“…These results are in close agreement with those obtained by Gajbhiye et al (2013), Abdou and Ibrahim (2015), Kumar et al (2018) and Beck et al (2019) (Khattab et al, 2017;Abbasi et al, 2020). Better vegetative growth should be directly reflected on various flowering aspects (Manzoor et al, 2019;Niazian and Nalousi, 2020).…”

A field experiment was carried out during two successive seasons of 2018/2019 and 2019/2020 at the Nursery of Ornamental plants, Faculty of Agriculture, Mania University. The aim of this study was to investigate impacts of compost at four levels (0, 5, 10 and 15 ton/fed) in combination with Microbein biofertilizer (M.B.) at 50 ml/plant and/or some antioxidant treatments (salicylic and ascorbic acids) on vegetative growth and flowering of Gladiolus grandiflorus var. Jester plants. Results showed that vegetative growth and flowering parameters of leaf length (cm), number of leaves/plant, leaves dry weight/plant (g), length of spike (cm), spike diameter (mm), spike fresh weight (g), number of florets/spike, lower floret diameter (cm) and lower floret fresh weight (g) were gradually increased with significant differences by increasing levels of compost. In addition, Microbein biofertilizer (M.B.) and/or some antioxidant (salicylic and ascorbic acids) treatments significantly increased all vegetative growth and flowering parameters in comparison with control treatment. Microbein biofertilizer plus salicylic acid and ascorbic acid were more effective in this concern. It was found also that the use of compost (15 ton/fed) in combination with Microbein biofertilizer plus salicylic acid plus ascorbic acid followed by 15 ton/fed with M.B. plus ascorbic acid then 10 ton/fed with M.B. plus salicylic acid plus ascorbic acid noticeably improved different vegetative growth characters and flowering parameters of gladiolus plants. As the most important characters for the quality of gladiolus, the largest length of spike (season one 65.76 cm and season two 65.76 cm), largest number of florets/spike (season one 11.65 and season two 11.98) and the highest lower floret diameter (season one 7.79 cm and season two 8.34 cm) were achieved with compost (15 ton/fed) in combination with Microbein biofertilizer plus salicylic acid plus ascorbic acid. From the results of this study, it could be concluded that adaptability of gladiolus corms of Jester variety (Gladiolus gradiflorus) to the Egyptian environmental conditions is confirmed.

“…As a consequence, both the quality and quantity of the secondary metabolite production receives a massive boost [ 6 ]. Such improvement could be obtained in proportionate terms across triploids, tetraploids and at other higher ploidy levels due to underlying multiple genetic dose effects [ 7 ]. However, such manipulative changes are also subject to genotype specificities.…”

Background Induced polyploidy serves as an efficient approach in extricating genetic potential of cells. During polyploidization, multiple sets of chromosomes are derived from the same organism resulting in the development of an autopolyploid. Alterations owing to artificially induced polyploidy level significantly influence internal homeostatic condition of resultant cells. Main text Induced autopolyploidy transpires as a result of an increase in the size of genome without any change in elementary genetic material. Such autopolyploidy, artificially induced via application of antimitotic agents, brings about a lot of beneficial changes in plants, coupled with very few detrimental effects. Induced autopolyploids exhibit superior adaptability, endurance to biotic and abiotic stresses, longer reproductive period and enzyme diversity coupled with enhanced rate of photosynthesis and gene action in comparison to their diploid counterparts. However, reduced rate of transpiration and growth, delay in flowering are some of the demerits of autopolyploids. Inspite of these slight unfavourable outcomes, induced autopolyploidization has been utilized in an array of instances wherein genetic improvement of plant species is concerned, since this technique usually boosts the biomass of concerned economic parts of a plant. In other way, it is also evident that multiplication of genome bestows enhanced production of secondary metabolites, which has contributed to a significant commercial value addition especially for plants with medicinal importance, in particular. Conclusion This review makes an attempt to explore the system and success of antimitotic agents vis-à-vis artificial autopolyploidization, interfered with the biosynthesis-cum-production of secondary metabolites having cutting-edge pharmaceutical importance.

“…The prerequisite to developing a genetically uniform F1 hybrid seed is the production of inbred lines through repeated self-pollination to obtain nearly homozygous parental lines [ 12 ]. This process is challenging in cannabis as it is a dioecious plant meaning the male and female reproductive systems occur on separate plants.…”

“…Feminized seeds are ideal for hemp cultivation to produce cannabinoids. While this approach provides an interesting solution to overcome the dioecy in cannabis plants, it is time-consuming and there is a belief that repeated artificial induction of male flowers results in an increased rate of hermaphroditism in the offspring [ 11 , 12 ]. Although the increased prevalence of hermaphroditism has yet to be evaluated, it is theoretically plausible through epigenetic mechanisms [ 9 ].…”

The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas-mediated genome editing system has recently been used for haploid production in plants. Haploid induction using the CRISPR/Cas system represents an attractive approach in cannabis, an economically important industrial, recreational, and medicinal plant. However, the CRISPR system requires the design of precise (on-target) single-guide RNA (sgRNA). Therefore, it is essential to predict off-target activity of the designed sgRNAs to avoid unexpected outcomes. The current study is aimed to assess the predictive ability of three machine learning (ML) algorithms (radial basis function (RBF), support vector machine (SVM), and random forest (RF)) alongside the ensemble-bagging (E-B) strategy by synergizing MIT and cutting frequency determination (CFD) scores to predict sgRNA off-target activity through in silico targeting a histone H3-like centromeric protein, HTR12, in cannabis. The RF algorithm exhibited the highest precision, recall, and F-measure compared to all the tested individual algorithms with values of 0.61, 0.64, and 0.62, respectively. We then used the RF algorithm as a meta-classifier for the E-B method, which led to an increased precision with an F-measure of 0.62 and 0.66, respectively. The E-B algorithm had the highest area under the precision recall curves (AUC-PRC; 0.74) and area under the receiver operating characteristic (ROC) curves (AUC-ROC; 0.71), displaying the success of using E-B as one of the common ensemble strategies. This study constitutes a foundational resource of utilizing ML models to predict gRNA off-target activities in cannabis.
