 10 billion people in the near future. Understanding the intricate networks controlling germline development, double fertilization, and seed formation is crucial for delivering innovative approaches to breeders and farmers [4,5]. In this context, the harnessing of apomixis, a natural phenomenon allowing the formation of maternal embryos within seeds [6,7], is among the most promising approaches [8]. Installing apomixis in major crops could accelerate breeding cycles and increase variety turn-over, expand genetic diversity by overcoming meiotic sterility resulting from wide crosses and inter- or high ploidy crosses. Despite decades of research, neither transfer attempts from wild apomictic relatives into maize [19] or pearl millet [20] nor the engineering of apomictic reproduction in a sexual crop [13] have yielded the expected results and the establishment of functional apomixis in major crops remains eagerly awaited
