“…Among them, yellowing of leaves is an important type of mutation. In general, yellow leaf mutants occur due to the decrease in leaf Chl content (Ou et al 2008, Zhang et al 2017, accompanied by destruction of leaf thylakoid structure (Chen et al 2008, Wang et al 2013, reduction of the net photosynthetic rate and plant growth potential (Zhu et al 2014a, Zhang et al 2017, Yang et al 2018. The mutations causing a typical yellow Chl-less mutant phenotype has also the effects on ratio between two photosystems (Terao andKatoh 1996, Brestič et al 2015), which influences the photoprotective capacity of the mutants and tolerance to stress conditions (Georgieva et al 2003, Brestič et al 2016, Živčák et al 2019.…”

Tree peony is a famous ornamental plant in the world. However, little is known about the leaf color mutants in tree peony. The present study monitored the physiological and photosynthetic properties of a yellow leaf mutant (yl1) in tree peony. The results showed that the yl1 mutant had lower pigment contents, but increased chlorophyll (Chl) a/b and carotenoids to Chl ratio. Microstructure and ultrastructure analysis showed that the yl1 mutant had smaller chloroplasts, few thylakoid stacks, and a few stroma thylakoid membranes remained along with clusters of osmiophilic granules, which might result from inhibition at the reactions from coproporphyrinogen III to protoporphyrin IX. The yl1 mutant had lower leaf net photosynthetic rate, stomatal conductance, transpiration rate, and stomata limitation value, but higher intercellular CO2 concentration. Analysis of simple sequence repeat markers indicated that four pairs of primers could obtain different bands in the genome of the yl1 mutant compared to the wild type.

“…Rice is a C 3 plant; therefore, the C 3 pathway is considered as the main photosynthetic pathway, still the C 4 pathway also operates to varying extents under certain conditions (Ou et al 2008). Rubisco activity is positively correlated with carboxylation efficiency (Farquhar andSharkey 1982, Collatz 1977).…”

To address the issue of water eutrophication and to use water more effectively, we conducted experiments on rice (Oryza sativa L.) grown in floating culture. From 2009 to 2011, we compared the photosynthesis and root characteristics of the rice, hybrid line Zhuliangyou 02, grown under a conventional tillage and in a floating culture in Huaihua, the home of hybrid rice. Rice in the floating culture showed a higher net photosynthetic rate and stomatal conductance than that under the conventional tillage. The activities of phosphoenolpyruvate carboxylase and NADP-malic enzyme were 32 and 28% higher, respectively, in rice in the floating culture than under the conventional tillage. Rice in the floating culture also showed significantly greater number of roots, root activity, and antioxidant enzyme activity than that under the conventional tillage. Compared with rice under the conventional tillage, rice in the floating culture had 18 and 24% higher tiller number and effective panicle number, respectively. These results suggested that the floating culture system can promote rice production through enhancing root absorption, increasing effective panicle number, and improving the photosynthetic rate. In addition, rice cultivated in the floating culture could remove excess nutrients from water, which addresses the problems of a lack of arable land and water pollution.

Abstract. To investigate the phenotypic variation of cucumber photosynthesis, net photosynthetic efficiency of cucumbers were measured by LI-6400XT Portable Photosynthesis System. Non-rectangular hyperbolic model was adopted to fit the light response curve. We used 16 cucumber accessions selected from the core collection that consists of over 400 accessions. As a result, cucumbers show a moderate variance in the phenotype of light compensation point (LCP), light saturation point (LSP) and apparent quantum efficiency (AQY), dark respiration rate (R d ), and maximum net photosynthetic rate (A max ). In a detail, the coefficient of variation (CV) of LCP and R d is 48.97% and 48.09%, respectively, which is relatively high. In contrast, the CV values of A max , LSP and AQY are all smaller than 25%. These results help us get better understanding about the phenotypic variation of photosynthesis in cucumber germplasm.
