    Abstract In response to unilateral blue light illumination, roots of some plant species such as Arabidopsis thaliana exhibit negative phototropism (bending away from light), which is important for light avoidance in nature. MIZU-KUSSEI1 (MIZ1) and GNOM/MIZ2 are essential for positive hydrotropism (i.e. in the presence of a moisture gradient, root bending towards greater water availability). Intriguingly, mutations in these genes also cause a substantial reduction in phototropism. Here, we examined whether the same tissue-specific sites of expression required for MIZ1- and GNOM/MIZ2-regulated hydrotropism in Arabidopsis roots are also required for phototropism. The attenuated phototropic response of miz1 roots was completely restored when a functional MIZ1–green fluorescent protein (GFP) fusion was expressed in the cortex of the root elongation zone but not in other tissues such as root cap, meristem, epidermis, or endodermis. The hydrotropic defect and reduced phototropism of miz2 roots were restored by GNOM/MIZ2 expression in either the epidermis, cortex, or stele, but not in the root cap or endodermis. Thus, the sites in root tissues that are involved in the regulation of MIZ1- and GNOM/MIZ2-dependent hydrotropism also regulate phototropism. These results suggest that MIZ1- and GNOM/MIZ2-mediated pathways are, at least in part, shared by hydrotropic and phototropic responses in Arabidopsis roots.

    Sensitivity to ultraviolet-B (UVB, 280–315 nm) radiation varies widely among rice (Oryza sativa) cultivars due to differences in the activity of cyclobutane pyrimidines dimer (CPD) photolyase. Interestingly, cultivars with high UVB sensitivity and low CPD photolyase activity have been domesticated in tropical areas with high UVB radiation. Here, we investigated how differences in CPD photolyase activity affect plant resistance to the rice blast fungus, Magnaporthe oryzae, which is one of the other major stresses. We used Asian and African rice cultivars and transgenic lines with different CPD photolyase activities to evaluate the interaction effects of CPD photolyase activity on resistance to M. oryzae. In UVB-resistant rice plants overexpressing CPD photolyase, 12 h of low-dose UVB (0.4 W m−2) pretreatment enhanced sensitivity to M. oryzae. In contrast, UVB-sensitive rice (transgenic rice with antisense CPD photolyase, A-S; and rice cultivars with low CPD photolyase activity) showed resistance to M. oryzae. Several defense-related genes were upregulated in UVB-sensitive rice compared to UVB-resistant rice. UVB-pretreated A-S plants showed decreased multicellular infection and robust accumulation of reactive oxygen species. High UVB-induced CPD accumulation promoted defense responses and cross-protection mechanisms against rice blast disease. This may indicate a trade-off between high UVB sensitivity and biotic stress tolerance in tropical rice cultivars. Graphical Abstract: [Figure not available: see fulltext.].

    Abstract Root gravitropism affects root hydrotropism. The interference intensity of root gravitropism with root hydrotropism differs among plant species. However, these differences have not been well compared within a single plant species. In this study, we compared root hydrotropism in various natural variants of Arabidopsis under stationary conditions. As a result, we detected a range of root hydrotropism under stationary conditions among natural Arabidopsis variants. Comparison of root gravitropism and root hydrotropism among several Arabidopsis natural variants classified natural variants that decreased root hydrotropism into two types; namely one type that expresses root gravitropism and root hydrotropism weaker than Col-0, and the other type that expresses weaker root hydrotropism than Col-0 but expresses similar root gravitropism with Col-0. However, root hydrotropism of all examined Arabidopsis natural variants was facilitated by clinorotation. These results suggested that the interference of root gravitropism with root hydrotropism is conserved among Arabidopsis natural variants, although the intensity of root gravitropism interference with root hydrotropism differs.

    Green plants produce carbohydrate as an energy for all organisms by photosynthesis. It is therefore considered that plant cultivation is necessary for life support not only on Earth but also in space. To inhabit the space for a long duration, human needs to be closed in the life support system in which plants provide them with foods and a stress-relief circumstance. During evolution, on the other hand, plants developed various strategies to survive terrestrial environment on Earth because of their sessile nature. Plant responses to gravity and lights are examples of such strategy to avoid or mitigate stressful environment they come across. Now, space environment is available for biological studies to understand how plants respond to gravity and how plants are influenced by microgravity and/or space radiation. We extend such studies to understand the effects of space environment on plant growth and development in the seed-to-seed or the generation-to-generation experiments. To explore the deeper space or inhabit planets such as the moon or Mars, we next need to establish a sustainable recycling-oriented life support system with plant cultivation and environmental control facilities. Here, we show our research scenario of the space-utilizing plant science to achieve such objective, which is important to efficiently cultivate plants and develop the life support system in space. We believe our approach, in cooperation with various communities of the related fields, enables us to further reveal the biological systems required for not only colonizing to space but also conserving or improving the living Earth.

    植物は重力をシグナルとして利用し、とくに陸地環境における生存に必要な形態、姿勢、伸長方向の制御を可能にした。この植物の重力応答（受容）の仕組みを理解することは、生物学的課題であるだけでなく、人類の生命維持システムの保持および宇宙への生命圏の拡大のために、エネルギー源と環境を確保するという観点から極めて重要である。本研究班ワーキンググループ(WG)では、このような生物進化、地球環境、生命維持システム、有人宇宙活動、いずれの観点からもフロンティアの先端に立つ植物の生活を支える「重力受容システム」の解明に向けて、研究の現状と課題を整理し、地上研究に基づいて得られる仮説を検証すべく宇宙実験系を確立することを目的としている。
