Here, we show that seeds have mechanisms to survive cold climate prevalent in alpine ecosystems and have identified three such mechanisms from existing literature, including two forms of freezing avoidance (the presence of water impermeable seed coats, and the supercooling of seed tissues) and one form of freezing tolerance (by extracellular-freezing). Experimentally-derived published data on the lowest temperature recorded at which 50% of a seed sample survived (i.e., lethal temperature; LT50) was used to generate a dataset of 24 species across low altitude, boreal and alpine environments. We assumed that the ability of seeds to maintain viability at very low temperatures would increase in species associated with higher altitudes conferring a competitive advantage that would be lost under projected climate change. However, our results reveal to underpin that seeds from boreal species survive relatively better at lower temperatures than those of alpine species. Paradoxically, a warming climate could lead to alpine seed death due to extremes of cold at the soil surface resulting from snow cover loss, whilst the declining snow cover may facilitate boreal forest colonization above the current treeline.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"479 - 492"},"PeriodicalIF":6.9,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1848277","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42854742","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding of the genetic and molecular basis of ovule development is essential from both the scientific and economic perspective. The ovule represents an attractive system to study lateral organ development in plants, and, since ovules are the precursors of seeds, full comprehension of this process can be the key to the improvement of crops, especially those depending on high production of seeds and grains. Ovule initiation, patterning, and morphogenesis are governed by complex genetic and hormonal networks involving auxins, cytokinins, brassinosteroids, and gibberellins. These coordinate the determination of the ovule number, size, and shape through the regulation of the number of ovule primordia that arise from the placenta and/or ensuring their correct development into mature functional ovules. Here we summarize the current knowledge of how ovules are formed, paying special attention to the roles of these four plant hormones.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"431 - 456"},"PeriodicalIF":6.9,"publicationDate":"2020-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1820203","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49289939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under external stimuli, MTFs are released from various membranes, convert into the active form, and are transported into the nucleus for transcriptional regulation. Therefore, unlike most TFs, MTFs go through the unique process of transitioning from the membrane to intracellular regions. There are two typical mechanisms during this period: proteolytic processing and alternative splicing. However, other activation schemes have also recently emerged. To further understand these mechanisms, it is essential to study how MTFs transport within the cell and into the nucleus. Imaging techniques with high spatiotemporal resolution can partially resolve this process but new methods are required for future studies. In this review, we give an overview of the current knowledge of plant MTFs, including their identification, specific localization, and the difficulties in studying their cellular dynamics. We also discuss molecular mechanisms of MTF release and advanced methods, such as fluorescence correlation spectroscopy, single-particle tracking, and photoactivated localization microscopy, to further reveal their intracellular movement in living cells.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"418 - 430"},"PeriodicalIF":6.9,"publicationDate":"2020-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1813922","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47277653","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The loss of function of these genes primarily interrupts the growth and development of invading pathogens and thus makes plants resistant. The S-gene-targeted resistance may produce durable immunity in plants. Because, S gene-based resistance is derived from the inactivation of a host factor required for the survival of a pathogen in the host. To bypass the S gene-based resistance, a parasitic pathogen must evolve and develop the same or similar functions provided naturally by its host factors, which is far more difficult or even may be impossible. However, it is critical to identify and target the appropriate S gene(s) aiming to gain resistant capacity against a particular disease, because S genes may be pathogen-specific in many cases. The clustered regularly interspaced short palindromic repeats (CRISPR) technology has shown great potential in manipulating S genes in plants. The CRISPR-TSKO (CRISPR-based tissue-specific knock-out) tool kit can provide an understanding of the exact function of an individual gene in a tissue and developmental stage-specific manner while also producing a heritable mutant allele. In this review, candidate S genes have been summarized for CRISPR-TSKO mediated tissue-specific gene knockdown to enhance host resistance.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"387 - 417"},"PeriodicalIF":6.9,"publicationDate":"2020-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1810970","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42179787","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil pollution causes Cd contamination of crops, thereby rendering plant products responsible for the chronic low level Cd over-exposure of numerous populations in the world. For this reason, Cd accumulation in plants has been studied for about five decades now. The research first focused on the relationships between plant and soil Cd levels, on the factors of the metal availability in soil, as well as the root uptake processes. Cd distribution in plant organs was also investigated, first using a macroscopic and eco-physiological approach, and then with the help of molecular biology tools, at both tissue and cell scales. Cadmium has no biological function and hijacks the transport pathways of micronutrients such as Fe, Mn, or Zn, in order to enter the plant through the roots and be distributed to all its organs. The study of the genes that control the influx and efflux of the Cd2+ ion in the cytosol, vacuoles, and vascular tissues has significantly contributed to the understanding of the metal root uptake and of its transfer to the aerial parts. However, the mechanisms responsible for its distribution to the different above-ground tissues and specially to fruits and seeds have yet to be clarified. This review summarizes current knowledge in order to present a detailed overview of Cd transport and storage, from the rhizosphere to the different organs and tissues of the plant.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"322 - 359"},"PeriodicalIF":6.9,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1792179","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43084692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bacterial blight (BB) is a very common, widespread, and highly destructive disease of rice. By the introduction of nitrogen-responsive high-yielding rice varieties, there was many-fold increase in the productivity level of tropical rice in recent years. Continuous cropping of rice with high nitrogen use and general wet conditions aggravated the disease incidence. The cost of chemical control measures is high and often shows adverse effects on the environment. Development of host-plant resistance is therefore a preferred approach to control the disease. Evolution of pathogen differentiation in the Xanthomonas oryzae pv. oryzae (Xoo) isolates often causes the breakdown of resistance against the disease. Efforts to deploy R-genes combinations are more important for managing the disease. Durable and broad-spectrum resistance may be achieved in host plants by precise gene incorporation through gene-pyramiding approach. To date, 45 genes conferring resistance to this disease have been identified in rice. The gene-for-gene concept of resistance governs the race-specific interaction between the host and the Xoo strains. Plants have developed different intrinsic mechanisms to defend the pathogen invasion. The pathogen also evolves to produce effectors with variation to counter the patterns-triggered immunity and convert the host plants response for effector-triggered susceptibility. This review discusses the progress in the identification of resistance genes, mechanisms of resistance, and deployment of resistance genes for durable and stable resistance in rice.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"360 - 385"},"PeriodicalIF":6.9,"publicationDate":"2020-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1801559","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47678957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we review recent developments in our understanding of brown algal evolution based on modern advances in phylogenetics and functional genomics. We begin by summarizing modern phylogenetic hypotheses, illuminating the timescales over which the various brown algal orders diversified. We then discuss key insights on our understanding of brown algal life cycle variation and sexual reproduction systems derived from modern genomic techniques.

However, oilseed production is negatively impacted by unpredictable environmental conditions caused by climate change, as well as associated increases in disease and pest infestations. Unfortunately, while conventional breeding techniques have been used to provide gains in terms of oilseed yields, they are often imprecise and lengthy processes. Crops derived from transgenic approaches, on the other hand, have proven difficult to get to market due to negative public perception and onerous regulatory requirements. Genome editing, primarily using the clustered regularly interspaced short palindromic repeats/CRISPR-associated protein (CRISPR/Cas) platform, is a relatively recent addition to our plant breeding toolkit that allows the rapid generation of precise targeted genetic changes that can be indistinguishable from spontaneous mutations. In addition, the resulting plants can be made transgene-free with relative ease. While genome editing has been successfully used to modify a plethora of genes in the model plant Arabidopsis thaliana, the technology is only just taking off in oilseed crop species. This review discusses advances that have been made to-date using CRISPR/Cas-mediated genome editing of oilseed crops to improve plant productivity under favorable and sub-optimal environmental conditions, leading to increased seed yields or reduced losses. Furthermore, we also examine potential avenues for future enhancements in these traits using this molecular breeding tool.","PeriodicalId":10854,"journal":{"name":"Critical Reviews in Plant Sciences","volume":"39 1","pages":"195 - 221"},"PeriodicalIF":6.9,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/07352689.2020.1782568","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45415968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
