Abstract

Abiotic and biotic stresses are the major factors that negatively impact plant growth. In response to abiotic environmental stresses such as drought, plants generate resistance responses through abscisic acid (ABA) signal transduction. In addition to the major role of ABA in abiotic stress signaling, ABA signaling was reported to downregu- late biotic stress signaling. Conversely recent findings provide evidence that initial activation of plant immune signaling inhibits subsequent ABA signal transduction. Stimulation of effector-triggered disease response can interfere with ABA signal transduction via modulation of internal calcium-dependent signaling pathways. This review overviews the interactions of abiotic and biotic stress signal transduction and the mechanism through which stress surveillance system operates to generate the most efficient resistant traits against various stress condition.

COVER PICTURE
The Target of Rapamycin Complex (TORC) is a central regulatory hub in eukaryotes, which is well conserved in diverse plant species, including tomato (Solanum lycopersicum). Inhibition of TORC genes (SlTOR, SlLST8, and SlRAPTOR) by VIGS (virus-induced gene silencing) results in early fruit ripening in tomato. The red/ orange tomatoes are early-ripened TORC-silenced fruits, while the green tomato is a control fruit. Top, left, control fruit (TRV2-myc); top, right, TRV2-SlLST8; bottom, left, TRV2-SlTOR; bottom, right, TRV2-SlRAPTOR(Choi et al., pp. 660-672).
