The rice genome contains at least four separate loci that encode aldolase isozymes. Among these, the aldolase P (AldP) gene, a nuclear gene coding for chloroplast aldolase, is expressed predominantly in the leaf blade mesophyll cells in rice. To dissect promoter elements that regulate such tissue-
Two homologous genes of plastidic fructose-1,6-bisphosphate aldolase (AldP) isozymes were isolated from green leaves of a salt stress-tolerant Nicotiana species, Nicotiana paniculata, by differential screening. The products of the corresponding genes, NpAldP1 and NpAldP2, were 91% identical to each
The Calvin cycle is the initial pathway of photosynthetic carbon fixation, and several of its reaction steps are suggested to exert rate-limiting influence on the growth of higher plants. Plastid fructose 1,6-bisphosphate aldolase (aldolase, EC 4.1.2.13) is one of the nonregulated enzymes comprising
D-Galacturonic acid is the most abundant monosaccharide component of pectic polysaccharides that comprise a significant part of most plant cell walls. Therefore, it is potentially an important nutritional factor for Botrytis cinerea when it grows in and through plant cell walls. The d-galacturonic
Carbon isotope (13C) fractionations occurring during and after photosynthetic CO2 fixation shape the carbon isotope composition (δ13C) of plant material and respired CO2. However, responses of 13C fractionations to diel variation in starch metabolism in the leaf are not fully understood. Here we
To test the hypothesis that the contribution of phosphoribulokinase (PRK) to the control of photosynthesis changes depending on the light environment of the plant, the response of transgenic tobacco (Nicotiana tabacum L.) transformed with antisense PRK constructs to irradiance was determined. In
Genetically engineered tobacco (Nicotiana tabacum L.) with the ability to synthesis glycinebetaine (GB) in chloroplasts was established by introducing the BADH gene for betaine aldehyde dehydrogenase from spinach (Spinacia oleracea L.). The genetic engineering resulted in enhanced tolerance of
