Modifying plant photosynthesis and growth via simultaneous chloroplast transformation of Rubisco large and small subunits
<p>Engineering improved Rubisco poses a crucial strategy for enhancing photosynthesis but is challenged by the alternate locations of the plastome rbcL gene and nuclear RbcS genes. Here we develop a RNAi-RbcS Nicotiana tabacum (tobacco) master-line, tobRrΔS, amenable to rbcL-rbcS co-engineering by chloroplast transformation. Four tobacco genotypes coding alternative rbcS genes and adjoining 5ˈ-intergenic sequences revealed Rubisco production was highest in the lines incorporating a rbcS gene whose codon use and 5ˈUTR matched rbcL. These lines produced up to 50% the wild-type Rubisco content. Additional tobacco lines coding potato rbcL-rbcS operons examined how the differing mesophyll made small subunits (pS1, pS2, pS3) or the trichome pST-25 subunit influenced Rubisco biogenesis, catalysis, leaf physiology and plant growth. Rubisco levels were ~15% lower in leaves expressing pS3 relative to those producing pS1, pS2, and pST. However, the pS3-subunit increased carboxylation rate (kcatC) by 13% and carboxylation efficiency (CE, kcatC divided by the Km for CO2) by 17% relative to the pS1 and pS2 subunits as a result of the βa-βb loop substitutions Asn-55-His and Lys-57-Ser. By contrast tobacco photosynthesis and growth were most impaired in lines producing the pST-subunit that reduced CE and CO2/O2 specificity of potato Rubisco by 40% and 15% respectively.<br> </p>
Data from: Herbivore-induced volatiles induce increases in net photosynthesis and reduce plant susceptibility to oviposition in wild and cultivated plants
<p><span>Despite the growing body of studies demonstrating that herbivore-induced plant volatiles (HIPV) induce and prime receiver plant defences, few studies have investigated the effect of HIPVs on primary metabolism of receiver plants and whether responses to HIPVs are consistent across wild and cultivated plant varieties. </span>Here we investigated the effect of HIPVs on net photosynthesis, stomatal conductance,<span> volatile emissions, and </span>number of eggs laid by female <i>Plutella xylostella </i>on receiver plants in two wild and two cultivated <i>Brassica rapa</i> varieties. <span>Plants responded to exposure to HIPVs by increasing their </span>net <span>photosynthesis and stomatal conductance. Responses were clearest in two varieties i.e., Cordelia and a wild </span>Moroccan population, <span>for which </span>exposure to HIPVs also reduced their susceptibility to oviposition but did not alter volatile emissions. The results constitute an advance to research on plant-plant interactions by showing that exposure to HIPVs can promote plant primary metabolism by increasing photosynthesis as a probable <span>mechanism to compensate for costs of induced defences</span>. The results also suggest that responses to HIPVs is <span>maintained across wild and cultivated plants but varies among varieties, and that the </span>traits responsible for effective plant-plant interaction might not have been affected by breeding<span>.</span></p>
JAMES technical report, scripts and data for "'Comparison of C3 photosynthetic responses to light and CO2 predicted by the leaf photosynthesis models of Farquhar et al. (1980) and Goudriaan et al. (1985)"
<p>Dear reader,</p> <p>In this repository you will find 7 MATLAB scripts and 3 Excel datasets. The script "A_curves_Figure2.m" calls the function scripts "FvCB_model_Figure2.m", "FvCB_model_Figure2_noTPU" and "G85_model_Figure2" to create Figure 2 of the JAMES publication. The script "G85_Rd_FigureS1" calls the function script "G85_model_FigureS1" to create Figure S1 of the Supporting Information. The script "r2_RMSE_Table2" calculates statistics displayed in Table 2 of the JAMES publication. The Excel worksheet "Table2.xlsx" contains the values in Table 2 of the JAMES publication for quick data copying. The Excel worksheets "FvCBparameters_fitted_withTPU.xlsx" and "FvCBparameters_fitted_noTPU.xlsx" contains fitted FvCB model parameter values that were obtained using the "fitaci" function from the plantecophys R package (Duursma, 2015). <br> <br> Kind regards,</p> <p>Kevin van Diepen </p>
