“…Moreover, there might be a difference in SL production in monocots and dicots under drought, which could be confirmed in future by comparing SL levels in the monocots and dicots under the same experimental setup. On the other hand, the transcript levels of the SL‐biosynthetic genes D27 and MAX1 ‐homologues Os01g0701400 , Os01g0700900 , Os02g0221900 , and Os06g0565100 were upregulated in rice shoots, as was observed for SlCCD7 and SlCCD8 in the case of tomato (Haider et al, ; Visentin et al, ). These data were in agreement with the detection of increased transcript levels of SL‐biosynthetic genes MAX3 and MAX4 in the leaves of Arabidopsis upon dehydration (C. V. Ha et al, ) and NaCl and mannitol treatments (Lv et al, ), as well as with the upregulation of the SL‐biosynthetic FaD17 gene in the crowns of tall fescue ( Festuca arundinacea ) and the D10 , D17 , and D27 genes in the base of rice stems under drought stress (Table ; Du et al, ; Zhuang et al, ).…”

“…The data obtained from the studies of SL‐deficient mutants clearly indicate a role for SLs in ABA‐mediated stomatal operation, thereby regulating osmotic pressure during plant adaptation to water deficit (Figure ; C. V. Ha et al, ; Liu et al, ; Visentin et al, ). Intriguingly, a recent study in rice reported that the d17/ccd7 mutant plants showed higher ABA accumulation in shoots under drought; however, the authors did neither examine the ABA‐mediated stomatal closure nor the ABA responsiveness of the d17 mutant (Haider et al, ), which would allow us to make a valuable comparison with what was observed in dicot plants, such as Arabidopsis , L. japonicus , and tomato. It is worth mentioning that treatment of broad bean ( Vicia faba ) with GR24 enhanced stomatal closure in a concentration‐dependent manner (Y. Zhang et al, ).…”

“…Similarly, Visentin et al () reported that the transcript abundance of SL‐biosynthetic genes SlCCD7 and SlCCD8 and SL levels were decreased in tomato roots under drought. In contrast, an increase in the levels of SLs was observed in rice roots in response to a water withholding‐induced drought (Haider et al, ). The discrepancy in SL production in roots might be ascribed to the different methods of drought treatment and the different levels of drought imposed.…”

Phytohormones play central roles in boosting plant tolerance to environmental stresses, which negatively affect plant productivity and threaten future food security. Strigolactones (SLs), a class of carotenoid-derived phytohormones, were initially discovered as an "ecological signal" for parasitic seed germination and establishment of symbiotic relationship between plants and beneficial microbes. Subsequent characterizations have described their functional roles in various developmental processes, including root development, shoot branching, reproductive development, and leaf senescence. SLs have recently drawn much attention due to their essential roles in the regulation of various physiological and molecular processes during the adaptation of plants to abiotic stresses. Reports suggest that the production of SLs in plants is strictly regulated and dependent on the type of stresses that plants confront at various stages of development. Recently, evidence for crosstalk between SLs and other phytohormones, such as abscisic acid, in responses to abiotic stresses suggests that SLs actively participate within regulatory networks of plant stress adaptation that are governed by phytohormones. Moreover, the prospective roles of SLs in the management of plant growth and development under adverse environmental conditions have been suggested. In this review, we provide a comprehensive discussion pertaining to SL-mediated plant responses and adaptation to abiotic stresses.

“…Under drought, ABA will be produced in the shoot (Borghi et al 2015) or transported from the root to the shoot (Ko and Helariutta 2017), inducing stomatal closure. Haider et al (2018) found a significant increase in leaf ABA content of rice plants under drought. IAA is important for root and shoot development, and it has been reported that IAA can induce the establishment of arbuscular mycorrhizal fungi (AMF) (Lüdwig-Müller and Güther 2007;Fitze et al 2005).…”

Increased arbuscular mycorrhizal fungal colonization reduces yield loss of rice (Oryza sativa L.) under drought

Drought reduces the availability of soil water and the mobility of nutrients, thereby limiting the growth and productivity of rice. Under drought, arbuscular mycorrhizal fungi (AMF) increase P uptake and sustain rice growth. However, we lack knowledge of how the AMF symbiosis contributes to drought tolerance of rice. In the greenhouse, we investigated mechanisms of AMF symbiosis that confer drought tolerance, such as enhanced nutrient uptake, stomatal conductance, chlorophyll fluorescence, and hormonal balance (abscisic acid (ABA) and indole acetic acid (IAA)). Two greenhouse pot experiments comprised three factors in a full factorial design with two AMF treatments (low-and high-AMF colonization), two water treatments (well-watered and drought), and three rice varieties. Soil water potential was maintained at 0 kPa in the well-watered treatment. In the drought treatment, we reduced soil water potential to − 40 kPa in experiment 1 (Expt 1) and to − 80 kPa in experiment 2 (Expt 2). Drought reduced shoot and root dry biomass and grain yield of rice in both experiments. The reduction of grain yield was less with higher AMF colonization. Plants with higher AMF colonization showed higher leaf P concentrations than plants with lower colonization in Expt 1, but not in Expt 2. Plants with higher AMF colonization exhibited higher stomatal conductance and chlorophyll fluorescence than plants with lower colonization, especially under drought. Drought increased the levels of ABA and IAA, and AMF colonization also resulted in higher levels of IAA. The results suggest both nutrient-driven and plant hormone-driven pathways through which AMF confer drought tolerance to rice.

overexpression transgenic plants showed shorter growth period, 2 6 short-narrow flag leaves, and thick-green leaves. Transcript profile, abscisic acid 2 7 (ABA) and gibberellin acid (GA 3 ) level, and culm composition also changed 2 8 obviously. Abstract 3 0 OsSPL14, identified as IDEAL PLANT ARCHITECTURE1 (IPA1) or WEALTHY 3 1 FARMER'S PANICLE (WFP) gene, plays a critical role in regulating rice plant 3 2architecture. Here, the study showed that OsSPL14-overexpression transgenic rice 3 3 plants had shorter growth period, short-narrow flag leaves, and thick-green leaves. 3 4 Compared with wild type plant 'MH86', transgenic plants had higher chlorophyll a 3 5 (Ca), chlorophyll b (Cb) and carotenoid (Cx) content at both seedling and maturity 3 6 stage. Meanwhile, transcriptome analysis identified 473 up-regulated and 103 3 7 down-regulated genes in transgenic plant. The expression of differentially expressed 3 8 genes (DEGs) involved in carotenoid biosynthesis, abscisic acid (ABA) metabolism 3 9 and lignin biosynthesis increased significantly. Most of DEGs participated in "plant 4 0 hormone signal transduction" and "starch and sucrose metabolism" are also 4 1 up-regulated in transgenic plant. In addition, there were higher levels of ABA and 4 2 gibberellin acid (GA 3 ) in OsSPL14-overexpression transgenic plants. Moreover, the 4 3 content of culm lignin, cellulose, silicon and potassium all increased dramatically. 4 4 Thus, these results demonstrate that overexpression of OsSPL14 has influence on leaf 4 5 development, hormone level and culm composition in rice, which provide more 4 6 insight into understanding the function of OsSPL14. 4 7 4 8
