LITERATURE
gene PME34 is highly expressed in guard cells and in response to the phytohormone abscisic acid
isoform PME3 is induced upon infection with Botrytis cinerea and Pectobacterium carotovorum. The enzyme expression is induced upon herbivore attack as a defense mechanism
meta-analysis of biotic stress responsive expression of Oryza sativa PMEs. A number of OsPME genes are transcriptionally responsive to drought, heat, and anaerobic stresses while a few OsPME genes are up- or downregulated by salt and cold stresses. Based on the microarray data, similar expression patterns of OsPMEs are found in response to Magnaporthe grisea and Xanthomonas oryzae pv. oryzae, which cause rice blast and rice bacterial blight diseases, respectively. OsPME2 and 28 show elevated transcript levels in response to both pathogens. More dynamic transcriptional regulation of OsPMEs is found in response to rice stripe virus and brown planthopper. Nine OsPME genes (OsPME9, 15, 16, 20, 27, 28, 34, 41, and 43) are significantly upregulated whereas five OsPME genes (OsPME2, 6, 7, 11, and 17) are downregulated in response to rice stripe virus. Eight OsPME genes (OsPME2, 6, 8, 10, 17, 27, 28, and 32) are significantly upregulated whereas five OsPME genes (OsPME9, 15, 16, 19, and 36) are downregulated in response to brown planthopper
-
most pectin methylesterase genes from Phytophthora capsici present a decreasing trend of expression from 1 to 5 dpi in tomato fruits. In cucumber fruits, expression levels decrease from 5 to 7 dpi
pectin methylesterase expression decreases during the color change period in fruit ripening
-
pectin methylesterase expression increases at the end of fruit ripening
-
pectin methylesterase expression is positively regulated by cAMP receptor protein-like protein and RpfF
-
salt stress significantly decreases the PME31 expression, pme31 mutants expression is more affected
the enzyme is activated in response to heat shock. Pectin methylesterae activity during the 40°C treatment (2 h) is higher, by about 2.2fold, than that with the 28°C control treatment
-
the expression levels of the pectin methylesterase genes from Phytophthora capsici increase from 1 to 7 dpi in pepper. In fruits from pepper and tomato fruits, peaks are reached at 7 dpi. In cucumber fruits, each gene shows minor expression levels from 1 to 3 dpi and exhibits definite peaks at 5 dpi
upon infection, Pectobacterium carotovorum and Botrytis cinerea induce in Arabidopsis a rapid expression of isoform PME3
