“…Accordingly, the introduction of all these traits into C3 plants that may lack the ability to naturally evolve C4 photosynthesis is considered a challenging task ( Figure 2 A; Denton et al., 2013 , Schuler et al., 2016 , Wang et al., 2016 ). As previously shown in rice and in many other C3 crops, yield is drastically limited by the photosynthetic capacity of leaves and the carbohydrates factories are unable to fill the larger number of florets or fruits of modern plants ( Pearcy and Ehleringer, 1984 , Hibberd et al., 2008 , von Caemmerer and Evans, 2010 , von Caemmerer et al., 2012 , Sowjanya et al., 2019 ). Therefore, the introduction of higher-capacity photosynthetic mechanisms has challenged the scientific community to engineer C4 pathway into rice ( Hibberd et al., 2008 ).…”

Much attention has been given to the enhancement of photosynthesis as a strategy for the optimization of crop productivity. As traditional plant breeding is most likely reaching a plateau, there is a timely need to accelerate improvements in photosynthetic efficiency by means of novel tools and biotechnological solutions. The emerging field of synthetic biology offers the potential for building completely novel pathways in predictable directions and, thus, addresses the global requirements for higher yields expected to occur in the 21st century. Here, we discuss recent advances and current challenges of engineering improved photosynthesis in the era of synthetic biology toward optimized utilization of solar energy and carbon sources to optimize the production of food, fiber, and fuel.

“…Light is an essential factor for the growth of G.versteegii seedlings and trees through photosynthesis [9]. The assimilation process is carried out by the seedlings using the light that enters the forest floor [10]. The intensity of light entering the forest floor is greatly influenced by the density and type of canopy above it [11].…”

Due to the depletion of its natural population, the Gyrinops versteegii species, one of the species producing agarwood, has been domesticated in Indonesia, particularly in Sragen Central Java. As a result, it was designated as a vulnerable species in both CITES Appendix II and the IUCN Red List Ver23. The research objective is to determine the effect of the light intensity on the number of seedlings, tree density, height, and diameter of the G.versteegii tree growth. The study was conducted from February to October 2018 at a domesticated agarwood community forest in Sragen, Central Java. A systematic plot method, a random start, was applied to this research with 28 nested plots, 1x1 m2 for seedlings and 10x10 m2 for the trees. The data were analyzed using both hierarchical clustering and correlation analysis. The relative light intensity of 2,82% led to an enormous number of seedlings and tree diameter, while the relative light intensity of 0.31% resulted in the highest tree density. The number of seedlings and tree diameter was strongly correlated with the relative light intensity. In contrast, there is an inverse relationship between tree density and relative light intensity.

“…The world needs an introduction of a new "Green revolution" in agriculture to increase crop production for food security and biofuel, because conventional breeding method have not brought much of gains not keeping its pace with the world population growth (Sowjanya et al, 2019). The future is threatened by the after-effects of COVID-19 in agriculture, impacts of climate change, increasing population and the burning issue of food security.…”

Rice (Oryza sativa L.) has been cultivated as an important cereal crop for more than 9,000 years and more than half of the world’s population depend on rice as it is their primary source of energy. Almost 30% of the current world cereal production is represented by the rice alone. It is estimated that the world’s population will reach 9.1 billion by 2050 i.e. 34 percent higher than today and for ensuring an ample amount of food and nutrition to such large population, global consumption of cereals will need to increase from 2.6 to 2.9 billion tonnes by 2027. On the other hand, the impacts of climate change in agriculture are expected to be negative, threatening the global food security. Besides, agriculture and global food security will be severely affected due to the COVID-19 pandemics as its after-effects are yet to be ascertained. The world needs an introduction of a new “Green revolution” in agriculture to increase crop production for food security and biofuel, because conventional breeding method have not brought much of gains not keeping its pace with the world population growth. Hence, the current study was done to review the various ongoing approaches and possible ways of designing a rice with enhanced productivity and photosynthetic capacity. One of the ways to increase yields, photosynthetic capacity accompanied by an increased Water Use Efficiency (WUE) and Nutrient Use Efficiency could be to introduce C4 traits into rice. Besides, genetic engineering using CRISPR-Cas9, molecular breeding, developing ideotype, heterosis breeding, developing apomictic rice, nitrogen fixing rice, use of nanotechnology as well as precision farming are the probable future approaches for designing a rice with high productivity. However, there are challenges and limitations in developing such rice and further research in this matter could help us get closer to developing the future rice.
