In this study, we investigated whether prolonged exposure to MoMo30 exerts selective pressure on HIV-1 and induces mutations in the viral envelope (env) gene. T-lymphocyte cells were infected with HIV-1NL4-3 and continuously treated with MoMo30 over a 24-day period. Viral RNA was isolated at regular intervals, and env genes were sequenced using the Illumina platform. RNA sequence variant calling was performed using iVar, which uses a frequency-based binomial test with a default allele frequency threshold of 3% and a minimum base quality of 20 and applies Bonferroni correction for multiple testing. The infectivity of the MoMo30-exposed virus was assessed using MAGI-CXCR4 cells, visualized by \u03b2-galactosidase staining, and compared to untreated controls. Statistical significance was determined via two-way ANOVA. MoMo30-treated HIV-1 exhibited multiple detrimental mutations in gp120 and gp41, including missense, nonsense, and frameshift changes. Notably, 32% of N-linked glycosylation sites were deleted in the treated virus, while no such changes were observed in controls. Functionally, the MoMo30-treated virus demonstrated a sixfold reduction in infectivity compared to untreated HIV-1NL4-3. These findings suggest that MoMo30 imposes genetic pressure on HIV-1NL4-3, selecting for mutations that reduce viral fitness.<\/jats:p>","DOI":"10.3390\/v17070910","type":"journal-article","created":{"date-parts":[[2025,7,2]],"date-time":"2025-07-02T07:55:43Z","timestamp":1751442943000},"page":"910","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Plant Lectin, MoMo30, Pressures HIV-1 to Select for Variants with Deleted N-Linked Glycosylation Sites"],"prefix":"10.3390","volume":"17","author":[{"given":"Morgan I.","family":"Coleman","sequence":"first","affiliation":[{"name":"Department of Microbiology, Biochemistry and Immunology, Morehouse School of Medicine, 720 Westview Dr. SW, Atlannta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8964-3381","authenticated-orcid":false,"given":"Mahfuz B.","family":"Khan","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Biochemistry and Immunology, Morehouse School of Medicine, 720 Westview Dr. SW, Atlannta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erick","family":"Gbodossou","sequence":"additional","affiliation":[{"name":"PROMETRA International, Dakar-Etoile BP 6134, Senegal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amad","family":"Diop","sequence":"additional","affiliation":[{"name":"Malango Traditional Healers Association, Fatick BP 1763, Senegal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kenya","family":"DeBarros","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Biochemistry and Immunology, Morehouse School of Medicine, 720 Westview Dr. SW, Atlannta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3999-3076","authenticated-orcid":false,"given":"Vincent C.","family":"Bond","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Biochemistry and Immunology, Morehouse School of Medicine, 720 Westview Dr. SW, Atlannta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Virginia","family":"Floyd","sequence":"additional","affiliation":[{"name":"Department of Community Health and Prevention, Morehouse School of Medicine, 720 Westview Dr. SW, Atlanta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kofi","family":"Kondwani","sequence":"additional","affiliation":[{"name":"Department of Community Health and Prevention, Morehouse School of Medicine, 720 Westview Dr. SW, Atlanta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Valerie Montgomery","family":"Rice","sequence":"additional","affiliation":[{"name":"Office of the President, Morehouse School of Medicine, 720 Westview Dr. SW, Atlanta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7698-4841","authenticated-orcid":false,"given":"Michael D.","family":"Powell","sequence":"additional","affiliation":[{"name":"Department of Microbiology, Biochemistry and Immunology, Morehouse School of Medicine, 720 Westview Dr. SW, Atlannta, GA 30310, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,27]]},"reference":[{"key":"ref_1","unstructured":"Swinkels, H.M., Nguyen, A.D., and Gulick, P.G.
