“…Long non‐coding RNAs (lncRNAs) are a class of regulatory RNA molecules that have captured the attention of researchers in recent years due to their diverse roles in development, physiological and pathological processes. 1 , 2 , 3 , 4 , 5 , 6 Unlike the conventional protein‐coding genes, which have been extensively studied and characterized, lncRNAs were once considered ‘genomic noise’ or transcriptional byproducts with little functional relevance. However, with the advances in genomics and transcriptomics, as well as the establishment of multiple databases and related resources, 7 , 8 , 9 the intricate world of lncRNAs has been revealed, becoming an emerging frontier field in biomedical sciences and agriculture.…”

“…Research conducted over the last few decades shows that, apart from specific regulatory proteins, such as LAFL and PKL or VAL1, the participation of phytohormones in the control of seed filling processes is also very significant [34,35]. The most important role is attributed to the interdependence between gibberellic acid (GA) and abscisic acid (ABA) [36][37][38].…”

The maturation of seeds is a process of particular importance both for the plant itself by assuring the survival of the species and for the human population for nutritional and economic reasons. Controlling this process requires a strict coordination of many factors at different levels of the functioning of genetic and hormonal changes as well as cellular organization. One of the most important examples is the transcriptional activity of the LAFL gene regulatory network, which includes LEAFY COTYLEDON1 (LEC1) and LEC1-LIKE (L1L) and ABSCISIC ACID INSENSITIVE3 (ABI3), FUSCA3 (FUS3), and LEC2 (LEAFY COTYLEDON2), as well as hormonal homeostasis–of abscisic acid (ABA) and gibberellins (GA) in particular. From the nutritional point of view, the key to seed development is the ability of seeds to accumulate large amounts of proteins with different structures and properties. The world’s food deficit is mainly related to shortages of protein, and taking into consideration the environmental changes occurring on Earth, it is becoming necessary to search for a way to obtain large amounts of plant-derived protein while maintaining the diversity of its origin. Yellow lupin, whose storage proteins are conglutins, is one of the plant species native to Europe that accumulates large amounts of this nutrient in its seeds. In this article we have shown the key changes occurring in the developing seeds of the yellow-lupin cultivar Taper by means of modern molecular biology techniques, including RNA-seq, chromatographic techniques and quantitative PCR analysis. We identified regulatory genes fundamental to the seed-filling process, as well as genes encoding conglutins. We also investigated how exogenous application of ABA and GA3 affects the expression of LlLEC2, LlABI3, LlFUS3, and genes encoding β- and δ-conglutins and whether it results in the amount of accumulated seed storage proteins. The research shows that for each species, even related plants, very specific changes can be identified. Thus the analysis and possibility of using such an approach to improve and stabilize yields requires even more detailed and extended research.

“…The effects of abscisic acid and gibberellins on the expression of genes involved in the control of conglutins have been studied and discussed [4]. The involvement of phytohormones in the control of seed filling is considered very important [30,31]. The most significant role is attributed to the interactions between GA and ABA [32,33].…”
