Abstract
Summary Leaves of five nonsucculent scrub species, Carissa spinarum , Maba buxifolia , Gymnosporia emarginata , Flacourtia sepiaria and Dodonaea viscosa exhibited some features of Crassulacean acid metabolism (CAM) under natural semiarid conditions. The occurrence of some characteristics of CAM in these species was exemplified by the nocturnal stomatal conductance, dark carbon assimilation and high activity of phosphoenolpyruvate carboxylase, resulting in the greater degree of dark acidification. The detection of ribulose bisphosphate carboxylase activity and the low δ 13 C values ranged from -24.5 to -29.1 %0 suggested that these five species also utilize reductive pentose phosphate cycle of photosynthesis. The five species exhibiting some CAM characteristics are suggested to be grouped under flexible CAM species which fix carbon dioxide in the light or darkness under natural semiarid conditions. Further, these five species belonged to five diverse dicotyledonous families which hitherto are not known to possess any CAM characteristics.

Summary Ribulose diphosphate (RuDP) and phosphoenolpyruvate (PEP) carboxylases were partially purified from leaves of three C 4 plants: Setaria, Pennisetum and Amaranthus and two C 3 plants: Oryza and Rumex . RuDP carboxylase from C 4 plants had a lower Km for RuDP and HCO 3 − than that of the enzyme from C 3 type. Their reaction velocities were similar in all cases, reflecting the potential of RuDP carboxylase in C 4 plants as well as in C 3 plants. PEP carboxylase from C 4 plants possessed hig...

Summary Malonate inhibited phosphoenolpyruvate carboxylase activity in crude extracts of Setaria italica Beauv. and Pennisetum typhoides S & H leaves. Kinetic studies revealed the competetive inhibition of partially purified phosphoenolpyruvate carboxylase preparation from Setaria italica . Glucose-6-phosphate activated the enzyme. Oxalacetate also competetively inhibited the enzyme and malate in a noncompetetive manner. Results clearly indicated the allosteric nature of phosphoenolpyruvate carb...

The influence of day length, light quality, temperature, drought, and oxygen concentration on gas exchange of Kalanchoe daigremontiana was investigated. The ratio of photosynthesis to dark CO2 fixation with plants under a long-day and short-warm-night regime was 2.0 and under a short-day and long-cool-night regime, 0.2. With drought conditions this value may be less than 0.02. Under low oxygen concentrations high photosynthetic rates of about 20 mg CO2 dm−2 h−1 were observed with a compensation ...

Photosynthetic metabolism in plants capable of Crassulacean acid metabolism (CAM) may involve the net fixation of CO2 in the preceeding dark period or the net fixation of CO2 in the light. The properties of these two carboxylation reactions have been examined and evidence suggesting that dark fixation is essentially a C4-like process and light fixation is essentially a C3-like photosynthetic process is presented.

There are at least 500 species of ferns in Malaysia and Singapore, and these plants form a conspicuous part of the local flora. The reason for their abundance lies in the particularly favorable climate of this part of the world. Holttum (1954) has divided the ferns of Malaysia and Singapore into various classes according to the conditions under which they grow: terrestrial sun ferns, terrestrial shade ferns, epiphytes of sheltered places, epiphytes of exposed places, rock and riverbank ferns, aq...

Tillandsia usneoides, in the common sense a non-succulent plant, exhibits CO2 exchange characterized by net CO2 dark fixation during the night and depression of CO2 exchange during the day. Malate has been demonstrated to accumulate during CO2 dark fixation and to be converted to carbohydrates in light. Thus, T. usneoides exhibits CAM like typical succulents.

We present here the life and research of V. S. Rama Das, a distinguished Indian botanist who specialized in photosynthesis. He was the first to purify chloroplasts that were free of mitochondrial contamination. He then studied C4, C3–C4 intermediate and CAM pathways, as well as their taxonomic distribution in tropical climates. His most valuable legacy is that he, as a philosopher, inspired and guided many students to pursue their research career in India. Also see Narayana and Pullaiah (Eminent...

Photosynthesis research in India can be traced back several thousand years, with the mention of the Sun energizing the plants, which form food for all living creatures on the earth (from the Mahabharata, the great epic, ca. 2600 B.C.) and the report of Sage Parasara (ca. 100 B.C.) on the ability of plants to make their own food, due to their pigments. With the pioneering studies by Sir Jagdish Chandra Bose, work on photosynthesis proceeded steadily during the first half of the 20th century. Some...

The correlation between succulence and Crassulacean acid metabolism (CAM) was investigated in 28 succulent species growing in various habitats throughout North Carolina. Three species (Opuntia compressa, Agave virginica, and Tillandsia usneoides) exhibited diurnal fluctuations in tissue titratable acidity, nighttime uptake of ~14CO2, and a high carbon isotope ratio (~δ13C), all indicators of CAM. Seven species displayed one or two characteristics of CAM in situ yet yielded lower δ13~C values, in...

Summary The influence of two herbicides, paraquat or 2,4,5-T on the in vitro as well as in vivo activity of phosphoenolpyruvate carboxylase from leaves of six nonsucculent scrub species was investigated. The plants, all native and important constituents of the scrubland vegetation, included Carissa spinarum L., Maba buxijolia Cl. , Flacourtia sepiaria Roxb. , Chomelia asiatica O. Kze. , Gymnosporia emarginata Laws. , and Dodonaea viscosa L. The in vitro activity of the enzyme from untreated leav...
