“…The lower occurrence of Ascomycota in livestock manure treatments may be due to the poor adaptation of Ascomycota to changes in the soil environment. Therefore, the return of manure to the farmland alters the soil conditions and affects the adaptability of Ascomycota [57]. In this study, Basidiomycota and Chytridiomycota were negatively correlated with SOC, DOC, ROC, POC, and MBC.…”

The application of organic materials contributes to the sustainable development of agriculture. Increased manure inputs have a fundamental effect on the composition and dynamics of soil organic carbon (SOC). In this study, we conducted a 10-year field experiment in Changchun, Jilin, Northeast China, to investigate the effects of manure addition on soil organic carbon components and soil microorganisms. Specifically, we established four treatments: (i) chemical fertilizer or no addition of manure (CK), (ii) pig manure with chemical fertilizer (ZF), (iii) cow manure with chemical fertilizer (NF), and (iv) chicken manure with chemical fertilizer (JF). The results showed that the JF treatment significantly increased the soil organic carbon (SOC), dissolved organic carbon (DOC), and readily oxidized organic carbon (ROC) content by 20.36%, 105.9%, and 61.32%, respectively, relative to CK. The microbial biomass carbon (MBC) content in JF, ZF, and NF treatments were significantly higher than that of CK, which increased by 107.24%, 116.45%, and 96.71%, respectively. The particulate organic carbon (POC) content in NF and JF treatments differed significantly, increasing by 25.61% and 19.01%, respectively, relative to CK. Redundancy analysis showed that continuous manure application had a positive effect on soil microbial community diversity and abundance, which was favorable for the accumulation of soil carbon. We also found that soil fungi were more sensitive than bacteria to changes in soil carbon composition following manure application. In conclusion, adding different organic materials can better support biodiversity conservation and realize ecosystem services of surface carbon storage and soil conservation. Our results reveal the importance of microbial fixation in soil carbon dynamics according to the different distribution of active organic carbon pools, which will help enhance our understanding of the carbon cycle.

“…Over the past few years, many studies have been conducted to group, classify, and accurately identify different species of Chaetomium, utilizing DNA sequencing as a key tool (Sekhar et al 2018). Very limited studies have been conducted in Arabic countries and Iraq for the genetic characterization of Chaetomium species (Abdullah et al 2015;Abdel-Azeem 2020;Al-Dossary et al 2021;Alfartosy et al 2021).…”

Abstract. Al-Rifaie AA, Ameen MKM. 2023. New endophytic fungal species of Chaetomiaceae (Ascomycota) in Iraq. Biodiversitas 24: 5270-5277. The present study was conducted to isolate and identify some endophytic fungi from vegetable crops in Iraq. Samples of eight vegetable plants, namely Abelmoschus esculentus, Mentha piperita, Vicia faba, Petroselinum sativum, Ocimum basilicum, Lawsonia inermis, Beta vulgaris and Apium graveolens were collected from three regions in Basrah (Abu Al-Khaseeb, Karmat Ali and the Centre of Basrah). Isolation was done by solid culture method and moist culture method. The recovered endophytic fungi were purified and axenic cultures of each isolated species were then identified on the basis of their macro and micro-morphological features. Morphological identification was further confirmed by molecular analysis through DNA extraction and sequencing by PCR amplification of the ITS4 and ITS5 gene primers. Phylogenetic examination revealed that five novel endophytic fungal species related to the family Chaetomiaceae were isolated from vegetable plants, including Chaetomium cucumericola, C. madrasense, Amesia atrobrunnea, A. cymbiformis and Botryotichum verrucosum. Three species, including C. cucumericola, A. cymbiformis and B. verrucosum, were documented for the first time in the Iraqi mycobiota. To the best of our acknowledgment, this study is the first to investigating endophytic fungi from vegetables in Iraq.
