In vitro antifungal potential of citral and nanoencapsulated citral against Fusarium oxysporum f.sp. lycopersici

This study aimed to encapsulate citral in chitosan nanoparticles and test its antifungal activity, along with the nanoparticles, against Fusarium oxysporum f.sp. lycopersici (FOL), a soil-borne pathogen causing worldwide yield losses in tomato production. The nanoparticles were characterized using scanning electron microscopy (SEM), FT-IR, encapsulation efficiency (EE), loading capacity (LC), and in vitro release...

Isolation and binary fusion of taro (Colocasia esculeneta (L) Schott.) protoplast: Towards developing somatic hybridization protocol as an alternative to sexual hybridization

Collocasia esculenta (L) Schott. (Taro) genotypes cultivated in Kenya rarely produce flowers, thus improvement via pollination is hindered. Somatic hybridization is an attractive alternative to circumvent flower pollination constrain and hence explored in this study. The aim of this study was to optimize isolation and binary fusion of protoplast obtained from C. esculenta (Dasheen) and C. antiquorum Eddoe) genotypes....

Evaluation of the seroprevalence of okra mosaic virus in Koulikoro, Mali

Mosaic virus disease is transmitted by several types of viruses such as OMD, OYVMV, OLCV, CLCuGV, and CYCrV. Among these viruses, some of them are significant threats to okra production worldwide. To develop an integrated pest management strategy against this disease, this seroprevalence study was conducted at the Rural Polytechnic Institute (RPI) of Katibougou, Koulikoro region, Mali. Symptomatic leaves of okra plants...

Evaluation of runs of homozygosity and genomic endogamy in the Creole breeds Guaymi and Guabala in Panama

The inbreeding coefficient measures the likelihood of identical alleles at a locus in a population due to descent from a common ancestor, highlighting potential negative impacts on health and fitness in both natural and domesticated populations. This study focuses on homozygous segments continuous genomic regions of homozygosity resulting from the inheritance of identical haplotypes from both parents and their role in...
