“…Moreover, a significant increase in the lignification in the monocotyledonous species reduces salts and other toxic solute movement into the stele [96]. On the other hand, a decreased deposition of lignin increases salt sensitivity to rice [31]. Changes in the lignin content as a response to biotic and abiotic stress was also previously reported in the date palm [97][98][99][100].…”

Salinity is a global agricultural problem, resulting in a significant reduction in the plantation areas and the crop yields, especially in arid and semiarid regions. The date palm is relatively salt-tolerant plant species, although the nature of salt tolerance is poorly understood. In this study, the salt stress responses of a salt-tolerant “Umsila” was compared with salt-susceptible “Zabad” date palm cultivars. Various physiological parameters, plant-water relations, and anatomical characteristics were analyzed. The results revealed that although salinity has negatively affected both cultivars, Umsila exhibited more stable photosynthesis than Zabad as reflected by the quantum yield (Qy) and the stomatal conductance (GS). Similarly, Umsila showed a more dynamic root system and efficient water relations than Zabad as demonstrated by the leaf water potential (LWP) and relative water content (RWC) during salinity. Umsila also accumulated greater abundances of soluble sugars, potassium (K+), calcium (Ca+2), proline, glycine betaine, and lignin and formed extra layers of Casparian strips in the root tissues when the seedlings were grown under saline conditions. Together, the results obtained from this study have offered some insights into the salt tolerance mechanisms in the date palm.

“…Lignin is a complex aromatic phenylpropanoid polymer and is a significant component of the secondary cell wall [31,32]. In general, endodermis tissue is composed of the Casparian strip which consists of a ring of lignin deposited around the endodermal cells and acts as a barrier for water and solute repellants [33,34].…”

“…Jasmonate (JA) is another important phytohormone (Hakata et al ., ; Ishiga et al ., ; Toda et al ., ,b), which regulates diverse aspects of plant developmental and environmental responses, including stamen development, root growth, anthocyanin accumulation, trichome initiation and plant defense against pathogens and insects (Franceschi & Grimes, ; Staswick et al ., ; McConn & Browse, ; Sanders et al ., ; Stintzi & Browse, ; Wasternack, ; Howe & Jander, ; Kazan & Manners, ; Browse, ; Cheng et al ., ; Chung & Howe, ; Shan et al ., , ; Pauwels et al ., ). In recent decades, studies in Arabidopsis have revealed a JA signaling framework.…”

JAZ proteins modulate seed germination through interaction with ABI5 in bread wheat and Arabidopsis

Summary Appropriate regulation of crop seed germination is of significance for agriculture production. In this study, we show that TaJAZ1, most closely related to Arabidopsis JAZ3, negatively modulates abscisic acid (ABA)‐inhibited seed germination and ABA‐responsive gene expression in bread wheat. Biochemical interaction assays demonstrate that the C‐terminal part containing the Jas domain of TaJAZ1 physically interacts with TaABI5. Similarly, Arabidopsis jasmonate‐ZIM domain (JAZ) proteins also negatively modulate ABA responses. Further we find that a subset of JAZ proteins could interact with ABI5 using the luciferase complementation imaging assays. Choosing JAZ3 as a representative, we demonstrate that JAZ3 interacts with ABI5 in vivo and represses the transcriptional activation activity of ABI5. ABA application could abolish the enrichment of JAZ proteins in the ABA‐responsive gene promoter. Furthermore, we find that ABA application could induce the expression of jasmonate (JA) biosynthetic genes and then increase the JA concentrations partially dependent on the function of ABI5, consequently leading to the degradation of JAZ proteins. This study sheds new light on the crosstalk between JA and ABA in modulating seed germination in bread wheat and Arabidopsis.

“…Salt stress can also indirectly and broadly affect the physicochemical properties of plant cell walls by altering the expression of cell wall biosynthesis genes and/or the functional modification of cell wall enzyme activity, and hence, the composition of cell wall components. For instance, salt stress severely decreased the amount of cellulose in the roots of rice ( Oryza sativa ) and cotton ( Gossypium hirsutum ) plants [ 13 , 14 ], and altered the structural arrangement of the majority of the cellulose microfibril network (91% of the investigated cells) in sorghum ( Sorghum bicolor ) longitudinal cell walls, forming a close-meshed network instead of a parallel array [ 15 ].…”

Arabidopsis thaliana (Arabidopsis) has been used extensively as a heterologous system for molecular manipulation to genetically characterize both dicotyledonous and monocotyledonous plant species. Here, we report on Arabidopsis transformant lines molecularly manipulated to over-accumulate the small regulatory RNA microRNA397 (miR397) from the emerging C4 monocotyledonous grass model species Setaria viridis (S. viridis). The generated transformant lines, termed SvMIR397 plants, displayed a range of developmental phenotypes that ranged from a mild, wild-type-like phenotype, to a severe, full dwarfism phenotype. Reverse transcriptase quantitative polymerase chain reaction (RT-qPCR)-based profiling of the SvMIR397 transformant population revealed a strong correlation between the degree of miR397 over-accumulation, repressed LACCASE (LAC) target gene expression, reduced lignin content, and the severity of the developmental phenotype displayed by SvMIR397 transformants. Further, exposure of SvMIR397 transformants to a 7-day regime of salt stress revealed the SvMIR397 transformant lines to be more sensitive to the imposed stress than were wild-type Arabidopsis plants. Taken together, the findings reported here via the use of Arabidopsis as a heterologous system show that the S. viridis miR397 small regulatory RNA is able to repress the expression of three Arabidopsis LAC genes which led to reduced lignin content and increased salt stress sensitivity.
