Transgenic Cavendish bananas with resistance to Fusarium wilt

Banana, the common breakfast component, is also a staple food in some regions of the world. More than 99% of the bananas exported world-wide are the clonally-propagated Cavendish variety, which have very little genetic variation and so are prone to disease outbreaks. Recent years have witnessed the emergence of a fungus that has threatened Cavendish […]

Laccaria bicolor MiSSP8 is a small-secreted protein decisive for the establishment of the ectomycorrhizal symbiosis

Mycorrhizal symbiosis involves extensive signaling between plants and their fungal partners. Mycorrhiza-induced small secreted proteins (MiSSPs) have been hypothesized to be involved in diverse processes to suppress plant defense and promote fungal life-cycles. Clement et al. functionally characterized a highly expressed small secreted protein MiSSP8 from Laccaria bicolor, and showed that it helps establish ectomycorrhizal […]

Ecosystem responses to elevated CO2 are governed by plant-soil interactions and the cost of nitrogen acquisition

How does the cost of nitrogen acquisition affect how an ecosystem responds to elevated CO2? Terrer et al. have addressed this question in a comprehensive review of findings from elevated CO2 experiments, using a plant economics framework. The authors describe ecosystem responses, particularly those of plants to elevated CO2, by interactions with mycorrhizal fungi and […]

Review: Autophagy as a mediator of life and death in plants ($)

Autophagy is a major pathway involved in degradation and recycling of the cytoplasmic components in a cell. This pathway is functionally well conserved in maintaining cellular homeostasis and modulation of stress responses among yeast, plants and animals. Recent evidence suggests that autophagy targets a range of components in cell machinery. In plants, the role of […]

Roots-eye view: Using microdialysis and microCT to non-destructively map root nutrient depletion and accumulation zones

Plant roots constantly engage in nutrient and water uptake for crop productivity. Increasing the nutrient uptake efficiency of roots will promote sustainable agriculture by decreasing the need for fertilizer applications. To achieve this task, we need to understand the physiology of intact roots in their natural soil environment. Brackin et al. examined root nutrient foraging […]

Deep learning for multi-task plant phenotyping

Despite the significant developments in computational biology and modern plant breeding, crop phenotyping poses challenges for automation. Previous machine learning approaches of plant phenotyping have mainly focused on leaf counting in rosette forms or leaf segmentation, and rely on large datasets not particularly useful for monocot crops. Pound et al. have recently described a valuable […]

PLETHORA transcription factors orchestrate de novo organ patterning during Arabidopsis lateral root outgrowth

Lateral root development in plants is a complex process that involves co-ordination of several molecular components to initiate the formation of meristematic cells. Uncovering the details of these processes is confounded by functional redundancy and tight cyclic regulation of different components in the process. Du and Scheres have recently beautifully elucidated these sequential phenomenon and […]

Signatures of adaptation to mutualists revealed by root transcriptional dynamics

A plant’s rhizosphere consists of a huge array of pathogenic microbes many of which can trigger defense responses, leading to decreased growth. On the other hand, beneficial microbes such as rhizobacteria promote growth and can induce systemic resistance while suppressing local immune responses. A recent study aimed to understand the differential host responses towards the […]
