Cucumis melo "Meloncella fasciata" is cultivated and appreciated locally for its unripe fruits. Seed production of these landraces rely on local farmers but heterogeneity limits rapid scalability this crop. Plant micropropagation techniques may be an alternative method propagation their use limited by genetic instability. We concentrated organogenesis from cotyledonary nodes, applying the plant growth regulator 6-benzylaminopurine (BAP) combined with antibiotic cefotaxime to reduce negative effects high cytokinin doses. It was observed that antibiotic, in addition limiting contamination, has a stimulatory effect regeneration several species including melon. Multiple shoot achieved explants within 30 days cultivation. Explants regenerated adventitious shoots all concentrations BAP cefotaxime, however efficiency varied significantly. Cefotaxime at dose 500 mg/L 0.5 induced comparable higher doses BAP. Reducing concentration beneficial development, since excessive can induce somaclonal variation. Thanks reduced quantity BAP, no tetraploid cells could plants. conclude integrated process providing multiple advantages contamination control chromosomal

Distribution and pathogenicity of Cicer arietinum infecting fungi in Tunisian agricultural lands

Botany, Journal Year: 2025, Volume and Issue: 103, P. 1 - 13

Chickpea ( Cicer arietinum L.) ranks as one of the world’s leading legume crops, valued for its protein-packed edible seeds and contribution to soil fertility. However, chickpea cultivation encounters various biotic stresses, particularly fungal diseases, significantly impacting productivity. In this study, a collection 178 fungi, belonging six geographical locations, was isolated from root aerial tissues showing signs infection. The pathogenicity tests revealed that 75% these fungi exhibited varying degrees pathogenicity, with very pathogenic representing largest fraction (39%). Among these, 20 highly isolates were identified, eight different morphological types. Using rDNA ITS-sequencing, we classified into three genera five distinct species, including four newly identified pathogens chickpea: Fusarium foetens, boothii, Macrophomina pseudophaseolina, Aspergillus alliaceus. Molecular characterization analysis highlighted prevalence genus species F. foetens across all investigated sites. These results provide key insights pathogens, aiding crop management.
