Game changer for cell-based plant genetics: the labs of Caixia Gao & Jin-Long Qiu have developed very efficient self-replicating vectors and they just published a very nice proof-of-concept paper.

Box 1. Key developments in understanding FtsH functions for organelle protein homeostasis in Arabidopsis The schematic illustration shows the primary and 3D structure of FtsH (A–C) and highlights recent advances in understanding the roles of plant FtsHs localized in chloroplasts (D, E, and H) and mitochondria (F and G). See paper for full description of Box 1.

📖 SPECIAL ISSUE REVIEW 📖

In this review, Wang et al. describe the protease, chaperone-like, and substrate processing working modes of plant FtsH, and summarize the role of FtsH in organelle protein homeostasis 🔄 🌱

A plant virus causes symptoms through the deployment of a host-mimicking protein domain to attract the insect vector Plant viruses cause symptoms with devastating consequences for agriculture. However, the molecular mechanisms underlying symptom development in viral …

How do plant viruses cause symptoms? Are these developmental alterations functionally relevant? Man Gao, Enmanuel, et al. found that TYLCV does so through a host-mimicking domain in its C4 protein, co-opting a plant protein family - to attract the insect vector! www.sciencedirect.com/science/arti...

Sharma et al Figure 1 legend (shortened): Hormones mediate root responses to water availability. (A) Under homogeneous water distribution in soil, lateral roots (LRs) develop symmetrically, resulting in a uniform root system. (B) Root tips show hydrotropism and bend towards areas with high water potential. (C) Growing root tips pause branching in air gaps (xerobranching). (D) Asymmetric SUMOylation of the auxin response factor ARF7 induces asymmetric distribution of lateral roots, leading to hydropatterning. Ethylene suppresses LR formation on the air side of the root. (E) Soil drying decreases water potential vertically, promoting steeper root growth or xerotropism by the action of Deeper Rooting 1 (DRO1). Auxin negatively regulates DRO1, triggering downward bending. Water availability is represented as a blue colour gradient.
