“…A similar decrease was apparent in the deep proteomics results for PIN-FORMED 7 (PIN7), which is also known to affect lateral root growth. Both PIN3 and 7 have important roles in establishing local auxin concentration maxima (Jang et al, 2018). The abundance of AUXIN RESISTANT 4 (AXR4), an ER protein that is responsible specifically for the distribution and localization of the influx carrier AUXIN RESISTANT 1 (AUX1), was also elevated slightly (Dharmasiri et al, 2006).…”

Proteome remodeling is a fundamental adaptive response, and proteins in complexes and functionally related proteins are often co-expressed. Using a deep sampling strategy we define core proteomes of Arabidopsis thaliana tissues with around 10 000 proteins per tissue, and absolutely quantify (copy numbers per cell) nearly 16 000 proteins throughout the plant lifecycle. A proteome-wide survey of global post-translational modification revealed amino acid exchanges pointing to potential conservation of translational infidelity in eukaryotes. Correlation analysis of protein abundance uncovered potentially new tissue-and agespecific roles of entire signaling modules regulating transcription in photosynthesis, seed development, and senescence and abscission. Among others, the data suggest a potential function of RD26 and other NAC transcription factors in seed development related to desiccation tolerance as well as a possible function of cysteine-rich receptor-like kinases (CRKs) as ROS sensors in senescence. All of the components of ribosome biogenesis factor (RBF) complexes were found to be co-expressed in a tissue-and age-specific manner, indicating functional promiscuity in the assembly of these less-studied protein complexes in Arabidopsis.Furthermore, we characterized detailed proteome remodeling in basal immunity by treating Arabidopsis seeldings with flg22. Through simultaneously monitoring phytohormone and transcript changes upon flg22 treatment, we obtained strong evidence of suppression of jasmonate (JA) and JA-isoleucine (JA-Ile) levels by deconjugation and hydroxylation by IAA-ALA RESISTANT3 (IAR3) and JASMONATE-INDUCED OXYGENASE 2 (JOX2), respectively, under the control of JASMONATE INSENSITIVE 1 (MYC2), suggesting an unrecognized role of a new JA regulatory switch in pattern-triggered immunity. Taken together, the datasets generated in this study present extensive coverage of the Arabidopsis proteome in various biological scenarios, providing a rich resource available to the whole plant science community.

“…4,5 This suggests that xylem-specific auxin accumulation produces the responses in xylem, consistent with the recent finding that inhibition of polar auxin transport affects xylem-specific auxin accumulation and xylem development. 6 JA regulates plant defenses against biotic and abiotic stresses. 7 JA is synthesized from linolenic acid via the octadecanoid pathway, after which it is metabolized into an isoleucine conjugate (JA-Ile).…”

“…Consistent with this, the PIN3 and PIN7 expression responsible for xylem patterning is activated by cytokinin (CK), yet JA antagonistically interacts with CK to modulate xylem development. 5,6,15 Therefore, CK-responsive PIN3 and PIN7 expression could be involved in JA-mediated xylem development in plants.…”

Jasmonic acid (JA) modulates plant development, growth, and responses to stress. Previously, we showed that in Arabidopsis thaliana, JA promotes the formation of extra xylem in roots, and mutant plants unable to express PIN-FORMED 3 (PIN3) and PIN7 formed extra xylem in the absence of exogenous JA. Those results suggested that JA modulates root xylem development by controlling PIN-mediated polar auxin transport. Consistent with this, treatment with an auxin transport inhibitor induced extra xylem formation. Here, we characterized the expression of PIN3 and PIN7 in JA-treated Arabidopsis plants. PIN3 expression was not altered in response to JA; by contrast, PIN7 expression was reduced by JA, which suggested that PIN7 is involved in JA-mediated xylem development. Indeed, overexpressing PIN7 suppressed the formation of extra xylem in response to JA. Based on these results, we propose that JA mediates xylem development by controlling polar auxin transport with PIN7 critically involved in this process.

24Proteome remodeling is a fundamental adaptive response and proteins in complex and 25 functionally related proteins are often co-expressed. Using a deep sampling strategy we 26 define Arabidopsis thaliana tissue core proteomes at around 10,000 proteins per tissue 27 and absolutely quantify (copy numbers per cell) nearly 16,000 proteins throughout the 28 plant lifecycle. A proteome wide survey of global post translational modification revealed 29 amino acid exchanges pointing to potential conservation of translational infidelity in 30 eukaryotes. Correlation analysis of protein abundance uncovered potentially new tissue 31 and age specific roles of entire signaling modules regulating transcription in 32 photosynthesis, seed development and senescence and abscission. Among others, the 33 data suggest a potential function of RD26 and other NAC transcription factors in seed 34 development related to desiccation tolerance as well as a possible function of Cysteine-35 rich Receptor-like Kinases (CRKs) as ROS sensors in senescence. All of the 36 components of ribosome biogenesis factor (RBF) complexes were co-expressed tissue 37 and age specifically indicating functional promiscuity in the assembly of these little 38 described protein complexes in Arabidopsis. Treatment of seedlings with flg22 for 16 39 hours allowed us to characterize proteome architecture in basal immunity in detail. The 40 results were complemented with parallel reaction monitoring (PRM) targeted 41 proteomics, phytohormone, amino acid and transcript measurements. We obtained 42 strong evidence of suppression of jasmonate (JA) and JA-Ile levels by deconjugation 43 and hydroxylation via IAA-ALA RESISTANT3 (IAR3) and JASMONATE-INDUCED 44 OXYGENASE 2 (JOX2) under the control of JASMONATE INSENSITIVE 1 (MYC2). 45 This previously unknown regulatory switch is another part of the puzzle of the as yet 46 understudied role of JA in pattern triggered immunity. The extensive coverage of the 47 Arabidopsis proteome in various biological scenarios presents a rich resource to plant 48 biologists that we make available to the community.49 50 51 52 53 Proteome biology is receiving increasing interest in the last years but still proves difficult 54 on a genome wide scale in plants. The proteome is the most fundamental active 55 determinant of an organism's phenotype and its landscape is large, complex and 56 dynamic, entailing changes in protein abundance, interaction, post translational 57 modification (PTM) and sub-cellular localization. 58 Steady state protein abundance at a certain time point is to a considerable part 59 determined by the abundance of its transcript and the latter's translation rate. Synthesis 60 is however only half of the equation governing protein abundance, indeed Arabidopsis 61 has more than 600 F-box proteins as components of diverse E3 ubiquitin ligase 62 complexes that direct protein degradation. Newer evidence has shown that post 63 transcriptional and translational mechanisms (Ponnala et al., 2014; Merchante et al., 64 2017) and...
