Sugarcane, which provides 80% of global table sugar and 40% of biofuel, presents unique breeding challenges due to its highly polyploid, heterozygous, and frequently aneuploid genome. Significant progress has been made in developing genetic resources, including the recently completed reference genome of the sugarcane cultivar R570 and pan-genomic resources from sorghum, a closely related diploid species

Flowering time is a key agronomic trait that determines the adaptability of crops to the environment and thus affects yields. The mechanism underlying flowering time is still far from clear in Brassica napus. In this study, a recombinant inbred line population composed of 215 lines was constructed and 35 flowering time QTLs were identified. One major QTL, qFT.A02-1 (explaining 16.40–17.80% of phenotypic variation), was detected in two environments,

Difficulties exist in obtaining full-length, correctly folded, and soluble papain or papain-like proteases that necessitate the exploration of alternative strategies. This study describes the development of an Escherichia coli strain capable of producing soluble papain without the need for complex and time-consuming in vitro refolding steps. To enhance the production of soluble papain, engineered T7 promoters and a recombinant papain translationally fused with varying tags were constructed.

The brown planthopper (BPH) is a significant piercing-sucking pest of rice plants that causes widespread destruction globally. Discovering new germplasms and genes for BPH resistance is essential for enhancing genetic diversity in rice breeding. In this study, 4006 rice accessions from tropical and subtropical regions were screened for BPH resistance at the seedling stage, and 63 accessions with high-resistant were identified. Of these, 59 accessions exhibited high resistance to BPH at the adult stage.

Parasitism with Striga poses a major threat to global food production. Striga germination and growth rely on strigolactones (SLs) exuded by crop roots under phosphate (Pi)-deficient conditions, although the mechanism of this host-parasite interaction remains elusive. In this study, transcriptomic and functional analyses of sorghum treated with Pi deficiency or the SL GR24^5DS identify two ABC transporter G (ABCG) transporters of SL, Sorghum biocolor strigolactones transporter 1 (SbSLT1) and SbSLT2.

The remarkable evolutionary history of the common bean (Phaseolus vulgaris L.) has led to the emergence of three wild main gene pools corresponding to three different eco-geographical areas: Mesoamerica, the Andes and northern Peru/Ecuador. Recent works proposed novel scenarios, and the northern Peru/Ecuador population has been described as a new species called P. debouckii, rekindling the debate about the origin of P. vulgaris.

The two-line hybrid rice system, a cutting-edge hybrid rice breeding technology, has greatly boosted global food security. In thermo-sensitive genic male sterile (TGMS) lines, the critical sterility-inducing temperature (CSIT; the temperature at which TGMS lines change from male fertile to complete male sterile) acts as a key threshold. We recently uncovered that thermo-sensitive genic male sterility 5 (tms5), a sterile locus presenting in over 95% of TGMS lines,

Tomato leaf curl New Delhi virus (ToLCNDV), a begomovirus, that causes severe leaf curling, stunting, and reduced yield in tomato plants is consistently threatening its production worldwide. CRISPR/Cas9-mediated genome editing has shown immense potential in developing disease-resistant crops. This study successfully focuses on designing a precise and efficient strategy for in planta defence against ToLCNDV.

Submergence stress is a major obstacle limiting the application of direct seeding in rice cultivation. Rapid bud and root growth helps plants establish a stronger growth base and improve their submergence tolerance. Therefore, mining genes for bud length (BL) and root length (RL) helps in the development of varieties that are adaptable to submergence and improve seedling emergence and yield of direct-seeded rice.

In agroecosystems, plants are constantly exposed to attack from diverse herbivorous insects and microbes, and infestation with one species may change the plant defense response to other species. In our investigation of the relationships among rice plants, the brown planthopper Nilaparvata lugens (Stål) and the rice blast fungus Magnaporthe oryzae, we observed a significant increase in the resistance of rice treated with rice blast to N. lugens, as evidenced by improved plant survival rates in a small population resistance study.
