“…Strigolactones (SLs) inhibit shoot branching and are released by plant roots into the rhizosphere to attract symbiotic mycorrhizal fungi (AM), particularly under phosphate (Pi) starvation, (Al-Babili and Bouwmeester, 2015; Fiorilli et al, 2019; Wang et al, 2023a). However, SLs also act as germination stimulants for root-parasitic weeds, such as Orobanche and Striga spp.…”

The yield of pearl millet, a resilient cereal crop crucial for African food security, is severely impacted by the root parasitic weed Striga hermonthica, which requires host-released strigolactones (SLs) for seed germination. Herein, we identified four SLs present in the Striga-susceptible line SOSAT-C88-P10 (P10), but absent in the resistant 29Aw (Aw). We generated chromosome-scale genome assemblies including four gapless chromosomes for each line. We found the Striga-resistant Aw lacks a 0.7 Mb genome segment containing two putative CARLACTONOIC ACID METHYLTRANSFERASE1 (CLAMT1) genes. Upon transient expression, P10CLAMT1b produced methyl carlactonoate (MeCLA), an intermediate in SL biosynthesis. Feeding Aw with MeCLA resulted in the production of two P10-specific SLs. Screening a diverse pearl millet panel confirmed the pivotal role of the CLAMT1 section for SL diversity and Striga susceptibility. Our results reveal a reason for Striga susceptibility in pearl millet and pave the way for generating resistant lines through marker-assisted breeding or direct genetic modification.

“…The communication between the root microbiome and plant roots is an intricate and dynamic process that entails an array of chemical, molecular, and physical interactions [ 13 ]. These interactions are controlled by a wide range of specialized exudates and metabolites [ 14 ]. Around or within the plant roots, there are several of these molecules whose concentration varies according to the distance from the point of emission.…”

Communication between Plants and Rhizosphere Microbiome: Exploring the Root Microbiome for Sustainable Agriculture

Plant roots host numerous microorganisms around and inside their roots, forming a community known as the root microbiome. An increasing bulk of research is underlining the influences root-associated microbial communities can have on plant health and development. However, knowledge on how plant roots and their associated microbes interact to bring about crop growth and yield is limited. Here, we presented (i) the communication strategies between plant roots and root-associated microbes and (ii) the applications of plant root-associated microbes in enhancing plant growth and yield. This review has been divided into three main sections: communications between root microbiome and plant root; the mechanism employed by root-associated microbes; and the chemical communication mechanisms between plants and microbes and their application in plant growth and yield. Understanding how plant root and root-associated microbes communicate is vital in designing ecofriendly strategies for targeted disease suppression and improved plant growth that will help in sustainable agriculture. Ensuring that plants become healthy and productive entails keeping plants under surveillance around the roots to recognize disease-causing microbes and similarly exploit the services of beneficial microorganisms in nutrient acquisition, stress mitigation, and growth promotion.
