Rice is one of the essential crops for human consumption and one of the most commonly farmed cereals on the planet earth, but its growth is severely retarded by excessive salt, which influences rice development and production, leading to economic loss. Salt stress induces osmotic stress and ionic toxicity in rice by altering the environment, leading to water deprivation and accumulation of toxic ions, thereby triggering specific physiological and molecular responses in the rice plants. Many factors may affect rice production and cereal quality via its interaction with salinity. This review focuses on some influential factors (photosynthesis, osmosis, micro and macronutrients, microbial flora, rice growth, development, and genes) that may reduce rice production in saline soils. The review also describes the responsive mechanism of rice to salinity and the genetic susceptibility of rice. In light of the challenges posed by the growing global population and limited agricultural land, it is imperative to consider the influential factors discussed in this review, along with genetic susceptibility to improve rice production in terms of quantity and quality under saline soil conditions.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"253 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-05-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141061161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The development of rice varieties resilient to low soil P has gained significance in ensuring future food security. To address this, 55 parental lines of rice hybrids were evaluated under both low and normal levels of soil P. The evaluation included identifying the presence or absence of the tolerant allele related to the major low soil P tolerance QTL, <i>Pup1</i>, using specific PCR-based markers-namely, K46-1, K46-2, K48 and K59. Stress indices were computed by comparing yields under low soil P (Ys) and normal soil P (Yp) conditions, revealing seven out of 55 parental lines to be categorized as low soil P tolerant. These lines demonstrated minimal yield reduction compared to the checks, with a majority carrying either the complete or partial <i>Pup1</i> locus. Notably, the genotypes PSV-41 and Rasi, lacking the <i>Pup1</i> locus, exhibited superior tolerance under low soil P conditions. Through biplot analysis utilizing Yp and Ys stress indices, promising genotypes such as AYT21, ATR-305, Rasi, RP bio 4919–50–13 and AR 19–42R were identified under low soil P conditions.

The significant increase in cereal grain yield is primarily attributed to the application of inorganic nitrogenous fertilizer. But the inefficient utilization of the fertilizer leads to leftover N, which has a negative impact on human health and the environment. Hence, a pressing priority is to enhance nitrogen use efficiency (NUE) in crop cultivation through improved management practices. Additionally, it is important to assess how NUE interacts with the plant characteristics. NUE depends on the absorption and distribution of nitrogen through enhanced root architecture and transporters, processing, and remobilization within storage organs. Moreover, NUE is determined by N distribution across roots, stems, leaves, grains, photosynthetic capacity, and leaf senescence. Information on the scope of exploitable genetic variability and their genetic control is needed to increase NUE through genetic modifications. In this review, we provide an integrated approach that combines agronomy, physiology, genetics, and genomics for a comprehensive understanding of the critical components involved in NUE. This understanding is crucial for developing crop management practices and identifying promising key genetic factors to improve NUE in cereals.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"1 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140627935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The impact of weeds on rice production is well established, and among PPN, <i>Meloidogyne graminicola</i>, a rice root-knot nematode (RRKN), is becoming a major issue. Although the weeds and RRKN share the same habitat, it is yet unknown how these weeds contribute to the off-season survival of RRKN. Consequently, the current study was done to determine the susceptibility of weeds in the rice wetland ecosystem to RRKN. The weed survey was carried out in rice fields during both crop season and off season, followed by its susceptibility study against RRKN in pot experiment. 24 weed species were discovered to be prevalent including 17 broadleaved weeds (BLW), 5 grassy weeds (GRW) and 2 sedges (SED). Among them the GRW were more frequent (93.33%) and predominant (48.20/0.25 m<sup>2</sup>, 64.71% of all weeds) in the crop season. On the other hand, during the off season, the BLW predominated (55.17/0.25 m<sup>2</sup>, 58.16% of all weeds). Based on our susceptibility test against RRKN, we discovered that, among the 24 weed species, 9 act as good hosts with Build Up Index (BUI) &gt; 10, 4 function as poor hosts with a BUI between 1 and 10, and 11 act as non-hosts with a BUI &lt; 1. We are presenting information on five novel weed species that act as alternate hosts of RRKN for the first time: <i>Macerdonia procumbens, Leptochloa chinensis, Ipomea aquatica, Ammannia baccifera</i> and <i>Eragrostis racemose</i>. The weeds that were observed in both seasons such as <i>Cyanotis axillaris</i> (BUI-16.67), <i>Phyllanthus niruri</i> (BUI-15.97), <i>Macerdonia procumbens</i> (BUI-14.33), <i>Eclipta alba</i> (BUI-14.00), <i>Sphenoclea zeylanica</i> (BUI-13.00) and <i>Echinocloa colona</i> (BUI-15.00) could therefore constitute a serious threat to rice wetland cultivation by assisting the off-season survival of RRKN.

However, the variability in mycorrhizal dependency (MD) and root colonization by AMF among maize variety groups is still poorly documented in the Kivu region. This study aimed to investigate the variation in mycorrhizal dependency to <i>Rhizophagus irregularis</i> among five maize varieties from South-Kivu and one from Senegal using a greenhouse experiment. AMF inoculation significantly influenced the intensity of root colonization, growth and physiology of maize varieties, while no change in root colonization frequency was observed. Three of six varieties used responded positively to AMF inoculation. For these varieties, inoculation with <i>R. irregularis</i> significantly improved plant height, stem diameter and SPAD values. The same significant positive trend was observed for maize total shoot and root biomasses (<i>p</i> &lt; 0.05). Significant variation in MD was observed among maize varieties (<i>p</i> = 0.00012) and could be attributed in part to genetic and physiological factors controlling host/fungus compatibility. The non-metric multidimensional scaling (NMDS) analysis discriminated varieties into two main groups, including those with high MD (MD˃5%) and those with low MD (MD &lt; 5%). The analysis of similarity (ANOSIM) for the mycorrhizal inoculation effect index (<i>R</i> = 0.15 and <i>p</i> = 0.0013), suggested high variability for symbiotic traits. Three varieties showed strong MD and can be used in the field to optimize beneficial effects of AMF on maize productivity or to be used as parents in maize breeding program.</p>","PeriodicalId":9841,"journal":{"name":"Cereal Research Communications","volume":"26 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2024-03-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140167298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
