“…In contrast, soybean exhibits ten duplication patterns among glyoxalase genes (GLYI and GLYII) [ 14 ], whereas five GLYI and one GLYII gene have reported such occurrences in Medicago [ 60 ]. These duplication events in plants have led to gene gain/loss and confer abiotic stress modulation [ 63 ].…”

Methylglyoxal (MG) is a highly cytotoxic molecule produced in all biological systems, which could be converted into non-toxic D-lactate by an evolutionarily conserved glyoxalase pathway. Glutathione-dependent glyoxalase I (GLYI) and glyoxalase II (GLYII) are responsible for the detoxification of MG into D-lactate in sequential reactions, while DJ-1 domain containing glyoxalase III (GLYIII) catalyzes the same reaction in a single step without glutathione dependency. Afterwards, D-lactate dehydrogenase (D-LDH) converts D-lactate into pyruvate, a metabolically usable intermediate. In the study, a comprehensive genome-wide investigation has been performed in one of the important vegetable plants, tomato to identify 13 putative GLYI, 4 GLYII, 3 GLYIII (DJ-1), and 4 D-LDH genes. Expression pattern analysis using microarray data confirmed their ubiquitous presence in different tissues and developmental stages. Moreover, stress treatment of tomato seedlings and subsequent qRT-PCR demonstrated upregulation of SlGLYI-2, SlGLYI-3, SlGLYI-6A, SlGLYII-1A, SlGLYII-3B, SlDJ-1A, SlDLDH-1 and SlDLDH-4 in response to different abiotic stresses, whereas SlGLYI-6B, SlGLYII-1B, SlGLYII-3A, SlDJ-1D and SlDLDH-2 were downregulated. Expression data also revealed SlGLYII-1B, SlGLYI-1A, SlGLYI-2, SlDJ-1D, and SlDLDH-4 were upregulated in response to various pathogenic infections, indicating the role of MG detoxifying enzymes in both plant defence and stress modulation. The functional characterization of each of these members could lay the foundation for the development of stress and disease-resistant plants promoting sustainable agriculture and production.

Maize and wheat are two important cereal crops for the food security of the world population. However, constant climate change and the intensification of anthropic activities have intensified the emergence of stressful environmental in the various agricultural production systems around the world. Therefore, in this study we evaluate the chlorophyll content, photosynthesis, transpiration and grain yield of maize and wheat crops exposed to soil salinity, drought and high temperatures and determine the damage intensity of these stressing conditions and the theoretical multifactorial damage intensity. Field experiments were conducted during the 2022 and 2023 agricultural seasons in the Yaqui Valley, Sonora, Mexico. The treatments consisted of the cultivation of maize and wheat in three stressful production environments (soil salinity, drought and high temperatures) and a non‐stressful production environment (Control), with four repetitions. The tolerance and intensity index of abiotic stresses, as well as the intensity of theoretical multifactorial stress (salinity, drought and high temperatures), for morphological traits and grain yield, were calculated. The results reported that physiological traits and yield of maize and wheat are severely affected by drought stress conditions. High temperatures are the second abiotic stress factor that most limits physiological traits and grain yield of maize and wheat crops, being more harmful than soil salinity. The theoretical multifactorial stress has a greater negative impact on the yield of the elite maize and wheat varieties. The sum of a stressful environmental factor increases the intensity of multifactorial stress on grain yield of both cereal crops, especially for maize crop.
