“…Here, CpaTI, isolated from Crotalaria pallida seeds, belonging to the Papilionoideae or Faboideae subfamily, weakly inhibited other serine proteinases, such as elastase and chymotrypsin, and was active against papain, a cysteine proteinase. So far, only three related Kunitz-type inhibitors, all belonging to the Mimosoideae sub-family, were found to be active against papain-like enzymes, and were strongly active against enzymes from the midgut of bruchid larvae [19,20,47], suggesting that Kunitz-type inhibitors from both subfamilies are bifunctional inhibitors.…”

“…Serine proteinases [24] acted on H. armigera, H. virenscens and L. cuprina, in which SKTI was the most effective among the inhibitors tested [54][55][56][57][58][59]. ApTI (Adenanthera pavonina trypsin inhibitor) and DMTI-II (Dimorphandra mollis trypsin inhibitor) inhibited 84% [20] and 80% [47] of the digestive trypsin-like enzymes of C. maculatus, a Colepteran (Bruchidae). These results are similar to those found for CpaTI.…”

“…Two recent studies have shown the effect of a trypsin inhibitor in feeding trial assays for C. maculatus. DMTI-II and ApTI from D. mollis [47] and A. pavonina seeds [20], respectively, were strongly active in the bioassays with LD 50 values between 0.5 and 1%. These Kunitz-type inhibitors also showed an unusual property of interaction with a chitin matrix column.…”

Salicylic acid and ethylene signaling pathways are involved in production of rice trypsin proteinase inhibitors induced by the leaf folder Cnaphalocrocis medinalis (Guenée)

The roles of signaling pathways in the production of trypsin proteinase inhibitors (TrypPIs) in rice infested by the leaf folder (LF) Cnaphalocrocis medinalis were studied. Infestation by LF increased TrypPI levels in the leaves of rice plants at the tillering, booting and flowering stages but decreased TrypPI levels at the ripening stage; TrypPI levels in rice stems did not increase at any developmental stage. Infestation by LF at the tillering stage systemically increased TrypPI levels in leaves but not in stems; it also enhanced salicylic acid (SA) levels in leaves and stems, and the ethylene level released from plants. However, LF infestation did not increase JA concentrations. Exogenous application of SA or ethylene enhanced TrypPI levels in the leaves and stems of plants at the tillering stage, whereas treatment with both SA and ethylene induced lower levels of TrypPIs than treatment with SA or ethylene alone, suggesting an antagonistic effect of SA and ethylene on TrypPIs induction. The results suggest that both SA and ethylene signaling pathways are involved in the production of TrypPIs in rice induced by LF; moreover, the antagonistic effect of SA and ethylene may explain the changes in TrypPI levels seen at different plant developmental stages and in different organs.rice, Cnaphalocrocis medinalis, jasmonic acid, salicylic acid, ethylene, trypsin proteinase inhibitor, herbivore-induced defense response Citation:Wang X, Hu L C, Zhou G X, et al.

Plant antiherbivore defenses in Fabaceae species of the Chaco

2016

View full text Add to dashboard Cite

The establishment and maintenance of plant species in the Chaco, one of the widest continuous areas of forests in the South American with sharp climatic variations, are possibly related to biological features favoring plants with particular defenses. This study assesses the physical and chemical defenses mechanisms against herbivores of vegetative and reproductive organs. Its analyses of 12 species of Fabaceae (Leguminosae) collected in remnants of Brazilian Chaco shows that 75% present structural defense characters and 50% have chemical defense -defense proteins in their seeds, like protease inhibitors and lectins. Physical defenses occur mainly on branches (78% of the species), leaves (67%), and reproductive organs (56%). The most common physical characters are trichomes and thorns, whose color represents a cryptic character since it does not contrast with the other plant structures. Defense proteins occur in different concentrations and molecular weight classes in the seeds of most species. Protease inhibitors are reported for the first time in seeds of: Albizia niopoides, Anadenanthera colubrina, Mimosa glutinosa, Prosopis rubriflora, and Poincianella pluviosa. The occurrence of physical and chemical defenses in members of Fabaceae indicate no associations between defense characters in these plant species of the Chaco.Keywords: structural characters, protease inhibitors, lectins, defense mechanisms. Defesas das plantas anti-herbivoria em espécies de Fabaceae do Chaco ResumoO estabelecimento e a manutenção de espécies no Chaco, uma planície semi-árida da América do Sul com variações climáticas importantes, possivelmente estão relacionados a características biológicas que favorecem as plantas detentoras de defesas particulares. Este estudo teve como objetivos avaliar os mecanismos de defesa física e química anti-herbivoria em órgãos vegetativos e reprodutivos. Analisamos 12 espécies da família Fabaceae (Leguminosae) obtidas em remanescentes de Chaco brasileiro. Observamos que 75% das espécies estudadas apresentam atributo de defesa física e 50% possuem defesa química -proteínas de defesa nas sementes, como inibidores de protease e lectinas. As defesas físicas ocorrem principalmente nos ramos (78% das espécies), nos órgãos reprodutivos (56% das espécies) e nas folhas (67%). Os atributos físicos mais frequentes são tricomas e espinhos, cuja coloração não contrastante com as demais estruturas das plantas representa um caráter críptico. Proteínas de defesa ocorrem nas sementes da maioria das espécies, com diferentes concentrações e classes de pesos moleculares. Inibidores de protease nas sementes estão sendo relatados pela primeira vez em: Albizia niopoides, Anadenanthera colubrina, Mimosa glutinosa, Prosopis rubriflora e Poincianella pluviosa. A ocorrência de defesas física e química entre os membros de Fabaceae indica que não há associações entre as características de defesa das espécies de plantas avaliadas no Chaco.Palavras-chave: características estruturais, inibidores de protease, lectinas, mecanismo...
