“…Additionally, in dehydrovomifoliol, an OH group is situated at the C-4 position, whereas in loliolide, an OH group is situated at the C-1 and C-3 positions. Kobayashi [76] suggested that the OH group at the C-3 position of loliolide is responsible for its phytotoxic effects. For these reasons, the cress seedlings might exhibit greater sensitivity to loliolide than dehydrovomifoliol.…”

Albizia richardiana, a fast-growing, large deciduous tree belonging to the Fabaceae family, grows well in hot and humid areas but mainly grows in the tropics of the Old World. The medicinal and other uses of Albizia richardiana are well documented, but the phytotoxic effects of this tree have not yet been investigated. We conducted this study to investigate the phytotoxic activity of Albizia richardiana leaves and to identify growth inhibitory substances for controlling weeds in a sustainable way. Aqueous methanol extracts of Albizia richardiana leaves greatly suppressed the growth of cress and barnyard grass seedlings in a concentration- and species-dependent manner. Two phytotoxic substances were separated using several purification steps and characterized through spectral analysis as dehydrovomifoliol and loliolide. Dehydrovomifoliol and loliolide significantly arrested the seedling growth of cress in the concentrations of 0.1 and 0.01 mM, respectively. The extract concentrations needed for 50% growth inhibition (I50 values) of cress seedlings were 3.16–3.01 mM for dehydrovomifoliol and 0.03–0.02 mM for loliolide. The results suggest that these two allelopathic substances might play a vital role in the phytotoxicity of Albizia richardiana leaves.

“…infestans growth (i.e., d ‐tagatose and l ‐sorbose), while those with a different C3 spatial configuration do not (i.e., d ‐psicose and d ‐sorbose). Similarly, Kobayashi et al, (2010) confirmed the importance of α‐axial hydroxyl group at the C3 position of d ‐allose for the retarding activity on rice seedling growth. Thus, structural configurations of rare sugars may be responsible for competitive inhibition of key enzymes of the sugar metabolism, but further biochemical studies are required to verify interactions of rare sugars with sugar transporters and catalytic sites of metabolic enzymes.…”

“…Compared to pure D-allose, D-allose fatty acid esters have stronger biological activity because their carbon chains are hydrophobic, and therefore improve surface activity and membrane permeability [153][154][155]. The efficacy of D-allose fatty acid esters was further improved by prolonging the carbon chain of the fatty acid moiety, which significantly enhanced the inhibitory activity of 6-O-dodecanoyl-D-allose regarding the rice growth compared to octanoate and decanoate [156]. Moreover, it has been shown that the α-axial hydroxyl group at the C-3 location of D-allose ester played an important role in the plant growth inhibitory effect, since the β-hydroxy group at C-2 or C-4 did not significantly affect the inhibitory activity of D-allose ester [157].…”

Rare sugars are monosaccharides with a limited availability in the nature and almost unknown biological functions. The use of industrial enzymatic and microbial processes greatly reduced their production costs, making research on these molecules more accessible. Since then, the number of studies on their medical/clinical applications grew and rare sugars emerged as potential candidates to replace conventional sugars in human nutrition thanks to their beneficial health effects. More recently, the potential use of rare sugars in agriculture was also highlighted. However, overviews and critical evaluations on this topic are missing. This review aims to provide the current knowledge about the effects of rare sugars on the organisms of the farming ecosystem, with an emphasis on their mode of action and practical use as an innovative tool for sustainable agriculture. Some rare sugars can impact the plant growth and immune responses by affecting metabolic homeostasis and the hormonal signaling pathways. These properties could be used for the development of new herbicides, plant growth regulators and resistance inducers. Other rare sugars also showed antinutritional properties on some phytopathogens and biocidal activity against some plant pests, highlighting their promising potential for the development of new sustainable pesticides. Their low risk for human health also makes them safe and ecofriendly alternatives to agrochemicals.
