“…CaNAC100 belongs to the NAC family of TFs that regulate a wide array of developmental programmes and stress responses in plants (Wang et al ., 2020, 2021). An earlier report by Verma & Bhatia (2019) had indicated CaNAC100 to be positively co‐expressed with SSPs in chickpea; however, the exact mechanism by which the candidate gene determines the SPC remained unknown (Basu & Parida, 2023). Thus, the current investigation sought to functionally validate the TF as well as identify the key components of the CaNAC100 signalling pathway during chickpea seed maturation.…”

“…Using RNA-Seq expression data of developing seeds, Verma & Bhatia (2019) identified 14 genes including members of the NAC, bZIP, B3, C3H, and AP2 TF families that were significantly co-expressed along with 11 major seed maturation-specific SSPs of chickpea. However, none of these TFs have been functionally assessed for their involvement in governing SPC; hence, the intricate transcriptional regulatory network that determines the synthesis of these storage proteins in chickpea necessitates investigation (Basu & Parida, 2023).…”

Summary Development of protein‐enriched chickpea varieties necessitates an understanding of specific genes and key regulatory circuits that govern the synthesis of seed storage proteins (SSPs). Here, we demonstrated the novel involvement of Ca‐miR164e‐CaNAC100 in regulating SSP synthesis in chickpea. Ca‐miRNA164e was significantly decreased during seed maturation, especially in high‐protein accessions. The miRNA was found to directly target the transactivation conferring C‐terminal region of a nuclear‐localized transcription factor, CaNAC100 as revealed using RNA ligase‐mediated‐rapid amplification of cDNA ends and target mimic assays. The functional role of CaNAC100 was demonstrated through seed‐specific overexpression (NACOE) resulting in significantly augmented seed protein content (SPC) consequential to increased SSP transcription. Further, NACOE lines displayed conspicuously enhanced seed weight but reduced numbers and yield. Conversely, a downregulation of CaNAC100 and SSP transcripts was evident in seed‐specific overexpression lines of Ca‐miR164e that culminated in significantly lowered SPC. CaNAC100 was additionally demonstrated to transactivate the SSP‐encoding genes by directly binding to their promoters as demonstrated using electrophoretic mobility shift and dual‐luciferase reporter assays. Taken together, our study for the first time established a distinct role of CaNAC100 in positively influencing SSP synthesis and its critical regulation by CamiR164e, thereby serving as an understanding that can be utilized for developing SPC‐rich chickpea varieties.

“…Several factors contribute in the formation of grain yield and seeding at the best time greatly influences final crop production (Basu and Parida, 2023;Richards et al, 2022;Shah et al, 2020). The data revealed that sowing during the last-week of October to the first week of November at the already established distance of 15cm P-P and 30cm R-R and an application of one bag of DAP (di-ammonium phosphate) fertilizer at the time of land preparation is best for achieving maximum production of Noor-2019.…”

Over the years, a crop variety grown on the commercial scale and under different conditions becomes vulnerable to various kinds of issues involving both biotic and abiotic plant stresses, alone or in combinations. This demands their substitution with new and improved genotypes possessing higher productivity and inherent resistance/tolerance against yield-limiting stresses. In this context, this editorial reports the development of a new chickpea kabuli variety "Noor-2019". This cultivar has improved yield potential, dietary elements (proteins, fat, ash), and more importantly, resistance against fusarium wilt and ascochyta blight compared to the existing varieties. The evolution of this strain commenced in 2002-03 cropping season by crossing K-90399 as a female parent with K-52582 as a male parent. The female parent had high yield potential, whereas the male parent had wilt resistance and was developed through introgression breeding using ILWC-126, an accession of Cicer reticulatum. Henceforth, the genetic variability was created to select for high yield and wilt resistant recombinants in subsequent generations. Resultantly, a uniform and high yielding progeny line PCK-09012, later designated as "Noor-2019" was selected and evaluated for yield, agronomy, and insect pests. This cultivar revealed a potential yield of 2882 kg ha -1 in testing phase and outperformed standard checks by producing 78.2%, 13.1%, and 28.8% higher grain yield in station, adaptation and national uniform yield trials, respectively. The plants of Noor-2019 are 60-65cm tall, semi-erect, and medium in canopy spread. Its grains are light brown, ram-headed, medium in size with a 100-seed weight of 25 g. Adoption of this cultivar across different climatic regions of Punjab, and other provinces could contribute in attaining self-sufficiency in local chickpea production as well as plummeting import bill.
