Lateral transfers lead to the birth of momilactone biosynthetic gene clusters in grass. [PDF]

Plant J, 2022
SUMMARY Momilactone A, an important plant labdane‐related diterpenoid, functions as a phytoalexin against pathogens and an allelochemical against neighboring plants. The genes involved in the biosynthesis of momilactone A are found in clusters, i.e., momilactone A biosynthetic gene clusters (MABGCs), in the rice and barnyardgrass genomes.

Pathogen effectors: What do they do at plasmodesmata? [PDF]

Mol Plant Pathol, 2022
Many pathogen effectors are delivered to the cytosol and suppress callose accumulation at the apoplast or plasmodesmata; some undergo cell‐to‐cell symplasmic trafficking and physically interact with plasmodesmata regulators. Abstract Plants perceive an assortment of external cues during their life cycle, including abiotic and biotic stressors.

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]

Plant Genome
Abstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.

Structure-guided insights into the biology of fungal effectors. [PDF]

New Phytol
Summary Phytopathogenic fungi cause enormous yield losses in many crops, threatening both agricultural production and global food security. To infect plants, they secrete effectors targeting various cellular processes in the host. Putative effector genes are numerous in fungal genomes, and they generally encode proteins with no sequence homology to ...

Phytolith Content Negatively Affects Forage Quality of Eragrostis curvula (Schrad.) Nees

Agronomy, 2023
Phytoliths are intra and extracellular siliceous deposits present in different plant tissues. Si uptake and transport are mediated by Lsi genes and its concentration is associated with forage quality.

Host Specificity Controlled by PWL1 and PWL2 Effector Genes in the Finger Millet Blast Pathogen Magnaporthe oryzae in Eastern Africa

Molecular Plant-Microbe Interactions, 2023
Magnaporthe oryzae, a devastating pathogen of finger millet (Eleusine coracana), secretes effector molecules during infection to manipulate host immunity. This study determined the presence of avirulence effector genes PWL1 and PWL2 in 221 Eleusine blast

Challenges, successes, and recommendations for management of coastal sandplain grasslands as regional biodiversity hotspots in the northeastern United States

Restoration Ecology, Volume 31, Issue 5, July 2023., 2023
A high proportion of regional plant biodiversity occurs in hotspots of species richness that cover small areas created and maintained by disturbance. Sustaining plant diversity in these areas requires region‐ and habitat‐specific management of disturbance and, increasingly, habitat expansion or restoration to offset species losses.

Precision Editing of NLRS Improves Effector Recognition for Enhanced Disease Resistance. [PDF]

Adv Sci (Weinh)
Precision engineering of plant NLR immune receptors enables rational design of enhanced pathogen resistance through mismatched pairing, domain swapping, and targeted mutagenesis. These approaches achieve multi‐fold expansion in recognition breadth while minimizing autoimmunity risks and fitness penalties.

Carbon sequestration and water management in Texas—One size does not fit all

Agrosystems, Geosciences &Environment, Volume 6, Issue 2, June 2023., 2023
Abstract Climate‐smart agriculture (CSA) is an integrated approach to sustainably meeting food, fiber, and feed production needs. The technical and socioeconomic feasibility of different CSA strategies depends on local conditions, and there is no one‐size‐fits‐all approach.

Simulated distribution of Eragrostis lehmanniana (Lehmann lovegrass): Soil–climate interactions complicate predictions

Ecosphere, Volume 13, Issue 3, March 2022., 2022
Abstract The invasive perennial grass Eragrostis lehmanniana has expanded rapidly throughout the Sonoran Desert (SD) while remaining sparse and patchily distributed in the neighboring Chihuahuan Desert (CD). As temperatures and patterns in precipitation change, identifying the drivers limiting spread in the CD is needed.
