“…Therefore, nuclear-encoded photosynthesis-associated genes known to be controlled by retrograde signals were included in the set of genes, namely RBCS , LHCB4 , LHCA1 , PSAD , and ELIP58 (Pfannschmidt et al , 2001; Gray et al , 2003; Osipenkova et al , 2010). RBCS encodes the small subunit of Rubisco, and LHCB4, LHCA1, and PSAD are components of the photosystems.…”

“…Taking into consideration that the RNAi-W1-7 plants were not able to accelerate senescence in response to high light, WHIRLY1 might play a role in retrograde signalling which during senescence as well as during chloroplast development was proposed to adjust nuclear gene expression to the functional state of chloroplasts ( Pfannschmidt and Munné-Bosch, 2013 ). Therefore, nuclear-encoded photosynthesis-associated genes known to be controlled by retrograde signals were included in the set of genes, namely RBCS , LHCB4 , LHCA1 , PSAD , and ELIP58 ( Pfannschmidt et al , 2001 ; Gray et al , 2003 ; Osipenkova et al , 2010 ).

“…Nutritional stress established by BA treatment can induce fruit abscission and may transmit signals via ROS, sugar, and hormones signaling crosstalk [31]. In a previous study, carbohydrates played an important role in signal delivery and material communication [63]. The previous study found that carbohydrate may be a biochemical signal controlling fruits abscission [22], and carbon starvation increases flower abscission [23].…”

Chemical defoliation is an important part of cotton mechanical harvesting, which can effectively reduce the impurity content. Thidiazuron (TDZ) is the most used chemical defoliant on cotton. To better clarify the mechanism of TDZ promoting cotton leaf abscission, a greenhouse experiment was conducted on two cotton cultivars (CRI 12 and CRI 49) by using 100 mg L −1 TDZ at the eight-true-leaf stage. Results showed that TDZ significantly promoted the formation of leaf abscission zone and leaf abscission. Although the antioxidant enzyme activities were improved, the reactive oxygen species and malondialdehyde (MDA) contents of TDZ increased significantly compared with CK (water). The photosynthesis system was destroyed as net photosynthesis (Pn), transpiration rate (Tr), and stomatal conductance (Gs) decreased dramatically by TDZ. Furthermore, comparative RNA-seq analysis of the leaves showed that all of the photosynthetic related genes were downregulated and the oxidation-reduction process participated in leaf shedding caused by TDZ. Consequently, a hypothesis involving possible cross-talk between ROS metabolism and photosynthesis jointly regulating cotton leaf abscission is proposed. Our findings not only provide important insights into leaf shedding-associated changes induced by TDZ in cotton, but also highlight the possibility that the ROS and photosynthesis may play a critical role in the organ shedding process in other crops.Previous studies have found that ethylene accelerates organ abscission, while auxin inhibits this process [5][6][7][8][9]. Meanwhile, researchers have paid attention to the fact that multiple cell wall-degrading enzymes are activated to dissolve the cell wall and middle lamella of abscission zone, including cellulases, pecticlyases, polygalactosidases [10][11][12]. Some research has found that hydrogen peroxide (H 2 O 2 ) acts downstream from ethylene and plays a role in the cell-wall degradation process in abscission signaling [13,14].Reactive oxygen species (ROS), including H 2 O 2 , superoxide, singlet oxygen, and the hydroxyl radical, are produced in response to environmental stress [13]. Environmental stresses (such as drought, cold stress, salt stress, and pathogen attack) are often accompanied by leaf abscission [15][16][17], but the relationship between stress and abscission is rarely studied. Excessive ROS can damage cellular components, including lipids, protein, and nucleic acids [18]. ROS produced at the abscission zone site play an important role in regulating leaf abscission under drought stress in cassava (Manihot esculenta Crantz) [19]. Recent studies have found that ROS do not work in the fruit abscission zone of olives (Olea europaea L.), but only alter oxidative stress in the abscission zone of leaves and then mediate abscission induced by ethephon [20]. Previous studies have shown that insufficient carbohydrate accumulation and distribution can lead to flower and fruit abscission. For example, carbohydrate stress can induce longan (Dimocarpus longan Lour.) fruit abscissi...

“…59 No. 1 2012 signals could enhance effects of light signals or con verse them from inducers into repressors of genes for photosynthetic proteins [70][71][72]. It is believed that plastid retrograde signals are endogenous regulators of light signaling and that integration of light and plastid signals help plants to overcome chloroplast dysfunc tion during organelle biogenesis under unfavorable conditions of illumination [71].…”

This review summarizes the current knowledge of the biosynthesis of tetrapyrroles in plants, key stages of this process regulation, as well as the available data on the participation of these compounds in the induction and transmission of retrograde signals. Possible sources of retrograde signals are considered. Par ticular attention is paid to the analysis of data on the signaling molecules that induce retrograde regulation. The interaction of retrograde signals with other cells signaling pathways is emphasized.
