FIGURES 11–16. Nitella axillaris. 11. Whorl with a in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURES 11–16. Nitella axillaris. 11. Whorl with a small, axillary, sessile, compacted head, at a node of the thallus. 12. Whorl with a long, axillary, stipitate and compacted head. 13. 2-furcated fertile branchlet of a head. The black and red arrows indicate, respectively, the primary and the secondary nodes. 14. Dactyls 2-celled, abbreviated, forming a crown. Penultimate cell tapering gradually towards the base of end cell. End cell conical, acute or acuminate. 15. Oospore membrane with reticulate aspect under LM. 16. Oospore membrane with beaded imperfect reticulate aspect under SEM.
FIGURE 4 in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURE 4. Bayesian Phylogenetic tree based on ITS2 sequences. The numbers associated with the nodes indicate the bootstrap values (BS) for maximum likelihood and posterior probability (PP) for Bayesian analysis; nodes without values indicate BS <70% and PP <0.70; nodes with * indicate BS> 95% and PP>0.95 Sequences in bold are the new sequences generated in this study. Samples marked with "1" can be morphologically identified as N. acuminata (Wood & Imahori 1965); "2" with N. subglomerata (Wood & Imahori 1965).
FIGURES 29–34. Nitella microcarpa. 29. Upper whorls somewhat compacted. 30. Dactyls 2 in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURES 29–34. Nitella microcarpa. 29. Upper whorls somewhat compacted. 30. Dactyls 2-celled, abbreviated, forming a crown. Penultimate cell rounded at distal end. End cell conical and acuminate. 31. Fertile branchlet with gametangia at second (black arrow) and third (red arrow) nodes. 32. Oospore membrane with reticulate aspect under LM. 33. Overview of an oospore under SEM. 34. Oospore membrane with beaded imperfect reticulate aspect under SEM.
FIGURE 2 in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURE 2. Maximum likelihood Phylogenetic tree based on rbcL sequences. The numbers associated with the nodes indicate the bootstrap values (BS) for maximum likelihood and posterior probability (PP) for Bayesian analysis; nodes without values indicate BS <70% and PP <0.70; nodes with * indicate BS> 95% and PP>0.95 Sequences in bold are the new sequences generated in this study. Samples marked with "1" can be morphologically identified as N. acuminata (Wood & Imahori 1965); "2" with N. subglomerata (Wood & Imahori 1965).
FIGURE 1. A in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURE 1. A—Map of Brazil. The area highlighted in gray corresponds to the study region. B—Area of study with the sampling sites. The table indicates sampling sites for each species collected.
FIGURE 3 in Taxonomy and phylogeny of Nitella (Charophyceae, Characeae) from Brazil with emphasis on the midwest and southeast regions
FIGURE 3. Bayesian Phylogenetic tree based on ITS1 sequences. The numbers associated with the nodes indicate the bootstrap values (BS) for maximum likelihood and posterior probability (PP) for Bayesian analysis; nodes without values indicate BS <70% and PP <0.70; nodes with * indicate BS> 95% and PP>0.95. Sequences in bold are the new sequences generated in this study.
FIGURE 47 in Tolypella mongolica (Charophyceae, Characeae): A new dioecious charophyte species from the center of Eurasia and implications for charophyte taxonomy, including the validation of T. porteri and the new combination for T. jwalae
FIGURE 47. ML phylogenetic tree of Characeae (model TIM3+I+G) showing the position of the new species based on rbcL sequence data (46 sequences, 1354 aligned positions). Supports [(BP)> 50% and (PP)> 0.95: ML/BI] are provided above/below the branches. Branches received 100% BP and 1.00 PP support, and the newly obtained sequences of Tolypella mongolica sp. nov. are shown in bold. Sequences of the different species carrying one genotype are marked with grey. Tolypella sections are based on Wood & Imahori (1965). Prepared by V.Yu. Nikulin.
