In order to initiate hairy root culture initiation cotyledons and hypocotyls of Calendula officinalis L. were infected with Agrobacterium rhizogenes strain ATCC 15834 or the same strain containing pCAMBIA 1381Z vector with β-glucuronidase reporter gene under control of promoter of NIK (Nematode Induced Kinase) gene. The efficiency of induction of hairy roots reached 33.8% for cotyledons and 66.6% for hypocotyls together for both transformation experiments. Finally, eight control and nine modified lines were established as a long-term culture. The hairy root cultures showed the ability to synthesize oleanolic acid mainly (97%) as glycosides; control lines contained it at the average 8.42 mg·g-1 dry weight in tissue and 0.23 mg·dm-3 in medium; modified lines: 4.59 mg·g-1 for the tissue, and 0.48 mg·dm-3 for the medium. Additionally lines showed high positive correlation between dry/fresh weight and oleanolic acid concentration in tissue. Using the Killiani mixture in acidic hydrolysis of oleanolic acid glycosides released free aglycones that were partially acetylated in such conditions.

The ornamental Tagetes minuta is a herbaceous plant of the Asteraceae family. T. minuta, a species native to southern South America, is used as a condiment, as a refreshing beverage, and for medicinal purposes. In 2011, disease symptoms of yellowing, root and foot rot, drying of leaves, and plant death were observed in an ornamental marigold (T. minuta) greenhouse in Fars province. The infected plants were collected and transferred to a laboratory. Samples were washed, cut into small pieces, surface disinfested with a 0.5% NaClO solution, and cultured on Potato Dextrose Agar (PDA) acidified to pH 4.5 with 0.5% lactic acid. Based on morphological characters, the causal agent was identified as Cylindrocarpon destructans. To confirm morphological identification, DNA was extracted from isolates using a genomic DNA purification Kit. The region of internal transcribed spacers 1, 2, and 5.8S genes of rDNA were amplified using the ITS4 and ITS1 universal primer set. Fragments of 600 bp were recovered from PCR, purified, sequenced, edited, and deposited in GenBank. The isolates had a 100% identity with all the compared C. destructans sequences. The pathogenicity tests were done with a suspension of 1 × 106 conidia per ml homogenised in sterile water. The symptoms on inoculated plants were similar to those previously observed and the fungus was reisolated from the inoculated plants. This is the first documented report of C. de-structans as a cause of root and foot rot disease on T. minuta in Iran.

Although chemical priming agents have been successfully used to improve seed germination, emergence and seedling quality in different plant species, still they are not yet useful for organic cultivation. Marigold is a multipurpose plant and rich source of lutein and gallic acid, to be explored as an organic priming agent. The purpose of this study was to identify an organic priming agent for organic growing and to develop appropriate methods by using two different species of marigold (Tagetes patula L. and T. erecta L.). Herbal tea obtained from the dried flower of marigold was used as a priming agent for eggplant (Solanum melongena L) cv. Pala seeds. Hydropriming and control seeds were compared with organic priming (T. patula and T. erecta) for germination percentage, mean germination time, germination rate, two different emergence tests, seedling height, seedling fresh and seedling dry weights. Data obtained from the application of organic priming (T. patula and T. erecta) showed a difference in both the germination (82 and 80%), and the emergence (73 and 76%) from Controls and Hydropriming. Seeds emerged in, which unprimed in 52 and 39% respectively, when primed with T. patula, emerged in 73 and 56% respectively. The mean germination time and the mean emergence time were shortened compared with Controls and Hydropriming. MET decreased in 1 cm and 2.5 cm depth sowing from 14.0 and 16.1 days than 10.3 and 11.9 days in Emergence-1 and 10.4 and 10.2 days in Emergence 2, respectively. Seedling quality characteristics were examined in the seedling height, the seedling fresh and dry weights of T. patula and T. erecta applications were also statistically significant. This is the first report which results showed that marigold species can be used as a potential organic priming agent.

In Poland, cultivars belonging to three species of Tagetes are grown: T. erecta, T. patula, T. tenuifolia. Presented studies were conducted in 2015 in two localities of the Lublin region. Those studies included cultivars of Tagetes spp.: T. erecta (cv. ‘Alaska’, ‘Hawaii’, ‘Mann Im Mond’), T. patula (cv. ‘Bolero’ and ‘Carmen’) and T. tenuifolia (cv. ‘Lemon Gem’ and ‘Lulu’). Six weeks after the sowing and in flowering stage of analyzed marigold cultivars, the plants healthiness was assessed. The mean values of the disease index ranged from 16.25 to 29.0. The main cause of root infection at the seedling stage proved to be the species of Fusarium and Rhizoctonia solani. Proportion of plants with disease symptoms in flowering stage ranged from 1.25 to 5.5%. Regardless of the place of cultivation, species: A. alternata, F. culmorum and F. equiseti were the most often isolated from diseased plants in the flowering stage. Studies on the susceptibility of analyzed cultivars of marigold to infection by Fusarium culmorum, F. equiseti and F. sporotrichioides were conducted in a growth chamber. Significantly, the lowest value of the disease index of cultivar ‘Bolero’ (T. patula) allows to accept that cultivar as the least susceptible to infestation by Fusarium spp. under conditions of controlled temperature and humidity.

The present study aimed to isolate and identify the chlorpyrifos resistant soil bacteria from contaminated soils in order to be used for bioremediation of polluted environments. Bacteria were isolated from two cultivated plant root rhizopheric soil of Cocks comb (Celosia cristata) and Marigold (Tagetes erecta).The pesticide was tested at 5 elevated doses,0.5%, 1%, 2%, 2.5% and control. Physiochemical properties of soils, PH, Electrical conductivity, Organic carbon, Organic matter, Nitrogen, phosphorus, potassium, Manganese and Iron were analyzed. Based on morphological and biochemical tests the isolates were identified as Bacillus subtilis, Pseudomonas putida, Pseudomonas aeruginosa. Thus, the organisms can be exploited for bioremediation of chlorpyrifos polluted soil, and their ability to degrade other organophosphates pesticide.
