“…41 (±)-Ganocapenoid D (29 and 30), with significant ABTS radical scavenging activity, moderate DPPH radical scavenging activity, and moderate neurite outgrowth-promoting activity, were generated from G. capense and G. oregonense, and were proposed absolute stereochemistry by CD comparisons. 43,44 The investigation of G. oregonense also resulted in the isolation of (±)-oregonensins A and B (25)(26)(27)(28), chizhine E (31 and 32) and applanatumol U (33 and 34), and these compounds were developed significant ABTS radical scavenging and moderate DPPH radical scavenging activities. 44 The absolute configurations of (±)-oregonensin A (25 and 26) were defined by specific optical rotation comparisons, and as for (±)-oregonensin B (27 and 28), the chiral analysis showed two peaks, but the chiral separation was not performed, thus, the aboslute stereochemistry of (±)-oregonensin B (27 and 28) have not yet been established.…”

“…Meroterpenoid structures from different fungi species of the same genus may be structurally related; however, they also conspicuously vary in the structural category. So far, over 200 species in the genus Ganoderma have been identified worldwide, but only several important species are serving medical use in folklore or authorized in pharmacies 27 . Although the limited species growing in regions with a medicinal culture and the more promising the proven species through practice might be the main reasons that led to the focus on these species, the discrepancies in chemical composition between species cannot be ignored.…”

Ganoderma meroterpenoids (GMs) containing 688 structures to date were discovered to have multiple remarkable biological activities. 65.6% of meroterpenoids featuring stereogenic centers from Ganoderma species are racemates. Further, GMs from different Ganoderma species seem to have their own characteristics. In this review, a comprehensive summarization of GMs since 2000 is presented, including GM structures, structure corrections, biological activities, physicochemical properties, total synthesis, and proposed biosynthetic pathways. Additionally, we especially discuss the racemic nature, species‐related structural distribution, and structure–activity relationship of GMs, which will provide a likely in‐house database and shed light on future studies on GMs.

“…Ganoderma is a genus of polypore fungi. It belongs to phylum Basidiomycota, class Agaricomycetes, order Polyporales and family Ganodermataceae ( Du et al, 2019 ). In general, they are recognised by ellipsoid to ovoid, double-walled and truncate basidiospores ( Audet 2010 & Karsten 1881 ).…”

The rapid expansion of oil palm (OP) has led to its emergence as a commodity of strategic global importance. Palm oil is used extensively in food and as a precursor for biodiesel. The oil generates export earnings and bolsters the economy of many countries, particularly Indonesia and Malaysia. However, oil palms are prone to basal stem rot (BSR) caused by Ganoderma boninense which is the most threatening disease of OP. The current control measures for BSR management including cultural practices, mechanical and chemical treatment have not proved satisfactory. Alternative control measures to overcome the G. boninense problem are focused on the use of biological control agents and many potential bioagents were identified with little proven practical application. Planting OP varieties resistant to G. boninense could provide the ideal long-term solution to basal stem rot. The total resistance of palms to G. boninense has not yet been reported, and few examples of partial resistances have been observed. Importantly, basidiospores are now recognized as the method by which the disease is spread, and control methods require to be revaluated because of this phenomenon. Many methods developed to prevent the spread of the disease effectively are only tested at nursery levels and are only reported in national journals inhibiting the development of useful techniques globally. The initial procedures employed by the fungus to infect the OP require consideration in terms of the physiology of the growth of the fungus and its possible control. This review assesses critically the progress that has been made in BSR development and management in OP.

“…Detection of pests and diseases The use of remote sensors allows evaluating the state of the palms to obtain an early diagnosis of diseases or infestation of pests based on the symptoms shown in certain places [5,34,35]. Reference [36] has proposed the common hypothesis that oil palm infected with Ganoderma boninense shows observable symptoms at an early stage, and conducted a study to discriminate the oil palm affected by this disease. Among these, a portable field hyperspectral instrument was used to differentiate healthy and infected oil palm [37].…”

Generating the Baseline in the Early Detection of Bud Rot and Red Ring Disease in Oil Palms by Geospatial Technologies

Oil palm cultivation in Ecuador is important for the agricultural sector. As a result of it, the country generates sources of employment in some of the most vulnerable zones; it contributes 0.89% of the gross domestic product and 4.35% of the agricultural gross domestic product. In 2017, a value of USD $252 million was generated by exports, and palm contributed 4.53% of the agricultural gross domestic product (GDP). It is estimated that 125,000 hectares of palm were lost in the Republic of Ecuador due to Red Ring Disease (RRD) and specifically Bud Rot (BR). The current study aimed to generate an early detection of BR and RRD in oil palm. Image acquisition has been performed using Remotely Piloted Aircraft System (RPAS) with Red, Green, and Blue (RGB) cannons, and multispectral cameras, in study areas with and without the presence of the given disease. Hereby, we proposed two phases. In phase A, a drone flight has been conducted for processing and georeferencing. This allowed to obtain an orthomosaic that serves as input for obtaining several vegetation indices of the healthy crop. The data and products obtained from this phase served as a baseline to perform comparisons with plantations affected by BR and RRD and to differentiate the palm varieties that are used by palm growers. In phase B, the same process has been applied three times with an interval of 15 days in an affected plot, in order to identify the symptoms and the progress of them. A validation for the diseases detection has been performed in the field, by taking Global Positioning System (GPS) points of the palms that presented symptoms of BR and RRD, through direct observation by field experts. The inputs obtained in each monitoring allowed to analyze the spatial behavior of the diseases. The values of the vegetation indices obtained from Phase A and B aimed to establish the differences between healthy and diseased palms, with the purpose of generating the baseline of early responses of BR and RRD conditions. However, the best vegetation index to detect the BR was the Visible Atmospherically Resistant Index (VARI).
