Prospecting the unpredicted potential traits of Cladophialophora chaetospira SK51 to alter photoperiodic flowering in strawberry, a perennial SD plant

Fresh goji (Lycium barbarum L.) berries were treated with high-concentration (50% and 90%) oxygen shocking for 30 min and then stored at 0 ± 0.5 °C for 30 d. Decay, aerobic plate count, firmness, weight loss, total soluble solid (TSS), and titratable acidity (TA) were evaluated during storage. A total of 90% O2 shocking more effectively reduced decay and maintained the weight loss and firmness of goji berries. Subsequently, changes in fungi communities were analyzed using high-throughput sequencing (HTS) in the 90% O2-shocking and control groups. The results showed that 90% O2 shocking retained the richness and diversity of fungi communities and the microbiome was related to the quality properties of the fruit. Thus, we inferred that high oxygen shocking inhibited the development of natural decay and maintained the satisfying quality of goji berries by affecting the fungi community composition, which reduced the growth of pathogenic fungi and harmful saprotrophic fungi in the genera, such as Filobasidium sp., Alternaria sp., and Cladosporium sp. We provide a new insight into the disease development and quality changes during the storage of postharvest goji berries.

“…Various agricultural strategies have been implemented to mitigate the impacts of environmental stresses on crop yield. These approaches include (1) developing and producing new cultivars that are tolerant to stresses through breeding programs and genetic engineering [7]; (2) altering planting and harvesting time management [8,9]; (3) optimizing water irrigation [10,11]; and (4) developing efficient bio-fertilizers and bio-pesticides to improve plant productivity and soil health [12][13][14]. Among these, harnessing plant-microbe interactions to develop efficient bio-fertilizers for specific conditions is recognized as a crucial approach to addressing agricultural challenges.…”

“…Plant endosymbionts, such as dark septate endophytic (DSEs) fungi, known as root colonizers, are recognized for their role in improving plant health and resilience under stress to both biotic and abiotic factors via several pathways [8,[15][16][17][18]. DSEs belong to the Ascomycota phylum and have specialized hyphae that produce a large amount of melanin and are divided into separate segments.…”

The highly virulent Fusarium oxysporum formae speciales (f.sp.) fragaria causes Fusarium wilt and significant losses in the strawberry agroindustry. The effective control strategies for this phytopathogen have yet to be developed. We aimed to evaluate the bioefficacy of root-colonizer dark septate endophytic fungi (DSEs) in controlling Fusarium wilt in simultaneous with biostimulation activities. Three out of nineteen tested isolates were selected because of their superior bioefficacy in regulating disease suppression and growth promotion. Notably, the highest level of disease suppression was marked at 90.48%, followed by 85.71% and 61.90% with the inoculation of these three selected isolates i.e., SK51, SK47, and SK48, respectively. The fungal isolates were identified based on partial SSU, LSU, and ITS as DSE fungus Cladophialophora chaetospira strain SK51, Exophiala sp. strain SK47, and E. pisciphila strain SK48. Our findings showed that C. chaetospira SK51 exhibited significant potential in promoting plant growth and suppressing diseases. It significantly enhanced various plant growth factors, such as the total plant biomass, the content of chlorophyll (SPAD), the formation of flower buds, and the development of fruits compared to both non-inoculated control and the other two DSE-inoculated plants. Our study provides new findings and perspectives on the use of the DSE, particularly C. chaetospira SK51 as a bioprotectant and biostimulant for enhancing the development, flower bud formation, and fruit development in strawberry plants.
