In addition to its role in protein synthesis and the plant cells' response to environmental stresses, circumstantial evidence suggest that proline may also play a role in flowering and development both as a metabolite and as a signal molecule. Although there is a growing consensus that proline is of special importance throughout the reproductive phase (from flower transition to seed development) a general agreement on the molecular and genetic mechanisms proline is involved in, is yet to be established. In this paper we shall review and critically discuss most of the evidence supporting a role for proline in plant development, paying special attention to the recently reported role of proline in flower transition.

Poly(-lysine)--poly(ethylene glycol)--poly(-lysine) (PLys--PEG--PLys) triblock copolymers formed polyion complex (PIC) with poly(acrylic acid) (PAAc) or sodium poly(styrenesulfonate) (PSS), leading to the formation of flower micelle-type nanoparticles (Nano or Nano) with tens of nanometers size in water at a polymer concentration of 10 mg/mL. The flower micelles exhibited irreversible temperature-driven sol-gel transitions at physiological ionic strength, even at low polymer concentrations such as 40 mg/mL, making them promising candidates for injectable hydrogel applications. Rheological studies showed that the chain length of PLys segments and the choice of polyanions significantly impacted irreversible hydrogel formation, with PSS being superior to PAAc for the formation.

Flowering is initiated in response to environmental cues, with the photoperiod and ambient temperature being the main ones. The regulatory pathways underlying floral transition are well studied in but remain largely unknown in legumes. Here, we first applied an in silico approach to infer the regulatory inputs of four -like genes of the narrow-leafed lupin .

Adonis amurensis Regel et Radde is a remarkable and important spring ephemeral plant and gained considerable attention because of its remarkable medicinal properties. Extensive research has been conducted on its therapeutic applications, physical characteristics, flowering patterns, reproductive, cultural and molecular biology. However, there is a lack of comprehensive understanding regarding the metabolic changes associated with flower developmental stages.

Vascular smooth muscle cells (VSMCs) undergo metabolic pathway transitions, including aerobic glycolysis, fatty acid oxidation, and amino acid metabolism, which are important for their function. Metabolic dysfunction in VSMCs can lead to age-related vascular diseases. -GlcNAcylation, a nutrient-dependent posttranslational modification linked specifically to glucose metabolism, plays an important role in this context.
