Welcome to the Journal of Experimental Botany editorial page!
JXB aims to publish high quality manuscripts that provide substantial new insights of broad interest in plant biology. We welcome manuscripts that identify fundamental mechanisms including those underpinning the improvements of plant for the sustainable production of food, fuel, and renewable materials. Our emphasis is on molecular physiology, molecular genetics, and environmental physiology, and we also encourage integrative approaches employing cutting-edge technologies, systems biology, and synthetic biology.

Coming soon:Photo-oxidative stress in emerging and senescing leaves: a mirror image? M Juvany, M Müller, and S Munné-Bosch This review focuses on the role of photo-oxidative stress both at early stages of leaf growth and during leaf senescence. We consider early leaf growth to be the stages at which the leaf is photosynthetically active but still depends on imported photoassimilates for net growth. During leaf senescence, we focus on the processes involved in the initiation, re-organization and terminal phases. Furthermore, we aim at characterizing such processes beyond the information gathered in the model plant Arabidopsis thaliana and include recent literature on the topic obtained in perennials. Shrinking the hammer: micromechanical approaches to morphogenesis P Milani, SA Braybrook & A Boudaoud Shape is imposed by the structural elements of the organism, and the translation of cellular activity into morphogenesis must go through these elements. Many methods have been recently developed to quantify at cellular resolution the properties of the main structural element in plants, the cell wall. As plant cell growth is restrained by the cell wall and powered by turgor pressure. These different micromechanical approaches are reviewed here, with a critical assessment of their strengths and weaknesses, and a discussion of how they can help us understand the regulation of growth and morphogenesis. On the role of stress anisotropy in the growth of stems TI Baskin & OE Jensen Efforts to quantify stress anisotropy in the stem have found that it is predominantly axial, and large enough in principle to explain the elongation of the epidermis despite its axial microfibrils. That the epidermis experiences a stress deriving from the inner tissue, the so-called “tissue stress”, has been widely recognized; however, the origin of the dominant axial direction remains obscure. We suggest that understanding the role of stress anisotropy in plant growth requires a deeper understanding of the nature of stress in hierarchical, organic structures. Emerging roles of microRNAs in the mediation of drought stress response in plants Y Ding, Y Tao, and C Zhu Drought is a major environmental stress factor that limits agricultural production worldwide. This review summarizes recent molecular studies on the miRNAs involved in the regulation of drought-responsive genes, with emphasis on miRNA-associated regulatory networks involved in drought stress response. Lateral root initiation is a probabilistic event whose frequency is set by fluctuating levels of auxin response MJ Laskoswski This review assesses the sequence of molecular events that lead to lateral root formation in relation to the locations in which they occur, addresses how nutrients regulate the response generally though not exclusively by altering sensitivity to auxin, and finally considers the factors that control auxin levels. Evidence of oxidative attenuation of auxin signalling WA Peer, Y Chen & AS Murphy This report summarizes previously published data and show additional data regarding oxIAA is generation in planta, oxIAA as a substrate in transport assays, and oxIAA as a signalling molecule in auxin-mediate responses. It then examine the relationship between IAA and ROS generation, and oxIAA levels in ROS scavenging mutants. The role of auxin in shaping shoot architecture A Gallavotti Recent advances in deciphering the molecular mechanisms that regulate auxin function have produced several tools to investigate how auxin affects the establishment and plasticity of plant morphology. Here the extensive evidence that connects auxin and its biology with the determination of plant shoot architecture is reviewed, with particular emphasis on the most recent discoveries in two well-studied model plant systems, the dicotyledonous Arabidopsis and the monocot maize. Tuning the auxin transcriptional response Pierre-Jerome, Moss & Nemhauser How does auxin provoke such a diverse array of responses? We review what is currently known about differences between family members of the components that make up the auxin response complex, as well as areas of potential differences in their interactions outside of the core module

Advance Access: Review papersAuxin - simply complicated M Sauer, S Robert, & J Kleine-Vehn Auxin is a plant hormone involved in an extraordinarily broad variety of biological mechanisms. These range from basic cellular processes, such as endocytosis, cell polarity and cell cycle control over localized responses like cell elongation and differential growth, to macroscopic phenomena such as embryogenesis, tissue patterning and de novo formation of organs. This review gives an overview of these rather recent and emerging areas of auxin research, and tries to formulate some of the open questions. The solar rhythm in the regulation of photoperiodic flowering of long-day and short-day plants Hoong-Yeet Yeang This report proposes a role of the plant's solar rhythm in promoting seasonal flowering. The interaction between rhythmic genes entrained to the solar clock and those entrained to the circadian clock form the basis of an Internal Coincidence model that explains both long day and short day flowering equally well. Thermography to explore plant-environment interactions Costa et al. This review presents and discusses the advantages of thermal imaging applications to plant science, agriculture, and ecology, as well as its limitations and possible approaches to minimize them, by highlighting examples from previous and ongoing research. Auxin biosynthesis and storage forms DA Korasick, TA Enders, and LC Strader We discuss the many ways auxin levels are regulated through biosynthesis, storage forms, and inactivation and the potential roles modified auxins play in regulating the bioactive pool of auxin to affect plant growth and development Auxin and the Arabidopsis thaliana gynoecium E Larsson, RG Franks & E Sundberg This review summarizes recent advances in our understanding of how auxin biosynthesis, transport and responses together generate specific gynoecial domains. We also highlight areas where future research endeavors are likely to provide additional insight into the homeostatic molecular mechanisms by which auxin regulates gynoecium development Auxin and self-organization at the shoot apical meristem Sassi and Vernoux This review discusses both the experimental and theoretical evidence for the implication of auxin in the control of organogenesis and self organization of the shoot apical meristem. Will C3 crops enhanced with the C4-CCM live up to their full potential (yield)? Driever & Kromdijk In this review, we assess possible positive or negative effects of the introduction of a carbon concentrating mechanism in C3 crop species on crop potential productivity and yield robustness. Measurement of the matric potential of soil water in the rhizosphere Whalley, Ober & Jenkins
In this review, the relationship between matric potential and soil water content is explored. It is shown that for any given soil type, this relationship is not unique and therefore both soil water content and matric potential need to be measured for the soil water status to be fully described.
