Summary Thermo‐sensitive genic male sterile (TGMS) lines are the core of two‐line hybrid rice (Oryza sativa). However, elevated or unstable critical sterility‐inducing temperatures (CSITs) of TGMS lines are bottlenecks that restrict the development of two‐line hybrid rice. However, the genes and molecular mechanisms controlling CSIT remain unknown. Here, we report the CRITICAL STERILITY‐INDUCING TEMPERATURE 2 (CSIT2) that encodes a really interesting new gene (RING) type E3 ligase, controlling the CSIT of thermo‐sensitive male sterility 5 (tms5)‐based TGMS lines through ribosome‐associated protein quality control (RQC). CSIT2 binds to the large and small ribosomal subunits and ubiquitinates 80S ribosomes for dissociation, and may also ubiquitinate misfolded proteins for degradation. Mutation of CSIT2 inhibits the possible damage to ubiquitin system and protein translation, which allows more proteins such as catalases to accumulate for anther development and inhibits abnormal accumulation of reactive oxygen species (ROS) and premature programmed cell death (PCD) in anthers, partly rescuing male sterility and raised the CSIT of tms5‐based TGMS lines. These findings reveal a mechanism controlling CSIT and provide a strategy for solving the elevated or unstable CSITs of tms5‐based TGMS lines in two‐line hybrid rice.

“…Our CoMPP results do not show any significant differences in the levels of low-DM HG epitopes between the two Crassula growth forms, while the differences in the levels of high-DM HG epitopes are probably just a consequence of different extractability across the extraction steps (Figure 4). The results of the immunolocalization of pectic epitopes show that high-DM HGs are present throughout mesophyll cell walls in Crassula (Figure 7M-T), which is indicative of inherently elastic cell walls (Hongo et al, 2012;Wang et al, 2022). High-DM HGs and higher cell wall elasticity have often been associated with walls of cells that easily change shape, while the opposite is often true for cells that have ceased growth or that display very limited capacity for shape changes (Bárány et al, 2010;Bou Daher et al, 2018;Creff et al, 2023;Dolan et al, 1997;Majewska-Sawka et al, 2002;Siedlecka et al, 2008; but see Palin & Geitmann, 2012;Wang et al, 2020).…”

Cell wall traits are believed to be a key component of the succulent syndrome, an adaptive syndrome to drought, yet the variability of such traits remains largely unknown. In this study, we surveyed the leaf polysaccharide and glycoprotein composition in a wide sampling of Crassula species that occur naturally along an aridity gradient in southern Africa, and we interpreted its adaptive significance in relation to growth form and arid adaptation. To study the glycomic diversity, we sampled leaf material from 56 Crassula taxa and performed comprehensive microarray polymer profiling to obtain the relative content of cell wall polysaccharides and glycoproteins. This analysis was complemented by the determination of monosaccharide composition and immunolocalization in leaf sections using glycan‐targeting antibodies. We found that compact and non‐compact Crassula species occupy distinct phenotypic spaces in terms of leaf glycomics, particularly in regard to rhamnogalacturonan I, its arabinan side chains, and arabinogalactan proteins (AGPs). Moreover, these cell wall components also correlated positively with increasing aridity, which suggests that they are likely advantageous in terms of arid adaptation. These differences point to compact Crassula species having more elastic cell walls with plasticizing properties, which can be interpreted as an adaptation toward increased drought resistance. Furthermore, we report an intracellular pool of AGPs associated with oil bodies and calcium oxalate crystals, which could be a peculiarity of Crassula and could be linked to increased drought resistance. Our results indicate that glycomics may be underlying arid adaptation and drought resistance in succulent plants.

“…The main process represented by these genes includes vesicular transportation, methylation, and pectin biosynthesis related to cell-wall organization. Pectin metabolism has been shown to play a role in heat tolerance in Arabidopsis and rice [ 219 , 220 ]. Drought and salinity partially overlap in their biophysical effect on plant cells by inducing osmotic stress, and both stresses show similar patterns in terms of cytosolic and extracellular responses.…”

The vast majority of agricultural land undergoes abiotic stress that can significantly reduce agricultural yields. Understanding the mechanisms of plant defenses against stresses and putting this knowledge into practice is, therefore, an integral part of sustainable agriculture. In this review, we focus on current findings in plant resistance to four cardinal abiotic stressors—drought, heat, salinity, and low temperatures. Apart from the description of the newly discovered mechanisms of signaling and resistance to abiotic stress, this review also focuses on the importance of primary and secondary metabolites, including carbohydrates, amino acids, phenolics, and phytohormones. A meta-analysis of transcriptomic studies concerning the model plant Arabidopsis demonstrates the long-observed phenomenon that abiotic stressors induce different signals and effects at the level of gene expression, but genes whose regulation is similar under most stressors can still be traced. The analysis further reveals the transcriptional modulation of Golgi-targeted proteins in response to heat stress. Our analysis also highlights several genes that are similarly regulated under all stress conditions. These genes support the central role of phytohormones in the abiotic stress response, and the importance of some of these in plant resistance has not yet been studied. Finally, this review provides information about the response to abiotic stress in major European crop plants—wheat, sugar beet, maize, potatoes, barley, sunflowers, grapes, rapeseed, tomatoes, and apples.
