“…Starch accumulation at full expansion of flag leaves could be attributed to the fact that starch, as the main product of photosynthesis, might not be entirely transported from leaves (resource) to ears (sink) because ears were very small and not fully developed at 0 DAFE. This also indicated that the net photosynthetic rate at full expansion of flag leaves may be higher for LYPJ and its maternal line PA64S than for its paternal line WM9311, which is consistent with data on photosynthetic rates (Zhang et al, 2007). Therefore, altered thylakoid membrane structure may directly affect membrane functionality and could have deleterious effects on photosynthetic activities of chloroplasts (Chen et al, 2004).…”

“…The higher IUFA in PA64s (implying higher fluidity) was accompanied by its higher photosynthetic rate (Zhang et al, 2007) at 0 DAFE, whereas after 28 DAFE, LYPJ and its paternal line WM9311 had higher IUFA with higher photosynthetic rates than PA64S, suggesting that the advantage of higher yield in LYPJ and WM9311 was mainly demonstrated in the late stage of rice plant development.…”

“…Liangyoupeijiu as the plant material, which had large mid-veins. We have elucidated a wealth of photosynthetic traits of leaf laminae in the super hybrid rice (Zhang et al 2007 ). In order to examine whether rice mid-veins had innate properties of C 4 -like photosynthesis, physiological traits, biochemical parameters, and spectral indicators were compared between leaf laminae and mid-veins in O. sativa .…”

BackgroundRecent studies have shown that C4-like photosynthetic pathways partly reside in photosynthetic cells surrounding the vascular system of C3 dicots. However, it is still unclear whether this is the case in C3 monocots, especially at the molecular level.ResultsIn order to fill this gap, we investigated several characteristics required for C4 photosynthesis, including C4 pathway enzymes, cyclic/non-cyclic photophosphorylation rates, the levels and assembly state of photosynthetic machineries, in the mid-veins of C3 monocots rice with leaf laminae used as controls. The signature of photosystem photochemistry was also recorded via non-invasive chlorophyll a fluorescence and reflectance changes at 820 nm in vivo. Our results showed that rice mid-veins were photosynthetically active with higher levels of three C4 decarboxylases. Meanwhile, the linear electron transport chain was blocked in mid-veins due to the selective loss of dysfunctional photosystem II subunits. However, photosystem I was sufficient to support cyclic electron flow in mid-veins, reminiscent of the bundle sheath in C4 plants.ConclusionsThe photosynthetic attributes required for C4 photosynthesis were identified for the first time in the monocotyledon model crop rice, suggesting that this is likely a general innate characteristic of C3 plants which might be preconditioned for the C4 pathway evolution. Understanding these attributes would provide a base for improved strategies for engineering C4 photosynthetic pathways into rice.Electronic supplementary materialThe online version of this article (doi:10.1186/s12284-016-0094-5) contains supplementary material, which is available to authorized users.

“…Cd toxicity also hampers the Calvin cycle and shows inhibitory effects on various enzyme activities ( Ying et al, 2010 ). Enzymes RUBP and PEP play a vital role during photosynthesis and are involved in CO 2 fixation ( Zhang et al, 2007 ). Excessive Cd ions decrease the activity of RUBP and PEP by causing alteration in their structures, and replace essential cofactors, such as Mg 2+ , which are involved in the process of carboxylation and shift to oxygenation reactions ( Tran and Popova, 2013 ).…”

Cadmium (Cd) is a major environmental contaminant due to its widespread industrial use. Cd contamination of soil and water is rather classical but has emerged as a recent problem. Cd toxicity causes a range of damages to plants ranging from germination to yield suppression. Plant physiological functions, i.e., water interactions, essential mineral uptake, and photosynthesis, are also harmed by Cd. Plants have also shown metabolic changes because of Cd exposure either as direct impact on enzymes or other metabolites, or because of its propensity to produce reactive oxygen species, which can induce oxidative stress. In recent years, there has been increased interest in the potential of plants with ability to accumulate or stabilize Cd compounds for bioremediation of Cd pollution. Here, we critically review the chemistry of Cd and its dynamics in soil and the rhizosphere, toxic effects on plant growth, and yield formation. To conserve the environment and resources, chemical/biological remediation processes for Cd and their efficacy have been summarized in this review. Modulation of plant growth regulators such as cytokinins, ethylene, gibberellins, auxins, abscisic acid, polyamines, jasmonic acid, brassinosteroids, and nitric oxide has been highlighted. Development of plant genotypes with restricted Cd uptake and reduced accumulation in edible portions by conventional and marker-assisted breeding are also presented. In this regard, use of molecular techniques including identification of QTLs, CRISPR/Cas9, and functional genomics to enhance the adverse impacts of Cd in plants may be quite helpful. The review’s results should aid in the development of novel and suitable solutions for limiting Cd bioavailability and toxicity, as well as the long-term management of Cd-polluted soils, therefore reducing environmental and human health hazards.
