Many plants contain latex that exudes when leaves are damaged, and a number of proteins enzymes have been found in it. The roles those as yet poorly understood. We papain, cysteine protease the Papaya tree (Carica papaya, Caricaceae), is crucial factor defense papaya against lepidopteran larvae such oligophagous Samia ricini (Saturniidae) two notorious polyphagous pests, Mamestra brassicae (Noctuidae) Spodoptera litura (Noctuidae). Leaves laticiferous plants, including wild fig, Ficus...
The brown planthopper (BPH) is the most serious insect pest of rice in Asia. indica cultivar ADR52 carries two BPH resistance genes, BPH26 (BROWN PLANTHOPPER RESISTANCE 26) and BPH25. Map-based cloning revealed that encodes a coiled-coil-nucleotide-binding-site–leucine-rich repeat (CC–NBS–LRR) protein. mediated sucking inhibition phloem sieve element. was identical to BPH2 on basis DNA sequence analysis feeding ability BPH2-virulent biotype BPH. widely incorporated elite cultivars...
Since ancient times, mulberry leaves ( Morus spp.) have been used to rear the silkworm Bombyx mori . Because grows well on leaves, toxicities and defensive activities of these against herbivorous insects overlooked. Here we show that are highly toxic caterpillars other than B. , because ingredients latex, a milky sap exuded from leaf veins. The toxicity was lost when latex eliminated artificial diets containing showed toxicity. Mulberry contained very high concentrations alkaloidal...
To compare changes in platelets stored the new di‐n‐decyl phthalate (DnDP)‐plasticized polyvinyl chloride (PVC) bag with those a di‐(2‐ethylhexyl) (DEHP)‐plasticized PVC bag, single‐donor apheresis platelet concentrates (PCs), 133 ± 11 × 10 7 per ml (n = 7), were 94 3 of plasma 1‐liter surface area 44 7.1 cm 2 platelets. Oxygen and carbon dioxide gas diffusion properties PVC‐DnDP films respectively, 1.6 times standard PVC‐DEHP films. The amounts DnDP leaked into PCs low at 0.58 0.06 mg after...
Rice GRH2 confers enhanced resistance to green rice leafhoppers (GRH), Nephotettix cincticeps Uhler. A pyramided line carrying and GRH4 (TGRH29) showed strong GRH insects compared with a near-isogenic (TGRH11), although alone did not confer any GRH. To explore the effects of on resistance, we investigated transcriptional response plants infestation using DNA microarray analysis. The expression large number genes encoding pathogenesis-related proteins, lipoxygenases, terpene synthase (TPS)...
The leaf beetle Ophraella communa is an oligophagous insect that infests several asteraceous plants, especially ragweed Ambrosia artemisiifolia, in fields of Japan. feeding responses O. to methanolic extracts 11 genera and 17 species plants were examined determine whether preference depended on chemicals the plants. 8 stimulated communa, but other 9 showed no activity. Two triterpenoids (α-amyrin acetate β-amyrin acetate) two caffeic acid derivatives (chlorogenic 3,5-dicaffeoylquinic acid)...
Carotenogenesis in Nocardioform actinomycete Rhodococcus rhodochrous was investigated using carotenogenesis mutants and inhibitors, a postulated pathway proposed. At the end of synthesis, fatty acid or mycolic esterified by different esterases to same C-6 hydroxyl group β-D-glucoside.
Norin-PL3 and Norin-PL4 are rice (Oryza sativa L.) breeding lines that carry a brown planthopper (BPH) resistance gene. was bred by introgressing BPH1 derived from the Indica Group variety Mudgo into Japonica rice, whereas BPH2 IR 1154-243 rice. To detect alleles donor varieties in these lines, we developed simple method to create graphical genotypes using part of InDel information obtained short-read next-generation sequencing system. In Norin-PL3, chromosomal regions were found on...
