“…The Plants 2020, 9, 375 6 of 16 highest differences in appearance and antioxidant status between the AMF-inoculated plants and the control were recorded in hyssop, and the lowest in tarragon ( Figure 3). Antioxidant defense plays a major role in protection against plant biotic and abiotic stresses [38,39]. Data presented in Table 3 reveal significantly lower levels of ascorbic acid, chlorophyll, carotenes, phenolics and total antioxidant activity of control plants compared to those inoculated with AMF, which was consistent with the aspect of samples subjected to high temperature and humidity ( Figure 2).…”

Utilization of arbuscular mycorrhizal fungi (AMF) for enhancing growth and development as well as production of essential oil in aromatic plants has been increasingly drawing research interest. In order to assess the AMF effects on different aromatic species, an open-field experiment was carried out using Artemisia dracunculus (tarragon), Lavandula angustifolia (lavender) and Hyssopus officinalis (hyssop). AMF stimulated the growth of tarragon and lavender plants, whereas hyssop showed a slight developmental slowing; nonetheless, a significant increase in essential oil content in the three species was seen. AMF application increased the biomass of A. dracunculus and H. officinalis by 20-35%. No differences in antioxidant activity and phenolics content were recorded at harvest between the control and AMF-inoculated plants, but the latter showed a significant increase in antioxidant status upon storage at high temperature and humidity compared to the untreated control. The enhancement of abiotic stress resistance during storage in plants inoculated with AMF was the highest in A. dracunculus, and the lowest in H. officinalis, while the untreated control plants showed a significant decrease in phenolics, ascorbic acid and chlorophyll content, as well as antioxidant activity, upon the abiotic stress. AMF inoculation differentially affected the mineral composition, increasing the accumulation of Se, I and Zn in A. dracunculus, and decreasing the levels of heavy metals and Co, Fe, Li, Mn in H. officinalis. Based on the outcome of the present research, AMF inoculation resulted in a significant enhancement of the overall performances of A. dracunculus, L. angustifolia and H. officinalis, and also in the improvement of plant antioxidant status upon storage in stress conditions.

Uniconazole (UNZ) can alleviate a variety of abiotic stresses such as low temperature. With application of UNZ on Coix lachryma‐jobi L. (coix) under low‐temperature stress, growth and physiological parameters were investigated in seedlings. Meanwhile, transcriptome profile in coix seedlings was characterized as well. The results showed an increase of 11.90%, 13.59%, and 10.98% in stem diameter, the aboveground and belowground biomass in 5 mg/L uniconazole application group (U3), compared with control check low‐temperature group (CKL). Some anti‐oxidase activities also show significant difference between CKL and U3 (p < .05). Transcriptome results showed that 3,901 and 1,040 genes had different expression level at control check (CK) and CKL, CKL and U3. A considerable number of different expressing genes (DEGs) related to the plant hormone signal transduction, photosynthesis, reactive oxygen species (ROS)‐related genes, and secondary metabolism in response to uniconazole application were identified in this study. The transcriptomic gene expression profiles present a valuable genomic tool to improve studying the molecular mechanisms underlying low‐temperature tolerance in coix. At the same time, it would provide a certain basis for the application of UNZ in the production of coix resistance under low temperature.

1112 Abstract 13 The seeds availability is the main constraint for the agricultural explosion in sub-Saharan 14 Africa countries. In the case of plantain, there is a lack of seedlings in quantity, but also in 15 quality. The advent of the PIF method was an excellent opportunity to improve the 16 availability of plantain seeds, although the quality is not fully guaranteed. Indeed, the PIF 17 plants produced have posed many problems during the acclimation period indicating a need 18 for solutions to improve their quality. Recent researches done with five treatments using 19 Tithonia diversifolia and clam shells have highlighted the improvement of the PIF seedlings 20 quality in terms of growth promotion (biofertilizer action) and protection against black 21 Sigatoka disease (biofungicide action). It seemed essential to determine the best model for 22 robust PIF seedlings. The aim of this study was to analyse the different models that have 23 enabled the production of improved PIF seedlings and to determine the best one. We have 24 modelized the response of PIF seedlings to the different treatment's protocols. It turns out that 25 the best treatment to apply is T5 (T. diversifolia liquid extract), followed by T4 (T. 26 diversifolia mulch). However, depending on the expected response in the PIF seedlings, all 27 these treatments have proven to be impactful. Tithonia diversifolia liquid extract model is the 28 best and in combination with clams, could be useful to boost the production at low cost and 29 without chemical inputs of large amount of improved vigorous (clean and less susceptible) 30 planting material, impacting thus the food security and poverty alleviation. 31 32
