Photocatalytic Cross‐Coupling of Phenols and Heteroaryl Halides With Machine Learning‐Guided Reaction Prediction

Angewandte Chemie International Edition, EarlyView.
Photocatalytic cross‐coupling: A redox‐neutral photochemical method enables direct C(sp2)─C(sp2) bond formation between phenols and heteroaryl halides using an organic dye and base. Complementary radical generation allows efficient cross‐coupling in up to 91% yield. Mechanistic studies, DFT, HTE, and machine learning rationalize and predict reactivity,

Thirty years of glyphosate‐resistant crops and weeds: Current situation and future prospects

Pest Management Science, EarlyView.
Since 1996, when the first glyphosate‐resistant crop was commercialized and the first resistant weed was reported, resistance has expanded globally. This review analyzes emergence patterns across weed species, crops, regions, resistance mechanisms, and herbicides.

Coupling of both a transactivation module and a double‐stranded DNA‐binding domain boosts Cas12i3 variant‐based cytosine and adenine editing in plants

Journal of Integrative Plant Biology, EarlyView.
Fusions of a transactivation module and a double‐stranded DNA‐binding domain produced effective Cas12i3 variant‐based cytosine and adenine base editors, with improved C‐to‐T and A‐to‐G base editing efficiency and expanded editing window. Generated herbicide‐resistant rice germplasm by using these base editors demonstrates their potential for precise ...

Enhancing CRISPR‐Cas12a base editing in plants with LbCas12a variants and introns

Journal of Integrative Plant Biology, EarlyView.
Intron optimization of LbCas12a‐RRV improves cytosine and adenine base editing efficiency in plants, supports multiplexed and double‐strand break‐free genome modification, and expands precise genome engineering tools for crop breeding and plant functional research. ABSTRACT Cytosine base editors (CBEs) and adenine base editors (ABEs) are powerful tools

Dependent Articulation in the Global Pesticide Complex: Argentina's Agrochemical Industry After the Generics Market Revolution

Journal of Agrarian Change, EarlyView.
ABSTRACT Since the late 1990s, the pesticide industry has undergone a ‘generics revolution’ as the centre of production, and trade has shifted to the global South. China and India have become major producers, capturing Latin American markets from Northern multinationals. As a major pesticide user and a key node in global supply chains, Argentina offers
