Nature. Cuscuta sp. commonly known as dodder, is an obligate parasitic plant that colonizes a broad range of host plants and obtain water and nutrients by specialized feeding structure called haustorium.  Literature suggests that this specialized structure is involved in bidirectional movement of viruses,…

Schmitz et al. investigate the physiological significance of the glyoxylase system  in Arabidopsis https://doi.org/10.1105/tpc.17.00258 By Jessica Schmitz and Veronica G. Maurino BACKGROUND: In every living cell, side reactions of enzymes and spontaneous reactions of metabolites inevitably…

Regulation of transcription occurs at the cell-type specific level, but transcribed messenger RNA is mobile and can move between tissues through plant vasculature, serving as a long distance messenger. Many mRNA molecules have been identified in the phloem sap, suggesting that mRNA transport goes through…

Phytochromes are photoreceptors found in many organisms including bacteria, fungi and plants. Plant phytochromes regulate many aspects of plant growth and development, including germination, shade avoidance, defense against pests, and senescence. Phytochromes most likely transduce signals through the…

Wang et al. discover unexpected connections between humidity and ion transport using a model that bridges guard cell-to-leaf scales https://doi.org/10.1105/tpc.17.00694 By Maria Papanatsiou Background: Plants rely on stomata on the leaf epidermis for their survival. Stomata are small pores formed…

Brambilla et al. describe antagonistic signals in rice leaves that control flowering https://doi.org/10.1105/tpc.17.00645 By Vittoria Brambilla Background: A plant’s lifecycle is marked by a major switch occurring when the plant stops producing leaves and starts to make flowers. This switch is…

Broad-Spectrum Disease Resistance in Tomato Zhu et al. examine how a plant receptor protein confers broad-spectrum resistance to various tospovirus pathogens https://doi.org/10.1105/tpc.17.00180 By Min Zhu, Savithramma P. Dinesh-Kumar, and Xiaorong Tao Background: Highly evolved microbes cause…

Plants are highly plastic and can modulate their growth and development to better respond to abiotic and biotic surroundings. Among the molecules involved in the adaptation to the environment, a crucial role is played by small secreted peptides (SSPs). In their paper, integrating 144 transcriptomic experiments,…
