The PA1b (Pea Albumin 1, subunit b) peptide is an entomotoxin extract from Legume seeds with lethal activity on several insect pests, such as mosquitoes, some aphids and cereal weevils. This 37 amino-acid cysteine-rich has been, until now, obtained by biochemical purification or chemical synthesis. In this paper, we present our results for the transient production of in Nicotiana benthamiana agro-infiltration, a yield about 35 µg/g fresh leaves maximum 8 days after infiltration. part PA1...
Albumin 1b peptides (A1b) are small disulfide-knotted insecticidal produced by Fabaceae (also called Leguminosae). To date, their diversity among this plant family has been essentially investigated through biochemical and PCR-based approaches. The availability of high-quality genomic resources for several fabaceae species, which the model species Medicago truncatula (Mtr), allowed a analysis protein aimed at i) deciphering evolutionary history A1b proteins links with A1b-nodulins that short...
Abstract PA1b (Pea Albumin 1, subunit b) peptide is an entomotoxin, extracted from Legume seeds, with a lethal activity towards several insect pests, such as mosquitoes, some aphids and cereal weevils. This toxin acts by binding to the subunits c e of plasma membrane H + -ATPase (V-ATPase) in midgut. In this study, two weevils, sensitive Sitophilus oryzae strain WAA42, resistance ISOR3 insensitive red flour beetle Tribolium castaneum , were used biochemical histological experiments...
Currently, crop protection relies heavily on chemical treatments, which ultimately leads to environmental contamination and pest resistance. Societal public policy considerations urge the need for new eco-friendly solutions. In this perspective, biopesticides are effective alternatives insecticides control of various insect pests. Legumes contain numerous insecticidal proteins aimed at protecting their high nitrogen content from animal/insect predation. Investigating one such protein family...
Abstract Legumes play a central role in various food systems, with significant socio-economic and environmental impacts. Their high protein content, composed mainly of globulins albumins, makes them valuable for human animal feed. Among the is Pea Albumin 1 b (PA1b), 37 amino acid peptide, extracted from seeds pea Pisum sativum . The displays knottin scaffold exhibits potent insecticidal activity against certain insects including cereal weevils mosquitoes. This toxicity attributed to...
