“…However, de novo synthesis and degradation of distinct variants cannot be ruled out. Harsulkar et al 20 reported changes in TI activity in developing seeds of chickpea collected at 20, 40 and 60 days after flowering that correlated with both the disappearance and appearance of TI during the course of seed development.…”

During germination, trypsin inhibitor (TI) content increased relative to total protein and dry weight in cotyledons from two varieties of Vicia faba. These data, together with changes in total protein profiles and amounts, suggest that TI proteins are not hydrolysed in parallel with other seed proteins and dry matter. In contrast, TI content in germinating Cicer arietinum seeds remained constant during the germination period; in this case, however, substantial changes in the total protein profile were not observed. TI isoform analyses indicated that compositional changes occurred during germination in both species.

“…Other plants such as seeds of amaranth (Rodriguez et al, 1993), chickpea (Harsulkar et al, 1997), sunflower (Konarev et al, 2000), maize (Ellatif, 2014), and seeds or leaves of peppers (Montes et al, 2014) have been most extensively studied plants for their proteinase inhibitor contents. The most known proteinase inhibitors are active against digestive proteinases found in animals and microorganisms.…”

“…Previous studies carried out by Harsulkar et al . (1997, 1999) with WBPI had also revealed a decrease of total as well as trypsin-like proteinase activity in H. armigera larvae as a result of which the growth of the early second instar was inhibited. WBTI was also found to significantly lower trypsin activity in the larvae of codling moth, Cydia pomonella (Linnaeus), but the elastase activity was higher than that in water controls (Markwick et al ., 1995).…”

The melon fruit fly, Bactrocera cucurbitae (Coquillett), is a serious agricultural pest which has defied the various control measures employed against it. Protease inhibitors present in plants which have the potential to inhibit the growth and development of associated insect pests can be a possible alternative which can be manipulated for developing resistance in plants to the pest. In the present study, winged bean (Psophocarpus tetragonolobus) protease inhibitor isolated through affinity chromatography was explored for its potential to disrupt the development of melon fruit fly, B. cucurbitae. Different concentrations (12.5, 25, 50, 100, 200, and 400 µg ml−1) of the winged bean protease inhibitor (WBPI) were incorporated into the artificial diet of the second instar (64–72 h old) larvae of B. cucurbitae. The WBPI significantly delayed the larval, pupal, and total development period. The percentage pupation and adult emergence of the treated larvae was reduced as compared with control. The activities of major digestive enzymes (trypsin, chymotrypsin, leucine aminopeptidase, and elastase) decreased significantly in the larvae treated with different concentrations (50, 100, 200, and 400 µg ml−1) of WBPI. The findings reveal that the inhibitor holds considerable promise for the management of the melon fruit fly.
