“…Endophytes are particular microbes that can occupy plant tissues without causing disease symptoms but are involved in mutualistic symbioses with plants, thus exerting multiple beneficial effects, such as growth promotion and disease resistance in host plants 40 , 41 . As an immune strategy that plants employ to respond to exogenous stimuli, cell death has also been reported in endophyte–host interactions.…”

Ferroptosis is an iron-dependent cell death that was discovered recently. For beneficial microbes to establish mutualistic relationships with hosts, precisely controlled cell death in plant cells is necessary. However, whether ferroptosis is involved in the endophyte‒plant system is poorly understood. Here, we reported that endophytic Streptomyces hygroscopicus OsiSh-2, which established a sophisticated and beneficial interaction with host rice plants, caused ferroptotic cell death in rice characterized by ferroptosis- and immune-related markers. Treatments with ferroptosis inhibitors and inducers, different doses of OsiSh-2, and the siderophore synthesis-deficient mutant ΔcchH revealed that only moderate ferroptosis induced by endophytes is essential for the establishment of an optimal symbiont to enhance plant growth. Additionally, ferroptosis involved in a defence-primed state in rice, which contributed to improved resistance against rice blast disease. Overall, our study provides new insights into the mechanisms of endophyte‒plant interactions mediated by ferroptosis and suggests new directions for crop yield promotion.

“…Observation shape of conidia, conidiospores, and phialides used identification book Watanabe [17] with results of observations that conidia were round, conidiophores were insulated and branched upright, each branch contained 3-6 phialides with an oval shape like a pumpkin. According to Ghazanfar et al [5] and Waghunde et al [6], genus Trichoderma spp. has smooth or ellipsoidal conidia, branched conidiophores, insulated hyphae, and philaid shapes like pumpkins.…”

Trichoderma spp. is one of the biocontrol agents that have important benefits for agriculture in Indonesia. Exploration is carried out at PT Bumitama Gunajaya Agro Oil Palm Plantations in high yield blocks. This study aims to identify and determine the isolates of Trichoderma spp. and to find out its in vitro antagonism against Ganoderma spp. Morphological identification of Trichoderma spp. carried out using a trinocular microscope. There were six isolates analyzed based on internal transcribed spacer sequences (ITS) in ribosomal DNA region using PCR technique with ITS 1 and ITS 4. The results of this research showed that Trichoderma spp. original from PT BGA Central Kalimantan has diverse characteristics. Sequencing analysis showed that six isolates were in one group with Trichoderma asperellum isolates T5 (Acc. No. MH809176), IIPR-80 (Acc. No. MK841018) and TV5 (Acc. No. MH393299). Based on the antagonism test, it was found that six isolates were able to inhibit the growth of Ganoderma spp. with an average percentage value is ≥50%.

“…Thus, the evolutionary history of plant and microbes share common origins, and their survival is interdependent. Consequently, the “plant microbiota” has gained more attention that exists within or nearby surfaces of the plant parts [5].…”

Plants and microbes are co-evolved and interact with each other in nature. Plant-associated microbes, often referred to as plant microbiota, are an integral part of plant life. Depending on the health effects on hosts, plant–microbe (PM) interactions are either beneficial or harmful. The role of microbiota in plant growth promotion (PGP) and protection against various stresses is well known. Recently, our knowledge of community composition of plant microbiome and significant driving factors have significantly improved. So, the use of plant microbiome is a reliable approach for a next green revolution and to meet the global food demand in sustainable and eco-friendly agriculture. An application of the multifaceted PM interactions needs the use of novel tools to know critical genetic and molecular aspects. Recently discovered clustered regularly interspaced short palindromic repeats (CRISPR)/Cas-mediated genome editing (GE) tools are of great interest to explore PM interactions. A systematic understanding of the PM interactions will enable the application of GE tools to enhance the capacity of microbes or plants for agronomic trait improvement. This review focuses on applying GE techniques in plants or associated microbiota for discovering the fundamentals of the PM interactions, disease resistance, PGP activity, and future implications in agriculture.
