Although the impacts of habitat fragmentation on biodiversity were well studied, whether ecotones support biodiversity conservation or not is less understood, particularly in Sub-Saharan region. Hence, we compared woody species composition between ecotones and the adjoining vegetation types in Ethiopia. For this, firstly, four vegetation types, which are adjacent to each other at different sites, were selected from the vegetation map of Ethiopia. Secondly, a line transect (620 m in length) was laid out on ecotones at 50 m from the edges of the adjacent vegetation types on both sides. Moreover, transects that are equal in length to the ecotone transects were laid out on the adjoining vegetation types perpendicular to ecotone transects. Plots (size: 20 × 20 m each) were arranged on transects with 100 m interval. In total, from nine sites, 27 transect and 162 plots were used to collect data. The dissimilarity in woody species composition, differences in species richness and indicator species between ecotones and adjacent vegetation types were statistically analyzed. The results showed that woody species composition was dissimilar between ecotones and adjoining vegetation types. The species richness was significantly higher in ecotones when compared with the adjacent vegetation types. Moreover, the number of unique and endemic woody species was higher in ecotones than in adjoining vegetation types. The overall results suggest that ecotones promote plant diversity in Sub-Saharan Africa, as well as heterogeneity, and could be the focus of conservation in the face of continuing habitat fragmentation.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49389760","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By doing this early, we obtained results on the experimental translocation and thus better inform the measure proposed as part of the project. This project is likely to impact a large population of the plant species Helianthemum marifolium, which has a national protected status in France. We present here the pre-translocation phase, proposing different methodologies to better understand and prepare for a translocation. First, we studied the potential future distribution based on climate factors. Then, we sought to improve our knowledge of the local populations studied. To do this, we carried out pollinator surveys and a study of reproductive success. Finally, we presented the results of germination and cultivation tests, which enabled us to determine the mechanism for breaking dormancy and the most favourable substrate for growing, and we compared potential host sites regarding soil analyses. These different aspects allowed us to determine a protocol to be followed for a more significant translocation of this species. This case study illustrates requirements of the pre-translocation planning and can be used to inform future translocations of Helianthemum marifolium. The case study also presents methods other translocation practitioners can use to improve their protocols in the future.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2023-01-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42532580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, research on soil microflora and plant symbionts started only in the nineties and was mainly published during the last two decades. We aim to synthesize these studies, focusing particularly on arbuscular mycorrhizal fungi (AMF). Research on AMF consists firstly of a global and inventory approach aiming to produce a basic but essential lacking knowledge. These studies showed that AMF are abundant in ultramafic soils and concerned nearly all plant species of these ecosystems. Even Ni-hyperaccumulator plants and sedges, generally considered non-mycorrhizal, were found to be functionally colonized by AMF in New Caledonian ultramafic soils. The adaptation of AMF communities to the extreme conditions of these soils led to high levels of metal tolerance (particularly to Ni) and noticeable originality of the taxa. The influence of these symbionts on plant growth and adaptation was assessed in greenhouse and field conditions. An accurate selection of AMF isolates that improve plant growth, and plant metal tolerance was performed. It was demonstrated that combinations of AMF isolates with complementary functional traits showed highly synergistic effects on plant development. Finally, a partnership with a biotechnological company led to the production of an efficient commercial inoculant now used in the ecological restoration of mine-degraded areas. Today studies are focused mainly on the additive effects of AMF and mycorrhiza-helper bacteria.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49170014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is time-consuming to measure SD. Here, we provide a method for estimating SD based on the scaling relationship between SD and mean nearest neighbour distance (MNND) of sampled stomatal centres. 397 leaves from eight Magnoliaceae species were used for this study. For each leaf, three 1.2 mm × 0.9 mm lamina sections, positioned equidistantly between leaf left margin and midrib, were examined (in total 1189 sections). SD and MNND were calculated for each section. Regression protocols were used to test for a negative SD vs. MNND scaling relationship at the species and family levels. Additionally, 10 to 200 stomata from each section were randomly sampled to check for the prediction accuracy of SD using the SD vs MNND scaling relationship. There were significant differences in SD among the different lamina positions for 7 of 8 species. The inverse SD vs MNND scaling relationship was validated at the species and family levels. For the pooled data, the MNND values using 14, 25 and 50 stomata accounted for >80%, 85% and 90% of the variance in SD on a log-log scale, respectively. SD was characterized by high interspecific variability, and within-leaf variability, decreasing from the position near the midrib to that near the leaf margin. SD scaled inversely with MNND for the eight species. Thus, using the rapidly estimated trait MNND significantly simplifies and expedites the estimation of SD.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41343300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Lavender essential oils obtained from inflorescences harvested at bloom stage are mainly composed of monoterpenes and few sesquiterpenes. The characteristic lavender smell is due to linalool and linalyl acetate that represent more than half of the emitted volatile organic compound (VOC) quantity. These monoterpenoids are derived from plastidial pathway precursors. The regulation of this pathway in lavender is mainly managed by the successive expression of two DXS during flower development. In the light of 10 years of published data on lavender, it appears that biochemical pathways of main terpenes are mostly depicted. Several transcriptomic libraries are available and a genome at chromosome scale has been assembled and molecular markers developed. The diversity of lavender terpenes and their biosynthesis are reviewed with additional original data regarding the anatomical glandular structures and expression of genes involved in IPP biosynthesis.","PeriodicalId":54302,"journal":{"name":"Botany Letters","volume":null,"pages":null},"PeriodicalIF":1.5,"publicationDate":"2022-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45879282","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The scent samples were obtained by dynamic headspace, in situ in French Guiana, or from plants in the living aroid collection at the Botanical Garden of the University of Brasilia. Overall, we identified 43 volatile organic compounds (VOCs) belonging to the compound classes of monoterpenes, sesquiterpenes, irregular terpenes, benzenoids, aliphatics, jasmone derivatives, and nitrogen-containing compounds. Five of these floral VOCs are new reports for Philodendron. Interestingly, the floral blends in the investigated species were comprised of 3–22 VOCs; but when considering only major VOCs (≥5%), each fragrant blend could be summarized into one up to four constituents. Except for P. acutatum and P. billietiae, whose floral scents were largely dominated (≥93%) by 4-vinylanisole, fragrances of the investigated species were dominated (≥62%) each by a different VOC (i.e. dehydrojasmone, dihydro-β-ionone, (E)-4,8-dimethylnona-1,3,7-trien-5-yl acetate, methyl benzoate, 1,3,5-trimethoxybenzene, dihydrobovolide, or (Z)-jasmone).
