Defensive forwards: stress-responsive proteins in cell walls of crop plants

Abstract

12As the vital component of plant cell wall, proteins play important roles in stress response 13 through modifying wall structure and involving in wall integrity signaling. However, the 14 potential of cell wall proteins (CWPs) in improvement of crop stress tolerance has probably 15 been underestimated. Recently, we have critically reviewed the predictors, databases and 16 cross-referencing of subcellular locations of possible CWPs in plants (Briefings in 17 Bioinformatics 2018;19:1130-1140). In this study, taking maize (Zea mays) as an example, 18 we retrieved 1873 entries of probable maize CWPs recorded in UniProtKB. As a result, 863 19 maize CWPs are curated and classified as 59 kinds of protein families. By referring to GO 20 annotation and gene differential expression in Expression Atlas, we highlight the potential of 21 CWPs as defensive forwards in abiotic and biotic stress responses. In particular, several 22 CWPs are found to play key roles in adaptation to many stresses. String analysis also reveals 23 possibly strong interactions among many CWPs, especially those stress-responsive enzymes. 24The results allow us to narrow down the list of CWPs to a few specific proteins that could be 25 candidates to enhance maize resistance. 26

Drought Responsive Putative Marker-Trait Association in Tall Fescue as Influenced by the Presence of a Novel Endophyte

“…The aspartyl protease AED3 ( BRADI_1g19070 ), an orthologs of Arabidopsis AtAED3 , is a cell wall protein expressed in growing organs, such as young leaves and apical internodes of Brachypodium , rice, and Arabidopsis ( Douche et al, 2013 ). As a cell wall protein, the AED3 may have a role in abiotic stress response in maize by modifying cell wall structure and being involved in cell wall integrity signaling ( Niu and Wang, 2020 ).…”

Post-Synthetic Reduction of Pectin Methylesterification Causes Morphological Abnormalities and Alterations to Stress Response in Arabidopsis thaliana

“…Plant cell wall proteins (CWP) play important roles in various abiotic and biotic stress responses, and some CWPs were found to be key factors in adaptation to many stresses [ 10 ]. Signaling pathways for both abiotic and biotic stresses reveal intersections between responses and share regulatory principles [ 11 ].…”
