Various genetic engineering routes to enhance C3 leaf photosynthesis have been proposed to improve crop productivity. However, their potential contribution to crop productivity needs to be assessed under realistic field conditions. Using 31 year weather data, we ran the crop model GECROS for rice in tropical, subtropical, and temperate environments, to evaluate the following routes: (1) improvi...

Recently, three Chenopodiaceae species, Bienertia cycloptera, Bienertia sinuspersici, and Suaeda aralocaspica, were shown to possess novel C(4) photosynthesis mechanisms through the compartmentalization of organelles and photosynthetic enzymes into two distinct regions within a single chlorenchyma cell. Bienertia has peripheral and central compartments, whereas S. aralocaspica has distal and pr...

C(4) photosynthesis has a number of distinct properties that enable the capture of CO(2) and its concentration in the vicinity of Rubisco, so as to reduce the oxygenase activity of Rubisco, and hence the rate of photorespiration. The aim of this review is to discuss the properties of this CO(2)-concentrating mechanism, and thus to indicate the minimum requirements of any genetically-engineered ...

In a recent report identifying the promoters of the Rhodobacter capsulatus glnBA operon, it was suggested that an internal promoter upstream of the glnA gene probably resulted in different levels of glnBA and glnA transcripts (D. Foster-Hartnett and R. G. Kranz, J. Bacteriol. 176:5171-5176, 1994). Therefore, to investigate the regulation, we constructed and examined the expression of a number o...

Fenlong-ridging (FL) is a new type of conservation tillage. In many crops, FL increases crop yield and quality; however, the cytology molecular mechanisms crops under not completely understood. This study investigated soil physical chemical properties conventional tillage (CK) during 2018–2019 (plant cane) 2019–2022 (first stubble), analyzed agronomic trait, physiology, leaf anatomical structur...
