{"title":"Seed morphology of some Plantago (Plantaginaceae) species in Iran and its systematic and phylogenetic implications","authors":"S. Mohsenzadeh, M. Sheidai, F. Koohdar","doi":"10.55730/1300-008x.2745","DOIUrl":"https://doi.org/10.55730/1300-008x.2745","url":null,"abstract":": Plantago is a cosmopolitan genus with approximately 200 species and various infrageneric classifications have been reported. In this study, the seed morphologies of 19 species of Plantago from Iran were studied and documented in detail using scanning electron microscopy and light microscopy. The studied species were grouped by using statistical analyses such as a minimum spherical cluster method based on Euclidean distance, principal coordinate analysis, and multidimentional scaling. We have described four types based on the seed shape and states of the inner side of the studied seeds: convex-angular type, convex-elliptic type, flat-elliptic type, and concave-elliptic type. In this study, three types of seed coat patterns were recognized: reticulate, scalariform to reticulate, and papillate. Regardless of the limited range taxa considered, our data convincingly support a close relationship between subgenera Plantago and Coronopus , and between Albicans and Psyllium . Consequently, we would suggest that the species of subgenus Coronopus should be placed within subgenus Plantago as Pilger’s taxonomy, and the species of subgenus Albicans should be merged within subgenus Psyllium as Rønsted et al.’s taxonomy. The seed morphology revealed that subgenus Plantago and subgenus Albicans are paraphyletic. Moreover, the deformation of testa cells can be an indicator for finding different lineages at series to the subgenus level. The features of the arrangement of testa cells and anticlinal walls can be used at the species level, especially when the morphological diversity between species is low. We conclude that seed morphology provides useful and important information on phylogenetic relationships of Plantago species, and thus they have systematic significance.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43026464","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}

Solanum torvum is robust to Verticillium and some bacterial wilts and root-knot nematode. It was reported that interspecific hybrid plants originated out of the hybridization of these species were sterile. In our previous studies that have been carried out to overcome this interspecific hybridization barrier, only from Faselis F 1 that was used as the female parent, many interspecific hybrid seeds were obtained and 9.07% of the seeds grew into plants in vitro. The percentage of pollen viability and germination of tetraploid interspecific hybrid (amphidiploid) genotypes that have been produced by in vitro colchicine treatment, were 6.8 and 3.4 fold of its source diploid genotype, respectively. However, the increment was not high enough to overcome the interspecific hybridization barrier between S. torvum and S. melongena . In this study, the changes in pollen fertility of diploid interspecific hybrids and tetraploid plants, which have grafted on Pala or Faselis F 1 , were investigated. Pollen viability and germination percentage in diploid genotypes were not affected by grafting, although they increased significantly (51.54% and 119.73%, respectively) in tetraploid genotypes by grafting. It was determined that the fertile diploid rootstock used for the tetraploid genotypes that produced by chromosome doubling from cultured eggplants could increase the number of seeds per fruit. It was concluded that some fertile diploid varieties can be used as rootstocks in order to increase pollen viability, germination rate and seed yield of tetraploid genotypes with low pollen yield obtained from cultivated eggplant by chromosome doubling.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47181128","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}

This study aimed to effectively screen plants with strong tolerance to metal contamination by analyzing the levels of metals in Barbula rigidula (Hedw.) Mild. (BR), Barbula indica (Hook.) Spreng. (BI), and Barbula vinealis Brid. (BV) and in soils. The contents of metals in mosses obtained from the bauxite tailing area followed the following order: Al > Fe > Zn > Cu. Furthermore, the levels of these metals were highest in BR, followed by BI and BV. However, concentrations of Al (12,220–87,080 mg/kg), Fe (8520–62,690 mg/kg), Cu (98.5–185.4 mg/kg), and Zn (208.2–352.6 mg/kg) in soils greatly exceeded the background values. Bioconcentration factor (BCF) analysis showed that the uptake ability of mosses was 0.44–1.51, with BR having the highest uptake ability, especially for Al and Fe. The metal contamination factor (CF) in soils was 2.04–15.12, indicating that the soil was exposed to moderate to severe contamination. Correlation analyses found that Al and Fe levels in BR and soil were significantly positively correlated ( r = 0.898). PCA also confirmed that BR is a bioindicator and phytoremediation material of polluted soil in an abandoned karst bauxite tailing.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48241082","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}

This study aims to expand our current understanding by cultivating the diatom Cyclotella under controlled process conditions of a bubble column photobioreactor and analyzing CO 2 consumption dynamics in real time using results from an online CO 2 sensor connected to the reactor exhaust. Two sets of experiments were conducted: they served to contrast the influence of silicon and nitrate (Si&N colimitation) and Si limitation, and the light availability, respectively. CO 2 consumption was calculated based on the mass balance around the reactor inlet and outlet gas streams. Biomass samples and lipid extracts were analyzed for carbon (C) content to determine biomass-C and lipid-C concentrations. The outlet CO 2 concentrations varied significantly with cultivation time and process conditions. More than 15% to 65% of the CO 2 introduced left the reactor in the exhaust at any instance based on the set CO 2 transfer rates. The highest average daily capturing efficiency was 60%. Nutrient limitation regimes imposed generated unique CO 2 consumption profiles undiscernible by the biomass-C analysis, i.e. unlike Si limitation, N limitation had more immediate detrimental effects on C consumption. Final biomass-C concentration increased with increasing N and light availability, 275 mg/L vs. 336 mg/L, and 270 mg/L vs. 501 mg/L, respectively. Biomass-C based capturing efficiency approximations resulted in 20% to 40% underestimation. Under Si-limited conditions, the higher light intensity increased the final lipid-C to biomass-C ratio by two times (from 20% to 40%) and the final lipid-C concentration and peak productivity by four times (from 56 mg/L to 216 mg/L, from 7 to 30 mg/L-day, respectively). This study demonstrates online exhaust CO 2 concentration-based analysis’s unique capabilities for assessing carbon availability and capture, organic-C production, and its diversion to biomass and lipid production","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43976720","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}

This study aimed to investigate phenolic compounds; cytotoxic, antibacterial, and antioxidant activities; total phenolic (TPC) and flavonoid (TFC) contents of the methanol, ethanol, and water extracts of Padina pavonica (PP) and Zanardinia typus (ZT) . To the best of our knowledge, this is the first report in which ZT was evaluated in terms of phenolic content, antioxidant, antibacterial, and cytotoxic activities. The HPLC analysis allowed the identification of five phenolic compounds containing rutin (0.31 ± 0.04 – 3.00 ± 0.21 ppm) in all extracts and trans - p -coumaric acid (0.15 ± 0.02 – 3.95 ± 0.02 ppm) in MPP, EPP, MZT, EZT, WZT as the major compounds. TPC and TFC of the extracts were calculated as 11.78 ± 0.75 – 76.78 ± 0.54 µg GAEs/mg extract and 6.78 ± 0.17 – 29.50 ± 2.23 µg QEs/mg extract, respectively. The highest cytotoxicity was observed in EZT (CC 50 : 132.3 ± 22.4 µg/mL) against MCF-7 and MZT (CC 50 : 91.4 ± 20.9 µg/mL) against MIA PaCa-2. Among the studied extracts, EPP showed the best antibacterial activity against all test pathogens. Also, EPP indicated superior antibacterial activity against Plesiomonas shigelloides (MIC: 1.25 mg/mL) and Staphylococcus aureus (MIC: 1.25 mg/mL).

WRKY TFs are gaining considerable attention due to their significant roles in stress responses. However, their functions in sorghum ( Sorghum bicolor ) are lagging behind. In this study, a WRKY gene designated as SbWRKY45 was isolated and characterized from sorghum. SbWRKY45 , belonging to Group IIa, consists of one intron and two exons and encodes 430 amino acids. SbWRKY45 is located in chromosome 4. The cis -element prediction analysis showed that the promoter region of SbWRKY45 has several abiotic stress-associated elements. The qRT-PCR results showed that SbWRKY45 was significantly up-regulated in response to drought and cold under salt treatments, was notably changed, and was induced weakly under heat stress. SbWRKY45 exhibited a response to stress in different sorghum tissues, including leaves, stems, and roots. A tissue-specific expression pattern showed that SbWRKY45 was highly expressed in roots compared with leaves and stems, suggesting that SbWRKY45 may play an important role in roots. Overexpression of SbWRKY45 increased germination rates and promoted root growth in transgenic Arabidopsis under drought stress. Taken together, our findings indicate that SbWRKY45 may be involved in mediating the response to drought stress and play a vital role in the abiotic stress response of sorghum.","PeriodicalId":23369,"journal":{"name":"Turkish Journal of Botany","volume":" ","pages":""},"PeriodicalIF":1.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42633429","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}
