Abstract
Aldehyde dehydrogenase (ALDH), a common oxidoreductase in organisms, is an aldehyde scavenger involved in various metabolic processes. However, its function in different pathogenic fungi remains unknown. Fusarium graminearum causes Fusarium head blight in cereals, which reduces grain yield and quality and is an important global food security problem. To elucidate the pathogenic mechanism of F. graminearum, seven genes encoding ALDH were knocked out and then studied for their function. Single deletions of seven ALDH genes caused a decrease in spore production and weakened the pathogenicity. Furthermore, these deletions altered susceptibility to various abiotic stresses. FGSG_04194 is associated with a number of functions, including mycelial growth and development, stress sensitivity, pathogenicity, toxin production, and energy metabolism. FGSG_00139 and FGSG_11482 are involved in sporulation, pathogenicity, and SDH activity, while the other five genes are multifunctional. Notably, we found that FGSG_04194 has an inhibitory impact on ALDH activity, whereas FGSG_00979 has a positive impact. RNA sequencing and subcellular location analysis revealed that FGSG_04194 is responsible for biological process regulation, including glucose and lipid metabolism. Our results suggest that ALDH contributes to growth, stress responses, pathogenicity, deoxynivalenol synthesis, and mitochondrial energy metabolism in F. graminearum. Finally, ALDH presents a potential target and theoretical basis for fungicide development.

Abstract
Aldehyde dehydrogenase (ALDH) superfamily, comprising enzymes dependent on NAD+ or NADP+, plays an important role in controlling plant growth and development, as well as in responsing to phytohormone and environmental stress. These enzymes possess the ability to prevent toxic effects of aldehydes by converting them into their corresponding carboxylic acids. However, the potential function of ALDH genes in moso bamboo (Phyllostachys edulis) remains largely unknown. In this study, the ALDH gene superfamily in moso bamboo was analyzed through genome-wide screening, the evolutionary relationship of expansion genes was conducted. Tissue-specific expression patterns of ALDH genes were observed in 26 different tissues. Plant hormone and environmental stress responsive cis-elements were identified in the promoter of ALDH genes, which were supported by public databases data on the expression patterns under various abiotic stresses and hormone treatments. ALDH activity was increased in moso bamboo seedlings exposed to drought, compared to control condition. Furthermore, PeALDH2B2 was found to physically interact with PeGPB1 in response to drought. Overall, the study provides a comprehensive analysis of the ALDH family in moso bamboo and contributes to our understanding of the function of ALDH genes in growth, development, and adaptation to drought stresses.

Abstract
The tapetum is the innermost layer of the four layers of the rice anther that provides protection and essential nutrients to pollen grain development and delivers precursors for pollen exine formation. The tapetum has a key role in the normal development of pollen grains and tapetal programmed cell death (PCD) that is linked with sporopollenin biosynthesis and transport. Recently, many genes have been identified that are involved in tapetum formation in rice and Arabidopsis. Genetic mutation in PCD-associated genes could affect normal tapetal PCD, which finally leads to aborted pollen grains and male sterility in rice. In this review, we discuss the most recent research on rice tapetum development, including genomic, transcriptomic and proteomic studies. Furthermore, tapetal PCD, sporopollenin biosynthesis, ROS activity for tapetum function and its role in male reproductive development are discussed in detail. This will improve our understanding of the role of the tapetum in male fertility using rice as a model system, and provide information that can be applied in rice hybridization and that of other major crops.

Abstract
In this study, changes in membrane fatty acid (FA) composition and damage indices contents as well as the transcript patterns of carbonyl-detoxifying genes were evaluated in two chickpea (Cicer arietinum L.) genotypes, cold-tolerant Sel96th11439 and cold-sensitive ILC533 under cold stress (CS; 4 °C). During CS, H2O2 and malondialdehyde (MDA) contents increased (by 47% and 57%, respectively) in the sensitive genotype, while these contents remained unchanged in the tolerant genotype. In tolerant plants, higher content of linoleic, linolenic, unsaturated FAs (UFAs), total FAs and double bond index (DBI) (by 23, 21, 19, 17 and 9%, respectively) was observed at 6 days after stress (DAS) compared to sensitive plants, which, along with alterations of the damage indices, indicate their enhanced tolerance to CS. Compared with the sensitive genotype, less lipoxygenase (LOX) activity (by 59%) in the tolerant genotype was accompanied by decreased MDA and increased levels of UFAs and DBI during CS, particularly at 6 DAS. Upregulation of aldehyde dehydrogenase and aldo-keto reductase genes (by 9- and 10-fold, respectively) at 1 DAS, along with the enhanced transcript levels of aldehyde reductase and 2-alkenal reductase (by 3- and 14.7-fold, respectively) at 6 DAS were accompanied by increased UFAs and reduced MDA contents in the tolerant genotype. Overall, the results suggest that cold tolerance in chickpea was partly associated with regulation of membrane FA compositions and the potential metabolic networks involved in synthesis and degradation of carbonyl compounds.

Comparative genomic analysis of the aldehyde dehydrogenase gene superfamily in Arabidopsis thaliana - searching for the functional key to hypoxia tolerance. FRONTIERS IN PLANT SCIENCE 2022; 13:1000024.

Abstract
Flooding entails different stressful conditions leading to low oxygen availability for respiration and as a result plants experience hypoxia. Stress imposed by hypoxia affects cellular metabolism, including the formation of toxic metabolites that dramatically reduce crop productivity. Aldehyde dehydrogenases (ALDHs) are a group of enzymes participating in various aspects of plant growth, development and stress responses. Although we have knowledge concerning the multiple functionalities of ALDHs in tolerance to various stresses, the engagement of ALDH in plant metabolism adjustment to hypoxia is poorly recognized. Therefore, we explored the ALDH gene superfamily in the model plant Arabidopsis thaliana. Genome-wide analyses revealed that 16 AtALDH genes are organized into ten families and distributed irregularly across Arabidopsis 5 chromosomes. According to evolutionary relationship studies from different plant species, the ALDH gene superfamily is highly conserved. AtALDH2 and ALDH3 are the most numerous families in plants, while ALDH18 was found to be the most distantly related. The analysis of cis-acting elements in promoters of AtALDHs indicated that AtALDHs participate in responses to light, phytohormones and abiotic stresses. Expression profile analysis derived from qRT-PCR showed the AtALDH2B7, AtALDH3H1 and AtALDH5F1 genes as the most responsive to hypoxia stress. In addition, the expression of AtALDH18B1, AtALDH18B2, AtALDH2B4, and AtALDH10A8 was highly altered during the post-hypoxia-reoxygenation phase. Taken together, we provide comprehensive functional information on the ALDH gene superfamily in Arabidopsis during hypoxia stress and highlight ALDHs as a functional element of hypoxic systemic responses. These findings might help develop a framework for application in the genetic improvement of crop plants.

Abstract
Regulated or programmed cell death (RCD or PCD) is a fundamental biological principle integral to a considerable variety of functions in multicellular organisms. In plants, different PCD processes are part of biotic and abiotic stress responses, but also occur as an essential aspect of unperturbed plant development. PCD is particularly abundant during plant reproduction, eliminating unwanted or no longer needed cells, tissues, or organs in a precisely controlled manner. Failure in reproductive PCD can have detrimental consequences for plant reproduction. Here we shed a light on the latest research into PCD mechanisms in plant reproduction from sex determination over sporogenesis to pollination and fertilization.

Abstract
Aldehyde dehydrogenases (ALDHs) act as "aldehyde scavengers" in plants, eliminating reactive aldehydes and hence performing a crucial part in response to stress. ALDH has been specified multiple activities since its identification in the mammalian system 72 years ago. But the most widely researched role in plants is their engagement in stress tolerance. Multiple ALDH families are found in both animals and plants, and many genes are substantially conserved within these two evolutionary diverse taxa, yet both have their unique members/families. A total of twenty-four ALDH protein family has been reported across organisms, where plants contain fourteen families. Surprisingly, the number of genes in the ALDH superfamily has risen in the higher plants because of genome duplication and expansion, indicating the functional versatilely. Observed expansion in the ALDH isoforms might provide high plasticity in their actions to achieve diversified roles in the plant. The physiological importance and functional diversity of ALDHs including plant development and environmental stress adaptability, and their evolution in plants has been studied extensively. Future investigations need to focus on evaluating the individual and interconnecting function of multiple ALDH isoforms across organisms in providing plants with proper development, maturation, and adaptability against harsh environmental conditions.

Abstract
Newly synthetic autotetraploid rice shows lower pollen fertility and seed setting rate relative to diploid rice, which hinders its domestication and breeding. In this study, cytological analysis showed that at meiosis I stage, an unbalanced segregation of homologous chromosomes, occurred as well as an early degeneration of tapetal cells in autotetraploid rice. We identified 941 differentially expressed proteins (DEPs) in anthers (meiosis I), including 489 upregulated and 452 downregulated proteins. The DEPs identified were related to post-translational modifications such as protein ubiquitination. These modifications are related to chromatin remodeling and homologous recombination abnormalities during meiosis. In addition, proteins related to the pentose phosphate pathway (BGIOSGA016558, BGIOSGA022166, and BGIOSGA028743) were downregulated. This may be related to the failure of autotetraploid rice to provide the energy needed for cell development after polyploidization, which then ultimately leads to the early degradation of the tapetum. Moreover, we also found that proteins (BGIOSGA017346 and BGIOSGA027368) related to glutenin degradation were upregulated, indicating that a large loss of glutenin cannot provide nutrition for the development of tapetum, resulting in early degradation of tapetum. Taken together, these evidences may help to understand the differences in anther development between diploid and autotetraploid rice during meiosis.

Abstract
In plants, lipid transfer proteins (LTPs) transport pollen wall constituents from the tapetum to the exine, a process essential for pollen wall development. However, the functional cooperation of different LTPs in pollen wall development is not well understood. In this study, we have identified and characterized a grass-specific LTP gene, OsLTP47, an important regulator of pollen wall formation in rice (Oryza sativa). OsLTP47 encodes a membrane-localized LTP and in vitro lipid-binding assays confirms that OsLTP47 has lipid-binding activity. Dysfunction of OsLTP47 causes disordered lipid metabolism and defective pollen walls, leading to male sterility. Yeast two-hybrid and pull-down assays reveal that OsLTP47 physically interacts with another LTP, OsC6. These findings suggest that the plasma membrane-localized OsLTP47 may function as a mediator in a lipid transfer relay through association with cytosolic and/or locular OsC6 for pollen wall development and that various LTPs may function in a coordinated manner to transport lipid molecules during pollen wall development.

Abstract
A candidate gene for male fertility restoration in Brassica juncea, BjRf, was isolated from a 23-kb interval on chromosome A05 using map-based cloning and BSA methods. The cytoplasmic male sterility/fertility restoration (CMS/Rf) system has been extensively used for heterosis in plants. It also provides valuable resources for studying mitochondrial-nuclear coevolution and interaction. The oxa CMS, which is a new CMS type reported in Brassica juncea (B. juncea), has been broadly used in the exploitation and application of heterosis in this species. However, the oxa CMS fertility restorer gene BjRf has not been reported. In this study, a stable restorer line was successfully constructed via continuous testcross and artificial selection. Besides, a new Rf gene was mapped in a 23-kb region on chromosome A05 in B. juncea with a genetic distance of 0.5 cM by the method incorporating bulk segregant analysis (BSA) and conventional map-based cloning. Finally, BjuA017917, a non-PPR Rf gene encoding a guanosine nucleotide diphosphate dissociation inhibitor (GDI), is proposed to be the candidate gene for fertility restoration of the oxa CMS line in B. juncea. Moreover, a functional marker, CRY3, was developed for marker-assisted selection for Brassica juncea breeding.

Abstract
Developmental programmed cell death (dPCD) has multiple functions in plant growth and development, and is of great value for industrial production. Among them, wood formed by xylem dPCD is one of the most widely used natural materials. Therefore, it is crucial to explore the molecular mechanism of plant dPCD. The dPCD process is tightly regulated by genetic networks and is involved in the transduction of signaling molecules. Several key regulators have been identified in diverse organisms and individual PCD events. However, complex molecular networks controlling plant dPCD remain highly elusive, and the original triggers of this process are still unknown. This review summarizes the recent progress on the transcriptional regulation and signaling of dPCD during vegetative and reproductive development. It is hoped that this review will provide an overall view of the molecular regulation of dPCD in different developmental processes in plants and identify specific mechanisms for regulating these dPCD events. In addition, the application of plants in industrial production can be improved by manipulating dPCD in specific processes, such as xylogenesis.

Abstract
Developmentally programmed cell death (dPCD) is a tightly controlled biological process. In recent years, vital roles of dPCD on regulating floral organ growth and development have been reported. It is well known that flower is an essential organ for reproduction and a turning point of plants' life cycle. Hence, uncovering the complex molecular networks which regulates dPCD processes in floral organs is utmost important. So far, our understanding of dPCD on floral organ growth and development is just starting. Herein, we summarize the important factors that involved in the tapetal degeneration, pollen tube rupture, receptive synergid cell death, nucellar degradation, and antipodal cell degradation. Meanwhile, the known factors that involved in transmitting tract formation and self-incompatibility-induced PCD were also introduced. Furthermore, the genes that associated with anther dehiscence and petal senescence and abscission were reviewed as well. The functions of various types of factors involved in floral dPCD processes are highlighted principally. The regulatory panorama described here can provide us some insights about flower-specific dPCD process.

Abstract
Abiotic and biotic stresses induce the formation of reactive oxygen species (ROS), which subsequently causes the excessive accumulation of aldehydes in cells. Stress-derived aldehydes are commonly designated as reactive electrophile species (RES) as a result of the presence of an electrophilic α, β-unsaturated carbonyl group. Aldehyde dehydrogenases (ALDHs) are NAD(P)+-dependent enzymes that metabolize a wide range of endogenous and exogenous aliphatic and aromatic aldehyde molecules by oxidizing them to their corresponding carboxylic acids. The ALDH enzymes are found in nearly all organisms, and plants contain fourteen ALDH protein families. In this review, we performed a critical analysis of the research reports over the last decade on plant ALDHs. Newly discovered roles for these enzymes in metabolism, signaling and development have been highlighted and discussed. We concluded with suggestions for future investigations to exploit the potential of these enzymes in biotechnology and to improve our current knowledge about these enzymes in gene signaling and plant development.

PLANT SCIENCE : AN INTERNATIONAL JOURNAL OF EXPERIMENTAL PLANT BIOLOGY 2020; 299:110581. [PMID: 32900435 DOI: 10.1016/j.plantsci.2020.110581] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/18/2020] [Revised: 06/03/2020] [Accepted: 06/23/2020] [Indexed: 05/28/2023]
Abstract
Peiai 64S (PA64S) is a photoperiod- and thermo sensitive genic male sterile (PTGMS) rice line that has been widely applied in two-line hybrid rice breeding. The male fertility mechanism of PTGMS has always been the research focus. We obtained fertile PA64S (F) and sterile fertile PA64S (S) plants at 21℃ and 28℃, respectively. Here, we analyzed the development of anthers and pollen grains of PA64S (S) and found that the degradation of tapetum and sporopollenin accumulation of pollen exine was abnormal. The content of lipid components in PA64S (F) and PA64S (S) were different by LC-MS, among which sterols, (O-acyl) ω-hydroxy fatty acids, ceramide, and other lipid components were upregulated in PA64S (F). The results of transcriptome showed that many significantly different genes were enriched in the lipid metabolism pathways. Additionally, lipid synthesis and transport genes were downregulated in PA64S (S). In summary, the differences of the PA64S fertility under different temperatures were analyzed through multi-levels comparison. These results suggest that lipid synthesis and transport during PA64S anther development affects the lipid accumulation of pollen exine, and ultimately affected fertility. The differences in lipids content may also be a factor affecting PA64S pollen fertility.
