Chloroplasts navigate towards the pathogen interface to counteract Phytophthora infection (bioRxiv)

/in /by

Chloroplasts have diverse roles in plant defense, including contributing to the production of defense compounds. Toufexi, Duggan et al. show new data indicating the dynamic relocation of chloroplasts to the contact point of the oomycete pathogen Phytophthora infestans. Infection also causes an increase of stromule formation (stromules are chloroplast membrane extensions implicated in defense). The […]

Root branching toward water involves posttranslational modification of transcription factor ARF7 ($) (Science)

/in /by

Roots do amazing things, particularly in terms of how they optimize their growth in response to their very local environment including water, nutrients, microbes, and physical obstructions. Branching in regions of contact with water is called hydropatterning, and previous studies showed that an auxin gradient forms in response to differential water contact.

Review: Computational approaches to design and test plant synthetic metabolic pathways (Plant Physiol)

/in /by

As photosynthetic organisms, plants are desirable and potentially cost-effective chassis for the production of novel compounds, but they are also inherently metabolically complex. Synthetic metabolic pathways can also improve upon nature by making plants more metabolically efficient. Küken and Nikoloski review methods to design novel synthetic metabolic pathways for expression in plants. As the authors […]

Genome-scale fluxome of Synechococcus elongatus UTEX 2973 using transient 13C-labeling data (Plant Physiol)

/in /by

Synechococcus elongates UTEX 2973 (also known as Synechococcus 2973) has the fastest doubling time of known cyanobacteria, completely replicating itself in just over two hours. This fast growth rate makes it an interesting platform for industrial applications. Hendry et al set out to understand what makes it so fast, using genome-scale Isotopic Non-Stationary-13C-Metabolic Flux Analysis […]

The mechanism by which MYC2 regulates the termination of jasmonic acid signaling

/in , /by

Source: Institute of Genetics and Developmental Biology Published: 2019-01-11. Translated from the original. As an important plant hormone, jasmonic acid regulates plant defense responses and adaptive growth. When the plant is exposed to pests or other stresses, the active jasmonic acid is recognized by the receptor COI1 (CORONATINE-INSENSITIVE 1) to release the activity of the […]
