An adapted dendrogram of the Capsicum phylogeny is presented, showing taxonomic relationships between karyotypes of the Andean clade species, C. baccatum var. pendulum, C. flexuosum, and the sister group Lycianthes. To date, the Andean clade includes nine species: C. dimorphum, C. geminifolium, C. hookerianum, C. lanceolatum, C. longifolium, C. lycianthoides, C. piuranum, C. regale and C. rhomboideum, all displaying 2n = 26. This group is characterized by conspicuous cytogenetic characters that are very useful in the identification of their species and allow them to be distinguished from the other group of species with x = 13 from the Atlantic forest, and definitely from the clades with x = 12. The species of the Andean clade possess relatively short genomes, with one NOR per haploid complement. The distribution of the heterochromatin is mainly subterminal. A single locus of the 35S and 5S rDNA was found per haploid complement. The discovery of three pairs of 5S rDNA sites in C. regale was surprising. The chromosomal features of these highland clade species could be considered adaptive characters to their geographical distribution.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"6 1","pages":"584 - 593"},"PeriodicalIF":0.0,"publicationDate":"2023-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91496361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seed traits characterised before germination were tested. The seeds were incubated at temperatures of 10 to 30 °C and low osmotic potentials were induced using sodium chloride (NaCl) or polyethylene glycol (PEG 6000) solutions of 0 to −1.6 MPa. The capacity of seeds to recover and remain viable under stress conditions was quantified. Our results proved that the seed yields and sizes were uniform. The analysis of cardinal temperature by thermal time model exhibited an optimal germination temperature (T o) of about 19 °C, a base temperature (T b) of 0.6 °C and a ceiling temperature (T c) of 31 °C at 0 MPa. The base water potential Ψb (50) values ranged between −0.83 and −1.54 MPa and between −0.97 and −2.27 MPa for osmotic and salt stresses, at 30 °C and 20 °C, respectively. In conclusion, the species showed a lower seed recruitment related to a low drought tolerance (drought tolerance index = −0.5 MPa), To requirement and threshold sensitivity.

Despite in temperate forests the understory represents more than 80% of the plant diversity, it remains overlooked. The lack of knowledge is particularly evident for Italy, where coppice forests represent 42.3% of the forest cover and new demands for coppice revival are emerging. We reviewed the literature for Italy on the effect of coppice management on understory plants to summarize results, identify scientific gaps, propose research perspectives and provide management suggestions. The coppice management cycle is suitable for a great number of species with different functional strategies. The environmental changes occurring during tree regeneration after coppicing lead to the decrease of understory species richness and changes in both species and functional composition. Old-coppice forests feature impoverished understories, but they are characterized by less ruderal and alien species, and by shade-tolerant species with traits typical of mature forests. However, several issues remain, leaving uncertainty on the effective coppicing impact on understory, in particular the cross-scale effects of coppice management and the complex response of different diversity facets. We propose future studies to focus on these issues to avoid misleading management messages to users and policymakers.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"27 176 1","pages":"530 - 539"},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77837013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Determining the boundaries of the species in this genus has been faced with several problems, and their relationships are still poorly understood based on the recent phylogenetic studies. Therefore, the present study was designed to investigate the pollen micromorphology of 40 species of Iranian Onosma by scanning electron microscopy (SEM), to identify attributes perhaps important for a subgeneric classification. On the basis of pollen SEM images, three types of pollen shapes were observed, and the prolate pollen shape was predominant. In addition, three aperture types were observed. All species studied had microechinate, perforate, microechinate, verrucae, microechinate, perforate, and verrucate, microechinate exine sculpture. Based on cluster analysis and principal component analysis, the species studied were divided into two main groups showing different quantitative and qualitative traits. Therefore, the results of this study suggest that micro-morphological pollen traits can be used as valuable evidence in the taxonomy of the genus Onosma. However, we believe that palynology alone cannot successfully identify species in this genus and should use comprehensive evidence to identify species.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"38 1","pages":"437 - 454"},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83484105","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Considerable morphological work has been done on Lepidagathis, but some taxonomical doubts and contrasting interpretations still persist. Molecular analysis is the best tool to resolve the taxonomic doubts, but few nucleotide sequence data are available to date on Lepidagathis. Recently, some phylogenetic and morphological studies have proposed the inclusion of Teliostachya and Lophostachys in Lepidagathis. This work constitutes the first phylogenetic analysis of some Lepidagathis species based on chloroplast and nuclear regions. Both Bayesian and Maximum Likelihood phylogenetic analyses divide studied Lepidagathis species into two main clades, i.e. Clade A and B and place the Indian endemic Lepidagathis in Clade A with strong support. Phylogeny based on combined data resolve Lepidagathis, Barleria, and Crabbea lineages with stronger support than nrITS and cpDNA phylogenies. This phylogenetic study supports previous systematic revisions about the inclusion of Lophostachys and Acanthura species in Lepidagathis as well as the inclusion of Golaea and Acanthostelma into Crabbea species. In conclusion, this study constitutes a baseline molecular phylogeny for Lepidagathis and, in particular, contributes to the knowledge of the genetic diversity of Indian representatives of the genus.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"24 1","pages":"455 - 464"},"PeriodicalIF":0.0,"publicationDate":"2023-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77235300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sensitivity of P. syringae to the two types of EOs was investigated through three methods including disc diffusion, well diffusion, and vapor phase tests. Gas chromatography (GC) and gas chromatography attached to a mass spectrometer (GC-MS) were used to identify and quantify the essential oil compounds. The greatest growth inhibition zones for disc diffusion, well diffusion, and vapor tests were observed for the highest essential oil volume (50 µL) of Z. clinopodioides as 0.925 cm, 1.75 cm, and 1.45 cm, respectively. Concerning the EOs from C. copticum seeds, the diameters of growth inhibition zones were 0.775 cm, 1 cm, and 0 cm, respectively. Based on the obtained results, the highest antibacterial activity, with a growth inhibition zone of 1.75 cm, belonged to 50 µL EOs of Z. clinopodioides on Luria-Bertani (LB) agar medium. The minimum bactericidal concentration (MBC) and minimum inhibitory concentration (MIC) for the EOs of Z. clinopodioides were 8 µL mL−1 and 1 µL mL−1 in LB agar medium. The MBC and MIC values for EOs of C. copticum were 16 µL mL−1 and 1 µL mL−1, in LB agar medium, respectively. According to the chromatography results, 16 different compounds were identified in the EOs of C. copticum, of which thymol (54.6%) was the major constituent. Moreover, 27 different compounds were identified in the Z. clinopodioides EOs, of which pulegone (23%) and 1,8 cineole (20.3%) were the main essential oil constituents. The results demonstrated that the EOs of Z. clinopodioides plants had higher chemical diversity and displayed stronger antibacterial activities against P. syringe pv. syringae, compared to those of C. copticum.","PeriodicalId":20099,"journal":{"name":"Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology","volume":"12 1","pages":"487 - 492"},"PeriodicalIF":0.0,"publicationDate":"2023-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77129385","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To evaluate the capacity of heated apical and basal pistils to support and guide pollen tubes, we examined the performance of unheated pollen grains and their path along the pistil, as well as the anatomy of reproductive tissues. HT significantly induced a decrease in the number of adhered and germinated pollen grains and of pollen tubes in the style and the ovule micropyle. Microscopic observations revealed loss of stigmatic papillae turgidity and fertilization failures due to abnormal pollen tube paths. The latter finding was related to the high incidence of immature female gametophytes in apical pistils and unviable female gametophytes in basal pistils. Facultative apomixis is also described.
