The mechanisms of PGPR in increasing plant growth include biofertilizers, biostimulants, phytohormones, producing siderophores, dissolving phosphates, and bioprotectant agents. Seed biopriming allows bacteria to enter/attach to the seed and is effective in promoting seed emergence and suppressing disease. The purpose of this study was to analyze PGPR indigenous from peat soil as seed biopriming for the initial growth of corn plants inoculated with Fusarium sp. in vivo. The study was conducted in the laboratory, using agar media for seeding sweet corn seeds to be organized into a single factor completely randomized design, consisting of 12 treatments and 2 controls, to be repeated 3 times. The results showed that the treatment significantly affected the root dry weight variable and did not differ significantly from the root roaming variable, plumula length, plumula wet weight, plumula dry weight, and root wet weight and Fusarium disease attack. The biopriming treatment using rhizobacteria Bacillus cereus gave effect to the highest root dry weight, significantly different from the treatment of Burkholderia cepacia + Fusarium sp. and Brevibacillus laterosporus + Fusarium sp. Seed biopriming treatment on Fusarium sp. disease resistance inoculated on corn seeds showed no significant effect. The use of biopriming contributes to the reduction of inputs of environmentally unfriendly synthetic products.

Plant diseases and pests reduce crop yields, accounting for global crop losses of 30% to 50%. In conventional agricultural production systems, these losses are typically controlled by applying chemical pesticides. However, public pressure is mounting to curtail agrochemical use. In this context, employing beneficial endophytic microorganisms is an increasingly attractive alternative to the use of conventional chemical pesticides in agriculture. A multitude of fungal endophytes are naturally present in plants, producing enzymes, small peptides, and secondary metabolites due to their bioactivity, which can protect hosts from pathogens, pests, and abiotic stresses. The use of beneficial endophytic microorganisms in agriculture is an increasingly attractive alternative to conventional pesticides. The aim of this study was to characterize fungal endophytes isolated from apparently healthy, feral wine grapes in eastern Canada that have grown without agrochemical inputs for decades. Host plants ranged from unknown seedlings to long-lost cultivars not widely propagated since the 1800s. HPLC-MS was used to identify unique endophyte-derived chemical compounds in the host plants, while dual-culture competition assays showed a range in endophytes’ ability to suppress the mycelial growth of Botrytis, which is typically controlled in viticulture with pesticides. Twelve of the most promising fungal endophytes isolated were identified using multilocus sequencing and morphology, while DNA barcoding was employed to identify some of their host vines. These fungal endophyte isolates, which consisted of both known and putative novel strains, belonged to seven genera in six families and five orders of Ascomycota. Exploring the fungal endophytes in these specimens may yield clues to the vines’ survival and lead to the discovery of novel biocontrol agents.

“…These techniques not only stimulate growth but also confer stress tolerance, thereby contributing to the attainment of desired crop yields while minimizing environmental impact. [6] This research paper aims into the efficacy of biopriming techniques in augmenting germination and seed vigor in carrot, onion, cauliflower, radish, tomato spinach, fenugreek and pea. This study seeks to elucidate the underlying mechanisms of biopriming and assess its applicability within contemporary horticultural contexts.…”

Seed biopriming induces a physiological condition that promotes germination and uniform seedling emergence. An investigation is carried out on different seeds such as carrot (Daucus carota subsp. Sativus), onion (Allium cepa L.), cauliflower (Brassica oleracea), radish, (Raphanus sativus), tomato (Solanum lycopersicum), spinach (Spinacia oleracea), fenugreek (Trigonella foenum-graecum), and pea (Pisum sativum) to standardise bio-priming with Bacillus siamensis strain NKIT-9 to improve seed germination and seedling vigor index. To optimise the concentration of bio-priming seedlings were bioprimed overnight with Bacillus siamensis strain (NKIT-9) at varied concentrations (0.1mg/ml, 10µg/ml, 0.1µg/ml, and 10ng/ml). Bio-priming with Bacillus siamensis strain NKIT-9 gave highest values of germination percentage and seedling vigor index of carrot (at 0.1mg/ml), onion (at 0.1µg/ml ), cauliflower at 0.1mg/ml, 10µg/ml, and 0.1µg/ml), radish (at0.1mg/ml and 0.1µg/ml), tomato (at 0.1mg/ml), spinach (at 10ng/ml ), fenugreek (at 10ng/ml) and pea (a10ng/ml ) as compared with control. carrot, onion, cauliflower, radish, tomato, spinach, fenugreek, and pea exhibited higher germination percentages (60%, 100%, 100%, 100%, 80%, 90%, 100%, and 60% respectively) and seedling vigor indexes (148 ,720, 910, 880, 525, 580, 990, and 1018 respectively) when compared with control. Therefore, bio-priming with these concentrations is best suited for improving germination rate and seedling vigor of seeds.
