Contribution of Gamma amino butyric acid (GABA) to salt stress responses of Nicotiana sylvestris CMSII mutant and wild type plants

Contribution of polyamines and other related metabolites to the maintenance of zucchini fruit quality during cold storage

“…GABA metabolism is involved in different regulatory processes, including osmotic or pH regulation, bypass of the tricarboxylic acid cycle, and maintenance of C:N balance (Akcay et al, 2012). GABA is directly derived from glutamate, or indirectly from putrescine via a combination of DAO and aminobutyraldehyde dehydrogenase activities (Shelp et al, 2012c).…”

Allelopatic Potential of Dittrichia viscosa (L.) W. Greuter Mediated by VOCs: A Physiological and Metabolomic Approach

“…Among them, quaternary ammonium compounds [72–74] and amino acids such as proline, asparagine and γ-aminobutyric acid (GABA) [75–77] play a pivotal role in the recovery of plants from stress [77] such as osmotic stress [78–80]. In particular, proline accumulates to high levels in species adapted to arid and saline environments, in plant tissues withstanding severe desiccation, in response to allelochemicals [36, 62, 81, 82] and in cellular redox regulation, protecting proteins and membranes and scavenging reactive oxygen species [83, 84].…”

The impact of GABA in harpin-elicited biotic stress responses in Nicotiana tabaccum

“…Park et al (2010) emphasized multiple roles of GABA in P. syringae-plant interactions in relation to altered disease resistance. Salt stress effects were alleviated by GABA accumulation in Complex I dysfunctional tobacco CMSII mutants (Akç ay et al, 2012). Molina-Rueda et al (2015) proposed a model for GABA in vascular differentiation, defense and signaling in pine.…”
