“…The possibility of formation of male, female, and hermaphroditic generative organs on one tree and the change of their ratio during tree development was shown for hybrids of white poplar ( Populus alba L.) and aspen ( Populus tremula L.) – gray poplar ( Populus × canescens (Aiton) Sm.) ( Sabatti et al., 2020 ). This is due to the fact that P. alba has a ZW system of sex determination and P. tremula has an XY system of sex determination ( Cronk and Muller, 2020 ; Muller et al., 2020 ).…”

Members of the genus Populus L. play an important role in the formation of forests in the northern hemisphere and are used in urban landscaping and timber production. Populus species of closely related sections show extensive hybridization. Therefore, the systematics of the genus is rather complicated, especially for poplars of hybrid origin. We aimed to assess the efficiency of application of the sex-determining region (SDR) in addition to the nuclear and chloroplast genome loci traditionally used in phylogenetic studies of poplars to investigate relationships in sections Aigeiros Duby and Tacamahaca Spach. Targeted deep sequencing of NTS 5S rDNA, ITS, DSH 2, DSH 5, DSH 8, DSH 12, DSH 29, 6, 15, 16, X18, trnG-psbK-psbI, rps2-rpoC2, rpoC2-rpoC1, as well as SDR and ARR17 gene was performed for 379 poplars. The SDR and ARR17 gene together with traditionally used multicopy and single-copy loci of nuclear and chloroplast DNA allowed us to obtain a clustering that is most consistent with poplar systematics based on morphological data and to shed light on several controversial hypotheses about the origin of the studied taxa (for example, the inexpediency of separating P. koreana, P. maximowiczii, and P. suaveolens into different species). We present a scheme of relationships between species and hybrids of sections Aigeiros and Tacamahaca based on molecular genetic, morphological, and geographical data. The geographical proximity of species and, therefore, the possibility of hybridization between them appear to be more important than the affiliation of species to the same section. We speculate that sections Aigeiros and Tacamahaca are distinguished primarily on an ecological principle (plain and mountain poplars) rather than on a genetic basis. Joint analysis of sequencing data for the SDR and chloroplast genome loci allowed us to determine the ancestors of P. × petrovskoe – P. laurifolia (female tree) × P. × canadensis (male tree), and P. × rasumovskoe – P. nigra (female tree) × P. suaveolens (male tree). Thus, the efficiency of using the SDR for the study of poplars of sections Aigeiros and Tacamahaca and the prospects of its use for the investigation of species of the genus Populus were shown.

“…This paucity of studies is probably due to the difficulty of conducting long‐term analyses (Husband & Schemske, 1996). Many studies relying on molecular markers to determine the paternity of individuals, however, have estimated levels of ID in wild tree populations (e.g., Aguiar et al, 2020; Duminil et al, 2016; Gonzaga et al, 2017; Griffin et al, 2019; Hardy et al, 2019; Lind et al, 2019; Pupin et al, 2019; Sabatti et al, 2020; Tambarussi, Boshier, et al, 2017; Tambarussi, Sebbenn, et al, 2017) and other perennial species (e.g., Duffy et al, 2020; Pinc et al, 2020; Wang, 2019).…”

The ornithophilous species Anagyris foetida L. is a Mediterranean shrub with highly fragmented populations and a mixed mating system. In a previous study, we analyzed the first 3 years of the life cycle of two progenies (selfed and outcrossed) grown from seed obtained by hand pollination and planted in an experimental garden in 2005. In that study, we found that inbreeding depression (ID) was manifested both reproductively and vegetatively throughout the life cycle, with male reproductive function being the most affected trait.

Within the genus Salix, there are approximately 350 species native primarily to the northern hemisphere and adapted to a wide range of habitats. This diversity can be exploited to mine novel alleles conferring variation important for production as a bioenergy crop, but also to identify evolutionarily important genes, such as those involved in sex determination. To leverage this diversity, we created a mapping population by crossing six Salix species (S. viminalis, S. suchowensis, S. integra, S. koriyanagi, S. udensis, and S. alberti) to common male and female S. purpurea parents. Each family was genotyped via genotyping-by-sequencing and assessed for kinship and population structure as well as the construction of 16 backcross linkage maps to be used as a genetic resource for breeding and selection. Analyses of population structure resolved both the parents and F1 progeny to their respective phylogenetic section and indicated that the S. alberti parent was misidentified and was most likely S. suchowensis. Sex determining regions were identified on Salix chromosome 15 in the female-informative maps for seven of the eight families indicating that these species share a common female heterogametic ZW sex system. The eighth family, S. integra × S. purpurea, was entirely female and had a truncated chromosome 15. Beyond sex determination, the Salix F1 hybrid common parent population (Salix F1 HCP) introduced here will be useful in characterizing genetic factors underlying complex traits, aid in marker-assisted selection, and support genome assemblies for this promising bioenergy crop.
