The present study supported the previous reports (Afandi et al 2018) that molecular markers to be considered as promising markers for G. boninense resistance screening oil palm. In addition to the polyisoprenoid pattern in E. guineensis as a potential biochemical marker in response to G. boninense infection (Afandi et al 2019).…”

“…However, genetic diversity on G. boninense is not fully understood. Recently molecular performances showing the grouping of plant resistance to G. boninense occurred in healthy leaves of mature oil palm (Afandi et al 2018). Furthermore, polyisoprenoid carbon chain-length has been shown to be a chemotaxonomic marker for the screening of oil palm resistance to G. boninense (Afandi et al 2019.…”

Abstract. Purba A, Hayati R, Putri LAP, Chalil D, Afandi D, Syahputra I, Basyuni M. 2020. Genetic diversity and structure of Ganoderma boninense isolates from oil palm and other plantation crops. Biodiversitas 21: 451-456. Oil palm is an economically important plant, which one of the most important sources of vegetable oil in the world. However, oil palm plantation and other crops face the treat basal stem rot (BSR) disease by Ganoderma boninense. A study on genetic diversity and structure of G. boninense is therefore needed in order to formulate improved control strategies for this disease. This work aimed to analyze the genetic diversity and structure of the G. boninense isolates derived from different hosts, 131 oil palm (Elaeis guineensis), six rubber (Hevea brasiliensis), three coconuts (Cocos nucifera), and three lontar palm (Borassus flabellifer). Genetic diversity and population structure of G. boninense isolates were investigated using six SSR markers with GenAlex 6.502 software. Results showed that several microsatellite loci indicated specific primary success rates, such as KT124402, KT124399, and KT124394, depicting high polymorphism content (>75%). This result suggested that these markers were equally effective in determining the polymorphisms of G. boninense isolates. A hierarchical analysis of molecular variance (AMOVA) revealed that genetic diversity mostly found among individuals within a population (88%), then among populations (8%), and within individuals (4%).. Phylogeny analysis showed two clusters of Ganoderma isolates. which was considered variation as dissimilar across with origin. The present study indicated that G. boninense from oil palm was predominantly comprised of a genetically distinct individual.

Bud Rot, caused by Phytophthora palmivora, is considered one of the main diseases affecting African oil palm (Elaeis guineensis). In this study, we investigated the in vitro molecular dynamics of the pathogen–host interaction by analyzing gene expression profiles from oil palm genotypes that were either susceptible or resistant to the disease. We observed distinct interactions of P. palmivora with resistant and susceptible oil palms through co-expression network analysis. When interacting with susceptible genotypes, P. palmivora exhibited upregulation of carbohydrate and sulfate transport genes. These genes demonstrated co-expression with apoplastic and cytoplasmic effectors, including cell wall degrading enzymes, elicitins, and RxLR motif effectors. The pathogen manipulated susceptible oil palm materials, exacerbating the response and compromising the phenylpropanoid pathway, ultimately leading to susceptibility. In contrast, resistant materials exhibited control over their response through putative Heat Shock Proteins (HSP) that maintained homeostasis between primary metabolism and biotic defense. Co-expressed genes related to flavonoids, WRKY transcripts, lectin-type receptors, and LRR receptors may play important roles in pathogen control. Overall, the study provides new knowledge of the molecular mechanisms underlying the interaction between E. guineensis and P. palmivora, which can contribute to controlling Bud Rot in oil palms and gives new insights into the interactions of P. palmivora with their hosts.
