Abstract CONTEXT OR PROBLEM Forage maize is a central pillar of dairy cow feeding in France, directly influencing milk production. Drought significantly affects both yield and digestibility, which are key parameters required for hybrid registration purposes. OBJECTIVE RESEARCH QUESTION Research on inbred lines has revealed droughts’ notable effect dry matter cell wall digestibilities due to changes composition, impacting forage quality. No such studies have been performed hybrids however, the main seed type used agricultural sector. In this paper, we aimed understand impact water heat stress uncover factors controlling it. METHODS We grew range modern two years under four different controlled modalities. These plants were agronomically, biochemically histologically assayed, allowing us perform multiscale analysis determine traits responsible variations digestibility. RESULTS By establishing comprehensive index, classified environmental conditions. demonstrated that severe stress, ear production decreases significantly, but digestibility can be maintained through increased This boost was reduction p -hydroxycinnamic acid content lignin distribution, while structure remained stable. The significant distribution with severity reaching an extreme threshold where biochemical solely account variations. CONCLUSION AND IMPLICATIONS To improve it will necessary better how carbon flux levels without greatly content. Finally, our work suggests inclusion moderate conditions future breeding programs adapt climate change.

Abstract Woody plants minimize xylem embolism formation during drought essentially by closing stomata at higher water potentials and/or increasing the resistance to embolism. Both of these mechanisms result in a stomatal safety margin (SSM), which is potential difference between closure and formation. Here, we investigated whether SSM represents mechanism for herbaceous how different water‐use strategies impact their survival. For that, exposed four crops with contrasting severe deficit assess drought‐induced damage mortality. Unlike woody species, was not associated plant survival crops. Soybean, presented largest across (1.67 MPa), exhibited earliest mortality leaves whole as well highest rate (100%) end period. Cowpea, an 0.63 MPa, most drought‐resistant latest leaf (100%). The effective traits ensuring under were those related avoidance such (1) early closure, (2) very low residual transpiration post‐stomatal (3) high capacitance pre‐ post‐turgor loss.

Agricultural water productivity, defined as the amount of grain produced per unit available water, is an important sustainability criterion in modern crop production. Although genetic progress maize has increased yields, there are limited studies on role plant breeding this metric. In center US corn-belt, rainfed yields have more than tripled since 1950 while relying same inputs. Our analysis shows that shift production resulted a productivity increase 0.191 kg ha-1 mm-1 year-1, corresponding to relative rate 4.2% and result both higher biomass harvest index (i.e., proportion total biomass).

Nitric oxide (NO) and other reactive nitrogen species (RNS) are considered to be signaling molecules in higher plants involved the regulation of growth development processes. However, molecular mechanisms their formation, removal, participation plant responses adverse environmental stimuli remain largely unclear. Therefore, aim this study was assess influence selected single stresses combined (i.e., Rhopalosiphum padi L. aphid infestation, drought, drought) post-stress recovery on contents NO peroxynitrite anion (ONOO−), as well levels mRNA protein nitration 8-nitroguanine 3-nitrotyrosine amounts, respectively), maize seedlings (Zea mays L.). Moreover, expression patterns two tested genes (nos-ip, encoding nitric synthase-interacting protein, nr1, nitrate reductase 1) metabolism were quantified. We identified significant intervarietal, time-course, stress-dependent differences quantified parameters. Under investigated stress conditions, aphid-resistant Waza cv. characterized by a earlier accumulation level an increased target (nos-ip nr1), compared aphid-susceptible Złota Karłowa seedlings. Conversely, responded with greater elevation content ONOO− than The multifaceted role its derivatives challenged stresses, during recovery, is discussed.
