Effect of stomatal morphology on leaf photosynthetic induction under fluctuating light across diploid and tetraploid rice

MYC2 regulates stomatal density and water use efficiency via targeting EPF2/EPFL4/EPFL9 in poplar

“…Through RNA-sequencing and reverse transcription quantitative polymerase chain reaction Transcriptional regulation mechanism of decreased stomatal density in plant polyploid leaves Numerous studies have shown that polyploid leaves have larger stomata and a significantly lower stomatal density (Hetherington & Woodward, 2003;Oliveira et al, 2004;Padoan et al, 2013;Monda et al, 2016). For example, the stomatal density of tetraploid Arabidopsis and rice is significantly lower than that of diploid plants (Monda et al, 2016;Xiong et al, 2022). The stomatal density of tetraploid poplar, eucalyptus, and triploid eucalyptus was also significantly lower than that of diploids (Lu et al, 2014;Yang et al, 2018;Ren et al, 2021;Liu et al, 2022).…”

Photosynthetic response dynamics in the invasive species Tithonia diversifolia and two co-occurring native shrub species under fluctuating light conditions

“…The integrated amount of CO 2 uptake ( C indu ) during 30 min of light induction, and the integrated amount of CO 2 uptake ( C relax ) during 15 min of light relaxation were calculated using Eq. (1) : where A t is the transient photosynthetic rate ( Xiong et al., 2022 ).…”

Effects of Environmental and Non-Environmental Factors on Dynamic Photosynthetic Carbon Assimilation in Leaves under Changing Light

“…Soleh et al also reported the activation rate of Rubisco was related to the single-nucleotide polymorphisms of the Rubisco activase gene [ 79 ]. In contrast, research on Oryza sativa [ 85 ], Musa nana [ 81 ] and Manihot esculenta [ 82 ] showed that stomatal conductance was the major limitation to dynamic photosynthesis under changing light conditions. Adachi et al reported that the faster induction response to sudden increases in light intensity in a high-yield Oryza sativa cultivar (Takanari), compared with a cultivar with lower yield (Koshihikari), was explained in part by the maintenance of a larger pool of Calvin–Benson cycle metabolites in Takanari [ 73 ].…”

“…However, recent research showed that pre-dawn stomatal opening does not substantially enhance photosynthetic induction in Helianthus annuus [ 89 ]. It has also been reported that smaller and denser stomata contributed to a faster stomatal response under changing light, resulting in improved photosynthetic induction [ 85 , 90 , 91 ]. The stomatal closure rate also affects dynamic photosynthesis under changing light conditions.…”
