Abstract ：
Intracellular Ca2+ controls various cellular functions and local Ca2+ dynamics are tightly regulated upon environmental cues. Maintaining cellular Ca2+ balance is essential for plant survival. Here we report a calcium-dependent protein kinases (CPKs)-mediated signaling pathway, in conjunction with the ER membrane-resident Ca2+-ATPase ECA1, acts influentially for cytosolic Ca2+ homeostasis and osmotic stress tolerance. We show that targeting cytosolic Ca2+ efflux via specific inhibitors or eca1 mutation results in augmented [Ca2+]cyt spikes, elevated cytoplasmic ABA ([ABA]cyt) level and ultimately hypersensitive to osmotic stress. Screening of Arabidopsis CPKs revealed direct binding of CPK2/6/11 to ECA1. Moreover, CPK2/6/11 phosphorylates the N-terminal of ECA1 at Ser5, thereby enhancing its activity for cytosolic Ca2+ efflux into ER and subsequently lowering [ABA]cyt. The cumulative effect of ECA1 and CPKs mutation on Arabidopsis plant sensitivity to osmotic stress further illustrates that CPKs/ECA1 acts as an intracellular module for tuning stress response via regulating [Ca2+]cyt and [ABA]cyt homeostasis. © 2025, The Authors.

Abstract ：
White lupin (Lupinus albus L.) produces cluster roots to acquire more phosphorus under phosphorus deficiency. Bacillus amyloliquefaciens SQR9 contributes to plant growth, but whether and how it promotes cluster root formation in white lupin remain unclear. Here, we investigated the roles of SQR9 in cluster root formation under low phosphorus conditions using a microbial mutant and virus-induced gene silencing (VIGS) in white lupin. SQR9 substantially enhanced cluster root formation under low phosphorus conditions. The ysnE gene encodes an auxin biosynthesis enzyme in SQR9 and was associated with cluster root formation, as ysnE-defective SQR9 did not trigger cluster root formation. SQR9 inoculation induced the expression of PIN-formed2 (LaPIN2, encoding an auxin transporter) and YUCCA4 (LaYUC4, encoding an auxin biosynthesis enzyme) in white lupin roots. VIGS-mediated knockdown of LaPIN2 and LaYUC4 prevented wild-type SQR9-induced cluster root formation in white lupin. Finally, white lupin LaYUC4-derived auxin and SQR9-derived auxin pools were both transported by LaPIN2, promoting cluster root formation under low phosphorus conditions. Taken together, we propose that B. amyloliquefaciens promotes cluster root formation in white lupin under low phosphorus conditions by stimulating auxin biosynthesis and transport. Our results provide insights into the interplay between bacteria and root auxin in crop phosphorus use efficiency. Bacillus amyloliquefaciens produces auxin and promotes auxin biosynthesis in white lupin under low phosphorus conditions, triggering cluster root formation.

Abstract ：
Rhizosheath formation-the adhesion of soil particles to root surfaces-has gained attention in sustainable agriculture due to its diverse contributions to plant health and productivity. This process is driven by root hairs, root exudates, and rhizosheath-associated microbial communities and shaped by plant genetics, and soil physical and chemical properties. Despite recent advances, the mechanisms underlying root-soil-microbe interactions remain poorly understood, especially in intercropping systems. Intercropping can alter belowground traits such as root system architecture, exudate profiles, and rhizosheath microbial communities, but direct links between these changes and rhizosheath formation remain unclear. We advocate incorporating rhizosheath-related traits into intercropping design to enhance crop resilience and productivity. This commentary highlights key research gaps, outlines future directions, and discusses applied perspectives for agronomy and breeding. Advancing rhizosheath biology could translate fundamental knowledge into practical innovations for sustainable agriculture.
