“…The same pattern was observed for FLH and PH ( Figure 1C, D), as the cultivars from private companies, (TBIO Sintonia, TBIO Sossego, TBIO Ponteiro, TBIO Aton, TBIO Duque, and CD 1303) presented higher FLH and PH values in addition to greater DF and greater DN values. Breeding programs should aim to minimize FLH and PH values in selection (Richards et al 2019), especially in the Brazilian Cerrado, because taller genotypes tend to exhibit lodging if the system is irrigated.…”

“…Regulation of stomatal function at the source level has also pointed out some exciting potentials for crop-yield improvement, particularly as stomata offer a promising improvement through water-use efficiency, which is critical to crop-yield improvement. Several other factors improve photosynthetic carbon acquisition and yield at the source level [ 199 , 200 ]. However, whether carbon utilization or limitation in source and sink organs are responsible for crop yields has been a confounding issue over several decades.…”

Photosynthetic carbon converted to sucrose is vital for plant growth. Sucrose acts as a signaling molecule and a primary energy source that coordinates the source and sink development. Alteration in source–sink balance halts the physiological and developmental processes of plants, since plant growth is mostly triggered when the primary assimilates in the source leaf balance with the metabolic needs of the heterotrophic sinks. To measure up with the sink organ’s metabolic needs, the improvement of photosynthetic carbon to synthesis sucrose, its remobilization, and utilization at the sink level becomes imperative. However, environmental cues that influence sucrose balance within these plant organs, limiting positive yield prospects, have also been a rising issue over the past few decades. Thus, this review discusses strategies to improve photosynthetic carbon assimilation, the pathways actively involved in the transport of sucrose from source to sink organs, and their utilization at the sink organ. We further emphasize the impact of various environmental cues on sucrose transport and utilization, and the strategic yield improvement approaches under such conditions.

“…Thus, it will be possible to increase RUE by designing a new wheat ideotype with a ‘smart canopy’ for wheat with erect flag leaves to allow light penetration to lower (and usually shaded) parts of the canopy and to avoid light saturation, similarly to what has been proposed for sorghum canopies ( Mantilla-Perez et al , 2020 ). Evidence found in wheat canopies indicates that erectophile genotypes can have up to 11% higher biomass and 24% higher yields compared with planophile genotypes ( Richards et al , 2019 ); therefore, the addition of erectophile genotypes and the use of remote sensing models that correlate NPQ and PRI can become important in wheat physiological breeding to increase RUE, biomass, and yield, especially because wheat is grown under contrasting light environments across different latitudes, which leaves the door open to further increase the genetic gains of these traits.…”

Wheat yields are stagnating or declining in many regions, requiring efforts to improve the light conversion efficiency, i.e. radiation use efficiency (RUE). RUE is a key trait in plant physiology because it links light capture and primary metabolism with biomass accumulation and yield, but its measurement is time consuming and this has limited its use in fundamental research and large scale physiological breeding. In this study, high-throughput phenotyping (HTPP) approaches were used among a population of field grown wheat with variation in RUE and photosynthetic traits to build predictive models of RUE, biomass and intercepted photosynthetically active radiation (IPAR). Three approaches were used: best combination of sensors, canopy vegetation indices and partial least square regression. The use of remote sensing models predicted RUE with up to 70% accuracy compared to ground truth data. Water indices and NDVI are the better option to predict RUE, biomass and IPAR, and indices related to NPQ (PRI) and senescence (SIPI) are better predictors for these traits at the vegetative and grain filling stages respectively. These models will be instrumental to explain canopy processes, improve crop growth, yield modelling, and potentially be used to predict RUE in different crops or ecosystems.
