Recent studies show that Mortierella elongata can perform plant-growth promotion across different types of crops, including bahiagrass, corn, tomato, squash, and watermelon. Compared to the well-known species that have plant-growth-promotion abilities (e.g., mycorrhizal fungi, Trichoderma), growers, agents, and stakeholders are not familiar with "Mortierella" despite the important role these fungal taxa play in promoting the growth of their crops. This new 5-page publication of the UF/IFAS Department of Soil and Water Sciences provides a brief overview of Mortierella from biological, taxonomical, ecological, and functional perspectives to help readers learn the biology and potential modes of action of this fungus.

Mortierella Elongata

Abstract Calibrachoa (Calibrachoa x hybrida) is a highly valued solanaceous flowering ornamental plant, characterized by its drought-hardiness, abundant flowering, and diverse flower colors. Recently, the saprobic soil fungus Mortierella elongata was isolated as a root endophyte from eastern cottonwood (Populus deltoides) and identified as a potential biological amendment for bioenergy and food crops. Two greenhouse experiments were conducted by transplanting rooted cuttings of Calibrachoa cv. ‘Kabloom Deep Blue' into a potting media mixture amended with 1 or 2% volume mix ratio of millet seed colonized with one of four isolates of M. elongata. Plants were assessed weekly for flower production and 86 days post inoculation for leaf/stem, root, and total dry weight. M. elongata strain 624- significantly increased flower production compared to the non-inoculated millet seed controls at 6 and 7 wk post amendment in both experiments. Above and below ground vegetative dry weight for plants grown in potting media mixture amended with M. elongata isolates varied across isolates, fungal amendment concentrations, and experiments. Our results suggest that potting media mixture amended with M. elongata strain 624- can increase flower production of Calibrachoa during peak marketable periods. Index words: Calibrachoa, plant growth promotion, plant reproduction, biological amendment. Species used in this study: Calibrachoa (Calibrachoa x hybrida); Mortierella elongata Linnem.

Four Levels

The aims of this research is to find out the influence of the application of sago waste compost and PGPR on the increase in groundnut growth and yield and to obtain the dose of sago waste compost and PGPR concentration that able to increase the growth and yield of groundnut had been conducted in January to March 2016 in Maba Sangaji Village, Kota Maba Subdistrict, East Halmahera Regency. The research used factorial randomized complete block design consisting of two factors with three replication. Factor I was the dose of sago waste compost consisted of four levels: K0 = without sago waste compost (control), K1 = sago waste compost of 10 t ha-1, K2 = sago waste compost of 15 t ha-1, and K3 = sago waste compost of 20 t ha-1. Factor II was concentration of Plant Growth Promoting Rhizobacteria (PGPR) consisted of 4 levels: P0 = without PGPR (control), P1 = PGPR of 5 ml l-1, P2 = PGPR of 10 ml l-1, and P3 = PGPR of 15 ml l-1. The observation consisted of growth components of plant height, the number of leaves, leaf area, crop dry weight, and crop growth rate, and yield components of the number of pods, filled pods, empty pods, pod weight, grain weight, and weight of 100 grain. Research result shows that there was no interaction between the treatment of sago waste compost and PGPR. However, separately, treatments of sago waste compost and PGPR had the significant influence on the growth and yield of groundnut. The highest groundnut yield was obtained in the treatment of sago waste compost with the dose of 20 t ha-1. Grain weight obtained was 17.51 g or an increase of 52.15% compared to those of treatment without application of sago waste compost and yield of grain weight per hectare was 2.80 t ha-1. The inoculation of PGPR increased the growth and yield of groundnut. The application of PGPR with the concentration of 10 and 15 ml-1 produced better crop growth. The higher result was obtained in the treatment of PGPR with the concentration of 10 and 15 ml l-1with grain weight of 15.46 g and 16.81 g plant-1 or an increase of 31.15% and 42.6%, respectively, compared to control,whereas, grain weight per hectare was 2.47 t ha-1 and 2.69 t ha-1, respectively.

Our objective in this study was to determine to what degree macro and micro nutrients in water extracts, ethanol extracts and whole plant applications of Chinese chive (CC), soybean leaf (SL) and soybean stem (SS) promoted crop growth and if growth promotion was related to physiological elements such as photosynthetic efficiency. The studies we conducted in Suncheon, South Korea in 2017 also sought to confirm crop responses to abiotic and biotic stresses after treatment with CC, SL and SS extracts. We found that most nutrient levels in CC, SL and SS water extracts were higher than in ethanol extracts. Thus, growth promotion effectiveness may be related to plant extraction method, but not to the plants themselves or to physiological elements. Boiled water extracts of SL at 5% suppressed some fungi by 92% (Bortytis cinereal) and 57% (Colletotrichum coccodes), however several others were not effectively suppressed. Compared to the control, rice plant injuries induced by 50 mM NaCl were reduced by 20- 39%, 41-46%, and 40-46% in response to CC, SL and SS extract treatments at 0.5, 1, and 3%, respectively. Shoot fresh weight of rice subjected to 50 mM also increased by 38%, 15-52%, and 40- 59% in response to treatments of CC, SL or SS extracts at 0.5, 1, and 3%, respectively. Rice injuries under drought conditions were reduced 20-26% in response to treatment with CC, SL and SS extracts at 1, 3, and 5% when compared with control plants. Furthermore, the shoot fresh weight of rice under drought conditions was 3.6, 2.0, and 3.2 times greater when treated with CC, SL and SS extracts at 5%, respectively. Thus, the CC, SL and SS extracts used in this study mitigate salt and drought stresses and fungicidal effects, as well as promoting crop growth and could therefore contribute substantially to sustainable crop production.
