Micrografting techniques for testing long-distance signalling in Arabidopsis.
Grafting in species other than Arabidopsis has generated persuasive evidence for long-distance signals involved in many plant processes, including regulation of flowering time and shoot branching. Hitherto, such approaches in Arabidopsis have been hampered by the lack of suitable grafting techniques. Here, a range of micrografting methods for young Arabidopsis seedlings are described. The simpl...
متن کاملSystemic low temperature signaling in Arabidopsis.
When leaves are exposed to low temperature, sugars accumulate and transcription factors in the C-repeat binding factor (CBF) family are expressed, which, together with CBF-independent pathways, are known to contribute to the cold acclimation process and an increase in freezing tolerance. What is not known, however, is whether expression of these cold-regulated genes can be induced systemically ...
متن کاملA novel signaling pathway controlling induced systemic resistance in Arabidopsis.
Plants have the ability to acquire an enhanced level of resistance to pathogen attack after being exposed to specific biotic stimuli. In Arabidopsis, nonpathogenic, root-colonizing Pseudomonas fluorescens bacteria trigger an induced systemic resistance (ISR) response against infection by the bacterial leaf pathogen P. syringae pv tomato. In contrast to classic, pathogen-induced systemic acquire...
متن کاملMicrografting in Extensive Quantities
The exclusive use of very small grafts has moved from the experimental to the forefront. Dense packing of minigrafts of 1.5 mm or less in combination with one-or two-haired grafts offers the appearance of comparable density and undetectability, while using donor hair very efficiently. The use of smaller grafts in greater quantity offers many advantages normally unavailable with traditional larg...
متن کاملMethyl salicylate production and jasmonate signaling are not essential for systemic acquired resistance in Arabidopsis.
Systemic acquired resistance (SAR) develops in response to local microbial leaf inoculation and renders the whole plant more resistant to subsequent pathogen infection. Accumulation of salicylic acid (SA) in noninfected plant parts is required for SAR, and methyl salicylate (MeSA) and jasmonate (JA) are proposed to have critical roles during SAR long-distance signaling from inoculated to distan...
