The full-length cDNA encoding a cysteine protease,designated HbCP1, was isolated for the first time from Hevea brasiliensis by the rapid amplification of cDNA ends (RACE) method. HbCP1 contained a 1371 bp open reading frame encoding 457 amino acids.The deduced HbCP1 protein,which showed high
Three isoinhibitors have been isolated to homogeneity from the C-serum of the latex of the rubber tree, Hevea brasiliensis clone RRIM 600, and named HPI-1, HPI-2a and HPI-2b. The three inhibitors share the same amino acid sequence (69 residues) but the masses of the three forms were determined to be
Rubber tree (Hevea brasiliensis Muell. Arg) is an important economic crop in Thailand. Leaf fall and black stripe diseases caused by the aggressive oomycete pathogen Phytophthora palmivora, cause deleterious damage on rubber tree growth leading to decrease of latex production. To gain insights into
Arabidopsis thaliana SAG12, a senescence-specific gene encoding a cysteine protease, is widely used as a molecular marker for the study of leaf senescence. To date, its potential orthologues have been isolated from several plant species such as Brassica napus and Nicotiana tabacum. However, little

43 HbPLCPs representing nine subfamilies or 20 orthologous groups were found in rubber, where paralogs were resulted from the recent WGD and local duplication. Several senescence-associated genes were also identified. Papain-like cysteine proteases (PLCPs) comprise a large family of
Metacaspases, a family of cysteine proteases, have been suggested to play important roles in programmed cell death (PCD) during plant development and stress responses. To date, no systematic characterization of this gene family has been reported in rubber tree (Hevea brasiliensis). In the present
Increases in vascular permeability and angiogenesis are crucial events to wound repair, tumoral growth and revascularization of tissues submitted to ischemia. An increased vascular permeability allows a variety of cytokines and growth factors to reach the damaged tissue. Nevertheless, the
The proteome of Hevea brasiliensis latex has been explored in depth via combinatorial peptide ligand libraries. A total of 300 unique gene products have been identified in this latex, whose proteome has been largely unknown up to the present. In search for unknown allergens, control latex and
This study aimed at screen for antimicrobial activity present in the non-rubber constituents of rubber latex of Hevea brasiliensis against various microbial strains. An antimicrobial protein, hevein was extracted from the bottom fraction after centrifugation and purified by acetone fractionation and
Latex, the milky cytoplasm of highly differentiated cells called laticifers, from Hevea brasiliensis is a key source of commercial natural rubber production. One way to enhance natural rubber production would be to express genes involved in natural rubber biosynthesis by a laticifer-specific
BACKGROUND
Ficus benjamina or weeping fig is a plant used increasingly for indoor decoration that can cause allergic rhinitis and asthma.
OBJECTIVE
We report a clinical and immunologic study in a patient with perennial asthma caused by F. benjamina latex in whom several episodes of angioedema of the
Phytocystatins play multiple roles in plant growth, development and resistance to pests and other environmental stresses. A ramie (Boehmeria nivea L.) phytocystatin gene, designated as BnCPI, was isolated from a ramie cDNA library and its full-length cDNA was obtained by rapid amplification of cDNA
A novel cDNA encoding a bi-functional α-amylase/subtilisin inhibitor (HbASI) was isolated from rubber (Hevea brasiliensis) leaves cultivar RRIM600. The HbASI had strong homology with the soybean trypsin inhibitor (Kunitz) family of protease inhibitors. Its putative amino acid sequence was similar to
A novel cDNA encoding a cysteine proteinase inhibitor or phytocystatin was isolated from Hevea brasiliensis RRIM600 rubber latex cDNA library. The full-length HbCPI obtained from rapid amplification of cDNA ends contains 588 bp. An open reading frame of 306 bp encodes for a protein of 101 amino
The amino acid sequence of rubber elongation factor, a recently discovered protein tightly bound to rubber particles isolated from the commercial rubber tree Hevea brasiliensis, is presented. The role of this protein in rubber elongation and its interaction with prenyltransferase and rubber
