“…REC was evaluated by the method of Johal et al (2020). Leaf samples (0.1 g) were washed with distilled water and then placed in tubes with 10 ml of distilled water, kept at room temperature for 24 h. The initial electrical conductivity (C1) was measured with a conductivity meter (DDS-11A, Yoke Instrument, China).…”

In order to explore the adaptive strategies of tree peony yl1 mutant in response to photooxidative stress, the changes of biochemical parameters, chlorophyll fluorescence, and the modulated 820-nm reflection of yl1 mutant and wildtype plants were compared. We found the activities of superoxide dismutase and catalase, the contents of soluble protein, proline, superoxide radicals, hydrogen peroxide, malondialdehyde, and relative electrical conductivity were significantly higher than those of the wild type. The photochemical efficiency of PSII significantly decreased, while the proportion of heat dissipation of yl1 mutant increased greatly. The donor and acceptor side and electron transfer of PSII were greatly inhibited. Meanwhile, the performance of PSI and coordination of two photosystems decreased markedly in yl1 mutant. The yl1 mutant could reduce the damage caused by photooxidative stress by increasing the activity of antioxidant enzymes, the content of some osmoregulatory substances, and the proportion of heat dissipation.studying the mechanism of photosynthesis, the structure and function of the photosystems, and Chl biosynthesis, and are valuable for cultivating excellent varieties and molecular marker-assisted breeding (Zhang et al. 2020). Leaf-color mutants with yellow leaves, variegated leaves, stripes, and other characteristics have a high ornamental value in landscaping. Among them, a yellow-leaf mutant is a common mutation type. The paulownia (Paulownia fortnnei) mutant with white flowers presented light green leaves at the seedling stage, they turned yellow at the mature stage, and had a certain ornamental value (Ru et al. Highlights• Higher photooxidative damage was reported in tree peony yl1 mutant compared to the wild type. • The function and coordination of two photosystems in yl1 mutant decreased significantly. • The yl1 mutant increased the contents of antioxidants and osmoregulants and heat dissipation capacity in response to photooxidative stress.

“…Therefore, to obtain a comprehensive understanding of the cellular dehydration tolerance mechanisms of chickpea, which is essential for developing WD-tolerant chickpea varieties to assure sustainable chickpea production under WD conditions, chickpea responses to gradual progressive WD and RD should be both individually investigated. In most published studies, physiological, biochemical, and molecular responses have been investigated in chickpea plants subjected to progressive WD by gradually withholding irrigation or application of polyethylene glycol (Gupta et al 2020a(Gupta et al , 2020bJohal et al 2020;Kalefeto glu Macar & Ekmekçi 2009;Pouresmael et al 2015;Vessal et al 2020). However, to our knowledge, none of the studies has investigated biochemical and physiological parameters of chickpea genotypes during RD conditions.…”

In nature, plants may suffer rapid dehydration (RD), which causes significant loss of the annual global chickpea production. Thus, ascertaining more knowledge concerning the RD-tolerance mechanisms in chickpea is crucial for developing high drought-tolerant varieties to assure sustainable chickpea production under sudden water deficit. Here, we focused on genotype-driven variation in leaf relative water content (RWC) and associated differences in RD-responsive physiological and biochemical attributes in roots and leaves of two chickpea varieties, FLIP00-21C and FLIP02-89C, subjected to well-watered and RD conditions. FLIP00-21C showed higher RD-tolerance than FLIP02-89C, evident by its higher leaf RWC during RD. Consistently, FLIP00-21C exhibited lower membrane injury due to lower hydrogen peroxide (H 2 O 2 ) accumulation than FLIP02-89C during RD, indicating reduced RD-induced oxidative damage. Under RD conditions, total phenolics in roots and flavonoids in roots and leaves increased more in FLIP02-89C compared to FLIP00-21C; however, the increased activities of superoxide dismutase and H 2 O 2 -scavenging enzymes were more properly coordinated in FLIP00-21C than in FLIP02-89C, which might contribute to more efficient antioxidant defense in FLIP00-21C than in FLIP02-89C. The higher leaf RWC of FLIP00-21C versus FLIP02-89C under RD might be associated with greater increases in the levels of the osmo-regulators proline and total free amino acids (TFAAs) in FLIP00-21C than in FLIP02-89C. Collectively, the higher RD-tolerance of FLIP00-21C is mainly associated with the maintenance of higher RWC, stronger antioxidant defense, and greater accumulation of proline and TFAAs. These traits could be useful for evaluating the drought-tolerance of chickpea varieties and further marker-assisted breeding approaches for improvement of chickpea productivity.
