“…Additionally, simple sugars and total nonstructural leaf carbohydrates were higher at beginning and full pod (R3/R4) compared to the earlier soybean growth stages (Rogers et al, 2004). Sengupta et al (2019) also reported an increase in hexose and sucrose concentrations in R5 compared to the R2 leaves, but in drought‐stressed soybean plants.…”

Cercospora leaf blight (CLB) is one of the most important diseases of soybean (Glycine max) in southern USA, with estimated annual losses of about $45 million (Allen et al., 2017). In 2010, CLB was detected in 70% of the surveyed soybean fields in Alabama (Sikora et al., 2011), while estimated yield losses in Louisiana and Mississippi for 2016 were 64,000 (about 4.0% of total yield) and 56,000 tonnes (2.1%), respectively (Allen et al., 2017). CLB is also present in other major soybean-producing countries, including Argentina and Brazil (Soares et al., 2015).Until 2015, Cercospora kikuchii was largely thought to be the sole causal agent of the disease. However, later studies associated CLB with at least three more Cercospora species: C. cf. flagellaris, C. cf.

“…The PPFD on cuvette was provided by a LED external source (A113, Qubit System) which supplies photosynthetically active radiation to the leaf with minimum heat load. Net photosynthesis (A N ), transpiration (E), and stomatal conductance to vapor (g s ) were calculated according to the LoggerPro software (Qubit Systems Inc., Canada) as reported in Sengupta et al 2019. Using the differential CO 2 concentration, which is the difference between the influx and efflux CO 2 (dif. CO 2 ), following the molecular flow (MF) rate, net-photosynthesis was calculated as follows:…”

The contamination of environments by heavy metals has become an urgent issue causing undesirable accumulations and severe damages to agricultural crops, especially cadmium and lead which are among the most widespread and dangerous metal pollutants worldwide. The selection of proper species is a crucial step in many plant-based restoration approaches; therefore, the aim of the present work was to check for early morphophysiological responsive traits in three cultivars of Cynara cardunculus (Sardo, Siciliano, and Spagnolo), helping to select the best performing cultivar for phytoremediation. For all three tested cultivars, our results indicate that cardoon displays some morphophysiological traits to face Cd and Pb pollution, particularly at the root morphology level, element uptake ability, and photosynthetic pigment content. Other traits show instead a cultivar-specific behavior; in fact, stomata plasticity, photosynthetic pattern, and antioxidant power provide different responses, but only Spagnolo cv. achieves a successful strategy attaining a real resilience to metal stress. The capacity of Spagnolo plants to modify leaf structural and physiological traits under heavy metal contamination to maintain high photosynthetic efficiency should be considered an elective trait for its use in contaminated environments.
