“…TGA transcription factors in Arabidopsis are divided into five subclades (clade I: TGA1 and TGA4; clade II: TGA2, TGA5, and TGA6; clade III: TGA3 and TGA7; clade IV: TGA9 and TGA10; and clade V: TGA8, also known as PERIANTHIA/PAN; Gatz, 2013). Genetic studies show highly overlapping roles for TGA factors in plant defense, stress responses, and/or development (Gatz, 2013;Noshi et al, 2016). NPR1 constitutive interaction with clade II TGAs plays a major role since SAR is abolished in tga2 tga5 tga6 triple mutants, resulting in an npr1-like phenotype (Cao et al, 1994;Zhang et al, 2003).…”

Clade I TGACG-Motif Binding Basic Leucine Zipper Transcription Factors Mediate BLADE-ON-PETIOLE-Dependent Regulation of Development

ORCID IDs: 0000-0001-9461-4369 (M.K.); 0000-0001-7587-4392 (M.B.); 0000-0002-6496-3792 (S.R.H.).Lateral organs formed by the shoot apical meristem (SAM) are separated from surrounding stem cells by regions of low growth called boundaries. Arabidopsis (Arabidopsis thaliana) BLADE-ON-PETIOLE1 (BOP1) and BOP2 represent a class of genes important for boundary patterning in land plants. Members of this family lack a DNA-binding domain and interact with TGACG-motif binding (TGA) basic Leu zipper (bZIP) transcription factors for recruitment to DNA. Here, we show that clade I bZIP transcription factors TGA1 and TGA4, previously associated with plant defense, are essential cofactors in BOP-dependent regulation of development. TGA1 and TGA4 are expressed at organ boundaries and function in the same genetic pathways as BOP1 and BOP2 required for SAM maintenance, flowering, and inflorescence architecture. Further, we show that clade I TGAs interact constitutively with BOP1 and BOP2, contributing to activation of ARABIDOPSIS THALIANA HOMEOBOX GENE1, which is needed for boundary establishment. These studies expand the functional repertoire of clade I TGA factors in development and defense.

Salicylic acid (SA) is a key natural component that mediates local and systemic resistance to pathogens in many dicotyledonous species. However, its function is controversial in disease resistance in rice plants. Here, we show that the SA signaling is involved in both pathogen-associated-molecular-patterns triggered immunity (PTI) and effector triggered immunity (ETI) to Xanthomonas oryzae pv. Oryzae (Xoo) mediated by the recessive gene xa5, in which OsNPR3.3 plays an important role through interacting with TGAL11. Rice plants containing homozygous xa5 gene respond positively to exogenous SA, and their endogenous SA levels are also especially induced upon infection by the Xoo strain, PXO86. Depletion of endogenous SA can significantly attenuate plant resistance to PXO86, even to 86∆HrpXG (mutant PXO86 with a damaged type III secretion system). These results indicated that SA plays an important role in disease resistance in rice plants, which can be clouded by high levels of endogenous SA and the use of particular rice varieties. Bacterial blight (BB) caused by Xanthomonasoryzae pv. Oryzae (Xoo) is a serious bacterial disease in rice-growing areas and can reduce the rice yield by up to 50% in some areas of Asia 1. The most effective and economical management strategy for BB is the utilization of BB resistance genes in breeding. Of note, the rice-Xoo interaction has now become an important model system to study diseases in monocotyledonous plants 2. Approximately 44 rice bacterial blight resistance genes (BBR genes) have been identified to date 3,4. Of them, 10 genes, including Xa21,

Knockout mutants lacking TGA10 are more sensitive to flg22 treatment than wild-type plants (Noshi et al, 2016).

“…Although knockout mutants lacking TGA9 do not show any flg22 response defects, the double mutant tga9 tga10 shows reduced growth indicating increased pathogen susceptibility compared to either single mutant. This indicates a role for both TGA9 and TGA10 in sensitivity to flg22 (Noshi et al, 2016). Reactive oxygen species (ROS) are produced in response to flg22 treatment, and act as signaling molecules (O'Brien et al, 2012).…”

A Previously Undiscovered Role for Clade III TGA Basic Leucine Zipper Transcription Factors in BLADE-ON-PETIOLE Dependent Regulation of Plant Development

Boundaries that join lateral organs to the plant body are an important determinant of plant architecture. These specialized junctions originate within the shoot apex and control leaf shape, branching architecture, and abscission. Boundary patterning relies on a pair of BTB-ankyrin co-transcription factors encoded by BLADE-ON-PETIOLE 1 and 2 (BOP1/2). Members of this class bind to DNA indirectly, by interacting with other types of transcription factors, especially TGACG-motif binding (TGA) basic leucine zipper proteins. My works shows a previously undiscovered role for clade III TGA factors, previously associated with plant defense, in BOP-dependent plant development. This work uncovers a dual role for clade III TGAs in development and defense.
