Activity in Sun and Shade Plants1
The consequences of light adaptation and acclimation of photosynthesis on photosynthetic nitrogen use efficiency (NUE), particularly as it relates to the efficiency of ribulose-1,5-bisphosphate carboxylase (Rubisco) use in photosynthetic CO2 assimilation, was studied in the sun species Glycine max and the shade species Alocasia macrorrhiza. Both G. max and A. macrorrhiza were found to possess t...
متن کاملStomatal Biology of CAM Plants1[CC-BY]
Crassulacean acid metabolism (CAM) is a major physiological syndrome that has evolved independently in numerous land plant lineages. CAM plants are of great ecological significance, and there is increasing interest for their water-use efficiency and drought resistance. Integral to the improvement in water-use efficiency that CAM affords is a unique pattern of stomatal conductance, distinguished...
متن کاملEvolution of Gene Duplication in Plants1[OPEN]
Ancient duplication events and a high rate of retention of extant pairs of duplicate genes have contributed to an abundance of duplicate genes in plant genomes. These duplicates have contributed to the evolution of novel functions, such as the production of floral structures, induction of disease resistance, and adaptation to stress. Additionally, recent whole-genome duplications that have occu...
متن کاملCycle with Intact Leaves and Isolated Chloroplasts of C3 Plants1
Mass spectrometric techniques were used to trace the incorporation of 1180loxygen Into metabolites of the photorespiratory pathway. Glycolate, glycine, and serine extracted from leaves ofthe C3 plants, Spinacis okraces L., Atripex hastata, and Helianthus annuus which had been exposed to 1Oloxygen at the C02 compensation point were heavily labeled with 180. In each case one, and only one of the ...
متن کاملClimbing Strategy for a Flexible Tree Climbing Robot - Treebot
In this paper, we propose an autonomous tree climbing strategy for a novel tree climbing robot that is named Treebot. The proposed algorithm aims to guide Treebot in climbing along an optimal path by the use of minimal sensing resources. Inspired by inchworms, the algorithm reconstructs the shape of a tree simply by the use of tactile sensors. It reveals how the realization of an environment ca...
