Graphic to illustrate the role of Argonaute proteins (components of the RNA silencing machinery) in plant antiviral defenses. In this figure, OsAGO2 is significantly induced by infection with rice stripe virus and rice dwarf virus. Loss-of-function ago2 mutant lines lack antiviral activity, and AGO2 over-expression lines show increased antiviral activity.

Fig. 1.ABI5 coordinates growth–defense trade-offs by integrating signals from the TOR Complex 1 and ABA. A ‘tug-of-war’ between growth and defense signaling pathways converge at the ABA-sensitive transcription factor ABI5. Under stress, ABA binds to its receptor PYL, which then binds to and inhibits PP2C. This inhibition allows levels of phosphorylated SnRK2 to build up and activate ABA-sensitive transcription factors such as ABI5 (Cutler et al., 2010). Under growth-promoting conditions, TOR phosphorylates PYL, preventing it from de-repressing SnRK2. Both sides of the antagonism can function simultaneously, and they continually feedback to regulate the activity of the other. The canonical TOR effector TAP46 also protects ABI5 from dephosphorylation via PP2A, thereby stabilizing the ABA response. This mutual regulation between growth and defense ensures neither process overwhelms the other.

Experimental gable-roof high tunnel in Wooster, OH, USA (9.1 × 36.6 m; peak height, 4.1 m), oriented north–south, with double-polyethylene roof, single-polyethylene rollup sidewalls, and double-polycarbonate end walls. No active climate control. Air temperature was recorded 1.8 m aboveground at the tunnel center.
ML-based forecasting shows a strong potential for early warnings of high-temperature events and other agricultural decision support, including frost protection and scheduling of planting, harvesting, and irrigation. https://doi.org/10.21273/HORTTECH05825-25 #plantscience

Fig. 1 (shortened, full legend in paper): Phosphorus availability tunes root architecture through TOR signaling. Pathways are represented without implying temporal or spatial sequence. Positive and negative regulation is denoted by arrowheads and flat-ended lines, respectively. (A) Nutrient control of TOR signaling. The TOR complex 1 (TORC1) integrates multiple mineral nutrient signals, including sulfur (S), nitrogen (N), phosphorus (P), iron (Fe), and potassium (K). Sulfate is transported via SULTRs, activating TOR. Nitrate, imported through NRTs, stimulates TOR via the ROP2 GTPase. Phosphate uptake through PHTs enhances ARSK1 expression and activity, which phosphorylates RAPTOR1B, activating TOR. Conversely, phosphate limitation lifts repression of PSR1 and ARSK1, which inhibits TORC. Iron is taken up via IRTs and eventually influences TORC activity.
