The C(4) plant tissue cultures have one-half to one-third the photorespiration rate of the C(3) plant tissue cultures and respond to varying O(2) concentrations in a manner typical of C(4) plants. J Exp Bot. What is Kranz Anatomy? In these plants, the mesophyll cells cluster around the bundle-sheath cell in a wreath formation (Kranz means ‘wreath or ring). 1976 Oct;58(4):573-5. doi: 10.1104/pp.58.4.573. Rubisco is inherently inefficient because it can also catalyze a reaction with oxygen, giving a wasteful process known as photorespiration (rather … Significance of Kranz Anatomy to Low Photorespiration in C, Developmental Programming of Thermonastic Leaf Movement, BRASSINOSTEROID-SIGNALING KINASE5 Associates with Immune Receptors and Is Required for Immune Responses, Deetiolation Enhances Phototropism by Modulating NON-PHOTOTROPIC HYPOCOTYL3 Phosphorylation Status, by The American Society of Plant Biologists, Photorespiration in C3 and C4 Plant Tissue Cultures, © 1976 American Society of Plant Biologists. Kranz anatomy of the leaves. The parenchyma sheath cells are larger than those of the terrestrial form and contain chloro-plasts (Figures 1C and 1D). In Kranz anatomy, the mesophyll and bundle sheath cells are connected by plasmodesmata or cytoplasmic bridges. 1972 Jun;49(6):1021-3 Kranz anatomy is a specialized structure in C 4 Plants where the mesophyll cells are clustered around the bundle-sheath cells in a ring-like fashion. Plant Physiol. DOI: https://doi.org/10.1104/pp.58.4.573. Abstract. 1972 Mar;149(1):269-80 The results suggest that the lack of detectable photorespiration in C(4) plants is not related to leaf anatomy. Together they form a unique fingerprint.

The primary function of Kranz anatomy is to provide a site in which CO2 can be concentrated … Xu C, Blair LC, Rogers SM, Govindjee, Widholm JM. Photorespiration in c(3) and c(4) plant tissue cultures: significance of kranz anatomy to low photorespiration in c(4) plants. Photorespiration rates in tissue cultures of a C4 plant, Portulaca oleracea , were compared to those in tissue cultures of a C3 plant, Streptanthus tortuosus. The amphibious leafless sedge Eleocharis vivipara develops C4-like traits as well as Kranz anatomy under terrestrial conditions, but it develops C3-like traits without Kranz anatomy under submerged conditions. Voznesenskaya EV, Koteyeva NK, Edwards GE, Ocampo G. J Exp Bot.

C 4 photosynthesis incorporates novel leaf anatomy, metabolic specialisations and modified gene expression. 1988 Dec;88(4):1297-302. doi: 10.1104/pp.88.4.1297. Photosynthetic characteristics of photoautotrophically grown tobacco callus cells. Fingerprint Dive into the research topics of 'The occurrence of C₄ species in the genus Rhynchospora and its significance in kranz anatomy of the cyperaceae'. The high starch content of mesophyll cells suggests they may benefit from an internal source of CO 2, for example via C 4 metabolism, and are also sites of starch storage. The vascular elements in c4 leaves remain surrounded by a layer of bundle sheath cells containing chloroplast in abundance. The chloroplasts in mesophyll cells are granal, whereas in bundle sheath cells they are agranal. When submerged plants are exposed to aerial conditions, they rapidly produce new photosynthetic tissues with C4-like traits. Tomoshiro Takeda, Osamu Ueno, Waichi Agata, The occurrence of C4 species in the genusRhynchospora and its significance in kranz anatomy of the cyperaceae, The Botanical Magazine Tokyo, 10.1007/BF02489486, 93, 1, (55-65), (1980).
