Summary: Functional analysis of the promoter region of the Lupinus luteus cytoplasmic cyclophilin gene revealed that cis-elements located between -1055 and -846 bp are crucial for gene expression in root nodules. Mutations in certain motifs abolished GUS expression, while others still activated it in specific regions of the nodules.

Summary: The study aimed to evaluate the seed yield, seed chemical composition, weed infestation of yellow lupine, and the soil organic C and total N contents in different tillage systems. The experiment revealed that conventional tillage resulted in higher seed yield due to increased plant, pod, and seed numbers. Additionally, the tillage systems influenced the composition of seeds, with ash content increasing and potassium content decreasing in the no-till system. Weed infestation was higher in reduced tillage compared to conventional and no-till systems, while organic C and total N content in the soil were higher in reduced tillage and no-till systems compared to conventional tillage.

Summary: Lupine seed shows significant differences in nutritional composition between species and geographical ecotypes, with white lupine having the highest protein and oleic acid content, while yellow lupine ecotypes vary greatly in oleic and linoleic acid content. The lipid and phenolic profiles of lupine seeds are highly influenced by ecological factors, with some ecotypes showing unique compounds and antioxidant activities.

Summary: The transition from juvenile to adult phase is a crucial period in a plant's life cycle. This transition is regulated by the decrease in miR156/157 levels and the increase in activity of SPL proteins. In Arabidopsis, this transition is associated with changes in leaf shape, particularly an increase in leaf blade length to width ratio. In this study, the researchers showed that ectopic expression of SPL9 and SPL13 results in enlarged and elongated leaves, similar to the blade-on-petiole1 (bop1) bop2 double mutant. They found that BOP1/BOP2 expression is down-regulated in successive leaves, which correlates with the amount of miR156 and is antagonistic to the expression of SPL9 and SPL13. SPL9 and SPL13 directly bind to the promoters of BOP1/BOP2 to repress their expression, leading to delayed establishment of proliferative regions in leaves and promoting more blade outgrowth while suppressing petiole development.

Summary: This study investigates the role of the Flowering locus T (FT) gene in yellow lupin in reducing vernalization and photoperiod requirements. The study found deletions in the promoter regions of FT homologues, with a deletion in LlutFTc1 linked to early phenology and vernalization independence, and indels in LlutFTa1a and LlutFTc2 associated with photoperiod responsiveness. Comparative mapping revealed convergence of FTc1 indel evolution in two Old World lupin species, addressing both artificial selection during domestication and natural adaptation to short season environmental conditions.

Summary: This study characterized the Ustilago maydis effector protein Jasmonate/Ethylene signaling inducer 1 (Jsi1), showing its interaction with plant corepressor TPL/TPR proteins and activation of the ERF branch in the JA/ET signaling pathway. The induction of the ERF branch by Jsi1 leads to increased susceptibility to biotrophic pathogens in plants. The identification of EAR-motif-containing effector candidates from various fungal species suggests a convergent evolution of effectors modulating the TPL/TPR corepressor hub.

Summary: Research on sphingolipids in plant plasma membranes suggests that hydroxyl groups in long-chain base moieties play a crucial role in interactions with sterols during microdomain formation. Mutants lacking LCB C-4 hydroxylase S4H in Physcomitrium patens exhibit global changes in sphingolipid composition, highlighting the importance of S4H in the development of nonvascular plants. Physcomitrium patens serves as a valuable model for studying the diversification of plant sphingolipids due to its simple anatomy which facilitates visualization of physiological processes in biological membranes.

Summary: This study used immunofluorescence techniques to investigate the dynamic changes in cell wall compounds of lupine root nodules and flower abscission zone (AZ) under drought conditions. The results showed upregulation of extensins, galactans, arabinans, xylogalacturonan, and xyloglucans in both nodules and the AZ. Additionally, modifications in the localization of high- and low-methylated homogalacturonans and arabinogalactan proteins were detected in nodules.

Summary: In this study, the researchers investigated the role of lipid-related enzymes and lipid-derived plant hormones in the flower abscission zone (AZ) of yellow lupine under drought conditions. They found that drought-induced lipid peroxidation in the AZ cells, leading to the upregulation of phospholipase D, lipoxygenase, and the accumulation of jasmonic acid (JA). They also observed the key steps of JA conjugation and signaling in response to drought stress. Overall, the activation of AZ during flower abscission is closely associated with lipid modifications and the induction of JA-related signaling pathways.

Summary: This study investigated how variations in nitrogen nutrition affected the metabolome and proteome of xylem sap, as well as the growth of the xylem endophyte Brennaria salicis and the transcriptional re-wiring of leaf defenses in poplar. The results showed that nitrogen nutrition had a significant impact on the composition of xylem sap, leading to changes in protein and metabolite abundances. These changes in xylem composition also affected the growth of the xylem endophyte and the transcriptional landscape of leaves, influencing plant defenses.

Summary: Understanding the mechanisms behind the activation of the abscission zone (AZ) in plants is important for improving crop yield and economic importance. The role of the INFLORESCENCE DEFICIENT IN ABSCISSION protein, particularly its functional fragment, EPIP peptide, has been studied. In this study, the impact of EPIP on ultrastructural changes, hormonal abscission stimulators, and phosphoproteins in the AZ of Lupinus luteus flowers was analyzed. The results showed that EPIP induced distinct modifications in the AZ, including upregulation of cell activity, degradation processes, and possible autophagy. EPIP also stimulated the biosynthesis of abscisic acid and ethylene in AZ cells, and phosphorylation of proteins was observed. Overall, this study provides new insights into the regulatory function of EPIP in abscission and offers opportunities to reduce excessive flower abscission in lupine.

Summary: Yellow lupine is an economically important crop and has been a great model for abscission processes due to extreme flower abortion in the abscission zone (AZ). AZ activation involves modifications of cell walls, membranes, and cellular structure. This study reveals lipid-associated changes, including upregulation of peroxidase in naturally active AZs, indicating disruption of redox balance and/or lipid peroxidation. Lipid-related processes also involve enzymes like lipase and LOX, as well as the accumulation of jasmonates with higher biological activity in flower AZ activation.

Summary: Triacylglycerols (TAGs) serve as the most important storage form of energy and carbon in eukaryotic cells and are essential macronutrients in animal and human diet, as well as major feedstock for industrial and energetic sectors. Oilseed crops are the primary source of TAGs and edible oils. Advances in research on plant lipid metabolism have provided insights into the molecular networks governing not only TAGs, but also other seed lipids, such as wax esters, sterols, and sphingolipids, contributing to a better understanding of the complex lipid web in oilseeds.
