Phosphorus (P) is the second-most essential macronutrient required for the growth and development of plants. It is involved in a number of cellular processes that contribute to the plant’s growth and development. This study investigated Saccharum spp. hybrid and Sorghum bicolor promoter regions of Phosphate transporters (PHT), viz., PHT1, PHT2, PHT...

The phosphate transporter (PHT) family of proteins plays an imperative role in regulating phosphorus (P) acquisition as well as in translocation from the soil into cells and organs. Phosphorus is an essential macronutrient required for plant life that is not readily available to crops, and resources are diminishing rapidly because of the huge needs...

Abstract Erianthus arundinaceus [Retzius] Jeswiet, a wild relative of sugarcane has a high biomass production potential and a reservoir of many genes for superior agronomic traits and tolerance to biotic and abiotic stresses. A comparative physiological, anatomical and root transcriptome analysis were carried out to identify the salt-responsive gen...

Sugarcane is a C4 and agro-industry-based crop with a high potential for biomass production. It serves as raw material for the production of sugar, ethanol, and electricity. Modern sugarcane varieties are derived from the interspecific and intergeneric hybridization between Saccharum officinarum, Saccharum spontaneum, and other wild relatives. Suga...

Sugarcane is a trans-seasonal long-duration crop and tillering phase (60–150 days) is the most sensitive phase for moisture stress, causing significant reduction in biomass accumulation. The study focussed to assess the Genotype × Environment Interaction (GEI) for tillering phase moisture stress and to identify the stable genotypes in sugarcane. Th...

The utilization of superior parental lines and identification of superior families enhance the genetic gain in sugarcane. To identify the superior parental lines and superior progenies, 1889 progenies derived from twenty crosses involving genetically diverse historical parents were evaluated for juice quality and yield attributing traits.The hist...

Plant nuclear factor (NF-Y) is a transcription activating factor, consisting of three subunits, and plays a key regulatory role in many stress-responsive mechanisms including drought and salinity stresses. NF-Ys function both as complex and individual subunits. Considering the importance of sugarcane as a commercial crop with high socio-economic im...

Field experiments were conducted during 2016-17 and 2017-18 crop seasons with twenty test clones viz., Co 0238, Co 0240, Co 06031, Co 09004, Co 11015, Co 13001, Co 13003, Co 13006, Co 13014, Co 13018, Co 13020, Co 13021, Co 14008, Co 14016, Co 14026, Co 15005, Co 15007, Co 15021, Co 16001 and Co 16002 along with three standards viz., Co 86032, Co 0...

A DESCRIPTION OF Co 11015 (ATULYA) A RECENTLY NOTIFIED SUGARCANE VARIETY FOR TAMIL NADU

Sugarcane (Saccharum sp.) hybrids belonging to Poaceae family is cultivated for sugar and biofuels across the world as well in India. Low-temperature (LT) stress is known to restrain sugarcane productivity in subtropical regions significantly. During LT stress, susceptible sugarcane varieties show abnormalities including photosynthetic rate reducti...

Low-temperature (LT) stress is known to restrain sugarcane productivity in sub-tropical India significantly. Many researchers have prioritized their work towards developing climateresilient sugarcane varieties through the incorporation of genome of stress-tolerant sugarcane related wild-type species in the pre-breeding program. However, the lack of...

Co 10026 (UPAHAR): New Early Maturing Variety Released for Cultivation in Peninsular Zone

Sugarcane (Saccharum sp.) is predominantly grown in both tropics and subtropics in India, and the subtropics alone contribute more than half of sugarcane production. Sugarcane active growth period in subtropics is restricted to 8–9 months mainly due to winter’s low temperature stress prevailing during November to February every year. Being a commer...

Rice genotypes BPT5204 and HP14, their direct and reciprocal F1s (DF1&RF1), F2populations (DF2&RF2) and recombinant inbred lines (RILs) were evaluated to study the genetics of field resistance to sheath rot disease (ShR). Observed frequencies of resistant and susceptible plants in DF2and RILs showed 27R:37S ratio and 1R:7S ratio indicating involvem...

Sugarcane is a C4 grass grown in tropical and subtropical regions, cultivated in 22 million hectares in more than 100 countries (FAOSTAT 2008, http://faostatfaoorg/defaultaspx). Major sugar requirement of the world is met by sugarcane. It contributes almost 75% of total sugar produced from all the sugar crops. Sugarcane is also used for generation...

Accurate measurement of parameters contributing to diseases and their symptoms is important for identification of resistant genotypes. Present sheath rot scoring system such as disease incidence scoring system accounts for only percentage of disease incidence and not the disease severity. Disease severity scoring system is based on combined feature...

Sheath rot disease caused by Sarocladium oryzae is an emerging threat for rice cultivation at global level. However, limited information with respect to genomic resources and pathogenesis is a major setback to develop disease management strategies. Considering this fact, we sequenced the whole genome of highly virulent Sarocladium oryzae field isol...

Genomic constitution of commercially cultivated sugarcane varieties over the world is derived from few basic species clones of Saccharum complex. In order to impart new cytoplasmic and nuclear genome in sugarcane hybrids, untapped wild species of Saccharum spontaneum (S), Erianthus arundinaceus (E) and E. bengalense (Eb) were utilized to produce di...

Symbiotic effect of twenty one indigenous Bradyrhizobium yuanmingense strains obtained from nodules of soybean cultivated in India was comparatively evaluated with B. japonicum ASR011 on soybean cv. JS335 for improved nodulation and plant growth performance under greenhouse conditions. Significant variation in symbiotic potential among native B. yu...

Restriction fragment length polymorphism (RFLP) of nifH gene with three endonucleases revealed three different nifH genotypes among twenty one indigenous Bradyrhizobium yuanmingense strains. The interactive symbiotic effectiveness on soybean cv. JS335, nodulation and plant growth of these B. yuanmingense strains were comparatively evaluated with B....
