The effects of 2,4-dichlorophenoxyacetic acid (2,4-D), gibberellic acid (GA), and abscisic acid (ABA) on the morphogenesis of gametophytes of Lygodium japonicum growing as longer-than-broad biplanar plates in red light and as broader-than-long biplanar plates in blue light were studied. Addition of 2,4-D or GA to the medium induced a change in the form of gametophytes from biplanar to filamentous in red light. Gametophytes growing in a medium containing 2,4-D in blue light were longer than broad, very much like gametophytes growing in the basal medium in red light. Although ABA generally retarded the growth of gametophytes in both light regimes, its presence in a medium containing 2,4-D nullified the effect of the latter, causing gametophytes to become plate-like in red light and short and stunted in blue light. Changes in the morphology of gametophytes induced by growth hormones were accompanied by corresponding changes in their length:width ratio and cell number.

Positive-sense RNA viruses have a small genome with very limited coding capacity and are highly reliant on host factors to fulfill their infection. However, few host factors have been identified to participate in wheat yellow mosaic virus (WYMV) infection. Here, we demonstrate that wheat (Triticum aestivum) light-induced protein (TaLIP) interacts with the WYMV nuclear inclusion b protein (NIb). A bimolecular fluorescence complementation (BIFC) assay displayed that the subcellular distribution patterns of TaLIP were altered by NIb in Nicotiana benthamiana. Transcription of TaLIP was significantly decreased by WYMV infection and TaLIP-silencing wheat plants displayed more susceptibility to WYMV in comparison with the control plants, suggesting that knockdown of TaLIP impaired host resistance. Moreover, the transcription level of TaLIP was induced by exogenous abscisic acid (ABA) stimuli in wheat, while knockdown of TaLIP significantly repressed the expression of ABA-related genes such as wheat abscisic acid insensitive 5 (TaABI5), abscisic acid insensitive 8 (TaABI8), pyrabatin resistance 1-Llike (TaPYL1), and pyrabatin resistance 3-Llike (TaPYL3). Collectively, our results suggest that the interaction of NIb with TaLIP facilitated the virus infection possibly by disturbing the ABA signaling pathway in wheat.

Accepted 29 October 2013. Abscisic acid (ABA) plays a key role in modulating plant responses to different biotic and abiotic stresses. However, the effect of ABA on virus infection is not fully understood. Here, we describe the effects of the ABA pathway on the accumulation of Bamboo mosaic virus (BaMV) and Cucumber mosaic virus (CMV) in two different hosts: Arabidopsis thaliana and Nicotiana benthamiana. We report that ABA2 plays a critical role in the accumulation of BaMV and CMV. Mutants downstream of ABA2 (aao3, abi1-1, abi3-1, and abi4-1) were susceptible to BaMV, indicating that the ABA pathway downstream of ABA2 is essential for BaMV resistance. The aba2-1 mutant decreased the accumulation of BaMV (+)RNA, (–)RNA, and coat protein, with the most dramatic effect being observed for (–)RNA. These findings were further validated by the use of virus-induced gene silencing and enzyme-linked immunosorbent assay in N. benthamiana. In addition, infecting N. benthamiana with BaMV or CMV increased ABA contents and activated the SA and ABA pathways, thereby disrupting the antagonism between these two cascades. Our findings uncover a novel role for ABA2 in supporting BaMV and CMV accumulation, distinct from the opposing role of its downstream genes.
