Isopod feces–mediated shifts in germination timing enhance seedling establishment

New Phytologist, Volume 249, Issue 4, Page 1909-1919, February 2026.
Summary Seedlings are particularly vulnerable to herbivory because their defenses are underdeveloped and their capacity to tolerate damage is limited. However, how seedlings cope with such threats remains poorly understood. Animal feces may provide important chemical cues that influence plant responses to herbivory.

Discovery of Blue Hook Stars in the Massive Globular Cluster M54

, 2003
We present BV photometry centered on the globular cluster M54 (NGC 6715). The color-magnitude diagram clearly shows a blue horizontal branch extending anomalously beyond the zero age horizontal branch theoretical models.

Drying suppresses fine root production to 1 m depths and alters root traits in four distinct tropical forests

New Phytologist, Volume 249, Issue 4, Page 1992-2009, February 2026.
Summary Drying and drought in tropical forests, which have some of the highest net primary productivity on Earth, are likely to alter root dynamics, ecosystem function, and carbon (C) storage. We used a chronic drying experiment in four lowland Panamanian forests to investigate whether soil drying shifts tropical forest root production from surface to ...

Legacies of consecutive summer droughts on soil‐borne plant parasitic protists (Oomycota: Stramenopila and Phytomyxea: Rhizaria) and protistan consumers (Cercozoa: Rhizaria) along an experimental plant diversity gradient

New Phytologist, Volume 249, Issue 4, Page 2010-2024, February 2026.
Summary Increasing frequencies of severe summer droughts and plant diversity loss disrupt ecosystem functioning and stability of European grasslands. Understanding how these factors interact with pathogens is crucial. We investigated the effects of plant diversity and repeated summer drought on soil‐borne parasites within a grassland biodiversity ...

Loss of E3 ligase HvST1 function substantially increases distal crossover frequency

New Phytologist, Volume 249, Issue 3, Page 1325-1341, February 2026.
Summary This study characterizes the function of a grass‐specific E3 ubiquitin ligase, HvST1, in regulating synapsis and crossover (CO) formation during meiosis in barley (Hordeum vulgare). In large‐genome cereals, COs are predominantly restricted to distal chromosomal regions, limiting genetic recombination and breeding flexibility.
