“…Thiobacillus species were used to generate bio-sulfur, which was investigated as an alternative to managing citrus melanose. It was found that melanose disease severity was lower on bio-sulfur pretreated citrus leaves than on untreated leaves, suggesting that bio-sulfur might be applied as an environmentally friendly alternative to control citrus melanose [153]. Bacillus velezensis CE 100, an effective biocontrol agent, has been used to control D. citri.…”

Citrus melanose is a fungal disease caused by Diaporthe citri F.A. Wolf. It is found in various citrus-growing locations across the world. The host range of D. citri is limited to plants of the Citrus genus. The most economically important hosts are Citrus reticulata (mandarin), C. sinensis (sweet orange), C. grandis or C. maxima (pumelo), and C. paradisi (grapefruit). In the life cycle of D. citri throughout the citrus growing season, pycnidia can be seen in abundance on dead branches, especially after rain, with conidia appearing as slimy masses discharged from the dead twigs. Raindrops can transmit conidia to leaves, twigs, and fruits, resulting in disease dispersion throughout small distances. Persistent rains and warm climatic conditions generally favor disease onset and development. The melanose disease causes a decline in fruit quality, which lowers the value of fruits during marketing and exportation. High rainfall areas should avoid planting susceptible varieties. In this article, information about the disease symptoms, history, geographic distribution, epidemiology, impact, and integrated management practices, as well as the pathogen morphology and identification, was reviewed and discussed.

“…However, various biotic and abiotic stresses still caused high loss rates. Among them, melanose disease, caused by the Diaporthe citri, is a severe fungus disease and can infect all citrus cultivars, accompanied by degrading tastiness and appearance [1]. With the continuous progress of modern biotechnology, especially in recent decades, molecular breeding technology has gradually matured.…”

SBP-box is an important plant-specific transcription factor family and is involved in diverse biological processes. Here, we identified a total of 15 SBP-BOX genes in the important fruit crop sweet orange (Citrus sinensis) and characterized their gene structures, conserved domain and motif, chromosomal location, and cis-acting regulatory elements. SBP genes were classified into four subfamilies based on the amino acid sequence homology, and the classification is equally strongly supported by the gene and protein structures. Our analysis revealed that segmental duplication events were the main driving force in the evolution of CsSBP genes, and gene pairs might undergo extensive purifying selection. Further synteny analysis of the SBP members among sweet orange and other plant species provides valuable information for clarifying the CsSBP family evolutionary relationship. According to publicly available RNA-seq data and qRT-PCR analysis from various sweet orange tissues, CsSBP genes may be expressed in different tissues and developmental stages. Gene expression analysis showed variable expression profiles of CsSBP genes under various abiotic stresses, such as high and low-temperature, salt, and wound treatments, demonstrating the potential role of SBP members in sweet orange response to abiotic stress. Noticeably, all CsSBP genes were also downregulated in sweet orange upon the infection of an important fungal pathogen Diaporthe citri. Our results provide valuable information for exploring the role of SBP-Box in sweet orange.

Leaching experiments of bone-meal phosphorus (P) solubilization by the sulfur-oxidizing bacteria Acidithiobacillus thiooxidans was carried out using the shake-flask methodology. The effects of bone meal dosage, bio-sulfur (bio-S) concentration, and amount of bacterial inoculum on the efficiency of P solubilization were determined. The bone meal was dissolved in bacterially produced sulfuric acid to form "soluble P." An increase in concentration of bio-S as an energy substrate for the acidophilic A. thiooxidans increased the P solubilization efficiency. Upon addition of 5% bio-S, 10% bone meal, and 10% A. thiooxidans to the leach suspension, its pH dropped from 5.22 to 1.92 between days 30 and 40 of the leaching experiment; this resulted in an increase in water-soluble P concentration by 23.8 g P 2 O 5 L -1 . The soluble P concentration in the suspension from the bioleaching experiment was >20 times higher than that in conventional liquid bone-meal fertilizers. Inorganic nutrients, such as N, Ca, and Mg, were also solubilized in the suspension during the bioleaching experiment. The role of bio-S as an energy substrate for acidophilic bacteria to leach P from bone meal during formulation of biofertilizers could potentially be exploited in the management of crop nutrients in organic farming.
