Roots anchor plants and take up water, but one of their most important and complex functions is to bring a large number of different essential nutrients into the plant. Root architecture affects and is affected by nutrient uptake, but ultimately uptake is largely controlled by membrane-bound ion transporters.…

Plant Science Research Weekly: February 14 February 14, 2020/in Blog, WWR Full Post /by Mary Williams Review: Deep learning for plant genomics and crop improvement One of the goals of plant science is to use the molecular phenotype (genome, transcriptome, proteome) to predict the…

The well-known success of the green-revolution was accomplished through the development of semi-dwarf grasses (rice and wheat), which led to decreased losses to lodging and higher yields; however, the benefits of these improved varieties depends on the application of nitrogen-rich fertilizer. As N-rich…

Lateral roots arising from programmed cell division from primary roots in both monocots and dicots share some similarities and dissimilarities in developmental signaling. In this review, Waidmann et al. discuss lateral root organogenesis and elongation with respect to hormone, nutrient, and abiotic conditions.…

Iron (Fe) is an important micronutrient needed by plants for survival. Plants have evolved a range of morphological, physiological and molecular responses to Fe availability, including the transcriptional regulation of over one thousand genes in response to Fe deficiency (-Fe) in Arabidopsis. However,…

Nitrogen demands for plant growth are accomplished through fertilizers or biological nitrogen fixation. Industrial production of nitrogen fertilizer is expensive and causes pollution due to leaching of unused fertilizer. In this review, Bloch et al. discuss the current status of biological nitrogen fixation…

Nitrogen, as one of the most important plant nutrients, profoundly affects root growth. Nitrogen is usually taken up in one of two forms, nitrate (NO3-) or ammonium (NH4+), and the two forms affect root growth differently. Here, Jiao et al. demonstrate a connection between ammonium, a small RNA, and…

The pathogenic bacterium Ralstonia solanacearum enters roots through wounds and also at root tips. It can also infect legume nodules. Benezech et al. investigated how this infection occurs, and how it is affected by and affects nitrogen fixation. The authors found that nodules are as permissive of Ralstonia…
