🌱🧬 Plants sense uneven soil nutrients and remodel roots accordingly. Nitrate foraging involves local sensors, systemic signals, and shoot-root coordination.

Understanding this could improve nitrogen use efficiency in crops. #plantscience @jipb.bsky.social

Final corrected proof now online in @jxbotany.bsky.social
Curious about phloem, grafting, starch, source–sink relations, or plant growth? Using phloem development mutants and grafting, we show that root phloem is key for coordinating both root and shoot growth.

Proper root phloem differentiation is essential for carbon partitioning and systemic growth coordination. Even mild root phloem defects impair root and shoot performance, underscoring sink phloem development as critical for optimizing source–sink balance - Bartusch et al.
Fig. 5 (shortened, full legend in paper): Correlation of primary root length with protophloem defect frequency. (A) Primary root length of 8-day-old ops and ops opl2 plants was classified as ‘long’ or ‘short’ (see Supplementary Fig. S5) and compared with the wild type (WT). Individual data points are shown for all datasets, complemented by boxplots indicating the 25th, 50th (median), and 75th percentiles, with whiskers representing ±1.5 times the interquartile range. Data were analysed using the Kruskal–Wallis test followed by Dunn’s post-hoc test with Benjamini–Yekutieli correction. (B) Protophloem defect frequency using three categories: (i) neither protophloem strand shows gaps in a given root; (ii) one protophloem strand has gaps while the other is intact; and (iii) both protophloem strands have gaps in the same root.

🌱🧬 Root phloem defects stay in the root. But those defective roots send feedback that restricts shoot growth too.

🌱From eLife:Salt stress disrupts root–shoot coordination in Arabidopsis, revealing SR3G as a key gene that limits suberization and resilience. New tools uncover how plants manage ion balance and growth under stress.(Minmin Wang, Georgia Drakakaki)

#PlantScience
Figure 1.. Salt stress is causing discoordination of root and shoot growth. Arabidopsis HapMap population was screened for salt stress-induced changes in root:shoot ratio. The increase in the projected area of shoot and root (Figure 1—figure supplement 2) was used to estimate (A) shoot and (B) root exponential growth rate. (C) The root:shoot growth rate ratio was calculated per genotype. The histograms represent the number of accessions across three studied conditions (0, 75, and 125 mM NaCl), whereas the population average is indicated using the dashed line. Additionally, the distribution of the genotypes within each treatment was visualized using the error plots (lower panel), where population average and standard error is indicated using a colored point and a line, respectively. Individual gray points represent individual genotypes.
