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.

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 ...

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.

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.

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.

Pyricularia oryzae: Lab star and field scourge. [PDF]

Mol Plant Pathol
The fungal pathogen Pyricularia oryzae (syn. Magnaporthe oryzae) is the causal agent of blast disease on cereals and grasses and a model organism in plant–pathogen interaction research. Abstract Pyricularia oryzae (syn. Magnaporthe oryzae), is a filamentous ascomycete that causes a major disease called blast on cereal crops, as well as on a wide ...

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.

Forage conservation in sub‐Saharan Africa: Review of experiences, challenges, and opportunities

Agronomy Journal, Volume 114, Issue 1, Page 75-99, January/February 2022., 2022
Abstract Forage conservation is an important potential solution to seasonal variation in feed quality and quantity and herder‐farmer conflicts in sub‐Saharan Africa (SSA). Considerable variations exist in the type of forages conserved and the preservation methods across SSA. Hay from cultivated forages is commonly made with mechanical mowers and balers

Scaling up private land conservation to meet recovery goals for grassland birds

Conservation Biology, Volume 35, Issue 5, Page 1564-1574, October 2021., 2021
Abstract Long‐term population declines have elevated recovery of grassland avifauna to among the highest conservation priorities in North America. Because most of the Great Plains is privately owned, recovery of grassland bird populations depends on voluntary conservation with strong partnerships between private landowners and resource professionals ...
