Training film: The correct handling with pocket bottles. This proposed mechanism for regulating sporogenesis in Arabidopsis shows some remarkable parallels to that in fungi. Similar to plants, fungi commonly have alternating haploid and diploid generations, and the formation of haploid spores constitutes an important step in their reproductive strategies. It has been shown that the disruption of Tup1 in yeast and its orthologs in some fungal pathogens, leads to defective spore production Most interestingly, in yeast there is a protein SSN6 that serves as an adaptor for the suppressor activity 11 , similar to the role of SPL in Arabidopsis.
The similarities between yeast and Arabidopsis in mechanisms governing a process that is as basic as reproduction raise the interesting question of whether this mechanism might be ancestral, possibly reflecting an original function of these co-repressors in promoting spore formation that has been retained in both the plant and fungal kingdoms.
