Dose-Dependent Effect of Salicylates in a Moss, Funaria hygrometrica
18
TL;DR: Examination of the effects of exogenously supplied salicylic acid and acetylsalicylate on this bioassay system shows that salicylates can regulate growth and development in mosses, producing a dose-dependent inhibition of bud formation.

Abstract: Plant growth regulators now include more than the classic examples auxin, cytokinin, ethylene, and gibberellin, but little is known about the activity of these additional classes of molecules in nonvascular plants. The formation of buds by protonema of the moss Funaria hygrometrica is perhaps the best known and most fully characterized developmental system in the nonvascular plants. Examination of the effects of exogenously supplied salicylic acid and acetylsalicylate on this bioassay system shows that salicylates can regulate growth and development in mosses, producing a dose-dependent inhibition of bud formation. Other experiments show that this action is distinct from any direct effect on the well-known cytokinin stimulation of bud formation, occurs late in the process of bud formation, occurs prior to the stable commitment of nascent buds, and is not an effect on the outgrowth of young shoots. Because mosses are the sister clade to the vascular plants, these results suggest that the ability to perceive and transduce salicylate signals is an ancient feature of land plant physiology.

Effect of exogenous salicylic acid under changing environment: a review
TL;DR: Various intrinsic biosynthetic pathways, interplay of SA and MeSA, its long distance transport and signaling, and the effect of exogenous application of SA on bio-productivity, growth, photosynthesis, plant water relations, various enzyme activities and its effect on the plants exposed to various biotic and abiotic stresses are discussed.

Application of iron nanoparticles and salicylic acid in in vitro culture of strawberries ( Fragaria × ananassa Duch.) to cope with drought stress
TL;DR: It is found that iron, a micronutrient in plant growth and in vitro development, greatly influenced the plantlets’ growth parameters and other measured traits, indicating that the efficiency of tissue culture and in vivo culture of strawberries could be improved by increased application of iron in the form of nanoparticles.

Physcomitrella patens activates reinforcement of the cell wall, programmed cell death and accumulation of evolutionary conserved defence signals, such as salicylic acid and 12‐oxo‐phytodienoic acid, but not jasmonic acid, upon Botrytis cinerea infection
Inés Ponce de León,Eric A. Schmelz,Carina Gaggero,Alexandra Castro,Alfonso Alvarez,Marcos Montesano +5 more
TL;DR: The results suggest that, although conserved defence signals, such as SA and OPDA, are synthesized and are probably involved in the defence response of P. patens against B. cinerea infection, JA production appears to be missing, suggesting that jasmonate perception is present in mosses.
Interactive effect of salicylic acid on some physiological features and antioxidant enzymes activity in ginger (Zingiber officinale Roscoe).
TL;DR: The results support the idea that low SA concentrations (10–5 M) may induce nitrite reductase synthesis by mobilizing intracellular NO3− and can provide protection to nitrite reducing enzyme degradation in vivo in the absence of NO3–.
