“…The present finding is in agreement with Kumar and Munirajappa (2013) who reported higher protein accumulation in mulberry leaves generated from 0.35% EMS. Stimulated increase in total protein concentrations at 1% EMS have also been reported by Ghani et al (2014) in gerbera (Gerbera jamesonii Hook. ).…”

“…Increase in the phenol content at higher mutagen dose showed a positive correlation with the antioxidant enzymes and could be aptly correlated with plant resistance mechanism for overcoming stress. Ghani et al (2014) found a significant increase in total phenol concentrations in in-vitro raised plants of Gerbera jamesonii with increasing dose of EMS treatment exhibiting maximum values at the highest dose of 1% EMS. Similarly, Rime et al (2019) reported an increase in the total phenol content in mango leaf in 0.8% of EMS treated mutants.…”

“…Significant alteration in EMS induced mutants have been reported to alter leaf area, chlorophyll pigments, total phenolic, proline and protein content etc. by various researchers (Ghani et al 2014, Deepthi and Ramesh 2016, Rime et al 2019. The mutated plants have been reported to regulate the anti-oxidant enzymes defence system to protect themselves against the harmful effects of reactive oxygen species (ROS).…”

The present study was carried out to enhance the genetic variability in Kinnow mandarin (Citrus nobilis Loureiro Physiological and biochemical responses of Kinnow mandarin (Citrus nobilis × Citrus deliciosa) to EMS induced mutagenesis Citrus deliciosa Tenora) using ethyl methanesulfonate (EMS) during 2016-17 and 2017-18. Plants created with different doses of EMS concentration, viz. 0.05%, 0.1%, 0.2% and 0.5% were examined for the various physiological and biochemical alterations in putative mutants aged six years and compared with the wild type (WT). A dose-dependent decrease in leaf area was recorded in the mutants with increasing doses of EMS concentration and as compared to WT, maximum reduction of 135.52 and 104.92% was witnessed in the mutants E-19 and E-17 developed from 0.5% EMS, whereas the leaves were more succulent in E-16. Chlorophyll a content was higher than chlorophyll b in the mutated population. As compared to WT, maximum decrease in chlorophyll a, total chlorophyll was noticed in the mutants E-19 generated from 0.5% EMS. Contrary to the physiological alterations, the total phenol, proline and total protein content in the mutants were upregulated by nearly two fold in the mutants developed beyond 0.1% EMS. Significant increase was also noticed in the antioxidant enzymes SOD, CAT, POX and GR activity in the mutants E-16 to E-20 induced from 0.5% EMS. The variation in traits of interest observed in the present study such as better leaf succulency and upregulated antioxidant enzyme activity in the mutant E-16 (0.5% EMS) suggests that the developed mutant could be utilised in Kinnow improvement for abiotic stress tolerance.

“…Although, both sexual and asexual propagation methods are available for multiplication, but these are insufficient to keep up with the huge demand (Murashige et al 1974). Micropropagation technology promises rapid and large scale multiplication and dependable propagation protocols have been established with different explants of gerbera (Altaf et al 2009;Ghani et al 2014). Like any other flowering plant, gerbera is also affected by a number of diseases, leading to poor flower quality and heavy monetary losses to the growers.…”

In this study, the effect of gamma irradiation in inducing resistance/tolerance towards powdery mildew disease was investigated in Gerbera jamesonii cv. 'Harley'. In vitro shoot cultures were established through capitulum explants on Murashige and Skoog medium supplemented with 22.2 lM 6-benzyladenine (BA) and 2.53 lM indole acetic acid (IAA), followed by gamma irradiation of regenerated shoots (3-5 cm). Activity of four antioxidant enzymes i.e. superoxide dismutase, ascorbate peroxidase, catalase and glutathione reductase increased significantly as compared to the control and reached to highest level at the most stringent doses of mutagen. Ninety randomly selected irradiated plants (6 months old) and 100 control plants were inoculated with fungal conidial suspension, to screen for tolerance/resistance against powdery mildew. The severity of the disease was recorded on 0-4 scale with '0' indicating highly resistant; '1' indicating resistant; '2' indicating medium resistance; '3' indicating susceptible and '4' indicating highly susceptible. Three plants (3.33%) irradiated with 5 Gy were found to be tolerant to powdery mildew as these plants showed slight and delayed development of fungal colonies on the leaves. The random amplified polymorphic DNA characterization showed that the irradiated plants had DNA patterns that were different from the control and mother plants.
