Crassulacean acid metabolism (CAM) has evolved independently on dozens of occasions and is now found in over 7% of plant species. In this study, the leaf structure of a phylogenetically diverse assemblage of 18 CAM plants was compared with ...
Distribution of crassulacean acid metabolism in orchids of Panama: evidence of selection for weak and strong modes [0.03%]

Crassulacean acid metabolism (CAM) is one of three metabolic pathways found in vascular plants for the assimilation of carbon dioxide. In this study, we investigate the occurrence of CAM photosynthesis in 200 native orchid species from Pana...
Welwitschia mirabilis: CAM or not CAM - what is the answer? [0.03%]
Welwitschia mirabilis：是或不是CAM植物——答案是什么？

Dieter J von Willert et al.
After more than 20 years of extensive study we found clear evidence that Welwitschia mirabilis Hook.f. is able to take up CO2 at night in both of its natural ecosystems, the Namib desert and the Mopane savannah, and hence should be classifi...
Carbon isotope composition and water-use efficiency in plants with crassulacean acid metabolism [0.03%]

The physical path of sucrose unloading in the sugarcane stalk is described. About 50% of the vascular bundles in the internodes were located within 3 mm of the outside of the stalk. These bundles were inactive in long distance sucrose trans...
In vitro sugar uptake by grapefruit (Citrus paradisi) juice-sac cells [0.03%]

To further our understanding of the mechanisms of sugar uptake and accumulation into grapefruit (Citrus paradisi Macf. cv. Marsh seedless), the patterns of uptake and utilisation of sucrose, glucose and fructose by Citrus juice cells was in...
Components of the Arabidopsis autonomous floral promotion pathway, FCA and FY, are conserved in monocots [0.03%]
拟南芥自主开花途径的组分FCA和FY在单子叶植物中得以保留

Somrutai Winichayakul et al.
The autonomous floral promotion pathway plays a key role in regulating the flowering time of the model dicot Arabidopsis thaliana (L.) Heynh. To investigate whether this pathway is present in monocots, two autonomous pathway components, FCA...
The functional status of paraveinal mesophyll vacuoles changes in response to altered metabolic conditions in soybean leaves [0.03%]

Antibodies raised against tonoplast intrinsic proteins (TIPs) were used to probe the functional status of the soybean [Glycine max (L.) Merr.] paraveinal mesophyll (PVM) vacuole during changes in nitrogen metabolism within the leaf. Young p...
Contribution of initial C and N reserves in Medicago sativa recovering from defoliation: impact of cutting height and residual leaf area [0.03%]
初生长期的叶柄和叶片贮藏物对苜蓿割草后的恢复作用：刈割高度和留叶量的影响分析
