SI is one of the most important traits in stone fruit breeding and particularly in apricot. Indeed, researchers focused their interests on identifying and selecting self-(in)compatible apricot parents for breeding programs and cultivars for the installation of new plantations. In this context, SI was studied in a set of 65 Tunisian apricot accessions focusing on both <i>S</i> and <i>M</i> loci targeting the genes, <i>S</i>-<i>RNase</i>, <i>SFB</i>, and <i>ParMDO</i>, with different primer combinations. The amplification of the first and the second intron of the <i>S</i>-<i>RNase</i> gene allowed the identification of nine different <i>S</i> alleles. The <i>S</i><sub>7</sub> allele which is reported to be present only in Southern Europe and North Africa regions was the most frequent occurring in 24 genotypes. Moreover, self-pollination tests and amplification of the <i>SFB</i> and <i>ParMDO</i> gene insertions (<i>S</i><sub>C</sub> and <i>m</i> haplotypes) producing pollen-part mutations (PPMs) that confer self-compatibility (SC) allowed us to correlate the presence of these two independent PPMs with SC for the first time within Tunisian apricot germplasm. Overall, nine accessions were found to be self-compatible carrying at least one self-compatible haplotype. The distribution of <i>S</i> alleles in the analyzed accessions supported the introduction of apricot to North Africa from the Irano-Caucasian region. Moreover, the detection of the self-compatible <i>ParMDO m</i> haplotype in Kairouan accessions similar to Spanish cultivars confirmed gene flow between Western European and North African apricots.

The performance of histone acetylation by HATs requires the involvement of other proteins to form multi-subunit complexes. The functions of three major HAT-containing complexes, namely SAGA, NuA4, and TFIID, have been extensively studied. Recently, the MEDIATOR complex was also found to be associated with HAT in <i>Arabidopsis</i>. However, these complexes have rarely been investigated in other plant species. In this study, we identify the subunits of four HAT-containing complexes in six different grass species by using <i>Arabidopsis</i> homologs as reference sequences. We then construct the phylogenetic trees to analyze their evolutionary relationships. The results indicate that all six grass species conserve all the subunits, despite gene duplication events occurring diversely in different species. Expression analysis shows that most of the genes encoding the subunits of the four HAT-containing complexes are constitutively expressed, with only low-level expression in pollen. Consistent with their cellular function, all four HATs are found to be localized in the nucleus in sorghum. Unlike their <i>Arabidopsis</i> counterparts, SbGCN5 specifically acetylates H3K4, H3K9, and H3K27, while SbMYST acetylates H4K5 and H4K12 in vitro. Additionally, we discover that SbTAF1 catalyzes acetylation of H3K9 and H4K5 for the first time.
