Proton relaxometry of tree leaves at hypogeomagnetic fields Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Anne M. Fabricant, Piotr Put, Danila A. Barskiy
We report on a cross-species proton-relaxometry study in ex vivo tree leaves using nuclear magnetic resonance (NMR) at 7µT. Apart from the intrinsic interest of probing nuclear-spin relaxation in biological tissues at magnetic fields below Earth field, our setup enables comparative analysis of plant water dynamics without the use of expensive commercial spectrometers. In this work, we focus on leaves

Climatic and biogeographic processes underlying the diversification of the pantropical flowering plant family Annonaceae Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Weixi Li, Runxi Wang, Ming-Fai Liu, Ryan A. Folk, Bine Xue, Richard M. K. Saunders
Tropical forests harbor the richest biodiversity among terrestrial ecosystems, but few studies have addressed the underlying processes of species diversification in these ecosystems. We use the pantropical flowering plant family Annonaceae as a study system to investigate how climate and biogeographic events contribute to diversification. A super-matrix phylogeny comprising 835 taxa (34% of Annonaceae

Ambient temperature regulates root circumnutation in rice through the ethylene pathway: transcriptome analysis reveals key genes involved Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Zeping Cai, Yinuo Dai, Xia Jin, Hui Xu, Zhen Huang, Zhenyu Xie, Xudong Yu, Jiajia Luo
Plant roots are constantly prepared to adjust their growth trajectories to avoid unfavorable environments, and their ability to reorient is particularly crucial for survival. Under laboratory conditions, this continuous reorientation of the root tip is manifested as coiling or waving, which we refer to as root circumnutation. However, the effect of ambient temperature (AT) on root circumnutation remains

Aphid gene expression following polerovirus acquisition is host species dependent Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Sudeep Pandey, Michael Catto, Phillip Roberts, Sudeep Bag, Alana L. Jacobson, Rajagopalbabu Srinivasan
Upon acquisition of persistent circulative viruses such as poleroviruses, the virus particles transcytose through membrane barriers of aphids at the midgut and salivary glands via hemolymph. Such intricate interactions can influence aphid behavior and fitness and induce associated gene expression in viruliferous aphids. Differential gene expression can be evaluated by omics approaches such as transcriptomics

Comparison of the sugar and organic acid components of seventeen table grape varieties produced in Ankara (Türkiye): a study over two consecutive seasons Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Birhan Kunter, Osman Batur Unal, Sıddık Keskin, Harlene Hatterman-Valenti, Ozkan Kaya
Sugars and organic acids not only have a significant impact on taste balance and sensory acceptance by consumers but also play a crucial role in the chemical equilibrium of grape juices and wines. Therefore, this study aimed to quantify the content and composition of sugars and organic acids in 17 grape varieties over two consecutive years using high-performance liquid chromatography. The variability

The effect of marker types and density on genomic prediction and GWAS of key performance traits in tetraploid potato Front. Plant Sci. (IF 5.6) Pub Date : 2024-03-08 Trine Aalborg, Elsa Sverrisdóttir, Heidi Thorgaard Kristensen, Kåre Lehmann Nielsen
Genomic prediction and genome-wide association studies are becoming widely employed in potato key performance trait QTL identifications and to support potato breeding using genomic selection. Elite cultivars are tetraploid and highly heterozygous but also share many common ancestors and generation-spanning inbreeding events, resulting from the clonal propagation of potatoes through seed potatoes. Consequentially
