Abstract:
... Turnip (Brassica campestris L. ssp. rapifera Matag syn. B. rapa L.) is characterized by bulbous hypocotyl-tuber, which is an important agronomic trait of the Brassica plants, but the molecular mechanism underlying the development of turnip hypocotyl-tuber has rarely been explored. Contrary to turnip, pak-choi (B. campestris L. ssp. chinensis Makino syn. B. rapa ssp. chinensis) is characterized by ...

Abstract:
... Heading date (or flowering time), an important agronomic trait in crop species, is closely associated with regional adaptation and yield. Members of the Pseudo-Response Regulator (PRR) family play key roles in regulating flowering. However, their role and molecular mechanism controlling heading date in rice is not very clear. Here, we identified rice OsPRR protein, OsPRR59, which delayed heading u ...

Abstract:
... Most existing agronomic trait models of winter wheat vary across growing seasons, and it is an open question whether a unified statistical model can be developed to predict agronomic traits using a vegetation index (VI) across multiple growing seasons. In this study, we constructed a hierarchical linear model (HLM) to automatically adapt the relationship between VIs and agronomic traits across gro ...

Abstract:
... Flowering time is an important agronomic trait in Brassica rapa and has a wide range of variation. The change from vegetative to reproductive development is a major transition period, especially in flowering vegetable crops. In this study, two non-heading Chinese cabbage varieties with significantly different flowering times, Pak-choi (B. rapa var. communis Tesn et Lee) and Caitai (B. rapa var. ts ...

Abstract:
... Clarifying cultivation techniques and making production systems more efficient are practices that have been much sought after in agricultural systems in recent decades. In this context, the forage yield, biological efficiency, and competitive ability, of different cultivation strategies for intercropping forage cactus and sorghum were determined in biosaline production systems from 2018 to 2020 in ...

Abstract:
... The use of pigmented corn hybrids for specialty food uses, such as pozole-making, has increased significantly lately. This work aimed to evaluate 25 non-conventional (native landraces x endogamic lines) corn hybrids (NCH) for yield, precocity, grain physical and pasting properties as well as anthocyanins content to identify genotypes with good market potential for pozole end-use. Genotypes were gr ...

Abstract:
... Cereal grain weight is an important agronomic character, influencing crop yield and quality. The high-amylose cereals usually have grains with different weights. However, it is unclear whether starches from kernels with different weights have different structural properties. In the research, the amylose content, amylopectin structure, crystallinity, and thermal properties of single-kernel starch w ...

Abstract:
... The study aimed to analyze the agronomic performance of 11 safflower genotypes using adaptability and stability methods, while identifying safflower genotypes with stable behavior and a high grain yield in different environments of the Brazilian Cerrado. Ten lines and a cultivar of safflower were evaluated in four environments in the Brazilian conditions. Our results revealed the genotypes P30, P3 ...

Abstract:
... Adenine base editors (ABEs), which are generally engineered adenosine deaminases and Cas variants, introduce site‐specific A‐to‐G mutations for agronomic trait improvement. However, notably varying editing efficiencies, restrictive requirements for protospacer‐adjacent motifs (PAMs) and a narrow editing window greatly limit their application. Here, we developed a robust high‐efficiency ABE (PhieAB ...

Abstract:
... Heading date is an essential agronomic trait that affects adaptability and yield in rice (Oryza sativa). HSFs (heat shock transcription factors) are a type of transcription factor that responds to environmental stress in organisms. The relationship between the heading date and HSFs has been seldom reported so far. Here, we identified a new heat shock transcription factor, named DELAYED HEADING DAT ...
agronomictraits, etc ; Rosa hybr.; ethylene; flower size; flowers; gene expression regulation; genes; sequence analysis; transcription factors; Show all 9 Subjects
Abstract:
... Flower size, a primary agronomic trait in breeding of ornamental plants, is largely determined by petal expansion. Generally, ethylene acts as an inhibitor of petal expansion, but its effect is restricted by unknown developmental cues. In this study, we found that the critical node of ethylene-inhibited petal expansion is between stages 1 and 2 of rose flower opening. To uncover the underlying reg ...

Abstract:
... Plant height is the main agronomic character used to measure the vertical growth and developmental abilities of plant. Cucumber is a popular greenhouse vegetable in Northwest China, and its production is principally limited by water and temperature. However, few studies have simulated water- and temperature-driven cucumber heights in solar greenhouses; in this paper, we explored these optimum grow ...
... Leaf shape represents a vital agronomic trait for leafy vegetables such as lettuce. Some lettuce cultivars produce lobed leaves, varying from pinnately to palmately lobed, but the genetic mechanisms remain unclear. In this study, we cloned one major quantitative trait locus (QTL) controlling palmately lobed leaves. The candidate gene, LsKN1, encodes a homeobox transcription factor, and has been sh ...

Abstract:
... In this study, we successfully introgressed and validated Yr59 into four elite wheat cultivars, Jimai 22, Chuanmai 42, Zhengmai 9023 and Xinmai 26 through marker-assisted backcross selection. Used as female parents, these four cultivars were crossed with wheat line PI 660061 (Yr59). After two backcrosses and marker-assisted selection, the progenies were selfed and advanced to the BC₂F₄ generation. ...

... Biostimulants have become highly important in agriculture. For these products to be efficient, they need to be formulated, for a specific crop, according to the mineral nutrients and metabolites requirements in each phenological phase of the crops. In this study, the agronomical behavior of 10 tomato varieties was evaluated (‘Cherry’, ‘Corazón de Buey’, ‘Green Zebra’, ‘Marglobe’, ‘Marmande VR’, ‘M ...

Abstract:
... Growth duration is an important agronomic trait that determines the season and area of crop growth. Previous experiments showed that overexpression of nitrate transporter OsNRT2.3b significantly increased rice yield, nitrogen use efficiency, and growth duration. Through screening, we obtained four ethyl methanesulfonate (EMS)-mutagenized mutants with shorter growth duration compared with O8 of OsN ...
... Crop plant architecture is an important agronomic trait that contributes greatly to crop yield. Tiller angle is one of the most critical components that determine crop plant architecture, which in turn substantially affects grain yield mainly owing to its large influence on plant density. Gravity is a fundamental physical force that acts on all organisms on earth. Plant organs sense gravity to con ...

Abstract:
... Despite the importance that environmental stress plays in the agronomic performance of plants, there is little agreement on its effect on bioactive compounds in tuber crops. A field study was carried out with eight diverse Chilean potato landraces and the commercial variety Désirée. Plants were subjected to drought stress for 6 weeks starting at 88 or 110 days after planting. As expected, the trea ...
... Knowledge of rice (Oryza sativa L.) genes and various DNA markers can be used in genomic breeding programs aimed at developing improved elite rice cultivars. We used an efficient genomic breeding approach to pyramid four resistance genes (Pi2, Xa23, Bph14, and Bph15) in the popular photoperiod- and thermo-sensitive genic male sterile (PTGMS) rice line Feng39S. We performed foreground selection for ...
... Soybean cyst nematode (SCN, Heterodera glycines Ichinohe) is the most economically damaging pathogen affecting soybean production worldwide. Host-induced gene silencing provides a promising approach to confer resistance to plant parasitic nematodes. In the present study, we produced stable transgenic soybean plants individually harboring the inverted repeats of three essential H. glycines genes, H ...
