Interactions of PatA with the Divisome during Heterocyst Differentiation in
mSphere, 2020 The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric N2 and provide the vegetative ...

Sustaining Rice Production through Biofertilization with N2-Fixing Cyanobacteria
Applied Sciences, 2021 Current agricultural productivity depends on an exogenous nutrient supply to crops. This is of special relevance in cereal production, a fundamental part of the trophic chain that plays a vital role in the human diet.

DNA methylation at tobacco telomeric sequences [PDF]
, 2011 Majerová et al. (Plant Mol Biol, 2011) have recently reported that a considerable fraction of cytosines at tobacco telomeres is methylated. Although the data presented in this report indicate that tobacco telomeric sequences undergo certain levels of DNA

Plants maximise chloride uptake during early vegetative development to stimulate cell expansion, maturation of the photosynthetic apparatus, and growth. [PDF]
Plant JSUMMARY Despite being an essential micronutrient and its recent classification as a beneficial macronutrient, chloride (Cl−) has traditionally been considered of limited agricultural relevance and a potentially toxic saline ion. This study provides the first comprehensive demonstration of the quantitative and qualitative importance of Cl− during early ...

Glutaredoxins are essential for stress adaptation in the cyanobacterium Synechocystis sp. PCC 6803.
Frontiers in Plant Science, 2013 Glutaredoxin are small redox proteins able to reduce disulfides and mixed disulfides between GSH and proteins. Synechocystis sp. PCC 6803 contains three genes coding for glutaredoxins: ssr2061 (grxA) and slr1562 (grxB) code for dithiolic glutaredoxins ...
