Hormone-based biostimulants like brassinosteroids (BRs) modulate growth/defence trade-off, mitigating yield losses; yet, natural molecule's low stability challenges the development of cost-effective and long-lasting analogues. Here, we investigated for the first time the effects of BR functional analogue DI-31 in soybean physiology under drought by assessing changes in growth, photosynthesis, water relations, antioxidant metabolism, nodulation, and nitrogen homeostasis.

However, a major bottleneck lies in phenotyping, particularly in selecting cost-efficient markers associated with stress tolerance and yield stabilization. Here, we conducted in-depth phenotyping experiments in two soybean genotypes with contrasting drought tolerance, MUNASQA (tolerant) and TJ2049 (susceptible), to better understand soybean stress physiology and identify/statistically validate drought-tolerance and yield-stabilization traits as potential breeding markers.

Objectives of the present research were to (i) study the genetic and pathogenic diversity in a collection of M. phaseolina isolates from Argentina and Paraguay and (ii) develop an improved in vitro phenotyping method to evaluate disease response of soybean genotypes to M.

- The study aimed to identify molecular markers linked to yield-related traits in sugarcane using a genome-wide association analysis (GWAS) method tailored for a breeding population across multiple crop cycles.
- A total of 43 markers related to cane yield (CY) were discovered, some consistent over two years, along with numerous significant associations for sugar content (SC) markers, indicating the method's effectiveness in capturing these agricultural traits.
- The findings suggest advancements in sugarcane breeding can be achieved through the novel multi-QTL analysis approach, providing insights into the genetic similarities with Sorghum bicolor, which may enhance breeding efficiency.
