Assessment of genetically modified cotton GHB614 × T304‐40 × GHB119 × COT102 (application EFSA‐GMO‐ES‐2017‐147)

open access: yesEFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Genetically modified cotton GHB614 × T304‐40 × GHB119 × COT102 was developed by crossing to combine four single events: GHB614, T304‐40, GHB119 and COT102. The four‐event‐stack cotton expresses 2mEPSPS, Cry1Ab, Cry2Ae, Vip3Aa19 and PAT/bar to confer herbicide tolerance and insect resistance.

Assessment of genetically modified cotton T304‐40 × GHB119 × COT102 (application EFSA‐GMO‐BE‐2018‐155)

open access: yesEFSA Journal, Volume 23, Issue 12, December 2025.
Abstract Genetically modified cotton T304‐40 × GHB119 × COT102 was developed by crossing to combine three single events: T304‐40, GHB119 and COT102. The three‐event stack cotton expresses Cry1Ab, Cry2Ae, Vip3Aa19 and PAT/bar to confer herbicide tolerance and insect resistance.

The Efficiency Of C-4 Photosynthesis Under Low Light Conditions In Zea Mays, Miscanthus X Giganteus And Flaveria Bidentis

open access: yes, 2013
The efficiency of C4 photosynthesis in Zea mays, Miscanthus x giganteus and Flaveria bidentis in response to light was determined using measurements of gas exchange, 13CO2 photosynthetic discrimination, metabolite pools and spectroscopic assays, with ...

Environmental factors have a greater influence on photosynthetic capacity in C4 plants than biochemical subtypes or growth forms

open access: yesNew Phytologist, Volume 248, Issue 3, Page 1205-1224, November 2025.
Summary Our understanding of how photosynthetic capacity varies among C4 species and across growth and measurement conditions remains limited. We collated 1696 CO2 response curves of net CO2 assimilation rate (A/Ci curves) from C4 species grown and measured at various environmental conditions and used these data to estimate the apparent maximum ...

A guide to understanding and measuring photosynthetic induction: considerations and recommendations

open access: yesNew Phytologist, Volume 247, Issue 2, Page 450-469, July 2025.
Summary Photosynthetic induction is the leaf‐level process by which a plant assimilates CO2 from the atmosphere once exposed to a change in light intensity after a period of darkness or shade. In the field, photosynthetic induction can take place hundreds of times in a single day in response to rapid fluctuations in the light environment due to cloud ...

The role of strigolactone structural diversity in the host specificity and control of Striga, a major constraint to sub‐Saharan agriculture

open access: yesPLANTS, PEOPLE, PLANET, Volume 7, Issue 2, Page 318-330, March 2025.
The parasitic weed Striga affects crops such as sorghum, maize, millet, and rice in over 40 countries on the African continent and negatively impacts the livelihood of over 300 million small‐holder farmers. Striga seeds can remain dormant in the soil for many years until they are triggered to germinate by germination stimulants, called strigolactones ...

The Flaveria bidentis beta-carbonic anhydrase gene family encodes cytosolic and chloroplastic isoforms demonstrating distinct organ-specific expression patterns [PDF]

open access: yes, 2007
Carbonic anhydrase (CA) catalyzes the interconversion of CO(2) and bicarbonate, the forms of inorganic carbon used by the primary carboxylating enzymes of C(3) and C(4) plants, respectively. Multiple forms of CA are found in both photosynthetic subtypes;

Increasing Rubisco as a simple means to enhance photosynthesis and productivity now without lowering nitrogen use efficiency

open access: yesNew Phytologist, Volume 245, Issue 3, Page 951-965, February 2025.
Summary Global demand for food may rise by 60% mid‐century. A central challenge is to meet this need using less land in a changing climate. Nearly all crop carbon is assimilated through Rubisco, which is catalytically slow, reactive with oxygen, and a major component of leaf nitrogen.
