The identity of membranes and their dynamic operations at membrane locations provide essential signals to control membrane transport, signaling, and communication. In diverse eukaryotes, particularly plants, the regulation of membrane identity changes and dynamic surface processes remains a significant area of unanswered questions, especially pertaining to the roles of protein interaction complexes comprised of peripheral and integral membrane proteins. Within the realm of eukaryotes, a conserved class of peripheral membrane proteins, the SEC14L-PITPs, includes SEC14-like phosphatidylinositol transfer proteins. These proteins’ shared SEC14 domain plays a vital role in membrane identity and regulation of trafficking processes. This domain facilitates the detection, binding, transportation, and exchange of lipophilic molecules like phosphoinositides and other lipid-soluble substances between membranes. SEC14L-PITPs exhibit a simple SEC14 protein structure in all examined organisms, or a modular multi-domain protein structure in animals and streptophytes (inclusive of charales and land plants). The functional roles of SEC14L-PITPs, particularly those of the multi-domain SEC14L-PITPs within the SEC14-nodulin and SEC14-GOLD groups (PATELLINs, PATLs in plants), are presented here. SEC14L-PITPs’ diverse roles in plants extend from membrane trafficking to influencing overall organismal fitness. The structural features of SEC14L-PITPs, their capability to bind both phospholipids and other lipophilic compounds, and their role in regulating complex cellular activities via protein-membrane interactions are the main subjects of our investigation.
Sainfoin (Onobrychis spp.), a perennial legume known for its forage value, is also being explored as a source of potential perennial pulses for human consumption. Sainfoin’s dual application forms the bedrock of various research and breeding initiatives, aiming to enhance sainfoin strains for both forage and legume crops. This pursuit is generating intricate datasets characterizing high-dimensional traits in the post-genomics era. To allow a variety of user groups, including breeders selecting for forage and those prioritizing edible seeds, to make use of these substantial datasets, it is essential to create shared ontologies and user-friendly platforms for accessing them. Crop-specific trait ontologies were hosted on Crop Ontology, a platform established in 2008 by the Consortium of International Agricultural Research Centers (CGIAR), to support standardized plant breeding databases. Our current research elucidates the sainfoin crop ontology (CO). An exhaustive review of the literature was carried out to produce a complete catalog of traits measured and recorded in studies of sainfoin. Because of the variability in measuring plant attributes via different methodologies and scales, it was concluded that a complete description of sainfoin’s range of variation necessitates 98 variables, wherein each represents the combination of the plant trait, the method of measurement, and its scale. The variables intended for inclusion in the sainfoin CO were formatted and standardized according to the guidelines supplied here. Among the 98 variables, a total of 82 traits were identified, encompassing four categories: 24 agronomic, 31 morphological, 19 associated with seed and forage quality, and 8 phenological. hif signals Beyond the developed variables, a plan for the development and submission of new traits for the sainfoin company has been prepared.
The particular pigments present inside a plant are the key to understanding the range of colors found in its flowers. Angiosperm anthocyanins, the most abundant flavonoid pigments, generate a diverse array of colors, from red-magenta to blue-purple, resulting from the respective biosynthesis of cyanidin and delphinidin. To enhance commercial prospects in the floriculture industry, novel varieties need to excel in floral coloration, but many plant species are naturally bound to a specific color range, genetically determined. Ornamental plants frequently lack blue varieties, a deficiency stemming from the inaction of key biosynthetic enzymes essential for delphinidin production. Among the many plants, the poinsettia, (Euphorbia pulcherrima Willd.), provides a captivating example. Klotzsch, the ornamental plant, a native of Mexico, is synonymous with Christmas. The diverse array of colors found in its bracts, which are essentially modified leaves storing reddish pigments primarily cyanidin and secondarily pelargonidin, is the reason for its immense popularity. Commercial success for this plant hinges on the introduction of new varieties; although consumers appreciate the standard red, they are also increasingly looking to poinsettias with fresh, novel, and innovative colors. Earlier explorations into the subject have showcased the potential for modulating flower coloration through the metabolic engineering of the anthocyanin biosynthetic pathway and plant tissue culture methods in a range of decorative plant species. Genetically modified flowers, specifically roses, carnations, and chrysanthemums, display a prominent bluish coloration due to a significant and exclusive concentration of delphinidin. Possible genetic engineering applications in *E. pulcherrima* concerning the anthocyanin biosynthetic pathway are explored, involving the introduction of one or more foreign delphinidin biosynthetic genes under the control of a pathway-specific promoter. Genome editing is also considered as an alternative for altering bract color. Beyond the primary methods, complementary strategies, including the careful selection of cultivars providing ideal intracellular environments for delphinidin accumulation, and the introduction of genes coding for anthocyanin-modifying enzymes or transcription factors that favor bluer coloration in flowers, are also evaluated.
Plant growth encounters a major constraint in the form of salt stress, an adverse environmental factor. Employing nitrogen as a treatment is an effective method for lessening the negative effects of salt on plant physiology. A study on the nitrogen application method for mitigating salt stress in rapeseed seedlings involved a pot experiment. Nitrogen was applied at four levels (0, 0.01, 0.02, and 0.03 g N per kg soil, labelled N0, N1, N2, and N3 respectively), while subjecting plants to either no salt (0 g NaCl per kg soil, S0) or salt stress (3 g NaCl per kg soil, S1). Analysis of the results revealed that salt stress conditions led to a considerable increase in sodium content (23653%) and reactive oxygen species (ROS), particularly hydrogen peroxide (H2O2) (3026%), which consequently triggered cell membrane lipid peroxidation, as indicated by a significant rise in malondialdehyde (MDA) (12232%), and concomitantly decreased the photosynthetic rate (1559%), culminating in impaired plant growth, marked by shorter plants, thinner root systems, reduced leaf surfaces, and decreased dry weight. Improved plant growth was achieved through nitrogen application, and this enhancement was stronger under salt stress than without. This signifies a heightened sensitivity to nitrogen in salt-stressed rapeseed seedlings, indicating the importance of nitrogen for supporting plant growth. Nitrogen-supplemented seedlings subjected to salt stress demonstrated a reduction in reactive oxygen species, an augmentation in photosynthesis, an increase in antioxidant enzymes such as catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), and ascorbic acid (AsA), and a greater buildup of osmotic substances like soluble proteins, soluble sugars, and proline, in comparison to control seedlings lacking nitrogen. In salt-stressed environments, the nitrogen application rate of N2 showed the greatest improvement, whereas applications beyond this level hindered nitrogen metabolism and lessened the observed improvement. The findings of this study suggest that moderate nitrogen application can promote improvements in photosynthesis, antioxidant production, and osmoregulation, thereby alleviating the detrimental effects of salt stress on rapeseed seedlings.
