“…The 10 Arabidopsis pPLAs are grouped into three subfamilies, pPLAI, pPLAII (α, β, γ, δ, and ε), and pPLAIII (α, β, γ, and δ). pPLAI has the highest homology to animal calcium-independent iPLA 2 ( Winstead et al , 2000 ; Holk et al , 2002 ) and is implicated in plant response to pathogen infection ( Yang et al , 2007 ) and auxin ( Effendi et al , 2014 ). AtpPLAIIα negatively regulates the production of oxylipins, such as jasmonates, and plays a role in cell death ( La Camera et al , 2009 ) and drought tolerance ( La Camera et al , 2005 ; Yang et al , 2012 ).…”

“…A knockdown mutant of patatin-related phospholipase A-I (ppla-I-1) was shown to have delayed gravitropic responses in roots, hypocotyls, and flower stalks (Scherer and Pietrzyk 2014). A possible reason for this is that the enzyme mediates auxin-induced gene expression (Effendi et al 2014).…”

Molecular mechanisms of gravity perception and signal transduction in plants

Gravity is one of the environmental cues that direct plant growth and development. Recent investigations of different gravity signalling pathways have added complexity to how we think gravity is perceived. Particular cells within specific organs or tissues perceive gravity stimulus. Many downstream signalling events transmit the perceived information into subcellular, biochemical, and genomic responses. They are rapid, non-genomic, regulatory, and cell-specific. The chain of events may pass by signalling lipids, the cytoskeleton, intracellular calcium levels, protein phosphorylation-dependent pathways, proteome changes, membrane transport, vacuolar biogenesis mechanisms, or nuclear events. These events culminate in changes in gene expression and auxin lateral redistribution in gravity response sites. The possible integration of these signalling events with amyloplast movements or with other perception mechanisms is discussed. Further investigation is needed to understand how plants coordinate mechanisms and signals to sense this important physical factor.

“…We chose rapidly responding genes IAA2 , IAA3 , IAA11 , IAA14 , IAA19 , IAA20 , GH3-5 , SAUR9 , SAUR15 , and SAUR23 and PIN genes PIN1 , PIN2 , PIN3 , and PIN5 to test for the role of ABP1 on the control of gene expression ( Effendi and Scherer, 2011 ; Effendi et al ., 2011 2013 2014 ; Labusch et al 2013 ). In the wt most marker genes were up-regulated after 10min of auxin application, whereas IAA3 , IAA20 , and the PIN genes were unchanged.…”

“…The ABP1 / abp1 plants were in the Ws background ( Chen et al , 2001b ) where a deletion in phyD renders this gene non-functional ( Aukermann et al ., 1997 ). The lack of a phyD gene influences early flowering ( Effendi et al , 2014 ). We observed that abp1 mutants had longer and wider leaf blades ( Fig.…”
