Heterologous expression of a lycophyte protein enhances angiosperm seedling vigor
Development, 2022 ABSTRACT Seedling vigor is a key agronomic trait that determines juvenile plant performance. Angiosperm seeds develop inside fruits and are connected to the mother plant through vascular tissues. Their formation requires plant-specific genes, such as BREVIS RADIX (BRX) in Arabidopsis thaliana roots.

Functional characterization of NRT1/PTR FAMILY transporters: looking for a needle in a haystack
New Phytologist, Volume 249, Issue 3, Page 1124-1144, February 2026.Summary NRT1/PTR FAMILY (NPF) transporters play crucial roles in plant physiology and development due to their involvement in nitrogen nutrition and their ability to transport multiple signaling molecules and metabolites. Whereas most eukaryotic and prokaryotic NPF orthologs are peptide transporters, most flowering plant NPF transport other substrates ...

Why Do Heterosporous Plants Have So Few Chromosomes?
Frontiers in Plant Science, 2022 The mechanisms controlling chromosome number, size, and shape, and the relationship of these traits to genome size, remain some of the least understood aspects of genome evolution.

Molecular cloning of RBCS genes in Selaginella and the evolution of the rbcS gene family [PDF]
Archives of Biological Sciences, 2015 Rubisco small subunits (RBCS) are encoded by a nuclear rbcS multigene family in higher plants and green algae. However, owing to the lack of rbcS sequences in lycophytes, the characteristics of rbcS genes in lycophytes is unclear.

New Phytologist, Volume 249, Issue 1, Page 448-459, January 2026.Summary Mycorrhizal associations between fungi and plants are a fundamental aspect of terrestrial ecosystems. Mycorrhizas occur in c. 85% of extant plants, yet their geological record remains sparse. Rare fossil evidence from early terrestrial environments offers crucial insights into these ancient symbioses, but visualizing fossil fungi at the ...
