🆕 The new issue of @annbot.bsky.social is now online!

🌸 Reproduction, pollination & mating systems
🧬 Genomics, evolution & sex chromosomes
🌍 Climate, drought & stress
🌳 Structure & 3-D plant architecture
📚 Botanical education & science communication

New issue👉https://botany.fyi/zpnizz
The front cover shows Gladiolus carneus, different ecotypes of which occupy diverse pollination niches and, in turn, contribute to pollinator-mediated isolation. Here, the long-tongued fly, Philoliche rostrata, can be seen visiting the high-elevation ecotype on the top of Jonaskop in the Cape Floristic Region of South Africa.

Tree age affects key fine root morphological traits but does not interfere strongly with (ecto-)mycorrhizal traits by Yu Qin and co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj59

#RootBiology #PlantStress #RootPhysiology #PlantScience
As trees grow older, they adjust how their roots explore the soil, shifting toward more efficient resource uptake, while their dependence on fungal partners remains largely unchanged. This shows that root strategies change naturally with age and that trees in mixed-age forests respond differently than those growing in uniform stands.

Two grasses differ in their absorptive root physiological traits and rooting depth under drought in an alpine steppe by Zhi Zheng and co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj6f

#RootBiology #RootPhysiology #PlantScience
In alpine grasslands, drought-driven shifts in species dominance are governed less by root form than by root function, with species that reallocate carbon from respiration to exudation and deeper rooting gaining a competitive advantage in water and nutrient acquisition under prolonged drought.

Enhanced lignin and cellulose metabolism promote cell wall synthesis and growth of wild soybean HRA under alkali stress by Yunan Hu and co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj6d

#RootBiology #RootPhysiology #PlantScience
Wild soybean withstands alkali stress during early establishment by rapidly mobilizing cotyledon reserves and reinforcing hypocotyl–root axis cell walls, revealing stress-resilient traits absent in cultivated soybean that could be utilized to improve crop performance on saline–alkaline soils.

The role of aerenchymatous gas spaces in root sodium ion management under salt stress: do they matter in rice? by Subhankar Mondal and co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj6c

#RootBiology #RootPhysiology #PlantScience
Salt-tolerant rice genotypes respond to salinity by increasing root porosity and aerenchyma formation via programmed cell death, a root trait tightly linked to limiting Na⁺ transport to shoots while retaining K⁺—highlighting root tissue architecture as a key, selectable target for improving salt tolerance in rice.

#RootBiology #RootPhysiology #PlantScience
CLV3/EMBRYO-SURROUNDING REGION peptide signalling in legumes links plant development and environmental responses, with pea studies revealing that different CLE receptors play distinct and sometimes opposing roles in controlling shoot growth, especially under cool conditions, highlighting both conserved and flexible functions of this pathway beyond symbiosis.

Leaf manganese concentrations reveal phosphorus-mining strategies and trait diversification of Myrtaceae in south-eastern Australia by Li Yan and co-authors in @annbot.bsky.social

@westsyduhie.bsky.social

Myrtaceae challenge the traditional mycorrhizal–non-mycorrhizal divide by using carboxylate-driven phosphorus mining despite fungal associations, revealing convergent evolution of P-acquisition strategies that helps explain their dominance and diversification in phosphorus-impoverished ecosystems.

#PlantScience
Differences in root traits among species are shaped mainly by the environments they are adapted to, especially levels of soil disturbance, rather than by lifespan or evolutionary history, with root form showing consistent patterns across environments while root chemistry and biomass allocation are more context dependent.

Temperature and plant-available soil phosphorus drive intraspecific variation in plant economic traits of Schima superba across an elevation gradient by Jinlong Li by Zhiwei Song co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj55
Within a single tree species, leaf and root traits remain tightly coordinated across environmental gradients, forming an intraspecific whole-plant economics spectrum driven primarily by temperature and soil phosphorus rather than decoupling between above- and below-ground strategies.

Rice cycles between drought and well-watered-adapted phenotypes by changing lateral root formation by Helena Bochmann co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qj56

#RootBiology #PlantStress #RootPhysiology #PlantScience
This study shows that drought recovery in rice is strongly linked to root traits established before stress: genotypes with more thick lateral roots experience fewer structural changes during drought–re-wetting cycles and recover more effectively. ‘ARC 18202’ exemplifies this strategy and represents a promising resource for breeding drought-resilient rice.

Anatomical and physiological responses of roots and rhizomes in Oryza longistaminata to soil water gradients by Zhiwei Song co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qjt3

#RootBiology #PlantStress #RootPhysiology #PlantScience
Oryza longistaminata uses its interconnected rhizomes to buffer water-deficit stress between mother plants and ramets, while both roots and rhizomes adjust their anatomy to cope with drought and flooding, highlighting its strong potential for breeding resilient perennial rice.

Root morphology and anatomy respond similarly to drought and flooding in two wheat cultivars by Tobias Guhr co-authors in @annbot.bsky.social

#freeaccess article
👉 doi.org/qjt2

#RootBiology #PlantStress #RootPhysiology #PlantScience
This study reveals that drought and flooding trigger surprisingly parallel root responses in wheat, including increased aerenchyma formation and reinforced endodermal barriers. Because these contrasting stresses converge on similar root strategies, targeting these common traits could help breeders develop varieties that cope better with both extremes.
