Project description:Elevated CO2 (eCO2) condition has influence on developing leaf growth of rice (Oryza sativa cv. Nipponbare), specifically lower than P4 (plastochron number) stage, resulting in decrease in leaf size compared with that grown at ambient CO2 (aCO2). In this case, decrease in leaf size seems to be one of acclimation process at CO2 replete environment despite of the fact that number of tiller increase during CO2 replete periods; however, it is not yet elucidated which endogenous signal play a precise role in depression of developing leaf growth in those process. In this context, to elucidate precise signal interaction between mature and developing leaf of rice at eCO2 environment, we profiled gene expressions of mature rice leaf blade (P6) using oligo DNA microarray 4X44K RAP-DB (Agilent Technologies, Santa clara, CA).

Project description:Elevated CO2 (eCO2) has an influence on developing leaf growth of rice (Oryza sativa cv. Nipponbare), specifically lower growth stage than P4 (plastochron number), resulting in decrease in leaf size compared with that in ambient CO2 (aCO2). Since several micro RNAs are associated with the regulation of plant leaf development, in order to clarify which micro RNAs are involved in the decrease of leaf blade size at eCO2, we carried out high-throughput small RNA sequencing analysis and compared the amount of identified miRNAs in developing rice leaf blade grown between aCO2 and eCO2 condition.

Project description:Plant respiration responses to elevated growth [CO2] are key uncertainties in predicting future crop and ecosystem function. In particular, the effects of elevated growth [CO2] on respiration over leaf development are poorly understood. This study tested the prediction that, due to greater whole-plant photoassimilate availability and growth, elevated [CO2] induces transcriptional reprogramming and a stimulation of nighttime respiration in leaf primordia, expanding leaves, and mature leaves of Arabidopsis thaliana. In primordia, elevated [CO2] altered transcript abundance, but not for genes encoding respiratory proteins. In expanding leaves, elevated [CO2] induced greater glucose content and transcript abundance for some respiratory genes, but did not alter respiratory CO2 efflux. In mature leaves, elevated [CO2] led to greater glucose, sucrose and starch content, plus greater transcript abundance for many components of the respiratory pathway, and greater respiratory CO2 efflux. Therefore, growth at elevated [CO2] stimulated dark respiration only after leaves transitioned from carbon sinks into carbon sources. This coincided with greater photoassimilate production by mature leaves under elevated [CO2] and peak respiratory transcriptional responses. It remains to be determined if biochemical and transcriptional responses to elevated [CO2] in primordial and expanding leaves are essential prerequisites for subsequent alterations of respiratory metabolism in mature leaves.

Arabidopsis plants were grown in either ambient (370 ppm) or elevated (750 ppm) CO2. Leaf number 10 was harvested when it was a primordia, expanding, or mature in each of the CO2 treatments.

Project description:Analysis of rice leaves (V2 stage) in response to a short treatment with very high CO2 concentration in the dark, using standard atmosphere as control. Results provide insight into molecular mechanisms occurring in response to these extreme conditions, which are often used in the food industry.

Project description:Analysis of rice leaves (V2 stage) in response to a short treatment with very high CO2 concentration in the dark, using standard atmosphere as control. Results provide insight into molecular mechanisms occurring in response to these extreme conditions, which are often used in the food industry. V2 rice plants were either treated with 30% [CO2] or kept under normal atmosphere (control) for 6 h at 27ºC in the dark. Two biological replicates per treatment (30% [CO2] and control), each encompassing the leaves of ten plants, were analyzed.

Project description:The transcript responses of both growing, trifoliate 6 and fully expanded, trifoliate 4 soybean leaves to elevated CO2 was investigated. We also compared the transcriptome of fully expanded vs. developing leaves in both ambient and elevated CO2. Keywords = soybean Keywords = elevated carbon dioxide Keywords = global change Keywords = leaf growth Keywords = plant Keywords: soybean leaf comparisons
