Potassium (K) has been recognized as an essential element in intensive agricultural production systems, and deficiency of K usually results in a decrease in crop yields. The utilization of potassium-solubilizing bacteria (KSB) to increase the soluble K content in soil has been regarded as a

BACKGROUND
The rubber tree, Hevea brasiliensis, is a major commercial source of natural rubber. Increasing the rubber yield of rubber trees is a very serious problem since the demands for high quality rubber materials are great. Establishment of a tapping system is based on an estimate of tapping

Water and nutrient are the two main factors limiting Hevea brasiliensis growth and its latex yield. With 17 year-old Clone SCATC 7-33-97 H. brasiliensis as test material, the coupling effects of water and chemical N, P and K fertilizers on latex yield were studied by general orthogonal rotation
Sequestration of toxic Pb(II) ions by chemically treated rubber (Hevea brasiliensis) leaf powder.

Rubber leaf powder (an agricultural waste) was treated with potassium permanganate followed by sodium carbonate and its performance in the removal of Pb(II) ions from aqueous solution was evaluated. The interactions between Pb(II) ions and functional groups on the adsorbent surface were confirmed by

The yield of pollen embryoids from cultured Hevea anthers was increased 4 fold by optimizing the proportion of ammonium nitrate to potassium nitrate in the dedifferentiation medium. For optimal differentiation of pollen embryoids, kinetin, 2,4-D and α-naphtalene acetic acid are required. Anther
The proton gradient across the vacuo-lysosomal membrane of lutoids from the latex of Hevea brasiliensis. I. Further evidence for a proton-translocating ATPase on the vacuo-lysosomal membrane of intact lutoids.

Lutoids (vacuo-lysosomal particles) were isolated from the latex of Hevea brasiliensis. Using flow dialysis with 14C-methylamine uptake as a delta pH probe and 86Rb rubidium + valinomycin distribution for estimations of transmembrane electrical potential, intact lutoids exhibited a delta pH of 1

1. Evidence has been produced for the formation of 5-phosphomevalonate from potassium dl-mevalonate by the latex of Hevea brasiliensis and by reconstituted freeze-dried serum obtained from this latex. 2. The enzyme, mevalonate kinase, catalysing the formation of 5-phosphomevalonate from potassium
A chitinolytic endochitinase and β-N-acetylglucosaminidase-based system from Hevea latex in generating N-acetylglucosamine from chitin.

An endochitinase and β-N-acetylglucosaminidase (NAGase) were purified and characterised from fresh rubber latex serum. These enzymes were used in a total enzyme-based system to produce pure N-acetylglucosamine (NAG) from chitin. The N-terminal amino acid sequences of both purified endochitinase
