Abstract Presence of the integrated endogenous banana streak virus (eBSV) in B genome plantain (AAB) is a major challenge for breeding and dissemination hybrids. As eBSV activates into infectious viral particles under stress, progenitor Musa balbisiana its derivants, having at least one genome, cannot be used as parents crop improvement. Here, we report strategy to inactivate by editing sequences. The regenerated genome-edited events Gonja Manjaya showed mutations targeted sites with...
Abstract Carotenoid cleavage dioxygenases (CCDs) form hormones and signaling molecules. Here we show that a member of an overlooked plant CCD subfamily from rice, name Zaxinone Synthase (ZAS), can produce zaxinone, novel apocarotenoid metabolite in vitro. Loss-of-function mutants ( zas ) contain less exhibit retarded growth showed elevated levels strigolactones (SLs), hormone determines architecture, mediates mycorrhization facilitates infestation by root parasitic weeds, such as Striga spp....
Banana (Musa spp.) is an important staple food crop and a source of income for resource-poor farmers in more than 136 tropical sub-tropical countries with annual production 155 million tons (FAOSTAT, 2018). Many diseases severely constrain banana production, particularly where many pathogens co-exist (Tripathi et al., 2020). Xanthomonas wilt (BXW) caused by campestris pv. musacearum (Xcm) considered among the most destructive East Central Africa 2009). All cultivated varieties are...
Both strigolactones (SLs) and abscisic acid (ABA) biosynthetically originate from carotenoids. Considering their common origin, the interaction of these two hormones at biosynthetic and/or regulatory level may be anticipated. Here we show that, in rice, drought simultaneously induces SL production root, ABA expression genes shoot. Under control conditions, concentration was higher shoots rice mutants dwarf10 (d10) d17 than wild-type plants, while a similar trend observed for perception...
The clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system enables precision editing of the genome many plant species. Developing robust gene tools in banana and plantain would pave way for improvement these crops. Here, we developed efficient CRISPR/Cas9 protocol using multiple gRNAs targeting phytoene desaturase (PDS) gene. construct containing two was delivered into embryogenic cell suspension cultures cultivar ‘Sukali Ndiizi’ ‘Gonja...
Abstract Banana is a major staple food crop feeding more than 500 million people in tropical and subtropical countries. Its production largely constrained by diseases pests addition to other factors such as declining soil fertility, narrow genetic diversity germplasm, inadequate availability of clean planting material. The impact climate change, particularly rise temperature drought, predicted affect adversely due direct effect on plant agronomy also influence pathogens, pests, their...
Strigolactones (SLs) are a new class of phytohormones that also act as germination stimulants for root parasitic plants, such Striga spp., and branching factors symbiotic arbuscular mycorrhizal fungi. Sources natural SLs very limited. Hence, efficient simple SL analogs needed elucidating SL-related biological processes well agricultural applications. Based on the structure non-canonical methyl carlactonoate, we developed new, easy to synthesize series analogs, termed phenlactonoates (MPs),...
Cassava ranks fifth among the starch producing crops of world, its annual bioethanol yield is higher than for any other crop. cultivar KU50, most widely grown non-food purposes susceptible to Sri Lankan cassava mosaic virus (SLCMV). The objective this work was engineer resistance SLCMV by RNA interference (RNAi) in order increase biomass yield, an important aspect production. Here, we produced transgenic KU50 lines expressing dsRNA homologous region between AV2 and AV1 DNA A SLCMV. High...
To Editor Yam (Dioscorea spp.) is a multi-species tuber crop providing food and income to millions of people worldwide, particularly in Africa (Price et al., 2016). The 'yam belt' West Africa, including Nigeria, Benin, Togo, Ghana, Côte d'Ivoire, accounts for 92% 72.6 million tons global yam production (FAOSTAT, 2018). Despite the economic importance, cultivation plagued by several biotic abiotic factors. genetic improvement via conventional breeding has not achieved substantial progress...
The African BioGenome Project (AfricaBP) is a Pan-African initiative aimed at improving food systems and biodiversity conservation through genomics while ensuring equitable data sharing benefits. Open Institute the knowledge exchange platform of AfricaBP which aims to bridge local gaps in bioinformatics enable infrastructural developments. In 2024, advanced this mission by organising 31 workshops that attracted more than 3500 registered attendees trained 380 researchers genomics,...
Summary Nodulins and nodulin‐like proteins play an essential role in the symbiotic associations between legumes Rhizobium bacteria. Their extends beyond leguminous species, as numerous proteins, including early (ENODL), have been identified various non‐leguminous plants, implying their involvement functions nodulation, such nutrient transport growth modulation. Some ENODL associated with plant defense against pathogens, evident banana infected Xanthomonas campestris pv. musacearum (Xcm)...
Cassava (Manihot esculenta Crantz) is cultivated in tropical and subtropical regions for its edible tuberous roots minimally leaves. It provides food revenue to over eight hundred million people particularly Africa. Generally, cassava drought-tolerant, sheds leaves drought conditions resulting significantly lower yields. management strategies need focus on maximizing the utilization of molecular tools crop establishment yield. Developing produce cultivars with tolerance vital extending yield...
