“…Increasing CO 2 diffusion from the atmosphere to the leaf interior increases A (Lawson et al , ) and it has been demonstrated in several studies that manipulating stomatal density (Tanaka et al , ) or aperture (Lawson and Blatt, ; Duan et al , ) increases g s, while recent studies have also suggested that stomatal kinetics and the rapidity of g s responses to the changing environment can increase carbon assimilation (McAusland et al , ; Papanatsiou et al , ). Increasing g s represents a trait already unintentionally included in breeding for high yielding varieties over many decades (Fischer et al , ; Lu et al , ; De Vita et al , ).…”

Raising crop yield potential is a major goal to ensure food security for the growing global population. Photosynthesis is the primary determinant of crop productivity and any gain in photosynthetic CO 2 assimilation per unit of leaf area (A) has the potential to increase yield. Significant intraspecific variation in A is known to exist in various autotrophic organs that represent an unexploited target for crop improvement. However, the large number of factors that influence photosynthetic rates often makes it difficult to measure or estimate A under dynamic field conditions (i.e. fluctuating light intensities or temperatures). This complexity often results in photosynthetic capacity, rather than realized photosynthetic rates being used to assess natural variation in photosynthesis. Here we review the work on natural variation in A, the different factors determining A and their interaction in yield formation. A series of drawbacks and perspectives are presented for the most common analyses generally used to estimate A. The different yield components and their determination based on different photosynthetic organs are discussed with a major focus on potential exploitation of various traits for crop improvement. To conclude, an example of different possibilities to increase yield in wheat through enhancing A is illustrated. -Greenhouse conditions Ouyang et al. (2017) Rice 0.15-0.31 0.05-0.21 Pot experiment

“…Hydrogen sulfide H 2 S has dual effects on plant growth and development. A high concentration of H 2 S can cause cytotoxicity, while a low concentration of H 2 S does not cause toxicity to plants and may act as a signaling molecule (Duan et al, 2015;Li et al, 2016). Recently, many studies have found that H 2 S can regulate plant growth and development, such as inducing plant seed germination (Liu and Lal, 2015), improving photosynthetic capacity (Coyne and Bingham, 1978;Chen et al, 2011), regulating stomatal movement (Lisjak et al, 2011;Scuffi et al, 2014), promoting the development of lateral roots (Jia et al, 2015;, regulating secondary metabolism of sugar, polyamines, organic acids and amino acids (Shi et al, 2015;Chen et al, 2016), participating in protein modification (Mustafa et al, 2009), maintaining ion balance in plants (Wang et al, 2012;Lai et al, 2014), delaying ripening and senescence of postharvest fruits during storage (Fu et al, 2014;Hu et al, 2014), and improving antioxidant capacity (Luo et al, 2015).…”

In this study, we investigated the mechanism of photosynthesis and physiological function of blueberry leaves under low temperature stress (4-6°C) by exogenous hydrogen sulfide (H 2 S) by spraying leaves with 0.5 mmol·L -1 NaHS (H 2 S donor) and 200 mmol·L -1 hypotaurine (Hypotaurine, H 2 S scavenger). The results showed that chlorophyll and carotenoid content in blueberry leaves decreased under low temperature stress, and the photochemical activities of photosystem II (PSII) and photosystem I (PSI) were also inhibited. Low temperature stress can reduce photosynthetic carbon assimilation capacity by inhibiting stomatal conductance (G s ) of blueberry leaves, and non-stomatal factors also play a limiting role at the 5 th day of low temperature stress. Low temperature stress leads to the accumulation of Pro and H 2 O 2 in blueberry leaves and increases membrane peroxidation. Spraying leaves with NaHS, a donor of exogenous H 2 S, could alleviate the degradation of chlorophyll and carotenoids in blueberry leaves caused by low temperature and reduce the photoinhibition of PSII and PSI. The main reason for the enhancement of photochemical activity of PSII was that exogenous H 2 S promoted the electron transfer from Q A to Q B on PSII acceptor side under low temperature stress. In addition, it promoted the accumulation of osmotic regulator proline under low temperature stress and significantly alleviated membrane peroxidation. H 2 S scavengers (Hypotaurine) aggravated photoinhibition and the degree of oxidative damage under low temperature stress. Improving photosynthetic capacity as well as alleviating photosynthetic inhibition and oxidative stress with exogenous H 2 S is possible in blueberry seedlings under low temperature stress.

“…Parveen et al (2017) showed that low concentration of NaHS improved the photosynthesis and the growth of submerged macrophytes. Duan et al (2015) showed that suitable concentration of NaHS improved PN and Chl contents of rice seedlings. In this study, our findings showed that NaHS also improved PN and Chl content in Arabidopsis.…”

We investigated the role of nitric oxide (NO) in the regulation of ascorbate-glutathione (AsA-GSH) cycle and water physiological characteristics of Arabidopsis thaliana by sodium hydrosulfide (NaHS). NaHS markedly increased the contents of H2S, NO, chlorophyll (Chl), and carotenoids, the activity of AsA-GSH cycle, ascorbate/dehydroascorbate ratio, net photosynthetic rate, Chl fluorescence parameters, transpiration rate, stomatal conductance, and relative water content in leaves and the biomass of wild-type Arabidopsis. However, NaHS markedly decreased malondialdehyde content and electrolytic leakage. Except H2S, above NaHS-induced promotions were suppressed by nitrate reductase (NR) inhibitor sodium azide (NaN3). Application of sodium nitroprusside (SNP) to (NaN3+NaHS)-treated wild type Arabidopsis (NaN3+SNP+NaHS) reversed above effects of NaN3+NaHS. However, NaN3+NaHS and NaN3+SNP+NaHS had no significant effects on H2S content. Meanwhile, we proved above results by using NO-associated NR gene mutant nia1,nia2. Above results suggested that NO participated in the regulation of AsA-GSH cycle and water physiological characteristics of Arabidopsis by NaHS.
