Grass Communities Differ Floristically Under Different Dominant Trees in Savannas in Thailand and Cambodia

Biotropica, Volume 58, Issue 2, March 2026.
In total, we recorded 160 unique grass species across four savanna ecosystems dominated by different tree genera. These savannas support distinct grassy assemblages, but common grasses are often shared between ecosystems. ABSTRACT Southeast Asian savannas are some of the least studied ecosystems, with understanding of their function and resilience ...

Modulation of SAL retrograde signalling promotes yield and water productivity responses in dynamic field environments

New Phytologist, Volume 249, Issue 3, Page 1219-1233, February 2026.
Summary Chloroplast‐to‐nucleus retrograde signalling enables rapid stress responses in plants, but whether these signals accumulate to affect crop performance across entire growing seasons under field conditions remains unknown. We generated wheat mutants with targeted deletions in specific SAL gene copies from two distinct homeologous groups (TaSAL1 ...

NADP-Malate Dehydrogenase Gene Evolution in Andropogoneae (Poaceae): Gene Duplication Followed by Sub-functionalization [PDF]

, 2017
• Background and Aims Plastid NADP-dependent malate dehydrogenase (MDH) catalyses the conversion of oxaloacetate to malate. In C4 plants, it is involved in photosynthetic carbon assimilation. In Poaceae, one NADP-MDH gene has been identified in rice (C3;

Environmental changes on grass flowering phenological trends (2000–2021)

PLANTS, PEOPLE, PLANET, Volume 7, Issue 6, Page 1824-1833, November 2025.
Climate change is impacting the flowering of grasses, which in turn impacts the health of people due to allergic reactions triggered by grass pollen. The timing of flowering was studied for 15 grass species across various habitats in the Cordoba region of Spain.
