Role of Plant Kinases in Combined Stress

Lignin, glutathione and kinases play important roles inPaspalum regnelliidefense against spittlebug (Mahanarva spectabilis) attack

“…Metabolic networks highlight two enzymes from the ascorbate-glutathione cycle, dehydroascorbate reductase (DHAR) and glutathione reductase (GR), that handle oxidative stress conferring plant tolerance but also regenerate AsA and GSH to maintain the redox state (Hasanuzzaman et al ., 2019; Dorion et al ., 2021). Furthermore, some important enzymes from the kinase family responsible for protein phosphorylation are constantly associated with stress tolerance (Patil & Senthil-Kumar, 2020). Some of these enzymes were identified in our data and can be good resistance targets: adenylate kinase and guanylate kinase.…”

“…These enzymes not only confer plant tolerance to stress but also participate in regenerating AsA and GSH to maintain the redox state (Dorion et al, 2021; Hasanuzzaman et al, 2019). Furthermore, enzymes from the kinase family, which are responsible for protein phosphorylation, have emerged as key players in stress tolerance mechanisms, contributing to the maintenance of cellular homeostasis (Dzeja and Terzic, 2009; Patil and Senthil-Kumar, 2020; Sekulic et al, 2002). Our analysis highlights two enzymes as potential resistance targets: adenylate kinase, which is involved in regulating salt stress in maize (Chen et al, 2022) and in supplying substrates for aluminum resistance in U. decumbens roots (Arroyave et al, 2018), and guanylate kinase, whose expression changes in response to armyworm herbivory in sugarcane, thereby assisting in the resistance process (Wang et al, 2021).…”
