Review
Post-translational attachment of small ubiquitin-like modifier (SUMO), defined as SUMOylation, has emerged as a new mechanism of protein regulation in plant biology. In plant, SUMOylation has been shown to play crucial roles in a variety of biotic and abiotic stress responses. Recent work using viable mutants with defective SUMOylation have indicated an important role for SUMOylation in a wide range of developmental processes, such as cell division, expansion, survival and differentiation, vegetative growth and reproductive development. This review will summarize the currently emerging information regarding the function of SUMOylation in plant development.

Recent findings expanded our knowledge about plant redox regulation in stress responses by demonstrating that redox processes exert crucial nuclear regulatory functions in meristems and other developmental processes. Analyses of redox-modulated transcription factor functions and coregulatory ROXYs, CC-type land-plant specific glutaredoxins, reveal new insights into the redox control of plant transcription factors and participation of ROXYs in plant development. The role for ROS and redox signaling in response to low-oxygen conditions further strengthens the importance of redox processes in meristems and tissue differentiation as well as for adaptation to changing environments effecting food crop productivity.

Review
Despite their paramount role in plant life, the study of roots has been largely neglected until recently. Here, I shortly describe a few newly-discovered abilities of plants to undergo adaptive changes and execute developmental decisions based on roots' perception of non-resource information pertaining to imminent challenges and opportunities. Seemingly simple in their morphology and architecture and lacking central information-processing centres, roots are able to sense and integrate complex cues and signals over time and space that allow plants to perform elaborate behaviours analogous, some claim even homologous, to those of intelligent animals. Although our knowledge of root behaviour is rapidly expanding, further understanding of its underlying mechanisms is largely preliminary, calling for detailed investigation of the involved cues, signals and information processing controls, as well as their implications for plant development, growth and reproduction under realistic ecological and agricultural settings.

Review
Plant long noncoding RNAs (lncRNAs) play important roles in a wide range of biological processes, especially in plant reproductive development and response to stresses. They are transcribed by RNA polymerase II (Pol II), Pol III and Pol V, and exert their functions by a variety of regulation pathways. In this review, we summarized the current knowledge of lncRNAs discoveries in plant, including their identification, functions and regulation pathways as well as production and mediators, with an emphasizing on the novel regulation mechanisms in plant development.

Review
Nanomaterials, recently have found burgeoning attention in the field of agriculture, owing to the positive correlation between nanoparticle (NP) application and the enhanced nutritional status of the applied plants. A wide range of NPs, namely carbon-based NPs, titanium dioxide NPs, silica NPs etc. has been found to influence plants in a positive way by increasing their nutrient uptake ratio, nutrient usage efficiency, among others. All these attributes have paved the way for possible improvement in plant growth, development, vigour etc. through the use of these NPs, mainly as nanofertiliser. In view of all these, it can also be concluded that in the global scenario of increased demand of food production and supply in the coming years, nanotechnology promises to play a critical role. In this review, an attempt has been made to consolidate all the positive trends with respect to application of NPs on plants, along with their probable mechanism of action, which may provide a comprehensive insight for researchers working in this field.

Review
Both auxin signalling and programmed cell death (PCD) are essential components of a normally functioning plant. Auxin underpins plant growth and development, as well as regulating plant defences against environmental stresses. PCD, a genetically controlled pathway for selective elimination of redundant, damaged or infected cells, is also a key element of many developmental processes and stress response mechanisms in plants. An increasing body of evidence suggests that auxin signalling and PCD regulation are often connected. While generally auxin appears to suppress cell death, it has also been shown to promote PCD events, most likely via stimulation of ethylene biosynthesis. Intriguingly, certain cells undergoing PCD have also been suggested to control the distribution of auxin in plant tissues, by either releasing a burst of auxin or creating an anatomical barrier to auxin transport and distribution. These recent findings indicate novel roles of localized PCD events in the context of plant development such as control of root architecture, or tissue regeneration following injury, and suggest exciting possibilities for incorporation of this knowledge into crop improvement strategies.

Review
The definition of shape in multicellular organisms is a major issue of developmental biology. It is well established that morphogenesis relies on genetic regulation. However, cells, tissues, and organism behaviors are also bound by the laws of physics, which limit the range of possible deformations organisms can undergo but also define what organisms must do to achieve specific shapes. Besides experiments, theoretical models and numerical simulations of growing tissues are powerful tools to investigate the link between genetic regulation and mechanics. Here, we provide an overview of the main mechanical models of plant morphogenesis developed so far, from subcellular scales to whole tissues. The common concepts and discrepancies between the various models are discussed.

Review
Plants are sessile organisms and unlike animals, cannot run away from adverse environmental conditions. Therefore, they have evolved sophisticated signaling and protective systems to overcome sub-lethal stress situations. Although, effect of stress on physiology and morphology were studied earlier, the research on molecular mechanisms of stress response is albeit new. Studies at the molecular level on stress physiology reveal that, many stress-induced pathways converge downstream or interact significantly. Abiotic stress factors regulate the extent and pattern of developmental programme. The timing of transition from vegetative to flowering phase, which is vital for survival and reproductive success, is often altered under various stresses. Unraveling the mechanisms by which different environmental stresses induce their effects and how tolerance to stress is achieved is an active area of research. Enhancing stress tolerance, especially in crop plants is an area of prime importance. In this review, we focus on stress responses induced by temperatures, high and low light intensities, UV radiation, drought and salinity stress and summarize the recent advancements by highlighting the underlying molecular pathways and processes.
