Cloning of a class III acidic chitinase from chickpea.
From chickpea (Cicer arietinum L.), one ,f3-1,3-glucanase and two chitinases were purified and characterized (Vogelsang and Barz, 1993). The P-l,S-glucanase and one chitinase each with a basic isoelectric point (class I) were shown to be localized in vacuoles, whereas the second class 111 acidic chitinase revealed an extracellular localization (Mackenbrock et al., 1992). Here we report on the c...
متن کاملFloral Nectar Guide Patterns Discourage Nectar Robbing by Bumble Bees
Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists. Generally, bees access nectar via the floral limb, transporting pollen through contact with the plant's reproductive structures; however bees some...
متن کاملScChi, Encoding an Acidic Class III Chitinase of Sugarcane, Confers Positive Responses to Biotic and Abiotic Stresses in Sugarcane
Chitinases (EC 3.2.2.14), expressed during the plant-pathogen interaction, are associated with plant defense against pathogens. In the present study, a positive correlation between chitinase activity and sugarcane smut resistance was found. ScChi (GenBank accession no. KF664180), a Class III chitinase gene, encoded a 31.37 kDa polypeptide, was cloned and identified. Subcellular localization rev...
متن کاملcDNA cloning and expression of a class II acidic chitinase from sweet orange.
A citrus cDNA encoding a class II acidic chitinase was isolated from a nonembryogenic cell line of sweet orange using the tobacco cDNA clone PROB3. Northern blot analysis revealed that the corresponding mRNA is expressed in young, green bark but not in leaves, roots, or flavedo.
متن کاملCaffeine in floral nectar enhances a pollinator's memory of reward.
Plant defense compounds occur in floral nectar, but their ecological role is not well understood. We provide evidence that plant compounds pharmacologically alter pollinator behavior by enhancing their memory of reward. Honeybees rewarded with caffeine, which occurs naturally in nectar of Coffea and Citrus species, were three times as likely to remember a learned floral scent as were honeybees ...
