Grain and forage legumes are important sources of food feed, key for sustainable agriculture given the environmental services they provide. However, their cultivation is hampered in Mediterranean Basin Near East by widespread occurrence root parasitic weed crenate broomrape (Orobanche crenata). Other species such as O. minor, foetida, Phelipanche aegyptica also local importance. As other weeds, a number management strategies have been proposed, but considering that temperate area low-input crops, these largely uneconomical or hard to achieve, leaving use resistant cultivars most desirable option. Breeding resistance not an easy task, significant progress has achieved classical breeding selection will profit from recent developments phenomics genomics. Here, achievements prospects presented critically discussed.

Pigeonpea, a climate-resilient legume, is nutritionally rich and of great value in Asia, Africa, Caribbean regions to alleviate malnutrition. Assessing the grain nutrient variability genebank collections can identify potential sources for biofortification. This study aimed assess genetic nutrients set 600 pigeonpea germplasms conserved at RS Paroda Genebank, ICRISAT, India. The field trials conducted during 2019 2020 rainy seasons augmented design with four checks revealed significant differences among genotypes all agronomic traits studied. germplasm had wider variation like days 50% flowering (67-166 days), maturity (112-213 100-seed weight (1.69-22.17 g), yield per plant (16.54-57.93 g). A good was observed nutrients, namely, protein (23.35-29.50%), P (0.36-0.50%), K (1.43-1.63%), Ca (1,042.36-2,099.76 mg/kg), Mg (1,311.01-1,865.65 Fe (29.23-40.98 Zn (24.14-35.68 Mn (8.56-14.01 Cu (7.72-14.20 mg/kg). from Asian region varied widely ones African high density. genotype × environment interaction most (except P, K, Ca) indicated sensitivity accumulation environment.

Accuracy of Selection in Early Generations of Field Pea Breeding Increases by Exploiting the Information Contained in Correlated Traits

Plants, Год журнала: 2023, Номер 12(5), С. 1141 - 1141

Опубликована: Март 2, 2023

Accuracy of predicted breeding values (PBV) for low heritability traits may be increased in early generations by exploiting the information available correlated traits. We compared accuracy PBV 10 with to medium narrow-sense (h2) a genetically diverse field pea (Pisum sativum L.) population after univariate or multivariate linear mixed model (MLMM) analysis pedigree information. In contra-season, we crossed and selfed S1 parent plants, main season evaluated spaced plants S0 cross progeny S2+ (S2 higher) self Stem strength included stem buckling (SB) (h2 = 0.05), compressed thickness (CST) 0.12), internode length (IL) 0.61) angle above horizontal at first flower (EAngle) 0.46). Significant genetic correlations additive effects occurred between SB CST (0.61), IL EAngle (-0.90) (-0.36). The average PBVs from 0.799 0.841 0.835 0.875 vs MLMM, respectively. An optimized mating design was constructed optimal contribution selection based on an index traits, gain next cycle ranged 1.4% (SB), 5.0% (CST), 10.5% -10.5% (IL), achieved parental coancestry 0.12. MLMM improved potential annual cycles generation increasing PBV.

Abstract Pea, ( Pisum sativum , Leguminaceae), also called garden pea is herbaceous annual plant grown worldwide for its edible seeds. Several studies reported that about 20 insect pest attack this crop and cause substantial yield loss.

Lemon zinc finger protein ClSUP induces the accumulation of reactive oxygen species and inhibits citrus yellow vein-clearing virus infection via interactions with ClDOF3.4

Journal of Experimental Botany, Год журнала: 2024, Номер 75(22), С. 7300 - 7316

Опубликована: Авг. 26, 2024

Abstract Citrus yellow vein-clearing virus (Potexvirus citriflavivenae; CYVCV) is an increasing threat to citrus cultivation. Notably, the role of zinc finger proteins (ZFPs) in mediating viral resistance plants unclear. In this study, we demonstrated that ZFPs ClSUP and ClDOF3.4 enhanced defense responses against CYVCV Eureka lemon (Citrus limon ‘Eureka’). interacted with coat protein (CP) reduce CP accumulation inhibited its silencing suppressor function. Overexpression CISUP triggered reactive oxygen species (ROS) salicylic acid (SA) pathways, infection. contrast, resulted increased down-regulated ROS SA-related genes. facilitate interactions CP. Furthermore, synergistically regulated SA accelerated down-regulation accumulation. Transgenic co-expressing significantly decreased CYVCV. These findings provide a new reference for understanding interaction mechanism between host
