Can small reductions in Rubisco content improve nitrogen use in wheat without negatively impacting biomass or grain yield?

This study reduces Rubisco in wheat using RNAi to test if nitrogen use efficiency can improve without affecting biomass or yield, but finds no improvement in nitrogen use efficiency despite similar biomass in some lines.

Simultaneous Overexpression of Three Enzymes of Chloroplast Metabolism Fails to Improve CO2 Assimilation or Biomass.

This study tests overexpressing three chloroplast enzymes in tobacco to boost photosynthesis and biomass but finds no significant improvement under tested conditions.

Extensive photophysiological variation in wild barley is linked to environmental origin

The paper identifies photophysiological variation in wild barley linked to environmental origin through common garden experiments and GWAS.

DNA methylation contributes to plant acclimation to naturally fluctuating light

This study shows that DNA methylation changes in Arabidopsis thaliana under fluctuating light conditions compared to square light, affecting gene expression and transposable elements.

Engineering Rubisco Condensation in Chloroplasts to Manipulate Plant Photosynthesis

This study engineers Rubisco condensation in tobacco chloroplasts using sfGFP fusion to create pyrenoid-like structures, enhancing photosynthetic efficiency without affecting function.

Guard cell photorespiration has a major impact on photosynthesis, growth and stomatal behavior in Arabidopsis

The paper manipulates photorespiration in Arabidopsis guard cells and finds it significantly affects stomatal behavior, growth, and photosynthesis.

Green Conversations: Harnessing Plant Communication to control growth light intensity.

The paper develops a real-time plant bio-feedback system to optimize light intensity, increasing yield and reducing energy use in controlled environment agriculture.
