“…Mutants insensitive to ET are hypersensitive to ABA and present extended dormancy periods, while those showing increased ET production exhibit reduced sensitivity to ABA and a decrease in dormancy duration. Furthermore, ET promotes radicle protrusion, germination and seedling establishment by affecting and interacting with GA biosynthesis and signaling pathways [12].…”

Plants make decisions throughout their lifetime based on complex networks. Phase transitions during seed growth are not an exception. From embryo development through seedling growth, several molecular pathways control genome stability, environmental signal transduction and the transcriptional landscape. Particularly, epigenetic modifications and small non-coding RNAs (sRNAs) have been extensively studied as significant handlers of these processes in plants. Here, we review key epigenetic (histone modifications and methylation patterns) and sRNA-mediated regulatory networks involved in the progression from seed maturation to germination, their relationship with seed traits and crosstalk with environmental inputs.

“…Brassinosteroids (BRs) are an important class of plant steroid-based phytohormone that plays multiple roles in regulating plant growth, development, and responses to environmental stresses [7,8,50,51,[61][62][63][64]. 28-homobrassinolide (HBL) and 24-epibrassinolide (EBL) are the two isomers of BRs which regulate an array of plant physiological processes [65,66].…”

“…The signal perception of ET takes place at the membrane of endoplasmic reticulum and is bacterial two-component type which initiates a cascade signaling events through transcriptional regulation in the nucleus, thus eventually controlling a myriad of plant developmental events. Meanwhile, the interplay of ET with other signaling molecules provides adaptation to plants under various abiotic pressures [7,8,[82][83][84][85][86][87][88]. Now, we will focus our attention on various reports on the functions of ET on tolerance toward major abiotic stresses in crop plants.…”

“…Myriads of anthropogenic emissions in the developmental era have further intensified the abiotic stress-induced negative impacts on agricultural productivity. The major abiotic stresses such as metals/metalloids (hereafter termed as "metal/s"), salt, ozone, UV-B radiation, temperature extremes, nutrient (deficiency and excess), flooding, and water deficit are jeopardizing the agriculture system worldwide [7][8][9][10][11][12][13][14][15][16][17][18][19]. These abiotic stresses can modulate almost all plant physiological, biochemical, and molecular processes starting from the seedling to maturity stage and can ultimately cause severe negative impacts on economic yield of various crop plants.…”

Abiotic Stress in Plants

Crop plants are encountered by various abiotic pressures which limit their growth and development. Stresses such as drought, heat, pathogen attack, heavy metal, salinity, and radiations impose negative effect on crop plants. The reduction in crop productivity in the current era of climate change is compromising the efforts/strategies used for sustainable agricultural practices. Therefore, plant stress physiologists are engineering plants with suitable exogenous signaling elicitors to engineer tolerance to various stresses. In the present chapter, an appraisal has been made in the "Introduction" section to first assess the damages caused by various abiotic stresses in crop plants. In the second section, we attempt to summarize the role of various plant hormones, namely, salicylic acid (SA), brassinosteroids (BRs), ethylene (ET), and methyl jasmonate (MJ) in enhancing abiotic stress tolerance. The current concept may lead to the development of strategies for unraveling the underlying mechanisms of plant hormone-mediated abiotic stress tolerance in crop plants.

“…Light-activated photoreceptors inhibit the COP1-SUPPRESSOR OF PHYA-105 (SPA) E3 ubiquitin ligase complex, which functions for the degradation of the positive regulators of photomorphogenesis [7,8]. Notably, HY5, a target of COP1-mediated protein degradation, plays a vital role in light-regulated plant growth and development [9,10]. Thus, the light-dependent regulation of COP1-HY5 mediates the plant developmental transition from dark to light.…”

Background: Perceiving incoming environmental information is critical for optimizing plant growth and development. Multiple B-box proteins (BBXs) play essential roles in light-dependent developmental processes in plants. However, whether BBXs function as a signal integrator between light and temperature in tomato plants remains elusive.Results: In this study, 31 SlBBX genes were identified from the newly released tomato (Solanum lycopersicum) genome sequences, and were clustered into five subgroups with phylogenetic analysis. Gene structure and protein motif analyses showed relatively high conservation of closely clustered SlBBX genes within each subgroup; however, genome mapping analysis indicated the uneven distribution of the SlBBX genes on tomato chromosomes. Synteny analysis indicated that segmental duplication events happened in the expansion of the SlBBX genes in tomato. Promoter cis-regulatory elements prediction indicated that SlBBX genes were highly responsive to light, hormones, and stress conditions. Furthermore, the transcript analysis revealed that various SlBBX genes differed significantly in expression after exposure to different light quality and low temperatures, while 61.3% of SlBBX genes were responsive to both light and low temperatures. Conclusions: Our study presented a genome-wide survey of SlBBX gene family in tomato, and emphasized their functions in perceiving light quality and low temperature, which may improve the current understanding of SlBBX gene functions in integrating light and temperature signals for plant adaptation to adverse environments.
