“…During filling stage, the photosynthetic rates of the flag leaves were measured using a Li-6400 portable photosynthesis system (Li-Cor, Lincoln, NE, USA) under the following conditions: 400 lmol mol À1 ambient CO 2 ; 1200 lmol m À2 sec À1 photosynthetic photon flux density and 500 lmol sec À1 air flow rate. The chlorophyll content was determined by spectrophotometry (Ye et al, 2016). The middle parts of flag leaves were collected from wild-type and mutant plants cut into segments of about 1 cm each.…”

SummaryWater deficit is a major environmental threat affecting crop yields worldwide. In this study, a drought stress‐sensitive mutant drought sensitive 8 (ds8) was identified in rice (Oryza sativa L.). The DS8 gene was cloned using a map‐based approach. Further analysis revealed that DS8 encoded a Nck‐associated protein 1 (NAP1)‐like protein, a component of the SCAR/WAVE complex, which played a vital role in actin filament nucleation activity. The mutant exhibited changes in leaf cuticle development. Functional analysis revealed that the mutation of DS8 increased stomatal density and impaired stomatal closure activity. The distorted actin filaments in the mutant led to a defect in abscisic acid (ABA)‐mediated stomatal closure and increased ABA accumulation. All these resulted in excessive water loss in ds8 leaves. Notably, antisense transgenic lines also exhibited increased drought sensitivity, along with impaired stomatal closure and elevated ABA levels. These findings suggest that DS8 affects drought sensitivity by influencing actin filament activity.

Low‐temperature‐sensitive leaf color mutants are valuable materials for investigating the mechanisms related to chloroplast development and chlorophyll biosynthesis under low‐temperature conditions. PSL1 is a spontaneous low‐temperature‐sensitive purple‐striped leaf mutant of wheat (Triticum aestivum L.). The progeny of PSL1 exhibited three leaf color phenotypes under low‐temperature conditions (i.e., purple and albino leaf [pur], purple‐striped and albino‐striped leaf [pst], and normal green leaf [gre]). The leaf color of pur and pst displayed normal green under high temperature conditions. The leaf color of gre remained normal green under cold or high temperatures. The critical low temperature for leaf color variations in pur and pst was ∼5°C for >35 d. The shapes of chloroplasts in the purple and albino leaf sectors were irregular in pur and pst, where the thylakoid lamellar was undeveloped and no grana formed. The chlorophyll and carotenoid contents of pur and gre were remarkably reduced in the purple and albino periods, but the anthocyanin contents accumulated greatly in the same period. The photosynthetic capacities of the flag leaves in pur, pst, and gre were the same as that in the Xinong1125 during the heading stage. Genetic analysis showed that the leaf color mutations in PSL1 in response to temperature were controlled by cytoplasmic inheritance. Quantitative real‐time polymerase chain reaction showed that the psbA and psbC genes were downregulated most in the newly developed leaf tissues in pur and pst under low temperatures. This indicated that the psbA and psbC genes may be involved in chloroplast development under low‐temperature conditions in wheat.

Leaves are the primary food‐producing organs for a plant that carry out photosynthesis and contribute to biomass and grain yield. Leaf senescence is a developmentally regulated physiological process but early leaf senescence is known to negatively affect plant yield. The cuticle is an outer waxy protective layer on the leaf surface which protects plants from pathogens attack as well as dehydration. Our understanding of the molecular mechanisms underlying cuticle development and leaf senescence is still immature. The present study reports the role of the DEGENERATED PANICLE AND PARTIAL STERILITY 1 (DPS1) gene encoding a cystathionine β‐synthase (CBS) domain‐containing protein in cuticle development and leaf senescence in rice. The dps1 loss‐of‐function mutant showed leaf senescence phenotype with twisted leaves, significantly reduced chlorophyll content and degenerated chloroplasts characterized by a reduced number of starch granules and an abundance of osmiophilic bodies. Furthermore, dps1 leaves displayed defective cuticle development, reduced wax and cutin compounds, and lower relative water content as compared with wild type. Physiological assays showed significantly higher accumulation of reactive oxygen species (ROS) accompanied by enhanced DNA fragmentation in dps1 leaves, which could be associated with chloroplast degeneration and defective cuticle development. Transcriptome analysis revealed altered expression of several critical genes related to photosynthesis and wax/cutin pathway. This study revealed a crucial role of DPS1 in regulating leaf cuticle development and senescence by affecting the expression of several genes. Thus, a moderate expression of DPS1 is necessary for better plant growth and productivity.
