“…Mutant of bes1-D is more susceptible to Botrytis cinerea infection than wild-type, while stable overexpression lines of PDF1.2a show improved resistance to B. cinerea. In response to B. cinerea invasion, the double mutant, bes1-D and PDF1.2a overexpression lines, is more similar to PDF1.2a overexpression lines than bes1-D (Liao et al, 2020). These genetic data support the antagonistic role of BES1 in JA mediated defense response.…”

“…BZR1 and ULP1a co-localize in the cytoplasm, and SUMOylation of BZR1 modulates its nuclear distribution ( Liao et al, 2020 ; Srivastava et al, 2020 ). While BL treatment increases nuclear-to-cytoplasmic (NP) ratio of wild-type BZR1, the NP ratio of BZR1 SUMO-deficient form is unchanged.…”

“…Recent data from Arabidopsis revealed the molecular mechanisms underlying BR-JA pathway crosstalk that mediate the growth-defense trade-off ( Figures 2A , C ). Liao et al (2020) discovered that BRs antagonize JA-activated defense mechanism via BES1, a master regulator in BR signaling pathway. Two routes in which BES1 represses JA-activated defense pathway were established.…”

“…The bes1-D mutant shows increased sensitivity to Spodoptera exigua ( Liao et al, 2020 ). Furthermore, the level of glycosynolates (GS), which functions downstream of JA, significantly decreases in bes1-D mutant as well as the expression of indolic GS synthesis genes.…”

Brassinosteroids (BRs) play pivotal roles in the regulation of many dimensions of a plant’s life. Hence, through extensive efforts from many research groups, BR signaling has emerged as one of the best-characterized plant signaling pathways. The key molecular players of BR signaling from the cell surface to the nucleus important for the regulation of plant growth and development are well-established. Recent data show that BRs also modulate plant responses to environmental stresses such as drought and pathogen infection. In this mini review, we present the recent progress in BR signaling specifically in the post-translational SUMO modification of BR’s master regulators, BES1/BZR1. We also discuss recent findings on the crosstalk between BR, UV light, and jasmonic acid signaling pathways to balance growth during light stress and pathogen infections. Finally, we describe the current update on the molecular link between BR signaling and intracellular auxin transport that essential for plant development.

“…In addition, some studies suggest that JA fine-tunes the growth-defense dilemma through crosstalk with other signaling pathways. The BRI1-EMS-SUPPRESSOR1 transcription factor controlled by Brassinosteroids was reported to participate in this process by antagonizing JA-activated plant defenses [105]. Moreover, the JAZ and MYC proteins interact with central proteins, such as DELLA, HY5, and IAA59 in other plant growth-related hormone-dependent pathways to fine tune defense and growth [106][107][108][109][110].…”

Plant viruses pose serious threats to stable crop yield. The majority of them are transmitted by insects, which cause secondary damage to the plant host from the herbivore-vector’s infestation. What is worse, a successful plant virus evolves multiple strategies to manipulate host defenses to promote the population of the insect vector and thereby furthers the disease pandemic. Jasmonate (JA) and its derivatives (JAs) are lipid-based phytohormones with similar structures to animal prostaglandins, conferring plant defenses against various biotic and abiotic challenges, especially pathogens and herbivores. For survival, plant viruses and herbivores have evolved strategies to convergently target JA signaling. Here, we review the roles of JA signaling in the tripartite interactions among plant, virus, and insect vectors, with a focus on the molecular and biochemical mechanisms that drive vector-borne plant viral diseases. This knowledge is essential for the further design and development of effective strategies to protect viral damages, thereby increasing crop yield and food security.
