“…Application of α-tocopherol, GB or SA did not alter rice phenology. This differs from findings of Oota (1975), and Datta & Nanda (1985), which state that SA application induces early flowering in duckweeds (Lemna gibba L.) and chenna millet (Panicum miliaceum L.). Salicylic acid induces flowering in plants by acting as a chelating agent (Oota, 1972).…”

The impacts of α-tocopherol, glycine betaine (GB) and salicylic acid (SA) applications on higher plants have been the subject of many studies, with special emphasis on oxidative stress tolerance under adverse conditions. However, little work has been carried out on rice responses to α-tocopherol, GB or SA under non-stress conditions, in which yield could potentially increased. This study determined the effects of α-tocopherol (2.3 kg ha -1 ), GB (2.0 kg ha -1 ) or SA (12.9 g ha -1) application on rice morphology, phenology and physiology under non-stress conditions. The applications did not affect production of tillers, biomass, phenology, or pollen germination; however, plant height, leaf characteristics and physiology, spikelet fertility (SF), panicle and grain characteristics and yield were affected. Plants treated with α-tocopherol, GB or SA showed 6%, 13% and 13.5% increases in grain yield as a result of decreased respiration and increased membrane integrity and SF.

“…Based on information available in the literature, it is evident that flowering is induced by chelating agents in Laminaceae40, 41 through the activity of benzoic acid42, 43 and other non‐chelating phenolic compounds 44. It was hypothesised that the free o ‐hydroxyl group of benzoic acid induces a metal‐chelating characteristic that favours flower induction 45–47. Moreover, it was concluded that additional flower‐inducing mechanisms may be heavily involved in this process 46, 47.…”

“…Indeed, a differential action of these compounds was observed according to the molecular structure as well on membrane processes (modification of membrane electrical potential ΔΨ), the metabolic chain (respiration), enzyme function (plasma membrane H + -ATPase activity), or more global processes such as alterations to organelles (mitochondria in particular) and the macroscopic response to external stimuli (osmocontractile cell reaction under touch of the organ, leading to drooping of the leaf) (Dédaldéchamp et al 2014, Rocher et al 2014, Saeedi et al 2013. Such a structure-activity relationship with this type of compound has already been reported on other plant metabolic processes such as thermogenesis (Raskin et al 1989) and flowering (Kaihara et al 1981, Oota 1975, indicating therefore that these compounds act through a very general mode of action. Therefore, the leaf pulvinus of M. pudica appears as a convenient experimental model to obtain a rapid result concerning the possible effect of a compound on cellular processes.…”

Early prediction of compound absorption by cells is of considerable importance in the building of an integrated scheme describing the impact of a compound on intracellular biological processes. In this scope, we study the structure-activity relationships of several benzoic acid-related phenolics which are involved in many plant biological phenomena (growth, flowering, allelopathy, defense processes). Using the partial least squares (PLS) regression method, the impact of molecular descriptors that have been shown to play an important role concerning the uptake of pharmacologically active compounds by animal cells was analyzed in terms of the modification of membrane potential, variations in proton flux, and inhibition of the osmocontractile reaction of pulvinar cells of Mimosa pudica leaves. The hydrogen bond donors (HBD) and hydrogen bond acceptors (HBA), polar surface area (PSA), halogen ratio (Hal ratio), number of rotatable bonds (FRB), molar volume (MV), molecular weight (MW), and molar refractivity (MR) were considered in addition to two physicochemical properties (logD and the amount of non-dissociated form in relation to pKa). HBD + HBA and PSA predominantly impacted the three biological processes compared to the other descriptors. The coefficient of determination in the quantitative structure-activity relationship (QSAR) models indicated that a major part of the observed seismonasty inhibition and proton flux modification can be explained by the impact of these descriptors, whereas this was not the case for membrane potential variations. These results indicate that the transmembrane transport of the compounds is a predominant component. An increasing number of implicated descriptors as the biological processes become more complex may reflect their impacts on an increasing number of sites in the cell. The determination of the most efficient effectors may lead to a practical use to improve drugs in the control of microbial attacks on plants.
